New Petrol Bags for cameras + audio


Petrol Bags will launch new audio and camera bags and accessories at NAB2013, (April 8-11 in Las Vegas), including a new backpack for compact camcorders, a bag for large cameras, mini LCD hoods for Canon’s C100, C300 and C500, and a large audio mixer bag.

The new Deca Airflow Camera Backpack (PC306 - pictured top) has a rainbow shape to allow air to flow through for greater comfort. It is designed for smaller camcorders up to the size of a Sony PMW-200. It also has a pocket for a 17-inch laptop and accessories. The main compartment has a run around heavy-duty zipper for easy camera access. Other features include sternum strap and padded waist straps for wearer comfort, and exterior pockets for extra storage.

The new Deca Camera and Accessories Bag (PA1000 - pictured above) has “an ultra-wide” opening, so that it can be used for fully equipped digital cinema cameras, such as the Sony F65 or Arri Alexa, or may be used as an accessories case.

Its internal structure is made from a one-piece honeycomb frame offering strength and protection for your equipment. It also features ergonomic interlocking grip handles and external top straps to secure a tripod.

Petrol is also launching Mini Hoods that are purpose-built for the Canon EOS C100 (PA1018) and C300/C500 (PA1016 - pictured above) to shade the LCD monitor on the popular digital cinema cameras. Both are constructed of lightweight nylon, with rigid internal panels. Sturdy black nylon binding straps should secure the Mini Hood firmly in place.

It is also launching a new raincover for the Canon EOS C100 (PR400 - pictured above).

Petrol’s sound equipment carriers have proven successful, so it is introducing the Deca Large Lightweight Audio Bag (PS617) that is designed for sound recordists who use the Sound Devices 664 mixer, with or without the CL6 Controller. This wearable carrier promises user comfort, safety, equipment organization, and practicality in the field.

Within the bag (pictured above), the mixer and controller are fully accessible and readouts are easily viewable. It offers a roomy, cushioned main compartment to safeguard delicate equipment. The standard removable internal divider accommodates the 664 Mixer and attached CL6 Controller, while offering easy access to the unit’s XLR connectors.

Come see us at BVE - free seminars


Broadcast Video Expo is Britain’s best conference and exhibition for anyone working in the video industry. It has lots of interesting FREE seminars to attend, and is probably the single best place to find out what is happening and make new contacts.

Previously it took place at Earls Court, which was ideal for those of us in what is a west-London-centric industry. However, this year it moves to the Excel Centre in distant east London, so it’s lucky that the seminars we’re taking part in aren’t early in the morning…

There are apparently 283 seminars in total (including those in specific manufacturer’s theatres), so BVE is a great opportunity for some free training. There are also supposed to be 331 exhibitors, so there is a lot to see and do – it’s worth making the journey.

We’ll be taking part in three sessions:


When we’ve done Q&A sessions at previous BVE conferences they have always been packed, so we’ve got another “ask the experts” session this year (Tuesday 5pm), with the assistance of some well known names to answer your questions on any aspect of production and post-production, covering cameras, audio, lighting, editing, and general production problems you may have.

We’ve got a group of independent experts to answer your questions, all experienced industry professionals and media trainers. The current line-up includes the ebullient Matt Davis - www.mdma.tv, the effervescent Alex Gollner - www.alex4D.com, and the ever audible Nick Way - www.nickway.co.uk (although as they are all freelance, that might change….), as well as ourselves. So do come along and bring your questions.

The clinic will be held in the Producers' Seminars Theatre from 17:00 - 17:45, 26 Feb 2013.


Christina will be taking part in one of the drop-in Skills Zone sessions on Wednesday at 4pm, to answer questions about running your own media business. The Skills Zone is worth checking out if you want to develop your career, as there are sessions about CV writing, tax, contracts, script writing, pitching, and starting out in cameras.

The seminar will be held in the Skills Zone Theatre from 16:00 - 16:45, 27 Feb 2013.


On Wednesday (5pm) Christina is giving her ever-popular talk on how to survive and even thrive as a freelancer in a digital, self-shooting world (this is always packed - as seen in the photo from last year, so come early if you want a seat….). It is particularly useful for anyone starting out in the industry, but there will probably be many things that will be useful for people who have even been freelance for several years.

It will cover all the essentials from getting work to getting paid, including the three most important lessons she has learnt as a freelancer…

The seminar will be held in the Producers' Seminars Theatre from 17:00 - 17:45, 27 Feb 2013.

Atomos makes the Connection

The recorder manufacturer, Atomos, is getting ready to ship its new HDMI to HD-SDI and HD-SDI to HDMI Connect converters, and has revealed plans to extend the range with other units, such as one to add XLR audio inputs to its recorders.

The converters, claimed to be the world’s smallest, each cost about £200, and can add HDMI inputs to the Samurai recorder or HD-SDI to the Ninja. Each will be able to fit in a mainstream Sony camcorder battery mount, and has a one-hour battery built in for stand-alone work. This also gives it continuous power when swapping the Sony NP battery that can power it for many more hours (12 on a small battery), and it can pass that power through to the recorder, light fitting, monitor or camcorder it is fitted to (meaning all of them can also be continuously powered). The 3G-ready convertors include Pulldown removal where necessary (60i to 24p and 30p; 50i to 25p), and an inbuilt test pattern and audio tone generation.

Atomos is now developing a range of Connect products “that add functionality to the recorders, but that only 10% to 20% of users need, such as XLR audio inputs,” said its CEO Jeromy Young (pictured with the Connect HDMI to HD-SDI converter).

Since Atomos shipped the Samurai in November, it has “outperformed my forecasts by about 8,000%,” and the company is only now beginning to match production to demand. By BVE it had released 11 free updates to the firmware for the Samurai, with another almost ready to ship. Future updates include off-speed recording (over- or under-cranked), while focus peaking, zebra stripes and false colour should be added by NAB.

“We’re pumping our money into development,” hiring extra engineers, he added.

One of its longer-term goals is an affordable 4:4:4 recorder. “The difference between even 8-bit 4:4:4 and 10-bit 4:2:2 is incredible. You can see the extra colour. But, the infrastructure isn’t there yet – as it isn’t for 50/60p,” said Young.

Audio: Paying the Digital Dividend

The re-allocation of frequencies for wireless audio in the UK and elsewhere in Europe could have hidden consequences for events and outside broadcast companies.

With the switchover from analogue to digital transmission, the EU and national regulators are keen to sell off spectrum to mobile operators.

However, this Digital Dividend will partly be paid for by the loss of frequencies for wireless microphone and talkback systems needed for outside broadcasts and other production use. I talked to some of the companies affected and my full article for the May issue of TVB Europe magazine is now online…

America’s Cup takes TV on-board

America’s Cup yachting will get a lot more close-up coverage starting with this year's preliminary races, thanks to the fitting of 40 HD cameras on competing yachts. 

As it progresses, there promises to be at least 80 on-board HD cameras and up to 200 microphones in place for the Louis Vuitton Cup and America's Cup in 2013.

Coverage will also include what the organisers, the America’s Cup Event Authority, are calling "a breakthrough in sports broadcasting – augmented reality from a helicopter." It is claimed that this will be the first time live graphic insertions have been done from a moving platform. Thanks to GPS, the systems will be able to track each yacht to 2cm accuracy, and show exactly which boat is in the lead – something that isn't always easy to discern in yachting, especially for fleet races.

“Extreme sport lovers will flock to this new America’s Cup because of the broadcast,” said ACEA Chairman, Richard Worth. “From heart-pounding manoeuvres at breakneck speeds to capsizes that result in two-story falls for the athletes, viewers will not just see the action, they will feel like they are right in it.”

UK OB specialists, SIS Live will design, supply, fit and maintain the cameras plus a 5.1 surround sound audio mix, and the wireless links needed to carry the signals from each yacht to shore.

The new-look race will use powerful, one-design AC45 catamarans for the initial races, starting in August in Portugal to early 2012, which can travel at up to 35mph (about 56kph). Then the ten teams will design and build their own AC72 catamarans for the Louis Vuitton Cup and America's Cup in 2013.

Each AC45 is likely to be fitted with at least four remote-controlled cameras, based on Sony modules with a 10x zoom lens. These will be fitted in waterproofed IP67 standard submersible housings (built into the design of the boat so that they don't get in the way) and cabled back to a central hub. Two video feeds will be routed from an onboard mixer, controlled via internet protocol, back to shore with embedded sound.

Five of the crew on each yacht will have radio microphones and belt packs, and there will also be various other microphones mounted around the boat for the surround sound mix. SIS intends to design its own 5.1 microphones for the races to cope with the salt water.

The RF camera links will be supplied by Gigawave, using diversity receivers and MPEG-4 encoding. Links will be fitted to helicopters, chase boats, mark boats and commentator boats, as well as the competing yachts.

The AC72s are likely to have at least five movable and three fixed cameras and double the number of microphones, with radio mics carried by as many as ten sailors. As each AC72 is going to be custom designed for each team, SIS will have to work with the teams to build the cameras into the yachts.

The America’s Cup World Series begins this summer and includes 16 regattas around the world; plus the Louis Vuitton Cup, the America’s Cup Challengers Series (July 13 – September 1, 2013), and America’s Cup Match (September 7 – 22, 2013) which will both take place in San Francisco.

Rycote suspends HD DSLR recorder

Rycote has launched what is claimed to be the first effective suspension mount for portable recorders, to isolate them from vibrations and handling noise.

Any portable recorder with a 1/4-inch screw thread can be mounted on the suspension, and attached to a microphone stand, boom pole or camera hot shoe – via a 3/8-inch Swivel Adaptor that allows it to be turned through 180°.

It is included as part of Rycote's new Portable Recorder Audio Kit (designed for use with the popular Zoom H4n recorder, which seems to be the number one choice of DSLR users). The kit includes a windshield designed for the H4n and a Soft-Grip extension handle for using the recorder handheld.

The 106g suspension unit is also available by itself and uses Rycote's Lyre design, which is claimed to offer "unequalled isolation and robustness". Unlike rubber or elastic suspensions the Lyre is unaffected by temperature extremes, and so can be used in harsh environments (with an operating temperature range of -20°C to 35°C).

Audio Developments DSLR mixer

Audio Developments' new AD071 Camera Mixer is small (13.5x9.5x4cm) light weight (400gm), and full of features.

It is envisaged that it will be used in a wide range of applications, but the main focus is for use with HD DSLRs – it has a mic level output on a 3.5mm jack socket for simple connection to a DSLR.

It is a 3-into-2 device with either microphone or line inputs, 48v Phantom power, balanced inputs and outputs on XLR connectors, switched routing, comprehensive aural monitoring of both direct and return signals, and two LED ladders for visual level indication.

Limiters are included in both the input and output signal paths to eliminate the need for having to use automatic gain control.

The mixer can be powered from either a 9v PP3 battery or from an external 9v to 15v DC source.

It costs about £750, and as DoP Mark Moreve (@mjmpictures on Twitter) pointed out, you can get something similar from JuicedLink (which he thinks is "fantastic") for less - indeed, you can have a ready-to-shoot JuicedLink DSLR Audio Bundle for about £500 including microphone and Rycote mount....

Free seminars - Join us at BVE 2011

If you are visiting BVE 2011 or The Production Show in London this week (Earl's Court 2 – 15-17 February), please come and say hello.

We'll be delivering our usual seminar (totally revised), Production on a budget, in the Production Theatre every morning at 10am – handy if you want to know which cameras you should have a look at later in the exhibition. We'll be talking about how to choose a camera for different budgets and for different types of production, and offering some tips on how to get the best from the technology. We will be putting up a pdf of the presentation after the first session on our main UrbanFox.tv website.

Also, on Tuesday, Christina will be telling How to survive as a freelancer (at 3pm in the Producer's Theatre – not the same place as our morning seminars), with advice on how to address such important aspects as getting paid, making a name for yourselves, and coping with taxes.

You won't need to pick up tickets for either session – just come along. Previously we've had lots of people standing at the back, or sitting on the floor, so it's probably worth coming early if you're interested (the picture above shows those who came early enough to get seats last year...).

There are many other worthwhile sessions available, free, in a load of seminar areas, although some will require you to queue up for tickets from the Seminar Registration desk (afternoon tickets can't be collected until after 12.30).

At the Production Theatre there will be sessions on multi-camera 3D, 3D commercials, file-based workflows, production management, shooting with a DSLR, and (at the end of each day) How to avoid becoming one of the 95% struggling Digital Film Makers from Den Lennie of F-Stop Academy.

At the Producer's Theatre there will be more on 3D (but aimed at producers), visual effects, getting programmes commissioned, casting, data workflow, drama production, and women in TV.

Also in the Production Show area is the Arri Production Skills Centre (which requires tickets), with sessions on the Arri Alexa, using filters, and lots on lighting, including Lighting on the Run and Energy Efficient Studio Lighting Techniques from the always enlightening Jonathan Harrison.

There is an even more extensive seminar programme at Broadcast Video Expo itself.

The 3D Revolution Programme (tickets required) includes sessions from such notable names as Phil Streather, CEO, Principal Large Format, Steve Schklair, CEO, 3ality Digital, and Chris Johns, Chief Engineer, BSkyB. There will be case studies, sessions on all aspects of 3D production and presentation, and a look at the future of 3D.

The Total Delivery Theatre (no tickets required) will look at IPTV, HTML5, Flash, mobile and online video. It will include a session on Thursday (13.30) by Rick Young, of Mac Video, on Broadcasting to the iPhone and iPad.

Broadcast Meets IT (tickets required) is aimed mainly at broadcasters, with many interesting and expert speakers on such topics as workflows, standards, cloud services, networking and infrastructure, Super-Hi Vision (Ultra HD), and several case studies.

The Audio Room (tickets required) will host a Radio Day on Tuesday, and over the following two days will look at such issues as sound recording, loudness measurement, workflows, wireless microphones, monitoring, audio over IP, and more.

The Post Production Theatre (tickets required), will have lots on 3D post, workflows, codecs, and where the industry is going (on Tuesday and Wednesday). On Thursday it will be devoted to Avid.

Sony's workshops will deal with: 3D Live Production; 35mm World; OLED Monitoring Technology; XDCAM File Based Acquisition; and Professional Audio.

Blackmagic Design will host DaVinci Resolve (colour grading) workshops, while Adobe's seminars will deal with all aspects of its CS5 suite (Premiere, Photoshop, After Effects, etc.).

BeachTek HD DSLR audio adapters

BeachTek now has two audio boxes for HD DSLRs that take XLR inputs, allow you to adjust levels, and route the result to the DSLR's mini-jack input.

The BeachTek DXA-5DA (pictured top) is a passive adapter, which doesn't have phantom power – you would use it with self-powered condenser microphones or wireless receivers, or as an interface to an audio mixer.

It has two inputs, a level meter, and a "unique AGC Disable feature controls the wild swings of the Auto Gain Control that plague most cameras," which reduces noise during quiet moments of recording so that you can record cleaner audio. It fits under the camera and can also be mounted to a tripod. It is powered by one 9-volt battery and costs about £290.

There is also the BeachTek DXA-SLR, with phantom power. It is similar, but without the little LCD meter display. It has Good/Peak signal indicators that show the ideal input levels at a glance, plus the AGC Disable feature. You can also monitor the playback audio from the camera. It costs about £350.

Also potentially useful is BeachTek's MultiMount 5D ($89), which provides four horizontal cold shoes and one vertical shoe for mounting microphones, wireless receiver, lights, etc. on your DSLR or camcorder. It is made of polycarbonate with metal shoe inserts and has threaded 1/4-inch/20 holes on all shoes for added flexibility. It also has a rubber mounting foot with locking plate for mechanical shock isolation, but it may not be advisable for use with heavier devices, which is why it also comes with an extra foot that provides a firmer mount.

Rycote boom poles go graphite

Rycote has introduced three new lightweight, telescopic carbon-fibre audio boom poles. The 1.63-metre-long G3, with three sections, and the 2.49-metre-long G5, with five sections. The G5 comes in two versions, a standard pole and one with an internal coiled cable and built-in Neutrik XLR connector in the hilt (pictured).

For several years, following its takeover of US boom pole manufacturer Lightwave Audio, Rycote has been selling telescopic boom poles under the Lightwave name. However, with the launch of the Rycote-branded G-series carbon-fibre poles, the entire range, including the A3 and A5 aluminium poles, will now be rebranded as Rycote products - Rycote is probably best known for its shock-mounts and windshields (we use a Softie on our gun mic).

The G-series poles use the same lightweight, patented, triple-cam grip and twist locking system as the A3 and A5 poles, and with no metal parts to add to their weight combine lightweight construction with tensile strength. As on the A3 and A5, the locking mechanism is designed to be resistant to jamming when the pole is dirty; however, if necessary, the locking collars can be completely stripped down for cleaning in the field if required. The G3 weighs just 360g, the standard G5 is 580g, while the G5 with internal cable weighs 720g - if you are holding a boom mic over your head for a long take, any weight saving is appreciated, and having the built in cable is one less thing to worry about or hear flapping in the wind....

List prices are G3: £150; G5 Standard: £204; and G5 with internal cable: £288, including VAT.

Røde’s VideoMic goes Pro

The original Røde VideoMic is widely used for video production, and is a particular favourite for HD DSLR users. Now there is a VideoMic Pro offering new features specific to professional video.

Noise transference has been significantly reduced using both a revised, more elegant shock mounting system and a lightweight premium cable.

The VMP is smaller (15cm long), weighs 85g, and is also centrally balanced, making it mosre suitable for use in conjunction with low-cost camera stabilisation systems.

It has a super-cardioid condenser microphone, integrated foam windshield, 3.5mm stereo mini-jack output (dual mono), two step High Pass Filter (flat, 80Hz), three-position level control (-10dB, 0, +20dB), uses a 9v battery offering up to 70 hours battery life (alkaline). It has a camera shoe mount with 3/8-inch thread for boompole mounting, and comes with a DeadCat VMP furry windshield.

It will be on show at BVE 2011 on stand C-44 (www.sourcedistribution.co.uk).

Wireless audio without interference

Shure’s upcoming Axient Wireless microphone system is claimed to be the first wireless system to both detect interference and automatically change frequencies to avoid interference.

“Uncertainty and volatility in the RF spectrum are the new reality for professional wireless users,” explained Sandy LaMantia, Shure's President and CEO. "They face increasing pressure to deliver interference-free performance even though conditions are more unpredictable than ever before. The Axient wireless system was designed from the outset to withstand interference from the analogue and digital sources that exist today and may exist in the future.”

The Axient system employs several new innovative technologies that work together to deliver interference-free audio at critical events, such as live broadcasts.

“Axient defines a new standard for control and confidence in applications with zero tolerance for failure,” added Erik Vaveris, Category Director for Wireless Products at Shure. “This is the first wireless microphone system that can detect interference and avoid it automatically. Today, when unexpected RF interference arises, an engineer is either stuck with dropouts or they can run a backup mic out to the performer. Axient makes that a thing of the past.”

Features include: Frequency Diversity, which transmits full-bandwidth audio on two separate frequencies to ensure seamless, uninterrupted audio for mission-critical channels, even in the face of direct RF interference; ShowLink remote control, which enables the user to make real-time remote adjustments from the receiver or a laptop, of transmitter settings like audio gain while the microphone is live; Axient Spectrum Manager, which constantly scans the RF environment, performs frequency compatibility calculations to assign clear frequencies to each wireless transmitter, and deploys backup frequencies automatically; Smart lithium-ion rechargeable battery packs; and Wireless Workbench 6, a new software interface that enables users to monitor and control the entire system.

“The Spectrum Manager functions as an air traffic controller for the system,” said Vaveris. “When the receiver’s Interference Detection & Avoidance feature senses interference, the Spectrum Manager assigns a new frequency that it knows is clean. The frequency is deployed to the transmitter by the ShowLink wireless access point, and the transmitter and receiver execute a synchronized frequency change in a matter of milliseconds, making it virtually undetectable. And with Frequency Diversity enabled, there is no audible trace whatsoever.”

The Axient Wireless microphone system will be available in mid-2011.

Tiny new Canon XA10 pro camcorder

Canon has developed its smallest-ever pro camcorder, the XA10, based on its new XF100/XF105 models, but without the 50Mbps recording.

The XA10 weighs just 820g, and the combined handle, XLR audio block, and built-in infra-red LED light, can be removed to make it even smaller and as unobtrusive as any consumer handycam if it is needed for undercover filming.

It uses the same lens, sensor, digital processor and focusing system as the XF100, in a smaller unit (the XF100 is already pretty small but almost twice the size of the XA10). It has a built-in 64GB solid-state drive (recording almost six hours at its highest 24Mbps bit rate) and has three seconds of cache recording. There are also two SD card slots, which can be used in relay or back-up modes where the XF100 uses larger CF cards and has no built-in drive.

The XA10 was launched at last week's Consumer Electronics Show in Las Vegas and should cost less than $2,000. It is attracting interest from professional users, such as UK rental house, Hireacamera.com, which sees it as the perfect replacement for the venerable Sony HVR-A1. "Our Sony A1s have been incredibly popular but we have for a while been waiting for something with which to replace them and here it is," it posted on its website. "We will definitely be stocking it from launch."

It uses a 1/3-inch CMOS sensor, records 1080p HD video in AVCHD or H.264 at 24 or 25p, 50i (or 30p/60i), and boasts good low light performance, down to 1.5 lux, as well as shooting infrared (like the XF100), helped by a diffuse LED IR emitter in the handle and a flip-up IR filter in front of the sensor. The 10x f1.8 30.4mm zoom lens has an 8-blade iris for an attractive bokeh (background blurring) effect. It can be used with Canon's new WD-H58W wide-angle adaptor, or other 58mm adaptors.

There is a 3.5-inch, 920K dot resolution, touch screen LCD, which can be used to select a subject for focus tracking and subject-specific auto exposure (which should mean that a white car crossing the background won't cause the exposure to change).

Advantages of XA10 compared to XF100/XF105:

  • Price - Under $2,000 (probably about £1,600) whereas the XF100 costs about $3,300 (or about £2,500) while the XF105 costs about $4,000 (or £3,200).
  • Size - The XF100 is hardly large, but the XA10 is barely bigger than a consumer camcorder, especially when the handle/audio block is taken off.
  • Internal memory - 64GB flash memory gives almost 6 hours of recording.
  • SDHC card slots (2) - adds flexibility of second media type, widely available at reasonable prices.
  • AVCHD - 24Mbps can give excellent pictures, especially if you aren't shooting fast-moving highly-detailed images, and takes up less than half the space of the XF's 50Mbps codec.
  • Easy to use - Those consumer camera features, such as touch auto focus and exposure, can be very useful. It is a pity that more professional cameras don't use a touch-screen interface.

Disadvantages of XA10 compared to XF100/XF105

  • Size - If you want to look professional and be taken seriously, the XF100 is about the minimum you should aim at. Also, a slightly heavier camera can be easier to keep steady - we've been using an XF105 for a few weeks and it sits very nicely in the hand if you need to go handheld.
  • SDHC - SD cards are tiny, and therefore even easier to lose than a Compact Flash card (which the XF range can take two of).
  • AVCHD - If you are shooting for broadcast, 24Mbps H.264 is just too compressed to hold up after being subjected to further compression for transmission - so you are more likely to see artefacts in detailed and/or fast-moving shots. The XF's 50Mbps codec has been accepted as HD quality by the BBC (although we don't know yet if the new single-sensor  XF100/XF105 will be too...). ALSO, AVCHD doesn't always play nicely with broadcast non-linear editing systems, such as Final Cut Pro, so will need to be transcoded.
  • 4:2:0 - The XA10 codec holds less colour detail than the 4:2:2 available to the XFs, which makes it a lot less suitable if you ever want to do green screen chromakey work.
  • Audio - The Dolby Digital two-channel (AC-3 2ch), 48kHz sampling used by the XA10 will probably be pretty good in reality, but the uncompressed PCM audio in the XF cameras will be even better.
  • Pro features - Although the XA10 is easier to use, the XF range has additional features that will prove very useful for many users, such as the variable frame rates (between 12 - 50 frames per second), or more assignable buttons (10 compared to 2).
  • 3D - The XF105 has a couple of 3D assist functions that make it very well suited for use in a 3D rig.
  • HD-SDI + Genlock - The XF105 also has these connections, allowing it to record at higher bitrates to an external recorder and to work well in a multi-camera shoot.

HF G10 costs even less...

Also new is Canon's high-end consumer camcorder, the $1,500 HF G10, which uses the same newly designed HD CMOS Pro image sensor as the XA10 to improve resolution, enhance low-light performance and expand dynamic range, thanks to using larger, more sensitive pixels – it is a native 1/3-inch 1920x1080 sensor rather than trying to cram more pixels into the sensor for higher-resolution stills images, as many camcorders now do. The sensor is also used in the three-chip XF300/XF305 models and is claimed to improve dynamic range by 280% compared to similar, more densely packed sensors.

The sensor is also used in the three models in Canon's compact new Vixia HF M-series camcorders (costing $650-$800 - the Canon HF M41 is pictured right). These will be able to be used with a $600 case waterproof to about 40m, for a reasonably priced underwater rig.

The HF G10 has 32GB internal storage plus two SD slots, 3.5-inch touchscreen, a built-in microphone that can zoom to match the lens (as on the XA10), and the same lens as the XA10. Useful pro features include: manual colour temperature adjustment (2,000K-15,000K in 100K increments), colour bars with test tone, manual shutter speed and aperture control, waveform monitor, a built-in Remote Control Terminal (which supports LANC protocol), and native 24p recording.

The XA10 and the other models mentioned should be available in March. The XF100/XF105 should start shipping before the end of January in Europe and in February for the US.

Also new from Canon is the Bluetooth-based WM-V1 Wireless Microphone usable at up to about 50m. The small microphone and receiver will be available in May for about $250.

DSLR v Video: Why not both?

A matter of choice: Gollner and Davis (and Canon 550D DSLR)

HD DSLRs are now widely used for video production, even for prominent TV series and movie making. Users love the shallow depth of field and low cost of entry. But just how useful are they for professional production, how do they compare to low-end video cameras, and can they withstand the introduction of large sensor video cameras that give the same look but without the operational problems?

"The tones of the images, the look, the range of lenses, the animation capability – they make these cameras a dream for independent filmmakers, but they're not good for everything. For the videographer who gets paid to shoot, run around, be quick, gather audio, videos, interviews. Quick turnaround. Guaranteed results, meaning its not going to screw up; the DSLRs have proved far from ideal," said Rick Young, editor/director/cameraman, MacVideo.TV.

For him it's not a matter of choosing one over the other, "they're both fantastic," but of choosing the right one for a particular shoot.

Producer/director, Matt Davis, MDMA, has a Sony EX1, and wanted to do wider shots. So, he bought expensive wide-angle adapters, but then worked out that a Canon 550D costs less than the adapter, even including the wide angle lens (he bought a Tokina 11-17mm zoom, which he praises for its sharpness). "The wide angle experience has been absolutely monumental. It does everything that an EX1 can't. There is no droop at the sides. It's got this wonderful panoramic feel. It is a smaller camera that can get into smaller places." He is only now investing in longer lenses.

"It had to work with an EX1. It couldn't just stand on its own looking beautiful and arty. It had to play fair with the rest of the video family." He makes sure that both the DSLR and the EX1 are shooting within similar contrast ranges "It's close, but it's not exact. It still needs a little bit of finishing off in Final Cut," to match the two pictures, but that is now quick and straightforward.

When he cuts the two together, it is difficult to spot the difference. The blacks can give the DSLR footage away. The EX1 can use Cine Gamma to give soft ramping in the blacks, and the DSLRs don't necessarily have that exposure range. "They're pretty and they're good, but they have limits, and you really can't push beyond those limits like you can with a decent broadcast camera," said Davis.

"If you look at DSLRs in isolation they look fantastic," said Young. "But when you put it together [with video], that's when you can really see the difference."

Young has augmented his two Sony EX1Rs and two JVC HM100s with two Canon 5D Mark IIs with Canon 16-35mm and Sigma 12-24mm lenses, "and it's staggering what you can get out of it. And even if I only use the DSLR for nothing but those wide shots, it would suit a fantastic purpose. The cost of buying a serious wide-angle lens for conventional video technology would be more than probably buying the whole DSLR package," he told the recent MacVideo Expo in London.

"We need this technology. It doesn't mean that it is everything; it complements what we've got, but it doesn't necessarily take over," although it has become "an integral part" of the kit he needs.

RAW deal: Young in a still from a demo sequence

Overcoming limitations

"It's just another tool, and it's a very exciting tool," said Den Lennie, founder, F.Stop Academy, who shoots with a wide range of cameras from Digital Betacam to XDCAM EX and DSLRs. He has produced four training DVDs dealing with HD DSLRs, but they have not all been shot using DSLRs. The 5D Mark II training videos were shot on a Sony XDCAM 350, while the Canon 7D DVD was shot on an EX1 and 5D Mark II.

"The limitations of DSLRs particularly lie in the audio," and when he was shooting in Malaysia with Dan Chung it was essentially a two hour documentary, which would have been much more difficult to do if he had to use a separate audio recorder (see some clips from it at www.dslrvideoonassignment.com). However, the training video uses both EX1 and DSLR footage cut together, which works very well. "You really don't have to do a lot of work [in post] if you match your cameras up beforehand," he added.

He tends to roll the sharpness, contrast and saturation down on the 5D Mark II, and bring a little back in post if necessary, and also roll down the detail settings on the EX1. The fundamentals of the craft of filmmaking remain the same whichever you use.

Alex Gollner, producer/director/editor, Alex4D.com (who has created a wide range of free Final Cut plug ins), now uses a Canon EOS 7D and 5D Mark II as his primary cameras, only occasionally using video cameras.

He likes to use a DSLR because he so often has to interview people in small rooms where the background would be distracting if he didn't have shallow depth of field. It also allows him use a very small lighting kit, enabling him to set up more quickly. He doesn't do news style material with it, where he would choose his HDV camcorders.

DSLRs give "blurred backgrounds behind my interviewee" and a "touch of class" to the result, he feels.

He uses a Zoom H4n recorder for audio and gets his subject to clap. "Synching only takes a few moments, as long as I don't stop and start the camera too often, and make sure they answer in less than 12 minutes," due to the file length restrictions.

He generally uses the camera locked off and just zooms in in post for close ups, as 720p is what most clients want the video delivered in.

When shooting on the EX1, Lennie uses a Tiffen low contrast filter to help smooth out some of the contrast so it matches better with the DSLR. "It is much easier to shoot on video where it's necessary to shoot in difficult conditions or where you are working as a one man band rather than using the Zoom recorder." If he has to synch DSLR audio in post, he uses PluralEyes (www.singularsoftware.com).

He filmed a concert recently for The Skids on five 7Ds, where the 12 minute recording limit was an issue (similar to shooting on film), so they staggered the recording on each camera by about 30 seconds and stopped/started recording one by one at the end of each track, for a two hour shoot. "You make a decision on what's right for the project," he said.

Davis feels that there is space for both proper video cameras and DSLRs at the moment, until the large sensor video cameras establish themselves. "I definitely do need both because there is no such thing as a single perfect camera." He finds that people react differently to stills and video cameras. Sometimes, if they see a DSLR, they may pose as if for stills, so you can get less posed reaction shots with a video camera.

Lennie doesn't worry about rolling shutter effects, as it's not an issue for most of what he shoots, while problems with moiré can be countered by using filters or defocusing. "It's just a limitation of the technology." He feels that DSLRs are particularly good for shooting in the back of a cab or other confined space.

Even with the Panasonic AF101 and Sony F3 coming along, Young feels that DSLRs still have some advantages, such as their compact size. He finds all of his cameras equally useful and they are used for different things.

Reflecting on glass

One problem, said Davis, is that a 50mm lens is not really a 50mm lens on cameras that use APS-C (which has a 1.5x or 1.6x crop factor) or Micro Four Thirds (2x) sensors. "The standard lens on a full frame camera is quite a long telephoto on a Four Thirds camera."

However, he feels that investing in glass will hold its value. "Glass can be a long term investment. The back end doesn't matter. Think about the front end."

"My clients are not going to see too much of a distinction in between video quality" on these cameras, said Gollner. It's more his own pride that makes the difference.

"If the client's images look better and they are paying less or the same for a higher quality product, that makes you look good," added Lennie.

Gollner believes that he could possibly achieve the same with DV or HDV, but it would take some extra work. "I'm just getting better quality pictures for a little less work than I used to a few years ago."

"It's all about the pictures […] who cares about what the camera is," added Lennie, "It doesn't really matter what you shoot on if you know how to shoot well."

"For extreme wides and extreme beauty shots," DSLRs "can't be beat," concluded Young, but for most other things, especially long record times and having all the right controls in the right place, he turns to his video cameras.
