The v641 has a four-megapixel 35mm-format CMOS sensor (which can capture 2560x1600 images at up to 1,450fps), and is smaller and lighter than its predecessor, the Phantom v640.
Other new features include: Dual power inputs for battery backup or hot-swapping batteries; a repositioned viewfinder port to make cabling cleaner and less intrusive; two auxiliary power ports that can provide 12v DC (1.5A) power for accessories – and each has an available trigger signal input; and dual cooling fans.
It has dual HD-SDI ports, which can be configured as a single dual-link 4:4:4 port. It includes 8GB of built in high-speed RAM with 16GB and 32GB versions also available. It can do extended dynamic range shots, capturing two different exposures within a single frame. Its native sensitivity is ISO 1000, which goes a little way to counter the significantly greater light needs of high-speed cinematography.
