Canon has filed a patent for RAW video
“The recording of successive frames of raw sensor data depicting a moving scene is provided. The raw sensor data comprises pixel data for an image sensor having pixels arranged in correspondence to a mosaic of plural different colors in a color filter array.”
EOSHD broke it down for people that like english.
- Designed for compatibility with CF cards
- Supports 4K and 2K video (4K is 4096×2048)
- Works with Bayer CMOS sensor (like the one in a DSLR)
- Sensor output is 12bit
Although current C300 camera has a 4K sensor, it cannot output a 4K image because most of the pixels are used to reconstruct colour without interpolation (made up pixels in-between).
