What is the file size difference between 8 bit and 10 bit raw video? How much color information does a 8 bit pixel need compared to an 10 bit pixel? What is the difference. As an example how much file size would an single 640x480 frame take if had 10 bit color instead of an 8 bit colour
Instead of 8 bits per every channel and per every pixel you need 10 bits, which is 25 % increase of the raw footage.
Since the size of 8-bit raw footage is as such huge enough, 25 % of it is high enough price, isn't it?
