Sorry if this has been discussed already: looking to get a handle what the maximum possible data rate could be with raw recording. Since it claims "lossless", and assuming there will be situations where the footage will be near-uncompressible (however hard to believe that is), what are the sizes of uncompressed raw files? Actual (not effective) bits per pixel - 12 or 16?

If 16, then we're looking at 1920x1080 times six bytes per pixel times frame rate - 355.96MB/s at 30fps?

If those 12 bits are tightly packed, then it's 36 bits or five actual bytes per pixel - 296.63MB/s at 30fps?

Thanks!

Hi!

Why you count 6 bytes per pixel? Unfortanately sensor output 1 color per pixel not 3.
If it's 12 bit then it's 1.5 byte per pixel.
So uncompressed RAW Full HD 12 bit is about 89 MB per second (30 fps).

Btw since the fact sensor output one color per pixel 4K camera shall do the great job even to produce Full HD.

Thanks Andrey - didn't know this. Is this documented or discussed anywhere? (The type of color sampling the camera uses?)
