x264vfw always compresses at 24 bit color depth. There is a choise "keep input color space". But what about color depth? how to keep it at source bit depth? decrease or increase? or what is the command for that? and also i tried on MeGui's x264 but it always keeps at 12 bit. So important question is: how to compress video at source bit depth in x264vfw?

megui uses x264 which can only be compiled with 8 or 10 bit at compile time. Not 12. (8 and 10 are the only options for x264)
The "12" is a different style of notation indicating 8bit, subsampled 4:2:0, but really still means 8bits per channel . (Since U, V are 1/2 in each dimension, it's 1/4 of 8, or 2. So 8+2+2=12. By this logic, 8bit 4:4:4 would be 24)
