Friends,
I wish wisdom on the follwing
i have a 10 bit raw video avi that i wish to make 2 files
a 8 bit FFv1 in mkv and a 10 bit FFv1 in mkv.
My puzzle is that the 8bit file is larger in data size than the 10 bit file.
how is 1 min of 10bit FFv1 smaller than 1 min of 8bit ffv1
8 bit UUJA_Test_ffv1-8b-1m.mkv datasize= 127.7 MB
10 bit UUJA_Test_ffv1-10b-1m.mkv datasize= 123.7 MB
here is the output of creation and ffprobe of the resultant mkvs
Thanks
