Ok, first off, I have no idea what the video sampling size is or what is does, but I notice that after a clean install of my computer, and converting another movie to Divx5, the video sampling rate went from 24 to 16 bit. Before I reformatted my hard drive, I was getting a sampling rate of 24bit and now, I'm only getting 16bit. I also notice that using the compression test of Gordion Knot seems different. The percentages and bits/(pixels * frame) are way different than before. Is this a problem, and if it is, what is the fix? Thanks.
