Hi everybody! My question is the following: is a pre-pass with vqscale=2 a good indicator of the compressibility of a file? I have a collection of episodes 13 that I want to backup to a DVD+R. Obviously, I could simply calculate 4.38GB / 13, and have each episode use the same bitrate. However, I expect that some will require a higher bitrate than others. Hence the need for some sort of "compressibility measure": I could just do a pre-pass with vqscale=2, and use the resulting file size to calculate the proportion of the available space which should be given to the episode. Thanks in advance for yor time! Cheers, Jean __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
