However, these reference parameters on mplayerhq (http://www.mplayerhq...-example-settings) work pretty well on a sample H.246 file at apple.com. For the very high quality setting, the complete command would be something like `mencoder sample_iPod.m4v -o sample_iPod.avi -oac copy -ovc lavc -lavcopts codec=mpeg4:mbd=2:mv0:trell:v4mv:cbp:last_pred=3:predia=2:dia=2:vmax_b_frames=2:vb_strategy=1:precmp=2:cmp=2:subcmp=2:preme=2:qns=2` The resulting file is a chunk smaller and I can't see any obvious differences. The -oac flag covers audio conversion. "-oac copy" does not increase file size, but results in dropped frames. "-oac pcm" fixes the frame drops but blows up the file as it decompresses the audio.

Post #310,068 by drook 6/23/09 8:32:24 PM Reply	Nope This is the little HP mini-desktop I picked up for $100. By the way, it finally finished and the quality is good. I haven't taken a copy downstairs to confirm it plays on the new TV -- that's what I was converting it for -- but it is mpg now, and if the quality is different, I can't tell. -- Drew
