Had a strange problem with an avi encode--25 fps, Divx 5.02, 2 hour movie, split off audio with virtualdub as wav and converted to mp2 with Headac3he. Encoded video with TmpgEnc using kvcdx3 mpeg-1 (at 544x576 25 fps) and muxed with BBMPEG. When I played the resulting file on the computer it's in sync, but after burning to CD (w/ Nero) the audio is ahead of the video by about .5 sec. I solved it by having TmpgEnc start about 10 frames into the movie, and the resulting muxed file played fine on my standalone (Apex 1500), but the audio was behind the video on my computer!

Anyone have any idea why this is happening? I haven't had this problem on any other encoding I've ever done.

hi heller,

the audio was encoded as mp2 44.1k or 48k in Headac3he?

if now is 48k, resample to 44.1k and try again.

Thanks for the suggestion jorel.

I did resample to 44.1 with Headac3he, and still had the problem.

Just can't figure out why this would be the case...

hi again heller!

burning as svcd mpeg2 in nero,
in my player with 352(or more)x480 the audio is out of sincro using 48k mp2.
then i only reencode the audio to 44k and burn in nero again and all is ok!
only in 352x240 mpeg1,the audio 48k works! more than this resolution, the audio loose the sincro!

some people burning with " vcdeasy " say that this is the solution for this problem,
but i don't try it yet!
do you want burn with vcdeasy to try?
