Audio & Video Matching

[maddog666]

Hello, I've been trying to convert some AVI (divx) to MPEG 2 with cce. I want to treat audio & video separated, so I can work with DVD authoring softwares and use stuff like ac3 audio. The problem is that my converted mpeg gets a diferent number of frames and time in seconds from the original one, it's some seconds lower than the original avi. That's a big problem for me, since whe audio wont match the video perfectly anymore. I tried lots of diferent things, with a 3 4 GOP and diferent conversions options.

Original avi time is: 1:15:58
Original avi wav (got it out with full processing in virtual dub: 1:15:58

converted mpeg is..1:15:54

any ideas ?

iirc, in the CCE changelog there is a mention of a fix where it used to chop of the last frame (maybe a little more).

I tried two diferent versions of CCE, the newest one and an old one. Both do the same thing. I'm trying to encode the two avi I had joined separated now to see if it was a vdub join prob. The odd thing is that with TMPGENC it still had problems, but only 10 ms diference. (between audio and video)

This may not be of great help, but you can discover which frames were lost by jumping to certain frames in virtualdub and seeing whether the avi frame = the encoded mpeg frame.

You an open the encoded mpeg in virtualdub using a 2 line avs script:

LoadPlugin("H:\MPEG2Dec3.dll")
MPEG2source("H:\gingersnaps.d2v")
