audio/video synch problems

[madesther]

When I convert an AVI Divx movie to MPG VCD with TMPGEnc the audio and video are not synchronised anymore. The audio is 3 seconds behind the video. Does anybody knows how this can be fixed?

Thanks,

Ernie

I am having exactly the same problem, I think you have to demux using tMPGe then use bbMPEG to "remux".

I haven't attempted it yet as I really dont know what settings I should be choosing. Im looking for instructions at the moment.

What version of tMPGe are you using ? I can only assume that everyone gets this problem when converting ?

'When I convert an AVI Divx movie to MPG VCD with TMPGEnc the audio and video are not synchronised anymore. The audio is 3 seconds behind the video. Does anybody knows how this can be fixed? '

is the sound sync (1)off through the whole vid or does it (2) start out ok and get worse as the vid plays?

if #2 then you probably would benifit from loading the vid in virtualdub... setting audio to [x] full processing and choosing the 'save wav file' option... then in tmpgenc use the avi as vid source and using the wav file as sound source

or you could just have tmpgenc just encode the sound (using the (o)audio only tab instead of (o)stream(audio/video) tab .. you load up the wav.. (browse in the audio spot) and encode.. tmpgenc will make an mp2 which is ready to multiplex with your mpeg video

if option 1 is the problem then what 'I' would do is... demux ..load the audio into an audio editor that takes mp2s's and cut out the lag.. then remux. i like cool edit so i convert the mp2 to wav.. edit with cool edit then convert it back to mp2 (using tmpgenc in audio only mode as outlined above) then remux (multiplex)

i had a vid just yesterday that was pasted together poorly by the origional author. played fine in wmp. but 3/4 of the way in (after an edited section) the audio went off by 1/4 of a second. i tried every trick in the book before i looked at the vid again and realized it was a sudden loss of sync, not a slow one. (again.. the origional avi played fine .. but the problem happened when i encoded with tmpgenc straight and when i frameserved tmpgenc with virtualdub.) so.. demux.. decode sound to wav edit 1/4 second of sound out at that edit point - save - encode to mp2 and remux.. and viola... sync back.. nero took it happily and away we burn

oh.. and (if i even need to say it) make sure when you encode the mp2 with tmpgenc its at vcd specs

Mpeg-1 Audio Layer II
44100 hz
stereo
192 kb/s

(should be default that way) but just make sure

w00kiee,

Thanks, that tip fixed one of my problems, but I have another problem. I did a rip and I noticed later in the movie, I get get "picture shaking", espesically when people are moving around. I am using TMPGEnc 2.0 to do the rip.

Is there a setting that will fix this?

Thanks

dunno much about ripping d00d (im assuming you mean dvd) not capturing from a tv signal) could have something to do with interlacing.. but i wont speculate further. check out the dvd rip section to the left
