Audio not in Sync after conversion (SOLVED)

[ricardo.santos]

Hi everyone!

Im trying to convert an xvid file to dvd, ive tried to do it manually with Quenc and TMpgenc, tried all in one click programs: favc,d2mp,avi2dvd,dvdflick etc but no matter what i do audio isnt in sync with the video.

insted of converting to pal i tried to stay with ntsc but it doesnt help.

Does anyone have any ideas on what im doing wrong?

Thanks

Try a "save" with "direct stream copy" in virtualdubmod before anything.

enjoy,

Thanks for the advice MTZ!

Just tried the "direct stream copy" tip but it didnt work, so i looked at my final tool "convertxtodvd", i tried it once and i didnt like its quality, i downloaded teh trial version and to my surprise it detect a sync problem (picture) and corrected it.

how can i fix that error using the opensource/freeware avi to dvd tools?

Thanks

Hi!

1) Most obvious question - Does the XVID play properly synchronized?

2) When you tried the suggestion by "Mtz", did you remember to set "Video">>"Framerate" to "Change so audio and video durations match"?

3) Why, if you're in Portugal, did you create the XVID as NTSC, rather than PAL? Which was the source material for the XVID a DVD, a video capture, or camcorder material?

I spy vbr mp3. When using FAVC if you go to the last tab (Advanced Scripting) and tick the box marked "Use DirectShowSource instead of AVISource" that may solve the problem.

http://forum.videohelp.com/viewtopic...338598#1338598Does FAVC use EnsureVBRMP3Sync() right after loading the source? It might save you from a lot of trouble (it's not only for VBR MP3's).

Oops. :confused:

(I hate being wrong. :p)

Yes it does.

yes, vlc and WMP play it fine

Hi!2) When you tried the suggestion by "Mtz", did you remember to set "Video">>"Framerate" to "Change so audio and video durations match"?

no, i will try that, thanks

This was one of first dvds i bought over the web a few years ago from Amazon, cant remember the tool i used to back it up so i dont know why its ntsc, this was a while back where i didnt understand a lot about backups, unfortunally the original dvd got scratched beyond repair thats why im converting the backup.

i always setup favc that way

i always setup favc that wayYou might want to try disabling DirectShowSource then.

Same result, out of sync audio

You might want to try disabling DirectShowSource then.

didnt work, still out of sync.

I left the trial version of Convertxtodvd overnight and it converted it keeping the audio in Sync.

It might no be something but it could be, on my experiments when i tried to feed the folowing avs to tmpgenc 2.5 it reported that there was no audio.

AVISource("C:\Documents and Settings\Administrador\Os meus documentos\clip1.avi")

[ricardo.santos]

This was the script that Favc produced, gspot reported the FPS being 23.976, so i edited the avs below to 23.976 and fed it to Quenc enabling it to create audio but audio was ahead of the video still.

.............

DirectShowSource("C:\Documents and Settings\Administrador\Os meus documentos\clip1.avi",FPS=23.979,ConvertFPS=True).EnsureVBRMP3Sync()
ConvertToYV12()
FAVCStereoDSS(Last,Last)

FAVCFPS(25,1)

FAVCResize(Last,"PAL",0,2250)

[Mr_Odwin]

The "FPS=23.979" is a bug that mediainfo picked up recently (I've reported it and it's fixed). It shouldn't really affect the audio sync though.
ConvertYV12() won't affect sync.
FAVCStereoDSS() won't change 48000Hz stereo audio.
FAVCFPS() won't affect the audio.
FAVCResize won't affect audio.

It seems Avisynth just doesn't like it. Try loading the file into AVI-Mux GUI and remuxing it - this sometimes helps.

Hi

avimux detected a delay in the audio, the same value that Convertxtodvd detected, to correct the value do i just save the file again? cant see any setting to correct the delay.

I saved the video again with avimux gui and processed it with FAVC and the audio is in sync with the video.

Thanks to
Mtz, setarip_old, Boulder and Mr_Odwin.
