Audio-video delay with autogk 2.6?

[graidia]

hi

i'm using autogk 2.26 for converting my recorded Mpeg2 files from my satellite card ( Skystar2), i'm glad because the video result is great however i have a problem of the synchronisation between video and audio ( the audio is in avance to the video)???

i remenber when i'm used to use virtualdub only for the conversion, there is a parameter in audio interliving that make a good video/audio synchronisation, but as you know autogk is using virtualdubmod and i can not find the audio interliving option?

please can someone help to get video sunchronized with audio?

thanks in advance for your help:thanks:

Hello, and welcome to the forum.

Perhaps you mean AutoGK 2.26? The current release is 2.27. :)

There have been a number of threads in this forum on this subject; it is a common issue with certain discs.

In both linked threads, the very first response is setarip_old's, which clearly and accurately details the procedure.

Where is your AutoGK log file?

[graidia]

i'll try tomorrow to bring u the Autogk log files
today i've tried gordian knot and i got the same problem like autogk :(

I tried also encoding an Mpeg2 files using virtualdubmod only and the file is ok the sound and the video are synchronized.
i guess that my problem is due to the autogk?

PLease help

[CWR03]

Have you attempted the procedures listed in the linked thread?

[graidia]

yes i tried but no result :(
it seems that the delay is to great -47721665ms (http://www.kirikoo.net/images/7graidia-20060526-083440.jpg)
all the files converted with autogk and Gk have this same delay (-47721665ms) why?

is autogk does have a problem with mpeg2 dvb files?

[setarip_old]

Hi!it seems that the delay is to great -47721665msif you watch and listen to the .AVI, is it REALLY out of synch by 47,721 seconds (Over 13 HOURS)?

I'm guessing this is not actually the case - and a false delay is being indicated. If the TRUE delay is a matter of seconds or less, you certainly can correct it by following either of my posts in the two links provided in Post #2 in this thread...

[graidia]

Hi setarip_old
This problem happens only with my dvb MPEG2 recorded files ( recorded with my skystar2 sat card)
for the little files ( from 5 to 10 min ) when i play the generated avi files, i can't hear any thing it seems like the files are recorded without sound.
for the long files ( from 1 to ....hours) when play the avi files there is a sound but the audio is delayed too much so i can't correct it with audio interleaving.

Yestaerday i tested an MPEG2 files ( not from my dvb card) and i noticed that the delay was 0 ms.

Now i think that autogk has a problem with my dvb mpeg2 files?
Any one have an idea?

thanks;)

[setarip_old]

If you PLAY the captured dvb MPEG2 file, is the audio in synch with the video?

[graidia]

hi
yes the MPEG2 is well synchronized.

[CWR03]

Why not upload a small segment of one of your original files so someone can examine it? I prefer www.badongo.com, which is free and you won't have to wait for moderator approval.

[setarip_old]

yes the MPEG2 is well synchronized.Then there is likely some type of header information in the dvb file format that is misleading to or misinterpreted by AutoGK.

By all means, if possible, follow the upload suggestion made by "CWR03"...

[Hobojobo]

hi
yes the MPEG2 is well synchronized.

Do you prepare the dvb mpeg2 before you feed them into AutoGK.

I use the SkyStar2 as well for recording.
Then I use ProjectX to demux/repair the mpegs.
Before using AutoGK the video and audio have to be muxed again, of course.

Have you tried ProjectX, to check the mpeg2 for errors?

[graidia]

Hi

Have you tried ProjectX, to check the mpeg2 for errors?

No, i don't use any correction before i convert my files to avi , but i'll try.
i've found a temporary solution to get synchronized avi files:

1-i open my mpeg2 files using virtualdubmod

2-then i save save the audio stream as wave file.

3-I run autogk and i convert the mpeg file

4- when conversion is done, i open the avi file via virtualdubmod, i keep the video as direct stream copy, and the audio as full processing mode;
5-i add a new stream in the stram list ( my saved wav file)
6-i set the audio compresion to mp3
7-i save the file to a new one

this way i get a well synchronized avi file.

i will try projectX and i'll tell u about the result.

thanks for your help
