Audio synch issue in AutoGKnot 2.20?

[deathadder]

I was using AutoGKnot quite successfully for a while but this last week three different encoding done shows Audio Synch issue. I was wondering if anyone can point me to how I can fix this.

Here is an example log file out of AutoGknot as a reference.

Thanks in advance.

Hmmm, wondering why your Target Size is set so high?

Anyway, wondering what playback method you are using; maybe you should try CBR MP3 as some players have trouble w/VBR.

It looks like this is not FILM footage, but NTSC Footage that needs to be IVTC'd. Did you try the Force IVTC option in the hidden options of AutoGK?

Cheers!

No I did not. I will try it (using CTRL F9).

I tried using force ivtc and there was no change.

The dreaded sync problem is a common theme with quite a few threads and posts.

Older versions of DVDfabDecryptor had some problems with some disks re audio sync. The latest version (check the DVD news home page) should have fixed this but I haven't had the chance to test it. :(

Further rumours suggest the updated version of LAME is to blame (seems unlikely). Lastly you could try running FixVTS (in DVD mode) and maybe VOBblanker over your ripped files prior to encoding to ensure the DVD structure is correct.

What movie are you trying to backup?

Cheers!

I do not think anything is wrong with the source. I tried nero digital and it worked fine. Though I do not like nero digital..

[Stan78]

I was having the same problem with 2.20. Like, every other avi I made had the audio out of synch on it. Try getting the latest AutoGK. I'm using 2.26 now and so far no problems. I think there is some issue with 2.20. I tried everything else. It wasn't the source files that were bad. They'd work with everything else otherwise.

It's easy to fix your audio on the ones you already have, if you still have them. You can do it in Virtualdub. That's what I did. Open the avi in Vdub and click on the Audio button at the top. Select Interleaving and where it says "Delay audio track", put in positive or negative values, depending on if the audio is early or late. 1000 is equal to + 1 second, and -1000 is equal to - 1 second. Try some value, select OK. Then again under the audio tab make sure "direct stream copy" is selected. Do the same for the Video with making sure "direct steam copy" is selected. Then under File tab, select "save as avi"

It's really easy and quick and then you don't have to re-encode. You should probably make sure you don't overwrite the original avi when you do this, because you'll likely not get it perfect the first time. You can fix your bad ones this way, but I'd uninstall 2.20 and try the latest version.
G-luck

see my post for a solution!

this is a technique i just worked out and so far have had 100% success

Thanks Stan78 and Kristijan08. I will try both solutions.

Deathadder,


I tried the new version of AutoGK (v2.26) after uninstalling v2.20. This did not solve the problem.

I also tried fixing the sync issue in Vdub. I could not fix this because the audio offset did not seem to be linear. That is if one synched the audio and video close to the begining of the clip it was still off towards the end.

Anyhow I am going to try the dvdshrink solution next.

Just giving you feedback.

Thanks,

R

I have the exact same problem.

The most confusing thing is that the delay is not linear throughout the avi file.
The source is fine.

I've had this on about 10 out of the last 15 encodes I've done.
The source is usually a avi file (e.g. TV-rip) that I'm reencoding to a smaller size for viewing on my portable viewer.

[CWR03]

Audio synch is a common problem when encoding from TV captures because many cards rely on the CPU clock for timing, which isn't accurate enough. It's not a problem with AutoGK at all. The only way you're likely to get a good encode is to use another capture software other than the one supplied by the device manufacturer - capturing directly with VirtualDubMod should work.

[kie]

But the TV encode are synced fine until I try to convert them with autogk...

[CWR03]

So do mine - whatever keeps them synched in their original format is lost in the conversion.
