A/V out of sync, despite using various techniques |

| Hi all,
This is confusing, as I had this problem in the past, but it was resolved using FixVTS. This time, it's not helping. I'm trying to convert DVD to AVI. The full DVD is stored on my hard drive. It was copied to my computer using DVDFab. Although I think DVDFab does it for you, I removed the encryption/protection with FreeDVD. All my backed up DVDs play fine, including the one I'm trying to rip. I used AutoGK to create the AVI. It used XviD, a fixed width of 512, the original AC3 and a file size of 750 Megs. The AVI's audio and video are out of sync. The last time this happened, someone on the site recommended using FixVTS, prior to ripping and it worked. This time it isn't helping :( I'm attaching a sample from the AVI, in case that'll help anyone. Thanks for any assistance you can provide, Justin clip.avi |

| Sometimes it's just easier to fix the audio delay rather than try and figure out how and why it got out-of-synch. Assuming the delay is constant throughout the entire movie, run it through VDubMod again with the video set for Direct Stream Copy and a delay of -1100ms for the audio. |

| Sorry for the lack of reply,
Your suggestion worked, so the least I can do is go back and say "Thanks!" :-D Question: How did you know that -1100ms is what seems to be THE perfect amount of delay? By viewing it after applying that delay, it looks like there was never any problem at all! |

| I used the +/- keys of MPCHC to adjust the delay on the fly until it 'seemed' right. Since most people will find it OK if it's within 100ms or so either way, you don't really have to be completely accurate. To be even more accurate (better synch than just using voices), find a sharp noise - one like a gunshot, something being struck, like with a hammer, or some other kind of sharp noise. Then you can get it pretty close by synching on that. |
