Help me find a tool to stretch audio to fit video

Postby MyK on Mon Mar 12, 2007 2:49 pm

Hi guys, now it's my turn to ask for your help regarding video/audio tools. My problem is I downloaded "The Beast from 20.000 Fathoms" that was a dual audio release. Once I removed that Spanish audio with VirtualDubMod what remained was a video file that has unsynced audio (MP3) and starts 5 sec too early and ends about 7 sec too late... Anyway, tried using stretch audio filter in VirtualDubMod and realized it will only try to adjust audio sample rate so it will end at the same time the video ends. What I get this way is synced audio only at the beginning of a video file. Demuxing and then cutting the video or audio file is not an option here, because I had great trouble finding exact positions to sync even the beginning of file, let alone what I'd all have to do to sync its end... My question: is there any tool that would allow me to sync audio/video manually and not demand constant trial & error procedure from me? Thanks in advance!

was the audio synced before you started to fiddle with the spanish audio track?

Nope, it was out of sync beforehand, I just overwrote the header as VirtualDub(Mod) will ask you to do if audio is VBR, disabled the Spanish audio and direct-streamed both audio & video to a new file (just to make sure my player isn't the culprit). And original (English) audio was the second stream not the first so nobody must've noticed before for this rare stinker ;)

How on Caprica could I have ever missed that release beats me :? Thanks Jynks :D One problem solved, but that original question still stands, cuz I have more bad rips like this one I mentioned. Any ideas on how to do that? Is there any tool for it at all or must I really write my own filter (for which I don't have any spare time ATM), include it in custom DS graph and then capture audio stream from output and stream it to a wav file? I know it sounds easy for any programmers here but trust me it takes days to fiddle with it and get it right. Also, changing sample rate ain't easy if you want it to sound OK :(

YAAI will stretch & resync your audio, takes a bit to get it right but it deffo does the trick, used it for both in the past but mainly for resyncing...

Yeah, I'm familiar with YAAI cuz it's written with Borland's developing tools that I also play with... which would be all roses except for the fact that I simply l00ve to play around with direct show filters and have accidentally misconfigured some of those that YAAI uses and is now unable to connect input with output :lol: Will have to look into it once, but since playback is fine and VirtualDubMod works well too (so far hehe) that could take ages... Thanks for the link anyway, and since it's a GNU open source project, who knows, maybe one day I'll find time and fiddle with it's code so you better prepare for the doomsday scenario :mrgreen:
