i converted my parents' old beta tapes with home movies into xvid format since their dvd player plays divx/xvid...i used a dazzle dvc-80 and the pinnacle software to move the movies over into dvd format (one file, no menus, etc.) and then autogk to convert them to xvid...problem i get is that SOME (not all!) of the movies have audio skewing...the single dvd file plays fine in wmp, but the converted files are funky

i do my audio in vbr-128 and at first i thought that was the problem...so i re-encode with cbr...still the same problem

suggestions? i've tried demuxing the avi into the video and audio (wav), but (obviously) the amount of time in the video and the amount of time in the audio differ...suggestions? is there a (preferably free) program out there that is actually pretty good at re-synching?

i've tried virtualdub...it doesn't play well with mp3 streams...especially vbr

anyone every used the virtualdubmod?

ahahahaha good luck

you've lost all keyframe associations


welcome to my life of hell circa thanksgiving week

the only thing i can find online has to do with ripping dvds and some sort of empty cell thing...but that's no use to me because they're from beta tapes...know of any software that will allow you to insert empty space into a wav/mp3?

well, I've used pinnacle in passing and I dont ever remember it being able to set keyframes for you to keep your audio in sync. You could maybe look for a copy of Adobe Premiere Elements or something and see if that does. I know Premiere full will for sure.


or you could always just shoot yourself in the face, that's what I wanted to do when I was doing the shit I was doing

I tried to dabble in video editing...for about 30 minutes...and I can't figure out why it's so damn hard. Seems like it would be real simple...or, is it real simple with expensive software?

12/17/2006 4:05:37 PM

it can be simple, and it can be fucking hard as shit. it really depends on what you're trying to do. what he's trying to do here is one of those things that's hard as shit.

12/17/2006 5:41:28 PM

You didn't understand my question. I understand the status quo is it can be hard as shit. What I am saying is, fundamentally, why is this hard?

12/18/2006 4:23:01 AM

well, using this situation as an example:

He's trying to sync two non-associated audio and video streams. Normally this is done with keyframes that let the video player know what audio should be playing while frame "x" is displayed. Keyframes are why you can watch a streaming video from the internet or something and hear the audio fine while the picture is all herky-jerky. They tell the video file to skip ahead when certain audio points are hit.

The hard thing about taking audio and trying to sync it with video is that a lot of times the audio track's length can be different from the video track's, or it could have a slightly different playback speed, or any number of other things.

Depending on what codec you're trying to encode to, you're also going to lose a lot of data in compression. Frames drop from video, sections of audio end up with lossy VBR going on, etc etc etc.

In practical application, this means that even if you have the audio synced up in one portion of the file, in others it could be off by seconds or tens of seconds.


ok I just got completely bored typing this out, sorry.


I hope you at least get the gist of it though

this is ridiculously annoying...anyway, trying the method from this site, which may help (although i THINK the skewing gets worse as it goes along)
