MPEG-4 vs wave

Mancaverecordings wrote on 2/5/2013, 6:41 PM

Ok, so I have this project. I have video clip as I have done hundreds of times. I import audio (This a film of girl in studio lip singing to her recording) but I cannot get them to sync. I've done this so many times. I do it by eye. The recording she is lip singing to is same that I have imported. It starts out fine then after 10 seconds or so it gets off. The audio I was given is an MPEG-4. I typically use wave files created by myself. If you listen and look at wave forms in Vegas, the audio I was given is longer than camcorder audio. This make sense to anyone? Windows 7 by the way.

Thanks

24 posts, and still no file specs?
[sigh]

Suit yourself, and best of luck.

Musicvid,

I believe there have been posted spec's. Not sure what more you need to help?

Mancaverecordings:

Thanks. I just prefer to work through all the obvious but often overlooked before jumping into the less obvious.

On the one hand it'd be interesting to really know what's gone wrong where, you may well have struck a bug in Protools or Vegas although it's hard to imagine something so basic going wrong. On the other hand as others have suggested, just get a wave file from the studio and (hopefully) move on.

I have a policy of not accepting anything but wave files, especially from people who know what I'm talking about.

Yeah thanks Bob, me too. Only wave. Like I said I've never run into this before but I always record all audio myself in Protools, then bounce to disc in a wave and save to my computer in projects folder. Then import that audio wave into Vegas Pro 9 which is on same computer asd Protools. Yes it must the the MPEG-4 that is the issue. I did not realise there would be slight difference in overall lenght of tune between the two. Wave is on the way. I'll keep interested undated!

Thanks

Bit of a strange issue.

When I helped my cousin's band do its promos - I had them swear on a stack of bible that the audio track they were lip-syncing and recorded by the camera mic would be the exact same track that would be used later. Since they're a bar band and were doing a medley-style promo, they produced the mastered audio track *first*, then filmed. Since the audio source track was the same - syncing up the mastered audio track to the camera mic reference, via pluraleyes, worked flawlessly.

Mancaverecordings,
Those are not file properties. These are file properties. You haven't even told us the codecs used! But I'm through beating my head against a brick wall. Best.General
