Hi

I have a sample of a movie which is about 1 minutes and 31 seconds long, when playing the sample in Windows Media Player.

But if I load it into Sonic Foundry Vegas 4.0 it's only 1 min and 13 sec long, but the audio track is 1 min and 31 sec long!
The whole movie is there, but the video is out of synch with the audio!

The sample is Mpeg 2 format, with a frames per seconds of 25, but Vegas turnes the movie up to 29-30 frames per seconds, why? how do I turn this off?


I've tried adding the sample to Sonic Architect, and it does the exact same thing! i want my sample to have a frame rate of 25!!! not 29-30 !!

Help!!!!!!!!!!!!!!!!!

Have you looked at your project properties.

They will be NTSC (29.97fps)by default unless you have changed them to PAL (25fps)

yes I checked. I've tried to change it to 25 but the program still thinks that the sample is in 29 frames per seconds.

I've tried some other movie files, they are incoded in mpeg 1 and works fine. They to are incoded in 25 frames per seconds.

In windows media player, the sample works perfect..

Strange....

Hi SNash,

How would you feel about sending me the file? (<5MB)

If you like I can peek at it, see what I can find.

vegaschains at yahoo dot com

Please post here if you send...

Thanks for the offer, but the files 40 mb!! :)

I'm figuring out what the problem is. maybe I'm using a wrong Codec or something.. Do you know how to change which mpeg 2 codec Vegas uses??

Is there a way to force a clip to run 25 frames per seconds??

I don't think you can change the codec that VV4 uses for mpeg2. If you had the codec that originally created the video file, you might be able to tell windows to use another extension for files encoded using that encoder, then import it into VV4, & it *might* work.

Before that I'd try the programs that change the header info &/or repair the existing mpeg2 file. There are too many to list here - go to digital-digest.com. Most of these don't alter the existing video itself (I'd still back it up), but change the information part of the file that VV4 reads as 29.97

Hi,


A 40MB Mpeg2 file that's only 1:31?


wow.


Vegas uses the MC codec, I don't know how to change that.

What program do you have that could for example change the frame rate of 29.97 to 25 ? ? ?

If you feel that this is a legit MPEG, we'd like to get a sample of it so we can figure out if there's something wrong with our MPEG reader.

Here's something you can try, to fix the short video that playing too fast. Turn ON "Ignore Event Grouping" in the toolbar or Options menu. Click at the end of the audio event to set the cursor there. Ctrl+drag the end of the video event until it snaps to the cursor. You've just slowed down the video to end at the same time as the audio.
