Sound lag on edited AVI file

[Splodge]

I imported an AVI file and edited two sections out. With the first segment, the sound and pic is fine. On the second segment, the sound now lags the pic by one second and on the third segment, the sound lags by two seconds.

I moved the sound track to the voice track and re-positioning the starting point successfully but when it renders, the sound lag pitches up again.

What am I doing wrong?

Welcome to the Forums,

First we are going to need some more information. Please view This Thread, it provides a guideline to the specific information needed to help you.

AVI is not a format by itself, it is a container or wrapper for a multitude of video formats. To determine which one, right-click on a clip either in the timeline or library, select Properties, and post them back here.

Hi Ron

Herewith the info as requested.

File
File format: MS AVI file --Open DML
File size 357,944 KB
Frame rate 23.976 fps
Duration 2554.221 sec
Data rate 138.58 kbps

Video
Compression XVID Mpeg-4 Codec
Attributes 24 bits, 624x352
Total frames 61,240

Audio
Compression 149 kbs, 48khz, stereo
Total samples 122,602,752 samples.

When I wanted to render the project, it gives you two options, either VS DVD PAL (720x576) or the same as first clip. First clip gives an error loading the codec, so I was forced to accept VS project settings. I got around this by using SuperC to convert the segments back to Mpeg-4

I tried rendering each segment individually and then re-joining them, still with the same lag. So the problem seems to be some glitch in the joining and then rendering.

Thanks

Gavin

There is your problem. Xvid is designed to be a view only format, it was not designed for editing.
Uncompressed "avi" = 65 Gigabytes per hour
compressed DV (avi) = 13 Gigabytes per hour
Xvid = 700 Megabytes per hour.

This problem has been raised countless times on the forum. The answer is to alter the Xvid to something less compressed dependant upon the final target of the video. If you are creating a Video DVD then you need to convert it to a DVD compliant MPEG2. Do a search of Google or your favourite search engine for an avi to mpeg2 converter program.
Some are free, some you have to purchase.

Thanks for the response. I will convert the Xvid to uncompressed and try again in another format and see what happens.

Was about to use the Colt Peacemaker on the screen!
