Ive recently come across another problem, which is driving me beyond despair.
Whilst making some videos using multiple short clips, the voice/sound of these clips is gradually getting out of sync with the video picture.
THIS IS ONLY happening when rendered out to AVI with WMV 9 codec compression. Ive tried rendering the same project to MPEG-1, MPEG-2, realmedia and WMV. I dont have the same problem with those. Ive even tried to render portions of the project in the hope that its a problem with the individual clips. Its not. The individual clips use uncompressed AVI code and play audio insync with the video.
Ive tried to LOCK each item in place and buffer out parts of the timeline with muted soundbite (AVI) to try to get the audio to play in sync, but alas it hasnt work.
To give you an idea of how the end project turns out, the audio appears to quicken pace around 30secs, and seems to play at 1.5x the spd it should, hence by the end of the video, the audio is out of sync.
However, I have a music track on a seperate track which plays perfectly well against the video clips in the sequence they play in. It is just some incompatibility with the audio portion of the clips and rendering them to WMV9.
Does anyone know what this issue might be? Or how to solve it!
