Recorded mov and wav different lengths

Post by gavspav »

Just recorded a 2 minute clip from Resolume and I was surprised to find that the audio and video files created were different lengths according to Quick Time by over half a second.

Using QT I copied the video portion and scaled and pasted to the audio file which seems to have regained sync.

But I thought I'd let you know.

There was alot going on when I recorded it, perhaps that was it?

My experience is that you loose some (video)frames while recording in Avenue, especially if your PC.laptop is doing a lot of stuff.... So if set to 25 fps for example,it only record 15-20 fps every second. Same problem here. Which leave you with a shorter video file if played back @ 25 fps...

Yup, this is a known issue. Resolume will try to record the video at the highest framerate possible, but inherently there's a lot going on when you record, so usually it be lower than the audio framerate, causing different lenghts when finished. We are working on improving it, but this is the only solution for the time being.
