Audio out of sync with many recorders.

[Darth Irule]

Hello. I have recently been trying to record some footage of video games from my computer. I have bought a FRAPS license and noticed that the audio and video slowly get out of sync as the video progresses. I have tried recording with different frame rates and resolutions but I still get the same result.

So I downloaded a trial of Camtasia. I recorded some stuff with that, and I got the same problem. The further the video went, the more it became out of sync.


The only way I know how to fix this is too manual sync the clips together in a video editing program. But that takes up a lot of time where I can be doing other things.

Anyone know why this is happening and how to fix it?

The audio is delayed. An event happens in the video and then the audio of the event follows after.
