ok. In fact such a problem is on of the hard to fix, as we could not replicate it so far.
I suspect it depends on certain GPU, and audio drivers used. Currently we are gathering statistics of such kind of problems. So, could you please upload us the clip you made and tell us what OS 32/64 bits you have?

I have done this and the speech is one second (Pretty much exactly) ahead of the video.

Hi Watkins577,

Ok, in this case could you make same test with microphone capturing? from time to time say there the time position, to see how audio is synchtonized with video.

I have executed the test, and it is correct.

However with what Im doing unless I record sound at the time of recording, it will be hard to put back into the video.

Thanks for the quick reply

Hello Watkins577,

Thank you for your post. Could you please make a simple test?

Just start your system clock with minute/secund poiner, and recor it during two minutes without audio.

If there is any porblmem, the resulted video should be played back faster/slowerr than two minutes. Is it is so, please upload us such a clip to review.

Faster/slower video recording than sound

With videos Im making (Or trying to make) Im having problem with the AV, as the video can generally be slightly faster than normal, but it can also be slower, and as there is sound, you are easily able to tell when this is. Any ideas on how I can solve it?
