Dear all,

Issue:

Some sound tracks in my video are "jerky" / "halting" / "jolting" once the video is exported.

Full description:
-The audio files are independent from the video

-Video files are muted

-Some audio files works, some don't (there no obvious reason for that, all audio files are more or less the same)

-The files perfectly well when playing the video in WMM but as soon as I export the video and play it on Windows media player for example, it does the -same jerky sound.

Failing attempt to solve the issue:

-I restarted the software

-I restarted my computer

-I exported the video in several format

-I played the video on several software

-WORST: I deleted the audio track and imported the same one / another one 

Nothing changes. My problem remain the same. It's like it comes from the video track but I don't understand why.

If you have a suggestion please do not hesitate.
Thanks,
David
