Are the clips themselves not in sync, or just after they have been uploaded?
How long are the clips?
Seems like it had some kind of issue when it had to re-encode the clip. How much of a desync are you seeing? Do you have the video uploaded to look at?
Hmm okay...very odd since it's not the usual desync that we see.
Can you send in a support ticket with client logs? Here is the best method to do that: LINK
