Premiere CC 2015 and DVD conversion audio sync issue Years ago, I transferred a video tape of a live band performance to DVD (using a Sony VHS/DVD RW machine that I no longer own). Yesterday, I edited an 8-minute clip from the DVD. The audio/video sync appeared fine inside Premiere, but when I exported to YouTube, the audio and video are completely out of sync.

(I didn't touch the alignment of either audio or video tracks while editing)

All I did was add titles to the beginning and end.

How can I prevent this from happening in the future?
Make sure your video has the same fps as the original video, usually it's 25/29fps. It could also be the format that you're exporting it to.
