user9254: 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?

user11164: 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.

user3908: Based on your comment feedback, and as I suspected, it looks as if the main audio has 'slipped under' the new title video. An easy way to avoid this is to marry the titles with a silent audio track.
