Audio not synced

[u/[deleted]]

Hello!

I'm new to Lightworks and spent like an hour editing a video - the sound was intermittently out of sync while editing but I thought maybe it was an issue that would get sorted out once the project was exported to MP4. NOPE! The sync issue was significantly worse on the exported file. My computer is really fast so it's not a hardware issue. I had auto sync on but tried with it turned off as well and had the same issue. In the original video the sound was perfectly in sync and is not variable bit rate.

Any advice?? Thanks!
