Hello,

I'm new with Lightworks, so I'm hoping this is a quick and easy fix. The audio lags behind the video. I am viewing and listening through the left preview screen. I've tried importing clips into a project under the settings of Auto, 60 fps, and mixed fps (3 separate projects, same clips) but I haven't found a solution doing that. I've read around the forums and saw that there can be a problem with variable frame rates. I've downloaded MediaInfo and it looks like I only have Constant on my video clips, no variable frame rate clips.

Here is the metadata from MediaInfo. Not that it matters, but I don't know why it says the language is Japanese... maybe because it's an Olympus camera.

Note: I see that there are some sort of LVIX files where my clips are saved in my hard drive. Are these copies of the original files that Lightworks then uses as a compressed or reformatted preview? Could closing Lightworks and then deleting these files possibly help re-sync? I don't want to goof up the project or the program by doing this.

Thank you!

Welcome to the forum.

The lvix files enable Lightworks to find your clips. Please could you provide the specification of your computer/
