Audio desyncs when exported

I made a 25 minute compilation of 170 different clips, muted. The audio is 7 different songs. Two tracks are used. The clips are recorded with nintendo switch. the framerates vary from 29,8 to 30,4 fps, and they are variable. now when i export the video to the youtube preset, the audio desyncs. I saw some other topics but i dont know what to do. Can you please help me out?

@shotcut?

Audio sync problems are known to occur when editing with variable frame rate clips. Did you convert the clips using Shotcut’s “Convert” feature in the properties panel?

No, and I don’t know how to redo that. Does that fix it if I convert all my 170 clips to the same framerate?

I would expect converting variable frame rate clips to constant frame rate will fix your sync problem.

When you open a clip with variable frame rate, Shotcut tries to detect it - and if detected will prompt the user to convert it. Sometimes Shotcut fails to detect variable frame rate.

To start, pick a couple of clips that are known to have poor sync, and run the convert process from the clp properties panel:

@brian when i click on convert it lets me choose between three options using a movable bar. What do i do here?

Choose “Highest” if you can afford the space. The bar is jus a range of quality vs size. The left is smaller, but slightly lower quality (to be honest, most people can’t notice the difference - but you be the judge).
