Hi there,

I'm kinda new to video editing, and I currently use Vegas Pro 21. I'm trying to make a video of different gopro clips with different frame rate (30-240FPS). When editing the clips with 30fps, I have no problems with preview, but when I edit the higher FPS videos, the preview is super laggy. I've changed the settings in the prosject from 30 to 60fps, but no difference.

What should I do to fix this? Also, the videos with 240fps is supposted to be played in slo-mo. What is the best way to do that? Currently i insert velosity, and drag it down. But I feel like there is a better way...

Any help is very appreciated :)
