I am using a version of Vegas 16, I have a desktop with windows 10 and an RX 580 GPU.
I am attempting to edit screen recorded footage (recorded with bandicam) and it seems vegas deletes every still frame causing major sync errors, this seems like an issue with a simple fix, but I've been trying a lot of things to no avail!
Bandicam captures variable frame rate, which is not compatible with Vegas Pro 16. Easiest is to convert to CFR in Handbrake or rewrap with ffmpeg. Use the forum search.
Our recommended settings for OBS capture are in this thread.
