Hi, I'm a longtime VEGAS user with a new issue. Currently running Vegas Pro 20 (build 411) on a Dell XPS 8490 with 32GB RAM and an NVIDIA GeForce 3060 Ti graphics card, supporting two 24" monitors (one for timeline, one for preview). I've been editing on this setup since 2021 without issues. But today I'm working with video files captured on a hard disk recorder at a corporate event, all files are 1080/59.94fps ProResLT. ProRes normally works great with Vegas, but in the timeline these files show occasional color bars with the text "LOSS OF VIDEO" appearing in place of thumbnail images. Trying to figure out if this is a file issue or a processing issue? I've already turned on/off GPU acceleration and tried increasing the Preview RAM without any effect. Has anyone seen this before?
