Hello i bought VP16 for making music videos in 4k. My issue is while preview for example 10 cut clips 1-2 seconds long it just jumping after 4-5 seconds and its not watchable at all... I tried every guide on yt but same result.

My pc spec is:


Geforce GTX 1080ti

Samsung SSD 970 EVO 1TB

See item C-1 here:


The mediainfo report will help forum users to see details of the source clips.

Likely, the problem is the Gopro footage is highly compressed h.264 or h.265 which is not easy to edit (that's why Gopro used to offer software to convert to cineform AVI files). You may need to transcode to a different format to get good a good editing experience on Vegas (or any other NLE.)

Are you not using proxies for those type of files?

GoPro is notorious for jumpy preview.
