Fowards/Backwards really struggles with high-quality videos

My main use-case of Shotcut is to cut recordings of video games to archive them as a video.
I’ve previously recorded old games with a good quality and skipping through them with the highest possible forwards/backwards speed was never an issue.

Now I’ve finally got myself a new GPU and now I’m able to record 1440p in the best in-game quality possible with CQP 17 via NVENC, but skipping through those recordings is a real struggle: anything above double forwards/backwards speed will get choppy as hell.

Lowering the preview scaling quality + interpolation did help to some degree, but not by much.

Is there anything else I can do to get faster skipping speeds, or is that the expected drawback of such high-quality videos?

Proxy Editing

Introduction Proxy editing is the process of creating and using low resolution videos and images in places of the original or optimized (Convert to Edit-friendly) files. This provides the advantage that your computer has less work to do in realtime while editing: decoding, scaling, and effects. This is, quite simply, because there are less pixels to compute. Then, when you are ready to export, it will use the original (or optimized) files for full quality. Performance is optimal when the pre…

Thanks, but after tinkering around some more I discovered a quirk/bug: anytime I drag a video unto the timeline skipping ahead in that particular video is choppy as hell, but if I just restart Shotcut then skipping in that video works just fine.

Edit: nevermind. Switching to proxy editing is definitely the way to go.
