When using OFS to open 4K or higher-definition videos, there will be a lot of lag and it is difficult to modify the funscript. Is there any good solution?

These lags make it almost impossible for me to view and modify the funscript by comparing the video

Yes! Either try enabling or disabling “force hardware decoding”.
Find it under → Options → Preferences → Player → Force hardware decoding

create i-frame version of the video file using funexpander. It’s a MUST for accurate scripting.

Or even better, use IFramer by CertainlyWicked with GPU support to create i-frame versions of your videos:

Turning this option on and off didn’t make it any better, but thanks for the answer anyway

I’ll give it a try, hopefully creating the i-frame version won’t be too slow
