Bug description 🐛

Manual frame extraction is very slow. Loading the selected frame or extracting it takes about 30 seconds per frame. Automatic frame extraction is running normally. I have tried both .avi and .mp4 formats, both at the same slow speed.
My videos are 640*512, 80 frames/second. The video length is between 1 and 2 hours. The video size is around 4GB.
I previously used versions 2.1.5.2 and 2.3.4. There was not this issue.
