By “Video Card”, I mean GPU. GPU drivers are a common problem and cause of application freezing, etc. But you stated above that you tried both Nvidia GT 1030 and Intel i5 integrated 730 with the same results from both.
When I get the chance again I’ll try editing in Shotcut without ever leaving the window and see if it continues to work. I mean, even if the video is paused and I click on another program, come back, then replay, it still lags afterwards, which I think is pretty confusing haha.
Okay folks, so 1 week after my last message and… everything is working perfectly? Shotcut is playing 4K 30FPS videos effortlessly, when adding filters and such, I need to use 1080p preview scaling to ensure smooth playback, but that’s still more than expected performance. I’ve been trying to get it to lag, by switching windows, pausing and playing quickly, opening task manager in front of the Shotcut window, can’t get it to budge!
Shotcut, you have escaped my grasp this time… and well done. (?)
To be continued. Perhaps.
Well that’s good news. However, a little frustrating that we don’t know what fixed it. Hopefully it was a gremlin that was very specific to you and won’t affect anyone else. Happy editing!
Yes, thank you very much for your help and patience!
