What is your operating system?
What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
20.09.27. 64 bit. Portable tar.
Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
When I load clip from playlist to preview, it first plays ok, but when I start to cut it (mark teh start of required piece by pressing ‘i’), and then continue to play, my CPU usage skyrockets and playback starts to hang. This behavior started about 4-5 days ago, never had such issues before.
I could probably do something with settings to cause it (I tweaked something in hardware encoder without really knowing what I do, or may be it was after I started to have problems, I am not 100% sure), but I have installed new version since then and would expect all setting to reset (perhaps I am wrong here) as I use portable tar.
