I had a look at other similar posts, but the answer is not clear to me. I have a folder called LUT (linux user by the way) and I downloaded the 35 free lut zip file. extracted all the luts into that folder.
Opened shotcut, selected a video and loaded it into the timeline. Selected it, then filters then LUT (3D) I opened the dialogue to load a LUT, and immediately shotcut crashes… every time.
Is this a bug, or am I doing something wrong please. Version is 20:10:31 and OS is Linux Ubuntu 18.04 lts
It appears to be a bug in the Snap build of Shotcut since we upgraded the Qt library. If you run /snap/shotcut/current/Shotcut.app/shotcut
instead of using the launch icon or running the /snap/bin/shotcut it adds to your $PATH, then it works. I do not know why.
I would love to have understood your answer but I am not very experienced with command line usage. Could you explain in step form what you mean please? Thanks
I did the test in Ubuntu Studio 20.10.
The Snap version of Shotcut crashes when I try to load any LUT file into the corresponding filter (LUT 3D).
I tried Shotcut in Flatpack version and it worked fine.
In the screenshot Shotcut (flatpack) with a LUT filter (Arabica12.CUBE)
I figured out that it is crashing inside an optional Qt plugin (platformthemes/libqxdgdesktopportal.so). I removed that plugin in a test snap build, and the file open dialog for LUT is working now. Testing so far does not reveal any problem without it. As far as I can tell, this plugin simply helps an application find alternative icons when using Settings > Theme > System in Shotcut. That would mean a minor cosmetic difference, but fixing a crash is the more important option. So, this is fixed for the next version.
