Shotcut crash when appling filter on source tab

Hi all,

I’m experiencing a crash of Shotcut, when I apply a filter to the source window.
I don’t know if it realy make sense to apply the filter there, I found this issue during testing and finding a pattern according to this issue.

Because it’s better to let pictures (or better pictures in motion) speek, I recorded some videos. As you can see between video 1 and 3, the issue doesn’t occure everytime exactly at the same stage, but latest, when you change between “Source” and “Project” Shotcut crashes.

Some more information:

Again I cannot repeat the problems you seem to be experiencing.
I tried all of the above and got no crash.

Maybe uninstall Shotcut, then reinstall it selecting to delete the registry settings.
Or maybe you have some other software conflicting.

Also, does your computer’s region settings use a comma delimiter decimal symbol? This is known to cause some problems with certain functions.

I just did a complete reinstall (with removing registry) two weeks ago, but I’ll do it again…
About the comma separator, I guess we have this, but I need to double check and report back.
Thank you for your help so far!
I’ll keep posted…

I just tested this on my working computer and I got exactly the same issue:

On my working computer I have Shotcut 18.05.03.
Here’s a screenshot of my location settings from my working computer (sorry for german again).

I assume, that I’ll have the same settings on my home computer, but I’ll double check that.

In Switzerland (where I live and that’s my location setting as well) we use “.” as decimal separater. Not like the Germans, as I know, they have “,”.

I just reinstalled Shotcut on my home computer with removing registry settings. I also cleaned C:\Users%username%\AppData\Local\Meltytech\Shotcut before.
Still the same issue.
Below a screenshot of my region settings on my home computer (same as my working computer).

I just tried to change my regions settings go english (US): still the same issue (even after a reboot).

What I also tried:

  • GPU Effects On/off
  • run Shotcut as administrator
  • DirectX
  • OpenGL
  • Disabled Anti-Virus real time scan
  • use only one Screen on my computer (instead of two)
    still the same…

Any suggestions what I could check next?
Change my computers language to english?

Could please some other people in this forum try to reproduce the issue, it’s only 1 minute to test… would be highly appreciated.

Best regards,


Edit: I just recorded the last steps before Shotcut crashes with Process Monitor, not sure if it helps…

Aside from having [Australian English] Windows 10 Pro 1803 installed and 20Gb RAM - there’s no real difference with our PCs.
I can’t repeat the error here.

Maybe the devs can help fathom it.

Did you try to put the program on Eng - US to see if it’s the same?

While the above didn’t cause a crash - I have experienced a likely related crash.

See here ► [Bug] See body text

I only us Shotcut with English language, but I just tried to switch to german: Same same, at least after dragging the source to the timeline and then switching between Source and Project back and forth Shotcut will crashed… (as usual).

I reproduced this bug on both Windows and Linux, and I am working to debug it now.

Thank you very much, it’s highly appreciated!

This is fixed for next release v18.08. It was a regression since v18.05 with introduction of keyframes. Thank you for the good report. I was noticing a general instability that was being a bit difficult to pinpoint, and this helped a lot.

Really looking forward to 18.08!
Is the cause of this bug somehow also related to the following issue?
