Is it a problem specific to this project, some, or all?

3

I have tried to make shotcut crash on both flatpak and AppImage version on Fedora Linux, I have tried 4 diffent project in both packages and I cant make it crash using Copy to Source and setting In and Out point. So I don’t look to be a generic problem on Linux.

I checked this with two projects and it crashes…

I’m wondering about one thing more. In all cases I wanted to narrow to very short time, ex. 10 sec only. Might it be somehow related? Or perhaps temporarily one arrow goes beyond the second one in the way which is not expected?

5

I did not reproduce it that way…

Or perhaps temporarily one arrow goes beyond the second one

…or that way.

I am going to remove Copy Timeline to Source for the next version because it was really only a workaround until export from a region marker became available.

6

Makers is a much better ways to export timeline ranges, than used Copy Timeline to source and setting In/Out points and export from source, so I see no need for it anymore

7

Ok, so if it’s going to be modified next version, let me return to that when next version is released. I will do then more testing and we will see… Otherwise spending time on testing of sth which is going to be modified is so so…
