I use OSX with the built-in Screenrecorder from Quicktime.
It allows you selecting a screen region of arbitrary size.
The recorded several clips and want to edit them in Shotcut
for a tutorial, however it is impossible to import some clips.
the error is reproducible.
below are screenshots showing the files and dimensions.
green marked clips import, red cause Shotcut to crash immediately.
I also joined a red marked file.
I used OSX 10.13.4
SC 18.03.06
I trimmed the movie to about 3 seconds. this clip crashes as well when dragged in the playlist
