Sorry, a mistake (not enough cut)
- click on the scissors, 2 yellows cursors appears, at left, under the black "time line"
- click on the "-" at bottom left to no zoom the video time
- move the right bottom cursor right to the right side you will have all the "time line" yellow and red
- move the left bottom cursor right to have time beginning to 00:01:0x
- click on the right 3 dots, you will have a submenu and click on "Save clip as recording"
Now in "recordings", you have 2 recordings with the same title , the 2nd one with "Clip" under title
Try to export this one , the export red wheel should blink until the end of circle
Now try on the exported file "Open with" and "Others" and look for "TV"
I have tested on Intel and M1
