When I add a .PNG file to use as a watermark or end credit, I see the word “Overwrite” in the video track I want to use and then Shotcut stops working and I get “not responding”
Actual steps:
I first add V1 track and drag my video track. Then I add V2 and drag the .PNG file onto it. I see the word OVERWRITE and then program stops.
Sorry I could not reproduce it using your fairly good steps. I do not know what is going wrong. Maybe someday someone else who knows how to code for Shotcut will experience the bug and contribute a fix.
