I was working in shotcut on a video but now the video layers don’t show. It only shows one with a black background. This is a sudden change happening late into video production.
Check the Timeline. Maybe you enabled the Hide feature on one of the tracks.
Sorry but I’m well familiar, and as you can see they’re on, but the background layers are not showing up.
I took a few examples to show it’s not just the one file.
Are you using filters?
I did attempt to duplicate the same issue with the information given.
Using Shotcut version 24.11.17, Windows 10
Video Mode HD 1080, 30FPS
No filters were used.
Click V2 to select the track and then view Properties to ensure that Blend mode is set to Over. If that did not fix it, then as @Hudson555x suggests, select the clip on V2 and view Filters and attach a screenshot.
