Footage suddenly going black
I hope somebody might be able to help me.
Recently, when I've been exporting footage from Premiere, I've noticed that some scene's footage just isn't exported. The sound remains, but in the final file, the screen will just go black. Even sometimes when I'm viewing the timeline in Premiere itself, a clip that I've imported will just black out half way through ... and I don't know why.
I've rendered the timeline and tried using different export settings, but nothing seems to work.
I'd be really grateful for any help/advice.
