Foolishly allowed the latest patch update while halfway through a long project. Since then video feed showing as blank/black.

Successfully recreated the video feed (its made of still images) in the app and exported, only for those files to also show as blank/black when I added the finished vids to powerdirector.

I am assuming its just an oversight from me, I can still see/use still images, so what am I doing wrong? And no its not opacity or visually muting"
