Keynote - How do I change a placed video thumbnail from the default black to an image?
Hi, I’m working in keynote to produce a PPT document. One of my pages has a video that I want to play on clicking. When I place the video, a black area appears, how do I change this black thumbnail preview to a custom image thumbnail.
InDesign, Acrobat, PPT itself I believe (I don’t use it) all allow you to do this, but from intensive searching, Keynote doesn’t?
Does anyone have a solution to this? Thanks.
