Storyline can't trim embedded video from PowerPoint import
I have a large PowerPoint that I want to edit in Storyline to produce a presentation I can embed on a web page. Each slide has video of the presenter, and some have a second video b-roll background. I want to trim the video of the presenter. Every time I try to simply trim a video using the Video Edit tool, Storyline chokes. The trim seems fine, but when I Save and Close, it only takes about 2 seconds to render, and the result is something like 1 frame every 3 or so seconds. Looks the same in Preview. When I upload to Review, it's even worse! The video and audio in it don't show up at all! I tried just importing 1 slide and doing the same thing, with the same result. Happens on more than 1 slide. (the PowerPoint plays perfectly, by the way)
If I save out each video from the PPt slide, trim it externally, then insert it, it works fine (NOT a good workaround for 48 slides, 55 videos!). If I then try to trim that newly inserted video, it chokes again.
