I'm putting together a PowerPoint 2007 presentation and need to include a video, which is animated vector graphics that I'm producing by making lots of PNG files and then using FFmpeg to compile them into a video.
So far I've tried .mp4 and .avi formats. The video in .mp4 looks much better than .avi, and both videos display properly, but the preview still frame that is shown before the video starts is messed up.
In .mp4 I just get a black frame, which sucks. In .avi, I get the first frame on initial display, but after the video completes, it shows a black frame.
Is there any way to get it to always display the first frame when the video is not being played?
