I've been using photoshop to cut together little 30 second videos videos from footage that I take during shoots. Until today I've had no Issues. But now when I click the "render video" button, the dialog box comes up as usual and I click render. Once the video has finished rendering, when I play it back in quicktime all of the clips are still frames rather than video. I don't think I've accidentally changed some setting somewhere that would cause this. Here are the render settings that have worked for me before but not won't work at all.
