This one is a real shocker to me. When I export this video in After Effects it has the sound, and the file is not corrupt, but there is no video. It is just a black screen while the voiceover continues.
The real odd thing is it plays in quicktime although it is pixelated and choppy. When attempting to play it in WMP it simply says it is not a readable file. There is nothing weird or wrong about my export settings, or so it seems to me, to explain this.
