Question / Help Another Black Screen Problem

purebordem · Dec 15, 2013

Hi all,

Like many I am a newb here and am having black screen issues. However I am not trying to stream, instead I am outputting to an mp4. I can successfully preview my window and see movement without a problem. However when I view the output file in quicktime it just comes up black. However the sound does work. Any thoughts?

What exactly are you trying to stream? Does this happen if you view the file in another video player? For some reason right now quicktime is known to have some problems.

Oh, well now that you mentioned it...it works in WMP...odd. I was just recording Chrome as a test. Should I consider converting the file after saving it to ensure it works in other players?

I'm not entirely sure, I wish there was a way to figure out exactly what the problem is, but these programs tend to be vague about what they had issues with.
