Strange! Does this happen every time or just this once?
Do you definitely have stuff recorded that should be showing up instead of black?
And there's definitely nothing other than your puppet in the scene, no extra backgrounds or anything?
Seems like a weird error, I've never seen this myself or in the forums before...
I realized the frame rate changed from 24 to 12 when exported. The problem was solved by switching it back to 24 fps. Hehe thank you Samurai!
