Seems something went wrong when the video was compiling, if you still have the original project you could re-compile the video and re-upload it. This has happened to me before and is why I watch every video I finish compiling.
No, it's the video...Damn, something must've happened between the edit and the upload because the source video looks just fine on my end. I would say I'll re-record this but to me these videos are better when they're done blind so...Hopefully the next one doesn't have this issue...
