listen what you have to do, is when youre in powerproducer you put all your shit into the timeline or whatever and do your editing thing however you want
then you have to press produce at the top,
youre gonna wanna click create a file, not do the streaming to the internet thing
then you're gonna want either DivX(if you have that option, after a few days it popped up for me) or Mpeg2)
once it's done producing you should have that file in a folder in C: called my works, you can name it or whatever before you press start rendering (that little green check) by pressing the little ... to the left (its basically the only clickable thing)
then just choose the file when youre gonna upload and bam
but yea try that out tell me how it works
