I have two YouTube channels. How can I control which channel Premiere uploads to? There seems to be no way to specify the channel.
Your best off outputting your videos as 1920x1080 mp4s and manually uploading them through your browser.
I don't know of a way to change accounts when you upload directly from the program.
The exact same process is used to create an MP4 and to create and MP4 and load it directly from the program, so I don't know how that could be.
What media player are you playing your MP4 with? Windows Media Player may not be the best choice. I recommend downloading the excellent VLC Media Player and seeing if it plays the audio out of sync.
I know of absolutely no reason you're getting such contradictory results, Patrick.
