I'm asking here as a last resort and I've exhausted every other resource I have access to right now and I'm agitated. I just want to up load a video to YouTube. A video that is audio playing over an image. I made the video in iMovie on my laptop, but iMovie isn't allowing me to do anything with it. I keep trying to share it to different folders, but when I click save nothing happens. I keep trying to update it but the app store has been buffering for like half and hour now. YouTube editor won't let me use my own audio. I don't know ow what to do, I'm ready to just give up unless someone here actually knows how to help. This shouldn't be this hard.
