I downloaded the trial version and it works great except for out-putting HD video which it won't do. I upload 1280x720 (H.264) video but when I go to share it with Youtube or my desktop my only option is 640x480, no hd.
I've tried this with various video and the same thing happens. Is this how the way the trial version works or am I doing something wrong.
I have iMovie for a long time and have no problem with out-putting HD?
It sounds like you're editing and / or exporting as Prores Proxy. That's great for editing on a slower system but is smaller in order to make it work smoothly. Try setting your output to the full res files
