I can not finish an edited video to completion. I had no problem last weekend or prior projects. Video length is no different than what I normally edit. HELP

This is the message I get over and over.

I suggest you make the video editing on a pc you ll get better results

Sorry, I never used DJI Go for editing.
My PC is much better at performing that job (also at higher resolutions etc.)
But there are some others with this issue.

What is the resolution of your original footage?
It must be 1080P or below.
