Hi,


When I export a clip in "file" format it exports as .mov. But Quicktime won't play it. I can't figure out what's wrong. I am running Big Sur on a MacBook, everything is up to date. I have done this twice. The file is about 4.5 GB.

MacBook, macOS 11.1

You are obviously choosing "Best" quality to export your movie.


Do not use "Best".


Use either High, Medium or Low.


These will give you the best quality for viewing.


"Best" quality is very misleading. It is only intended to be used if you are making a masterfile of your movie to be re-edited at a later date.


It results in a file 10 times bigger than normal and should not be used for anything you want to view on a computer, TV, mobile or the internet.
