Hey Alan,
It appears that you're having a problem using AirDrop between your Mac and iPhone 13 Pro. When you try to AirDrop a video, you receive a message that it failed, and we're glad to provide assistance.
How to check the storage on your iPhone, iPad, and iPod touch - Apple Support -- Compare the size of the video file with the amount of storage you have available on your iPhone. If the video is larger than the amount of storage you have available, use the steps in this article to reclaim some of that storage space.
If you have plenty of storage space on your iPhone, see if restarting both devices allows the video to be transferred:
Restart your iPhone - Apple Support
Log out, sleep, wake, restart, or shut down your Mac - Apple Support
Let us know how that goes.
All the best.
