Some crop presets could include portrait of landscape to fit on a smartphone screen, for example.

Please do this or was it done and I missed it?

Cant over state how much blur and crop would add value - and speed editing for when there is something you want to remove

Yes! Please do this. It would enable creating split-screen moments of seeing both guests talk on screen, rather than make it necessary to export out to Premiere to crop each video so we can fit as much of guest + host possible (each as a square video) within the rectangular frame

A blur mask might help as well... esp. for teaching if there is something that you notice a small part of the screen that shouldn't be shared.. / viewed..

This is more important than it seems. The amount of projects I have to export out to Premiere in order to finalize things would be cut in half if this were implemented. It really should have been introduced when you created the ability to resize things.

Make sure they can be cropped inside of sequences too!

So I could crop out the left 2 inches of a video frame, then apply it to the entire 20 minute video if I wanted to? That would be cool if so.
