This video will answer your questions about which model MacBook Pro to buy for video editing
M1 PRO or M1 MAX.

or should you wait for the 2022 iMac or MacPro?

I also compare the new MacBook Pros against the first version M1 MacBook Pro and the 24” iMac, suggesting who should consider those for video work.

The new M1 PRO/MAX models redefine on-the-go Video editing, In performance, battery life, screen display, and portability. But, are they the only choice for video editors or will the 13” M1 MacBook Pro or 24” iMac fill your needs?
