Does anyone have the definitive answer now if legacy cameras, video, etc. is supported by Big Sur?
I can definitely tell you that you should not assume FireWire will work now or in the future. If you have any personal data that is dependent on FireWire equipment, you need to transfer all of that data to a modern format.
Do this now.
You can read more about the tragedy of Firewire here. Apple asked for a 25 cent license fee for FireWire and the rest of the industry just laughed and dropped it altogether. But when Apple uses technology from other companies, they are expected to pay billions.
I tried to use my old iSight FireWire camera years ago, on a 2011 computer that still had a FireWire port, and it didn't work at all. If your current FireWire equipment still works, the only thing you should use it for is to transfer your data to something else.
