What do you call non-fiction books and newspaper? They're people's memories transcribed. Some reporter watches the president do X and then wrote that down. That's recording.
Here's an example of a recording I made today in my head. I was on the way to work. I saw a blue chevy license #E17HV2 cut me off and then proceed to go down the freeway at around 80mph. A police officer was near by and sped after him. A few minutes later I saw he'd been pulled over by the cop."
That recording was in my brain. I just shared with with you. The guy speeding has no right to tell me I can't remember it. He has no right to tell me I can't share it (which I just did).
Video is the same thing just higher fidelity. Augmented me with digital eyes and digital memory is still me, same memories, same rights.
