has Biden done a good job as president?

[Angrboda]

Nope and nope. 
A video is a series of photographs, taken and played at whatever shutter speed your equipment is. 
Any commentary, which one can turn off, listen to, or ignore is irrelevant. 

why do you argue, known or established fact? something that can be proven?

this video is 3 mins long watch it..




This video demonstrates everything you said about what makes a primary source a primary source is wrong. it does so at the 22 second mark. "Original documents that do not analyze or describe other facts or documents." once you put a commentary to a video it stops being a primary source, unless that commentary is coming from the video itself. once you chop together several different videos to make a news story. it then becomes a tertiary source. 

God you are a monumental fuckup. You can't even quote your own sources accurately. It does NOT say, "Original documents that do not analyze or describe other facts or documents."

Maybe you should watch your own fucking video.
