+1 no videos. Gifs yes. Screenshots and text descriptions yes. No videos:

A video can't be searched, it can't be scanned, and it can't be watched without headphones on in many settings.

I recognize lots of people learn by video or research by video, though I feel like a person watching a video has to have a level of commitment to your product that's higher than a person scanning for screenshots. Video should be "level 2"
