No, but the burden of videography is a lot higher than the burden of writing a paper. In fact, a paper isn't written for every study, so in order to write a paper, you'd have to take video of every study just in case one of them is used in a paper in the future. It's a much higher burden than people want to believe. Add to that the fact that most animal facilities won't add cameras unless you force them at gunpoint because historically, videos of that sort make for targeting by protest groups.
Sure, but a lot of information does appear. Not everything appears in papers; should we stop publishing them?
