I enjoy such videos, but find them problematic. I'd like to filter by bouncing-camera style vs no-bounce, or perhaps on degree of bounce. Avoiding-pan style vs slow pan vs pan vs swivel to interesting things. Interesting things can be fun, but... "fun, fun, fun, fun, zap ouch! - now I get to be queasy for an hour". So perhaps intra-video filtering, like automatic blackouts, or vr-like "given the current angular velocity, we'll gray out much of the display, narrowing the field of view to a smaller circle, to avoid sickness"? Can a plug-in see an embedded video to do optical flow? Perhaps a site already curating such videos might value-add some image analysis? Are there popular channels with moments problematic for some viewers, perhaps creating a persistent niche for a mediating middleman?
