There are plenty of real applications for inferring every frame of video. Any real time monitoring application would run all the frames, even if you cut it to 1 FPS with multiple video sources the monthly price doesn't make sense.
One application would be nudity detection for a family friendly site, lots of video would need to be checked.
The argument that you would want to run your own machine validates my point. However the same could have been said for video encoding or any other form of intense processing which all now have cloud alternatives.
OK. I don't think this is the solution you're after if your problem includes "crowd sourced video".
Nudity detection though - I'd probably at least try doing something like "Check every 50+rand(100) frames, and only examine more carefully if you get hits on that sampling". Sure - that's "game-able" - but subliminal nudity isn't something I'd expect trolls or griefers to expend too much effort to slide past your filters...
