That'd work nicely (combined the image processing algorithms were good enough) for regular stuff, but you'd need some complex trickery and/or cooperation from the manufacturers to ensure that when you wanted a filmic look, you could get it. I saw some TVs on demo in a shop recently, showing Transformers from BD - two TVs had 100Hz upsampling enabled, smoothing out the picture, and the other one was showing in 24p. These were all very expensive panels from the A Game manufacturers (no rubbish makes here!) I have to say, I wasn't pleased with the faux-100Hz look of the two panels that were smoothing and interpolating, I much preferred the film look. I know this was a film and nothing like live action / news broadcast, but we'll probably have to wait another tech generation for this kind of 'interpolate on/off' flag to be added to the spec of whatever broadcast format we're using then won't we? (though that said, although I <3 720p/1080p/4K cinema projections/whatever comes next, I only really like supersmooth video - like 50hz bob deinterlaced video - for things like motorsports and suchlike, for everything else I'm quite happy with frame judder. Audio quality is far more important for me... I'm a strange boy.) > Another thought I had was what about capturing motion > separately to the picture, at a lower spatial, but higher > temporal resolution.

That reminded me of what Radiohead did with their music vid for House Of Cards (with the spinning scanning lasers) :) (http://digg.com/hardware/New_Radiohead_Video_is_Shot_with_Lasers_Not_Camera s if you missed it) - Sent via the backstage.bbc.co.uk discussion group.
