very early attempt to do some HDR tone-mapping on CineStyle footage. Sorry for yet-more-internet-cat-videos, but we're heading into winter here and I haven't had much time to shoot during daylight. I'm sure going between full sun and shade at ISO 160 would be a lot less noisy than this. And sorry, also, for the clips' many other shortcomings. Just wanted to get something out there.
What you're looking at is: my cat and kitchen shot at 1/50th, 50mm ƒ/1.8, ISO 640 on a 550D with Magic Lantern, going between about 14W of CFL light, thru shade and into 18W of brand new LED light. WB was set to tungsten, but obviously these "warm" fake lights were even yellower. Nothing relating to the exposure was adjusted while shooting (eg ISO, Exp or Aperture).
The HDR was produced by first making a TIFF sequence of the original footage (which I did at 10fps to save some rendering steps) and then running those thru the open-source "pfstools", using various trial-and-error values in the settings, and then recombining them back in FCP. Because FCP cant do nonstandard frame rates (and I forgot I'd done it in the first place) the whole thing is sped up about 2.4x so that the shots line up again.
Obvious issues are: the picture noise, the rapid changes from frame to frame (there are temporal-aware options in pfstools, but I haven't tried them yet) and obviously the pix look pretty unnatural. But I think all of those can probably be overcome and there might be a (limited) number of times you could use this for "slightly high dynamic range" video shooting.

Hmm…it looks like things are taking a while to load. Try again?
