The third and final episode of Zacuto's film/DSLR comparison is live

Zacuto's Great Camera Shootout 2010 has featured a number of helpful comparisons between film and DSLR footage, and the third and final episode is now online.

DSLRs held up very well in the previous videos, but in this test Zacuto shows blow-ups, and it's interesting to see how well film holds up to magnification -- and how quickly video falls apart. Viewed at 100%, however, DSLRs once again compare favorably to film given the price discrepancy. I wish they would've made the video embeddable or available as a Quicktime download (it's hard to spot subtle differences in Flash-compressed video), but click on over to Zacuto for the third and final episode.

Awesome find. The testings were very interesting. Am I right, or did they say that using Prores or Cineform upconverts the color sampling to give a better color dynamic?

They did. I agree that transcoding to a better format allows for better post-production (color-correction, greenscreening, etc)., but I also suspect one of the reasons they're seeing such drastically better images is a gamma shift bug in Quicktime. More about this here:

Now, I thought Apple fixed this with a QT update, but then Quicktime X came out and mucked things up again, I think. Anyone else know about the current status of gamma shift in Quicktime?
