It looks like Magic Lantern has done it again, this time proving that they can get 4K video recording onto the Canon EOS 5D Mark III.
What started as an April Fool’s joke has actually turned out to be reality.
Planet5D says of the development:
Now, please realize, much of this isn’t like full 4k with choose what ever you want fps, bit rate etc, some is pretty limited and you even have to put up with B&W previews. Here’s a comment from Alex for example “Only the simplest crop mode (1920×1080) h
as good real-time preview. The modes with higher vertical resolutions have color preview too, but it’s not centered (only the top of the frame is shown). In the regular crop_rec branch, there’s also centered 5x zoom. Here I’ve removed it temporarily, as it increased the code complexity quite a bit, but I’ll probably add it later when things will settle.”
On the 5D Mark III, you now have the following new resolutions:
* 1920×960 @ 50p (both 1:1 crop and full-frame – 3×3 pixel binning)
* 1920×800 @ 60p (same as above)
* 1920×1080 @ 45p and 48p (3×3 binning)
* 1920×1920 @ 24p (1:1 square crop)
* 3072×1920 @ 24p (1:1 crop)
* 3840×1600 @ 24p (1:1 crop)
* 4096×2560 @ 12.5p (1:1 crop)
* 4096×1440 @ 25p (1:1 crop)
* Full-resolution LiveView: 5796×3870 at 7.4 fps (128ms rolling shutter).
The last feature complements the well-known full-resolution silent pictures – the new implementation will be usable at fast shutter speeds, without the exposure gradient – but with rolling shutter (just like regular LiveView frames).
