Not sure if the 1DC goes in this forum or in the EOS cinema, but anyway.
I just tested the 1DC and I was surprised to discover a S35mm crop mode that I had previously not read anything about.
As we all know the camera has a 4K 4:2:0 mode and the same full frame 1080p crappy video mode that the 1DX has, which is kind of similar as the 5Dmk3. Not much aliasing but very soft in resolution. And it has some strange interpolation algorithm. In any case, no one will buy this camera to shoot in this mode, since the 1Dx does the same exact thing for half the price.
The 4K mode is quite sharp, it didn't show any aliasing and while only 8bits (too bad) it becomes a 444 signal once resampled to 1080p, which isn't bad right?
Now, there's another mode called S35mm 1080p crop mode which basically does what the name says. It crops the sensor to s35mm equivalent and records at 1080p. I was expecting even crappier results than with the full frame 1080p mode (similar to what happens on the nikon d800) but to my surprise, it renderS beautiful sharp 1920x1080 footage, with no aliasing and perfect resolution.
Here's a quick comparison.
Now this is great news because the 4K mode not only requires super fast CF cards but also fills them up so quickly that it's almost impractical for the main purpouse of this camera --> gerilla style docs. If my math are not wrong, 1 minute takes 4GB, a 16GB card will only take 4 minutes of footage. Imagine how many x1000 CF cards you'll need to be able to record an hour of footage... Not very practical.
Now with the S35mm crop mode, we'll still have good resolution and no aliasing, but this mode records in the same format as the full frame mode (1080p mp4 420 all-I) which still looks pretty decent, and which only downside is being 420. But we no longer need super fast CF cards nor we are so limited in the amount of time we can shoot per card.
