This was shot on a Canon 1DC at 4K and down-converted to an H.264 2048x1080 frame size for Vimeo. I have noticed that the sections with post-crop are significantly softer because of the lower resolution. I would not suggest cropping very much on footage even if it is shot at 4k and the deliverables are in 2k.
All in all I was impressed with the image quality but the post-production is a pain in the ass for this camera. I would definitely go with a Scarlet with the 1DCs price point as of May 2014.
