CANON MARK 5D II VIDEO 1080P
Here’s how they all compare to the full frame 1080p raw output…Īs you can see, the continuously shooting 2560 x 960 mode gives you a nice step up in resolution from 1080p, and will give you a narrower field of view from your fast prime without opting for a slower telephoto lens. This being a 1:1 crop of a photographic sensor, the results are about the same as a 1:1 crop of a 22MP raw still, so the quality is pretty incredible considering it is raw video we’re talking about here not stills. In the test at Slashcam we tested all the horizontal resolutions from 3.5K down to 1.92K and compared to the 1D C and the 5D Mark III’s own full frame 1920×1080 raw video. The resolution is 2560 x 960 and that’s continuous at 98.3MB/s on my 64GB KomputerBay 1000x card. The 2.66:1 anamorphic style aspect ratio I chose gives a Micro Four Thirds style sensor crop, actually a bit closer to the 2.3x crop of the Blackmagic Cinema Camera. At this resolution the camera only manages around 2 seconds before the buffer fills up but I can record for sustained periods of time by dropping this from 3.5K to 2.5K. It is a narrow aspect ratio but has a Super 35mm wide window on the sensor. The image buffer which supplies this view, is 3584 x 1320 in size.
It also has a sensor windowing mode, which Canon uses to show the very crisp 5x magnified focus assist. The 5D Mark III has a 5760 x 3240 full frame sensor. Further optimisations to the buffer handling by Alex at Magic Lantern aims to make higher resolutions such as 2560 x 960 at 98MB/s sustainable for longer or even continuous. Slashcam and I set out to test the 5D Mark III’s crop mode as precisely as possible using a chart – it is possible thanks to 100% accurate framing in crop mode with the black & white Magic Lantern live-view preview mode. Crop mode is covered in my 106 page EOSHD 5D Mark III Raw Shooter’s Guide on 5D Mark III raw video hereĪbove – EOSHD “raw rig” above is comprised of the Lanparte BMCC cage with 5D Mark III and LanParte follow focus / carbon matte box from HDVideoShop
