Canon 5D Mark III raw video crop mode performance

Crop mode is covered in my 106 page EOSHD 5D Mark III Raw Shooter’s Guide on 5D Mark III raw video here

Above – EOSHD “raw rig” above is comprised of the Lanparte BMCC cage with 5D Mark III and LanParte follow focus / carbon matte box from HDVideoShop

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. 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.

Panasonic GH2 1:1 crop mode changes everything again


UPDATE 2: This will give you a visual idea of the extent of the crop – [url]http://www.twitvid.com/GHWFB

UPDATE 1: Vimeo does not display AVCHD .mts files in full resolution, reducing it to a very compressed 720p format. If you are a plus user, download the original file at Vimeo here (right click this link, save as). The image above is not representative of the resolution that is being delivered by the GH2’s crop mode. That is an actually 1:1 crop to 820px wide of a frame from the AVCHD but it is heavily compressed by my site’s content management system. So watching the AVCHD video file is HIGHLY recommended.

• True 1080p resolution for first time on a DSLR
• No moire
• No aliasing
• No scaling
• No binning
• No line skipping

With that, we introduce the GH2’s secret weapon – 1:1 crop mode…

Hold onto your super fast c-mount zooms – GH2 Sensor 1:1 Mode sneak peak

EOSHD.com reader RichST who picked up a Japanese GH2 this week (production retail model) has been showing me some useful shots demonstrating the look of different picture profiles on the GH2, including the new Teleconverter mode. Seemingly Panasonic listened, because this is a feature the community has long been dreaming of. No line skipping, no pixel binning, no scaling – just the ability to take an unscaled 1080p 1:1 crop of the centre of the sensor.
