Spotless Crake

Many video cameras are now capable of shooting in HDR and this leaves you with the question of how to process your clips. The 11 stops captured by the video camera (or 16 if you are using a good still one) are a problem when you come to present them on a 7 stop computer screen. Here I've processed the image for 7 stops and the sRGB profile, and dropped the clip from UHD (3840 pixels) to HD (1920). It looks a little "over ripe" perhaps, but I strongly suspect that as people get used to 11 stops of latitude and an extended colour range of modern televisions, this will age better than the alternatives.

The video is shot with manual settings, including the focus. The shutter speed used was one hundredth of a second. This is higher than I would like, but when hand holding a 700mm equivalent lens, you need to use active stablisation. Lower shutter speeds will tend to show up points of strong post processing movement correction as an overall blur. You'll see hints of that here. A tripod will cure these ills, but you often don't get a chance to set things up for the shot. Post processing was done using the free version of Da Vinci Resolve 14.2. My usual shutter speeds are usually double the frame rate being used, which is either 25 or 50 frames per second.

I've added a second clip which is 10 bit, instead of 8. This makes for a huge file, but gives you the chance to see if there's much difference on your screen.

Spotted in 10 bit colour.
