Dynamic range is the difference between the lightest light and darkest dark which can be seen in your video. To create HDR Video the camera captures several identical images of a scene, each with a different exposure level which are blended together in post.
The most obvious benefit of HDR video is that you can shoot a scene that has vastly different exposure levels without over or under exposing different parts of the frame. So for example, if you are shooting outdoors – you keep your main subject exposed while protecting the highlights.
Secondly, HDR video is really, good for shooting transition scenes; so if you are shooting a scene that transitions from indoors to outdoors, you can edit the two frames together To keep your aperture, depth of field and exposure levels constant throughout the take.
You also get a lot more flexibility in post – and not just in the colour department. Because the shutter speed of the underexposed frame is shorter, you have an image with much less motion blur. This means you can pull higher-quality stills your editor will be able to do more solid motion tracks and keys.
Obviously, the ARRI and Red excel at this (You’re looking ARRI footage right now) – but you can also get a pretty good result from a DSLR running Magic Lantern.
