I wanted to know how HDR would be useful for fast movement as I want to look into cameras that will move through regions of bright light and shadows and so, I want to see how I can make the footage more clear rather than get bland too bright and too dark components largely in the video. I want to check how action cameras implement such huge dynamic ranges. I'm a beginner and am slowly learning, so I might not have understood this right, but please help
There is rarely a direct relationship between HDR, or dynamic range in general, and motion artifacts. There may be an indirect relationship when trade offs are made for transmitting or storing the increased dynamic range. A specific implementation might reduce the frame rate or increase the compression in ways that introduce motion artifacts.
