RAW formats on digital cameras are also storing data in a log format. RAW conversion process is normally converting that to a color space along with (for most cameras) doing the De-Bayer algorithm.
The built in converter that produces JPG files in the camera does this too.
Our eyes perceive light as linear when it's really logarithmic.
There is really no difference between video and still here, it's just that it's more normalized at the consumer level to deal with RAW formats at this point for stills.

Fun trick: convert ProRes RAW to cDNG. You now have 59.94 raw DNGs per second to choose a photo from.
