I have a general question about how various Canon cameras use their sensors to capture video. I've picked up some vague ideas along the way as I've read forum messages, and I would like to fill in some gaps in my understanding.
Obviously various cameras are not going to use their whole sensors to capture video, since the sensor has a 3:2 (or maybe 4:3) width to height, and video is normally 16:9 these days (or maybe wider for some purposes).
I get the impression that different bodies might take different approaches to using available pixels to produce video. Perhaps some might use the full sensor width and scale down to 1080p. Some might even use just the central 1920 x 1080 pixels, or maybe cameras do something between those two extremes.
Is there an online guide somewhere that explains how different models approach this task? My interest would be primarily in Canon products, and of course specifically in the ones I use regularly for video now, the 6D2 and the G7X II. But of course a more general discussion, and even better, a comparison of different approaches would be interesting.
But even if you don't know anything comprehensive, some general clarification would be welcome.
