I'm trying to understand what you wrote. It's very interesting. But I can't parse what you mean by "Shot length = tiny person". Did you mean short length? Are you saying that the focal length is directly proportional to the physical size of the viewer and that a wide focal length is in proportion with a tiny viewer and a telephoto is in proportion with a larger viewer? And thus Hitchcock's affinity for 50mm was so that his lens choice was always in proportion with the actual physical size of his audience? What would he do for establishing shots?

Greetings, One of the hardest concepts I've grappled with in understanding digital cinematography is motion cadence. As best I've understood, some cameras render motion in a superior and/or more cinematic manner than others. Is there any objective way to discern this? This may in part (or whole?) be due to the codec (e.g., All-I versus Long-GOP) and may be in part due to other reasons (processing of the image off of the sensor?) or other factors that I'm not considering. Then there is perhaps a separate issue (or is related to the motion cadence?) where some panning looks horrible due to stutter or jutter or some other term? And then there's flickering and strobing related to artificial lights and frame rates? Watching stutter hurts my eyes to watch. It's like there is some kind digital artifact leaving a resonance or afterimage in the image and looks unnatural and unpleasant. These are some examples of this: Maybe I'm not understanding the above video on how to avoid stutter as all the pans look like they stutter to me. I understand how shutter speed/angle can become a relevant variable in the equation, but if one is shooting at a 180 degree shutter angle shouldn't that solve the issue? And then to add more complexity, there is the question of the screen that you're playing back on, and its refresh rate. And many of the videos I'm watching are on YouTube -- so is you YouTube doing something to make the equation worse? But I've seen this on my own files from my own cameras. And I've tried watching videos on TVs or monitors or phones and I can still see that ugly stutter from some (too fast?) pans from digital video cameras. The practical reason I ask this question in part is due to pans I'm taking with various mirrorless cameras looking bad like the above videos. When I watch professionally produced video (I mean mostly Hollywood stuff here) I don't ever recall seeing this judder or stutter. Is their movement simply slow and stabilized enough to avoid this all together? Or does their cinema cameras mitigate this significantly? Or something else? And how much is it worth to chase good motion cadence and ALL-I codecs? Thanks for any guidance or information on this subject. -MC
