I'm not able to state a conclusive definition for "visual grammar", but I'd say camera settings have a quite relevant role on building it. Depth of field (aperture) is crucial for focusing on a subject; ISO may be used for obtaining a noisy image which can be used to say something (to look like an amateur, or a security camera, for instance); WB ...

Yeah that was actually the best opening ceremony ever...
Doing something like this yourself is a hefty task, but first, here's what you would need:
A software for tracking
A software for modeling / animating
(optionally something for compositing / color grading)
Luckily, Blender (which is free) can do all those things, but has quite a steep learning-curve. ...

Yes, it is possible. Such a concept is often called "render farm".
On the server side you could use tools like ffmpeg that can concatenate videos. To call it you could build a dedicated render service which works like a job management agent (think of sth. like Jenkins). The goal is to decouple the render jobs from whatever service/API your app ...

The original video is an old, interlaced format. At least, according to the line that says, "smpte170m/bt470bg/bt709." The SMPTE standard is available for purchase here, but you can tell from the summary that it's interlaced.
The second ffmpeg command is copying the format without re-encoding, or handling the interlacing, which isn’t supported on ...

Yes. For things like exposure time, EV, f-stops, video is just the same as still photographs. You just happen to be taking 24 or more of them per second.
The one difference in actually exposing a frame would be that still photography typically uses a mechanical shutter. (You can hear it k'thwap when you take a picture on many cameras.) But video uses an ...

The question is impossible to answer in a general way.
If a camera offers to record in RGB, it is likely using a completely different codec that could be better or worse. Very few cameras will actually record video in RGB, so if you see the option in a menu, it may be referring to something very particular about the color handling of video on that specific ...
