Can you help me understand what the shutter angle slider is used for.

Shutter angle modulates motion blur. It's simulating a rotary disc shutter. A greater angle means the shutter is more open and has a longer exposure, thus a wider streak of motion blur.

I've attached an example. The composition is exported with Motion Blur set to 32 samples and Shutter angle set to 45º or 360º.

Here's one example of Save Frames to Movie (attached). It pairs an audio soundtrack that plays in real time with video frames that are produced slower than real time. (Insert your own audio file.)

If your composition is audio-reactive — the audio and video are not independent as above, but rather the audio affects the video — you could try the strategy here: save the audio analysis to a file, then read the file back into the composition that you export to movie.

I'll look at it again. I assume in using Export that I'll end up with two files: one with video only and the other with audio only?

The Save Frames/Images to Movie node produces a file containing video and optionally audio. File > Export > Movie produces a file containing video only. (You'd use one or the other, not both.)

@eenixon, you're correct that offline render (File > Export > Movie) does not support audio. Here's the feature request for adding audio.

Instead of Save Images to Movie, you could try Save Frames to Movie. Together with Make Video Frame and Make Audio Frame, this would allow you to put a timestamp on each frame.

@jstrecker commented on @pbourke's Discussion, “RTSP not working, ideas?

Your RTSP feed doesn't work in Vuo 1.2.8 but does work in our version under development, so it's likely the same problem as this bug report.

Confirmed — we are able to reproduce it. Oddly it happens on some computers and not others (same OS version), or maybe it's just plain inconsistent. Anyway, we'll have to figure that out.

Good idea about the recent items in the welcome screen. Duly noted.
