I don't understand the timelapse and slo-mo use cases here. For 
small-scale factors, these seem like playback properties to me, not 
recording properties. In other words, the desired effect seems 
achievable by either speeding up playback or slowing it down.

For actual frame-skipping timelapse, a perfectly performant solution 
to me seems to be to render a frame into a canvas that's hooked up to 
a recorder with no framerate specified. This is defined to generate a 
new frame every time the canvas changes. If I do this at e.g. a 1 
second interval, then it'll throw away all other frames from the 
camera, producing a true timelapse recording without extraneous 
frames.
