miguelao has just created a new issue for 
https://github.com/w3c/mediacapture-record:

== Add a `MediaRecorderOption` to force a given source video frame 
rate ==
This would allow `conforming` by forcing the timestamps of the 
container to be generated at a certain frame rate, versus the normal 
way of following the wall clock which somehow resembles the real time 
production.  This would allow e.g. shooting at 120fps but forcing a 
recording at, say, 30fps, which will produce a slo-mo video at 4x 
speed.  I propose adding a parameter to 
[`MediaRecorderOptions`](https://w3c.github.io/mediacapture-record/MediaRecorder.html#mediarecorderoptions-section).

I like specifying the frame rate itself versus e.g. a 
multiplication/division factor so that it's not depending on the input
 frame rate, which might be flaky, e.g. with changes in illumination.
