Speed range: 0.8× to 4×. Interpolation: linear.

Anything where the process is boring but the beats are not
Shape
Linear interpolation so every transition is a step, not an ease. Real time for the first 2%, 4× for the bulk, a beat of 0.8× dead centre, then 4× again and a real-time tail.
Why it works
Viewers forgive fast-forward when it is obviously fast-forward. The instant snap into 4× reads as a stylistic choice; a slow acceleration into it reads as a mistake.
How to shoot for it
Frame rate barely matters — nothing here is slower than 0.8×. Stabilise the camera: 4× amplifies every wobble by four.

Tips
Lock this to beat markers (Beat Sync → "Peak on beat") and the snaps land on the music.
Motion blur "cinematic" hides the frame-skipping in the 4× sections.
Swap the middle 0.8× beat for 0.3× if there is one moment worth lingering on.
FAQ
Why not just cut the clip in an editor?
You can. This is for the case where you want the continuity of one shot — the same take, compressed — rather than several cuts.
