Alternates 3× and 0.5× on a 20% period — two slow dips at 20% and 60% — and finishes at 2× so the clip hands off to the next one with momentum.
Why it works
A montage needs pace and it needs punctuation. The 3× stretches are pace; the two 0.5× dips are where the viewer is allowed to see a face, a landing, a plate.
How to shoot for it
60 fps is enough; 0.5× from 60 fps is a clean 30 fps. Any lower and the dips look like stutter rather than slow motion.

Tips
Line the two dips up with the two strongest frames in the clip before you touch anything else.
Apply to several clips in Batch and export them all with one curve for a consistent rhythm across the whole edit.
Beat Sync → "Dip on beat" produces this shape automatically from the track's beat grid.
FAQ
Can I add a third dip?
Yes — drag a new point in at 0.5× around the 40% mark. Three dips work on clips over 12 seconds; on shorter clips they crowd.
