When Should You Use a Speed Ramp in AI Video?

What went wrong in our edit

On a football montage, we applied the same ramp to five mid-tempo shots: a kid juggling, a pro juggling, a close-up of a crowd, and two rabona kicks. The ramp played the first 30% of each shot at normal speed and the last 70% at double speed. The feedback was short: "looks a little weird."

We took the ramps off and played those shots at native speed. The cut got noticeably cleaner.

Why it happens

A speed ramp tells the viewer something important is happening. When the pace jumps on a shot without an obvious motion peak, the eye looks for the reason and doesn't find one. So the change feels arbitrary, and it reads as a dropped frame or a playback hiccup rather than a choice.

Ramps work when the visual peak and the pacing peak are the same moment. Fast-then-slow on a dribble that cuts past a defender worked for us. So did slow motion on a goal celebration. In both cases the movement itself gives a reason for the change.

AI clips make the problem worse in one way: generated motion is often smooth and even, with no natural peak. Ramp a steady AI shot and there's nothing for the ramp to hang on.

How to decide, shot by shot

1. Start every shot at normal speed. Dialogue, crowd, B-roll and static shots stay there.
2. Find your money beats (the moments that matter most). Look for the frame where the action peaks: the strike, the impact, the leap, the turn.
3. Ramp only those, and center the ramp on the peak. Speed into it or slow down through it, so the pace change lands with the movement.
4. Pick a direction that fits. Fast-then-slow sells a burst of skill. Pure slow motion sells a moment you want the viewer to sit in.
5. If you want a faster overall feel, speed up the whole cut evenly instead of ramping single shots. A flat speed-up comes across as pacing, and nobody reads it as an effect.
6. Watch the edit through without stopping. If a ramp makes you wonder what happened, take it out.

An example

A 30-second sports short has eight shots. Six are crowd reactions, warm-ups and a coach talking: leave them at normal speed. One shot shows a player cutting past a defender: speed up into the cut and slow through the moment he's clear. The last shot is the celebration: slow motion. That's two ramps, both on peaks, which is usually enough.

The same rule for drama

In a micro drama, the equivalent money beats are a slap, a fall, a door kicked in. An argument across a table usually isn't. Keep dialogue at real speed so performances and lip sync stay natural.

You assemble, trim and pace the cut in the editor, and you can watch a free animatic of the whole episode before paying for any video, which is a cheap way to find where the real action peaks are.
