Slow motion, speed-ups and speed ramps
Ask Eddie to slow a shot down, speed it up, or ramp between speeds. It plays in the browser and bakes into your MP4 and NLE exports.
Eddie can change how fast a shot plays. A constant speed is plain slow motion or a plain speed-up. A ramp eases between speeds inside one shot — 100% up to 400% and back to 100%, for example — which is the move that gives a montage or an opening hook its lift.
Speed changes are available to everyone. You do not need to turn anything on, and there is no extra charge.
Ask for it in plain words
Point at the shot and say what you want:
- "Slow this shot to half speed."
- "Speed the walk-in up to 400%."
- "Ramp into this shot and back out again."
- "Put a 200% speed-up on the drone clips."
- "Take the slow motion off that one." — any speed change can be removed again.
You can also open an edit's timeline view, hover a clip and click the ✨ to scope the request to exactly that shot. See Refining clips with ✨ spark.
What it does to your timeline
A retimed shot keeps all of its content and changes length instead: a 10-second shot that averages 250% lasts 4 seconds. Everything after it moves with it — titles, captions, graphics, b-roll cutaways, voice-over and sound effects are all re-placed for you, so the cut stays in sync.
Speeds are limited to a quarter speed at the slowest and eight times at the fastest. Ask for something outside that and Eddie clamps it and tells you.
Speech is the one thing to watch
A retime mutes the shot's own audio, because sped-up or slowed-down words are unusable. Music, voice-over and sound effects keep playing normally.
The one exception is a gentle constant speed between 80% and 125%, which keeps the voice and corrects its pitch.
So Eddie will not ramp a shot somebody is talking in. If you ask, it explains why and offers the alternatives: ramp the b-roll instead, ramp across a pause between sentences, or use a gentle constant speed. If losing those words really is fine, say so and Eddie will go ahead.
Where it shows up
- In the browser player — press play and you see the retime immediately.
- In an MP4 export — the curve is rendered into the file.
- In an NLE export — Premiere, Final Cut and Resolve all receive the retime as a real speed change on the clip, not a flattened render.
Speed changes sit happily alongside motion (punch-ins and Ken Burns) and crops on the same shot. B-roll laid over a shot is not retimed with it.
