It reads the videographer's intention
It knows the difference between walking into position and actually shooting, and marks where the shot really begins. Choose how strict it should be: Smooth, Moderate, Action, or a threshold of your own.
Universal macOS app · Premiere Pro panel
Every take has a perfect few seconds. SmoothDetect finds them.
Point it at a folder of gimbal, handheld or drone footage. It goes through every clip, marks where the shot settles and turns silky, and hands back trimmed moments — real files, ready for whichever editor you cut in.
Runs entirely on your Mac. No cloud, no uploads, no AI. Your footage never leaves your drive.

the rest is the walk in and the walk out
How it works
Three passes, one folder in, a cut-ready bin out.
You already know which shots are good. The job is finding exactly where each one settles — and doing it across two hundred clips without watching them all.
Moments, not whole takes
Each clip gets in and out points around its usable window. Copy-trim losslessly, or encode ProRes for a heavier grade. Nothing is re-rendered that doesn't need to be.
Speed shaped to the move
Ease in, ease out, or through the middle — at slow, medium or fast pace, optionally locked to your track's tempo. Render them for the whole batch as it ingests, or one clip at a time. Rendered, not keyframed, so the timeline stays light.
The app
Batch the boring part.
Drop in a shoot folder and walk away. SmoothDetect works through every clip, shows you what it found, and lets you overrule it wherever your eye disagrees. It hands back trimmed files and XML — so it fits Resolve, Final Cut, Avid or Premiere without caring which one you opened.
A session you can actually read
Every clip in the batch, with its found window, duration and status. Scrub any moment before you commit to it.
- Live queue — analysed, rendered and remaining, at a glance
- Player with real handles — nudge in and out, see the frame
- Reject a clip and it stays out of everything downstream
- Reopen a session and your results are still there
Ease InEase OutMiddleIn+Out
Ramp the whole shoot, or one shot
Ramps come out as rendered files with real motion — no keyframe soup in your sequence, and no plugin dependency for whoever opens the project after you. Three ways to make them, depending on how sure you are.
- As it ingests — select one clip or the whole batch and the ramps render while the footage comes in. Walk away, come back to shaped shots.
- Per clip, in the app — every moment in the list carries its own ramp buttons. Working in XML-only or trim-only? The buttons are still there; ramp the three shots that need it and leave the rest alone.
- Per clip, in Premiere — ramp whatever's selected on the timeline, in place, from the panel.
- In · Out · Mid · In+Out at slow, medium or fast pace — or locked to your track's tempo
The Premiere panel
SmoothDetect Link lives where you cut.
Three tabs inside Premiere Pro. Bring the moments in, render ramps against what's on the timeline, and fix the things that normally cost you an afternoon.
Import
Included- Moments land as trimmed subclips with thumbnails
- A string-out sequence, built in order, ready to shape
- Drag any moment out and it keeps its trim
Ramps
Included- Ramp the clip you've got selected, in place
- Renders only what this cut needs — not every variant
- Reverse a shot without losing its trim
Tools
Studio- Twelve tools for reworking a cut that already exists
- Every one leaves your edit points exactly where you put them
- One Revert button, and it walks the whole operation back
Cycle
Swap the shot in a slot for a different shot from the same footage. The cut keeps its timing — only the footage changes.
Shuffle
Redeal the shots across the clips you've selected. Same edit points, new order, music still lines up.
Swap
Trade the contents of two clips with each other. Useful when a shot is right but in the wrong beat.
Split+Fill
Halve a clip and fill the back half with a different shot. One long beat becomes two, without re-cutting.
Fill gap
Drop a fresh shot into the gap under the playhead, trimmed to fit it exactly.
Reject
Banish a shot you never want to see again. Cycle, Fill gap and Split+Fill stop offering it.
Reverse
Play a shot backwards without losing its trim — the moment stays the moment, running the other way.
Warp 3% · 50%
Stabilise what's selected, gentle or heavy, without opening the effect panel.
Warp All
Sweep the entire timeline, stabilising everything that isn't already done.
Re-analyse
Find clips whose stabilisation broke and repair them, keeping the settings you chose.
Fit
Make 4K on a 1080 timeline read a true 50% — the number every other plugin expects to see.
In 5% · Out 5%
Nudge scale in or out, five percent a click, for quick reframes.

Cycle
Click Cycle on the same clip again and again. A new moment each time, and the edit points stay where they are.
Shuffle
Select a run of clips and click Shuffle. The shots land in a new order; the edit points stay put.
Split+Fill
Select clips and click Split+Fill. Each one is cut in half and the back half becomes a different moment, with the timing unchanged.
Warp Stabilizer on twenty clips, in one click
Select the clips — twenty, fifty, the whole sequence — and click once. Every one that doesn’t already have Warp Stabilizer gets it, and they analyse in a queue while you keep cutting. And when Warp breaks quietly later — a clip extended past its analysis, a reversed clip it refuses — SmoothDetect finds those clips and repairs them, keeping your settings.
- Pick the strength — Warp 50%, a gentle Warp 3%, or Warp 100% PSR (position, scale, rotation at full smoothness) for travelling shots you’ll speed-ramp
- Warp All — every clip on the timeline without Warp gets it, queued in waves
- Re-analyse — finds the broken instances itself and re-runs them in place, settings kept
- Fixes the reversed-clip refusal automatically, and steps smoothness down when a shot is too wild

Benchmarked on a real shoot, not a synthetic test. Times are for 100 clips averaging 10 seconds of 4K 50p — about 17 minutes of footage. Timed rows come from real runs of the same 174-clip, 32 GB shoot, normalised to that job; the others are projected from chip architecture. Everything extrapolates: 350 clips is 3.5× the time, 20-second clips double it, and the real unit underneath is frames — the engine works through roughly 26 4K frames a second on the base M1 and 63 on the M4 Max, so 25p footage runs close to twice as fast as 50p, and 1080p sources are faster again — the table is the heavy case.
| Machine | 100 clips · 10 sec average | Ramp rendering | |
|---|---|---|---|
| Mac mini M1 · 16 GB | ~32 min | Slower — software encode | Timed |
| Base M2 / M3 / M4 | ~25 min | Fast — ProRes hardware | Projected |
| M1–M4 Pro / Max | ~15–20 min | Fast — ProRes hardware | Projected |
| Mac Studio M4 Max · 36 GB | ~13 min | Fast — ProRes hardware | Timed |
Needs macOS 13 or later on Apple silicon. 16 GB of RAM is genuinely enough — the base-M1 benchmark never ran out of memory, and the machine stayed usable the whole time (we watched YouTube on it while it worked). Times assume footage on an internal or fast SSD, analysis and XML output; ramp rendering adds time on top when you use it. Windows is on the roadmap.
Stop scrubbing for the good bit.
