Auto Edit in StoryCut: key facts
- Short answer
- Upload a talking video. When the captions are ready, click Auto Edit: StoryCut cuts the pauses, adds sound effects and zooms on the key moments and composes background music, usually in a minute or two. Watch the result, undo or remove any part, then export.
- What it adds, in order
- 1. Cuts pauses longer than 0.5 s between words. 2. Places a sound effect on 4 to 8 key words. 3. Adds zooms on the key moments. Music is composed at the same time: an original instrumental track, lowered under your voice.
- What it doesn’t do
- No B-roll, no transitions, no filler-word or bad-take removal, no clean audio and no eye contact correction. It doesn’t change your caption style.
- Free preview
- Free and Starter accounts get 2 Auto Edit previews, on videos up to 90 seconds, to watch in the editor. Only previews that added something count. Exporting a video with these effects needs Pro, or you can remove them and export on your plan.
- Plan
- Unlimited on Pro ($14/mo billed yearly, $19/mo monthly) and Business, on videos up to 10 and 30 minutes.
The four things Auto Edit does
Cuts the silences
Every gap of more than 0.5 s between two words is cut, and the captions are re-timed. With an eye contact fix, the corrected video is cut too, so the fix is kept.
Adds sound effects
Picks 4 to 8 key words in your transcript and places a matching public-domain (CC0) sound on each one, timed to the word.
Zooms on key moments
Reads your transcript and pushes in on punchlines and key statements. Change each zoom’s intensity, length and style afterwards.
Composes music
Writes a music prompt from what you say and generates an original instrumental track with Suno, faded in and out and ducked under your voice.
Why it cuts the silences first
Sound effects and zooms are timed on the words in your captions. Cutting the pauses moves every later word earlier, so Auto Edit removes the silences first, then places the sound effects and zooms on the new timings. Music doesn’t depend on word timings, so it is composed at the same time as the rest.
Auto Edit also respects what you have already done. If your project already has sound effects, zooms or music, it keeps yours and skips that step. If you have corrected eye contact, it cuts the silences out of the corrected video too, so you keep the fix.
Editor
Keep, Undo or Remove Each Effect
When Auto Edit finishes, a summary lists what it added: how many pauses were cut and how many seconds that saved, how many sound effects and zooms, and the music track. Undo the cuts or remove the sound effects, zooms or music one by one, then fine-tune what is left in the AI tools, like any effect you add by hand.

How It Works
How to auto-edit a talking-head video

- 02

Click Auto Edit
At the top of the editor, or in the bottom bar on a phone, once the captions are ready. It usually takes a minute or two.

Review and export
Watch the result, remove what you don’t want, then export. On Free and Starter, export with Pro or remove the effects and export on your plan.

What Auto Edit is good for, and when to skip it
Auto Edit is built for one-take videos of a person talking to the camera: tips, explainers, coaching, founder updates, LinkedIn posts. Those are the videos where the pace, a few sounds, a few zooms and a music bed make most of the difference, and where doing them by hand is the most repetitive.
Skip it, or remove what it adds, when the pauses are part of the video (a demo, a reaction, a dramatic beat), when you need B-roll or transitions placed for you (Submagic and Captions add those), when your takes are full of “ums” (StoryCut doesn’t remove filler words), or when eye contact correction matters more than tight pacing on that video.
Nothing it does is final. Every cut, sound, zoom and track is an ordinary effect in your project, so you can keep the parts that work and drop the rest before you export.
