Footage in, cut out
An agent cuts your footage, you watch the result
You bring real clips into the video folder. Whisper transcribes them, the editor agent picks cuts from the words and writes edit.edl.json, and ffmpeg renders the cut, plus the grade and the subtitles the EDL asks for.
- takes/The clips you shot, filenames unchanged
- transcripts/Whisper word timestamps, cached as JSON
- takes_packed.mdPhrases, split on any silence of 0.5 seconds or longer
- edit.edl.jsonSources, in and out points, grade, subtitles
- slug.mp4The finished cut, subtitles burned last
The build order, the 0.5-second silence the packer splits phrases on, and the fields an EDL holds are all read from the app's edited video pipeline.
What it actually does
Kamply is a Mac desktop app. You bring the clips: they sit in the video's own takes/ folder, keeping the filenames they came with, and the EDL names each one by id and path. Whisper transcribes them, and the transcript is packed into phrases that break on any silence of half a second or longer. The editor agent picks its cuts from that packed file and writes edit.edl.json. ffmpeg then does the assembly alone: each segment is cut out first, with its audio fades and any colour grade baked in at that step, then the segments concatenate, and sentence-case subtitles go on last. The finished MP4 lands in your project folder and you post it.
What this is not
Dragging the timeline seeks; it never moves a cut. There is no razor tool and no keyframes, and Kamply is not a plugin for Premiere, Final Cut, DaVinci Resolve or CapCut. It is not a general purpose editor either: a cut walks the same gated pipeline as everything else Kamply makes, so it wants a locked brief and an approved plan before it renders, and it hands you the file rather than publishing, scheduling or reporting on it. Kamply has no affiliation with Cursor, and the Mac app does not run inside it.
How it runs, start to finish
Three steps, in the order the app actually does them.
Drop the clips in
Your source clips sit in the video's takes/ folder, keeping the filenames they arrived with, and the EDL refers to each one by id and path. Whisper transcribes them and the JSON is cached in transcripts/.
Cuts come from the words
edl-pack groups the word timestamps into phrases, breaking on any silence of 0.5 seconds or longer and stamping each phrase with its start and end in seconds. The editor agent reads that file to choose cuts and writes them into edit.edl.json. No timecode is typed by hand.
ffmpeg renders it, gates read it
edl-render cuts each segment with its 30ms audio fades and any grade baked in, concatenates them, then burns sentence-case subtitles last. You watch a preview cut before the final render, and preflight checks the finished MP4 for freezes, dead holds, audio rate and loudness.
The numbers, and where they come from
Every figure on this page traces to a published source or to Kamply's own measurements. Nothing is modelled.
- Cut source
- Whisper word timestamps
- edl-pack groups the words into phrases, breaking on any silence of 0.5 seconds or longer.
- Assembler
- ffmpeg, no Remotion
- Per-segment extract, then a lossless concat by default, or a crossfade chain when a cut asks for one. A 30ms audio fade sits at every cut either way.
- Colour grade
- ASC CDL: field, warm or punch
- Optional, declared once per cut. The presets map to your brand field mode, the same vocabulary the stills grade uses.
- Audio master
- -14 LUFS, -1.5 dBTP
- One loudnorm pass. Kamply's audio master targets that level on every video it makes, so a cut lands at the same loudness as the rest of your work.
- Subtitles
- Sentence case, brand tokens
- Optional, and burned last when the EDL names a subtitle file. Kamply never burns uppercase subtitles.
- Hand edits in the app
- None
- The Studio timeline is a viewer. Claude writes the cut files; the timeline writes nothing back.
Questions people actually ask
If yours is not here, ask it in the walkthrough. The form below reaches a human.
Is Kamply made by Cursor or built on it?
No. Kamply is not made by Cursor, is not built on it, and the Mac app does not run inside it. People search this phrase because they know the pattern from code editors, where you describe the change, an agent makes it, and you review the result. Here the result is a cut of your own footage. The files Kamply writes are ordinary project files, so an editor like Cursor can open the same folder, but the app is its own thing.
Can I drag a clip or trim a cut by hand?
No. The timeline is read-only on purpose: hand-dragged timing would override the cuts Whisper measured, and Claude is the only thing that writes the cut files. The tab is called Studio rather than Editor because nothing in it edits.
Does it remove backgrounds from video, or only stills?
Both. Point nobg at a still and BiRefNet runs locally and writes a PNG with a soft alpha matte. Point it at a clip and it explodes the frames, mattes each with a single model load, and reassembles a ProRes 4444 .mov. It does not offer .mp4, because h264 drops the alpha channel. Green-screen keying is a separate command, with despill and a conform mode that scales and centre-crops a clip to 1080x1920 at 30fps. Background removal is opt in rather than part of the base install. The first time you ask for a cutout, nobg prints a one-time install command, and the model weights download on the first run after that.
Can it upscale low-resolution footage or rescue a soft shot?
No. There is no upscaler in the product, and the rule inside the app runs the other way. Stock footage is fetched at its original resolution because an upscaled frame reads soft on screen. A soft shot stays soft, so shoot it at the size you need.
Can it cut a two-person interview and keep the speakers apart?
No. Whisper drives the timestamps and it does not separate speakers, so a two-person interview cuts on word boundaries with no record of who said what. You can still cut it, you just sort the speakers yourself.
What do I need to run it, and what does it cost?
An Apple silicon Mac on macOS 11 or later. Kamply ships as a signed, notarized DMG. Onboarding runs the installer for you, ffmpeg included, and asks for your Mac password once for Homebrew plus one browser sign in. Two heavier pieces stay out of that first run, the Whisper transcriber and the background-removal model. The first time a job needs one, the tool stops and prints the one-time install command for you to run. One plan: $69 a week, $199 a month or $1,990 a year, with founding rates ending 2026-09-15.
