Yes, AI can edit a video for you from start to finish, if you pick the right kind of tool
Updated
AI can edit a short video for you from start to finish, but only some tools do the whole job. Caption tools and clippers do one part, and you finish the rest yourself.
In short
- AI can edit a short video from start to finish when the tool makes the whole edit, as Cutroom's Magic Editor and the Captions app do.
- Caption tools, clippers and one-click auto-editors each do part of the job, so you still finish the rest yourself.
- A long recording goes to a clipper. One short clip of you talking goes to a tool that makes the whole edit.
- In Cutroom the first edit costs 250 credits, and each change you ask Jacob for in the chat costs 40.
- A person is still the better choice for long recordings, several cameras or a brand's own fonts and motion templates.
Can AI edit a video for you from start to finish?
Yes, if the video is short and the tool is an editing agent. An editing agent cuts your mistakes, adds the captions and picks the b-roll itself. The first thing you see is a finished video.
- You watch the finished video and ask for changes in plain words, the way you'd tell a person who edits for you.
- Most AI features in video apps do one job, such as captions or silence removal. You put the rest together yourself.
- Long recordings work differently. A one-hour podcast needs a clipper to find the best moments, or a person to choose them.
- No AI edit is right every time, so watch the result before you post it.
What you still do yourself with each type of AI editor
Here is what each kind of tool does with the same 40-second clip of someone talking to camera.
- VEED says its auto subtitles are transcribed by AI and move in sync with your voice. The rest of the edit is still yours.
- OpusClip says it turns long videos into short clips. It's a clipper, so you still pick which clip to post.
- Submagic says it adds captions, removes silences, inserts b-roll and finds key moments automatically, and you fix the rest on the transcript.
- Descript calls Underlord an AI video agent and co-editor. It works inside Descript's editor: you ask for an edit, and you keep editing the rest yourself.
- The Captions app makes a video from your footage in the style you pick, and then takes changes you type in plain words.

How Cutroom's Magic Editor edits a video like this
Jacob is the AI editor inside Cutroom's Magic Editor: it edits your video for you, then changes it when you ask in a chat.
The 4 styles, as example edits
Steps
Three steps, four angles
Skit
Hook, hard stop, demo card
Verdict
The tester's verdict
Poster
Typography does the talking
Hover or tap an example to play it, without sound. These are example edits of each style; the presenters in them are generated with AI.
- Your take: one video of you talking, up to 3 minutes
- Your style: one of 4: Steps, Skit, Verdict or Poster
- Your files: screenshots, a screen recording or a logo, if you have them
- Your goal: what the video is for, in a few words, if you like
- Jacob makes it: normally 10 to 15 minutes, and you get an email
- Your edit: ask Jacob for changes in a chat, then export
Then you ask Jacob, for example
- “Make this about 10 seconds shorter”
- “Put a clip on the strongest sentence”
- “Change the music to something calmer”
Each change is a new version, and going back is free. First cut 250 credits, each change 40, questions free, export 30 credits per started minute.
What a one-press AI edit covers
Cutroom's Magic Editor turns one clip of you talking into a finished vertical video. Jacob, its AI editor, makes the whole edit, and you change it by asking in a chat.
- Jacob cuts the ums, false starts and repeats, and shortens long pauses.
- The captions follow your voice and stay in the language you speak.
- Jacob looks for b-roll in your own clip library first, then on the stock sites Pexels and Pixabay, and puts each clip on the words it belongs to.
- Your screenshots appear while you talk about them, your screen recording plays as the demo, and your logo closes the video.
- Each style adds music and sound effects, and you can ask Jacob to make them quieter or turn them off.
- The first edit normally takes 10 to 15 minutes, and you get an email when it's ready.
A trainer's 40-second tip, before and after the editing agent
One press in the Poster style, then two changes asked for in the chat.
Drawing of an example clip, not a customer video
Before · the clip as filmed
A 40-second phone video of a personal trainer giving one tip to camera
“Okay, so, um, most people warm up the wrong way. They stretch first, they, uh, they stretch first, when they should move first and stretch after.”
struck through = what Jacob cuts
After · Jacob's first edit, Poster style
“Most people warm up the wrong way. They stretch first, when they should move first and stretch after.”
- On “wrong”: the word set huge in stacked type
- On “stretch”: a black-and-white moment on that word
- Under the whole video: music and sound effects from the style, under your voice
- On “after”: your logo closes the video
Then you ask Jacob
- “Make the key words stand out more”v2the same edit with the key words standing out more
- “Change the music to something calmer”v3the same edit with calmer music under your voice
When a person should still edit your video
An AI edit is the wrong tool for some jobs. In these cases a person, or another kind of tool, does better.
- Long recordings need a clipper or an editor, because the Magic Editor takes one clip of up to 3 minutes.
- A video made from several clips or cameras needs an editor. The Magic Editor edits one clip per video.
- A brand with its own fonts and motion templates needs an editor. Each Magic Editor style comes with its own fonts, and you can't swap in yours.
- Bad sound needs fixing before the edit. Cutroom evens out the volume, but it doesn't remove background noise.
- Changing the order of what you said needs an editor. Jacob can cut a sentence but can't move it to another place.
- A wide or square version needs another tool. The Magic Editor exports one vertical MP4, 1080 by 1920.
Which kind to pick, and what it costs
Pick by what you start with. A long recording goes to a clipper, and one short clip of you talking goes to an editing agent. If you want to keep editing by hand, pick an editor with AI inside it.
- In Cutroom, a chat message that changes the video costs 40 credits, and the export costs 30 credits per started minute.
- On Lite, $19.99 a month, the credits pay for 4 finished videos of up to a minute each.
- Submagic's Starter plan takes videos of up to 2 minutes, and Captions shows its prices for the iPhone app.

Questions people ask
- Is there an AI that edits videos for you?
- Yes. Editing agents such as Cutroom's Magic Editor and the Captions app make the whole edit from your footage: the cuts, captions, b-roll and music. Caption tools and clippers do one part of the job, so you finish the rest yourself.
- What is the difference between an AI editing assistant and an editing agent?
- An assistant does the task you ask for inside an editor you still run, and you do the rest. An editing agent makes the whole edit first, and you ask for changes afterwards. Descript calls Underlord an AI video agent, and it works inside Descript's editor, where you keep editing yourself.
- Can AI edit a long video, like a podcast?
- Partly. A clipper such as OpusClip finds short moments in a long video, but you still choose and fix them. Cutroom's Magic Editor is built for one clip of up to 3 minutes, not a full episode.
- How long does an AI video edit take?
- In Cutroom's Magic Editor you press one button. The first edit normally takes 10 to 15 minutes, and you get an email when it's ready. You can close the page while Jacob works. Your video keeps going.
- Is there a free AI that edits videos?
- Yes. Descript's free plan includes limited use of Underlord, OpusClip and Captions have free plans, and VEED's auto subtitles are free to start. With Cutroom, your first video is free, no card, and you have 7 days to make it. It carries a Cutroom mark; Lite at $19.99/month removes it.
- Can I change what the AI did?
- Yes. In Cutroom you type the change to Jacob, for example "Put a clip on the strongest sentence". A message that changes the video costs 40 credits. Every change Jacob makes is a new version. The earlier versions stay, and going back to one is free.
Film one clip of you talking and let Jacob make the whole edit. Your first video is free.
