What you’ll be able to do

Right, so by the end of this you’ll be able to take a rough, rambly video, hand it to a tool, and get back something with captions burned in, the silences gone, and the waffle cut out. No timeline scrubbing. No manually typing subtitles at 2am. You still need to check the work, but the boring bit, the bit that eats your evening, that gets done in minutes.

This isn’t about making a video from nothing. That’s a different guide (more on that later). This is about taking something you’ve already filmed and turning it from a mess into something watchable.

Before you start

You don’t need much. A video file, something to edit it on, and a bit of patience for the first go. That’s genuinely it.

Here’s the bit worth slowing down for though: what stays on your machine and what doesn’t. If you’re using a desktop tool like DaVinci Resolve, your footage stays local, it’s just your computer doing the processing. If you’re using something browser-based, like Veed, or a cloud service like Opus Clip, you’re uploading your actual video file to someone else’s server. That’s fine for most things. It’s not fine if the video has anything sensitive in it, work you’re not allowed to share, kids in the background, someone else’s private info, that kind of thing.

Keep your original files. Always. Every tool here works from a copy, and you want the untouched version sitting safely somewhere in case an edit goes wrong or you change your mind later.

Get set up

There’s no single “AI video editor” that does everything. Different tools solve different annoyances, so pick based on what’s actually bugging you.

If your main problem is that you talk too much and need someone (something) to cut the dead air and add captions fast, CapCut’s free tier does auto-captions, removes silences, and resizes your video for social in a few taps. It’s the easiest starting point if you’ve never touched an editing tool before.

If your problem is more “I said ‘um’ four hundred times and rambled for ten minutes when I meant to talk for three”, Descript is the one to look at. It turns your video into a transcript, and you edit the video by editing the text. Delete a sentence, the clip disappears. It also strips out filler words automatically, which is oddly satisfying to watch happen.

If you’re already comfortable editing and just want AI to speed up specific jobs, Adobe Premiere Pro has text-based editing now, plus a generative extend feature for stretching clips. That’s more for people who already know their way around a timeline though, not a first-timer tool.

DaVinci Resolve is free, and the paid Studio version adds AI tools on top, but it’s a proper editing suite with a learning curve. Worth it if you want to grow into video editing, less so if you just want one video sorted by Friday.

And if you’ve got a long video, a podcast recording, a webinar, a rambly vlog, and you want short clips out of it for social media, Opus Clip and similar tools are built exactly for that: feed in the long version, get short, captioned clips back.

For most complete beginners, I’d start with CapCut or Descript. CapCut if you want speed and simplicity. Descript if you want more control and don’t mind a slightly steeper first ten minutes.

Try it yourself

Once you’ve picked a tool, most of the AI heavy lifting inside these apps happens through buttons, not prompts, the auto-caption button, the “remove silences” button. But several of these tools (and general assistants like ChatGPT, Claude, or Gemini) also let you type instructions, especially for cleanup tasks and text-based edits. Here are three that do different jobs.

For tidying up auto-generated captions once they’re exported as text (paste your caption file or transcript in):

Here's an auto-generated transcript from my video. Fix any spelling mistakes, especially names and technical terms, but don't change the wording or meaning of anything I actually said. Keep the timestamps exactly as they are. Return it in the same format.

For cutting a rambly transcript down before you do a transcript-based edit in Descript or similar:

Here's a transcript of a video I recorded. I want to cut it down to the key points only, removing rambling, repeated ideas, and filler. Don't rewrite what I said, just tell me which sentences to cut, quoting them exactly so I can find and delete them in my editor.

For writing a title and description once your video’s edited (paste a short summary or the transcript):

Here's a transcript of my video. Write me three short, plain title options and a two-sentence description for YouTube. No hype words, no clickbait, keep it accurate to what's actually in the video.

That third one’s genuinely useful, by the way. Titles are always the bit I put off.

Check the result

Before you publish anything, actually watch it back. All the way through, sound on. I know that sounds obvious but it’s the step people skip because they trust the tool too much.

Specifically, check:

Do the captions match what you actually said? Auto-captions get names wrong constantly, and any jargon or technical terms in your field, forget it, they’ll butcher them. If you said “Kubernetes” it might’ve heard “cucumbers.” I’m not exaggerating much.

Did the silence-removal cut anything important? Sometimes a pause was for effect, not because you forgot what to say. Check nothing got chopped that changed your meaning.

If you used a transcript-based cut, read the final transcript against your memory of the recording. Does it still make sense as a flow of ideas, or does it jump oddly because two unrelated points got stitched together?

Play it on your phone, not just your laptop, especially if it’s going on social media. Captions that look fine on a big screen can be too small or badly positioned on mobile.

And check the audio levels didn’t drop out anywhere during the silence removal. Occasionally a tool trims a touch too aggressively and clips the start of a word.

None of this takes long. Ten minutes, maybe. But it’s the ten minutes that stops you publishing a video where the AI thinks you run a company called “Adapt Progress Evil.”

If it doesn’t work

Captions wrong in a lot of places, not just the odd name? Try again with a clearer audio source if you have one, background noise and mumbling are the usual culprits. Most tools do better with clean, close-mic’d audio than with a laptop mic across a room.

Audio still messy after cleanup? Some tools handle background hiss and echo better than others. Descript and Premiere both have dedicated audio cleanup features that are more thorough than a basic auto-caption tool’s built-in denoise. Worth trying a different tool for just that step if your first choice isn’t cutting it.

Cut the wrong bit? This is exactly why you keep the original file. Undo, or start the edit again from scratch. Never edit your only copy of anything.

Now, the bit that matters more than any of that: what not to hand over in the first place. If your video has anyone else’s personal information in it, faces you don’t have permission to share, financial details, health information, anything under an NDA, don’t upload it to a cloud tool, and be cautious even pasting the transcript into a chat assistant. Local tools like DaVinci Resolve keep things on your machine. Cloud tools and browser-based ones don’t. If you’re not sure whether something’s sensitive, treat it like it is.

Also worth saying: don’t assume an AI tool has read and understood the meaning of your video. It’s pattern-matching sound to text, and text to editing suggestions. It doesn’t know your industry, your inside jokes, or that “Dave” is definitely not spelled “Dav.” That’s your job, still.

Keep exploring

If you’re starting from nothing rather than a rough recording, have a look at “How to get AI to make a video.” If you’ve got audio you need turned into text, on its own, without the video edit, “How to get AI to transcribe an audio recording” covers that. And if you just want the gist of a long video someone else made, without watching the whole thing, try “How to get AI to summarise a YouTube video.”
