How to clip videos with AI, step by step

AI clipping works on what people say. Clyper, for one, picks its moments by reading the video's transcript: YouTube's captions when the video has them, its own transcript of the audio when it doesn't. OpusClip says in an article on its API that talking-head content is where its model performs best. So the videos that clip well are the ones where the talking carries the moment:

• Clips well: podcasts and interviews, one person telling stories or giving strong opinions, commentary, talks and Q&As, and streams with a camera on the streamer. Each is full of moments that work on their own.
• Harder: music, gameplay with nobody talking, and videos where what matters is on screen (a chart, a demo, a trick) rather than in what's said. OpusClip's article says music-driven and animation-heavy content scores conservatively. For gaming streams there are tools built around the game: Eklipse's help center says its viral score weighs chat activity, voice intensity and visual motion around a moment.
• Clear sound helps. A transcript is only as good as the audio, and words lost under music or crosstalk are lost to the tool too. Speech recognition isn't equally good for everyone, either: the model card for OpenAI's Whisper says its models perform unevenly across languages and on different accents and dialects.

And clip videos you're allowed to clip: your own, a client's, or one from a creator who runs a clipping campaign or program. See is clipping legal? and the streamers and creators who pay clippers.

Most AI clipping tools take a YouTube link, a video file, or both. A link is quickest, with nothing to download. A file is the way in for anything that isn't on YouTube, like a Zoom call, a Twitch replay or a podcast recorded on your computer.

In Clyper, paste any public or unlisted YouTube video from 1 minute to 4 hours long, including Shorts and livestreams that were saved. Private, members-only and age-restricted videos, and streams that are still live, don't work. Or upload an MP4, MOV, WebM or MKV file up to 4 GB.

Not every tool takes every link. Some take uploads only, and some ask you to confirm the YouTube channel is yours, which rules out a campaign's videos. AI clipping tools compared lists what each one takes, and how AI clip generators work covers what else to weigh before you pick one.

For a stream, work from the replay: download it and upload the file, as Twitch VOD to clips shows. Kick added its own VOD download on September 25, 2026, though its help center still describes third-party tools; more in Kick VOD to clips.

Tools differ in what they let you set, but four settings come up again and again, and each one changes what you get back:

How many clips. On Auto, Clyper picks about 10 clips an hour of video, up to 10, and returns fewer rather than pad the list with weak moments. Choose a number instead and you get that many if the video holds them: up to one for every 2 minutes of video and 30 from one video, so 15 from a 30-minute episode. The extra ones are the next-best moments, and their hook scores say so. The number doesn't change the credits a video uses. Other tools decide for you: OpusClip's help center says its count depends on the video's length and the model you use, from 1 or 2 clips for a video under 3 minutes to 23 to 32 for one of 30 to 60 minutes.

Clip length. OpusClip sets it in CoPilot before a project runs, and it starts on Auto, 0 to 3 minutes. Vizard's API takes auto, under 30 seconds, 30 to 60 seconds, 60 to 90 seconds, or 90 seconds to 3 minutes. Clyper has no length setting: each moment runs 20 to 60 seconds, from where it starts to where it pays off, and you trim or extend it later. Shorts can now run up to three minutes, but a clip should be as long as its moment; see how long a short video should be.

Caption style. Plenty of people watch with the sound off, so the captions carry the clip. Clyper has 5 styles: Pop (three words at a time, the spoken word turning blue) on every plan, and Karaoke, Highlight, One word and Plain on Pro and Studio, which can also save styles of your own with your fonts and colors. You can switch a clip's style later, so this is only the starting point. See them all on animated captions.

Hook headline. A short line at the top of the frame that tells a viewer why to keep watching. On Pro and Studio, Clyper can open every clip with its hook as a headline for the first 4 seconds, and you can change or remove it on any clip. Submagic's Magic Clips can generate a hook title too. If your tool has none, write your own: the free hook generator has formulas to start from, and hook examples for short videos has plenty more.

An AI clipping tool gives you candidates, not finished posts. Clyper sorts its clips by hook score, so the ones it rates strongest come first, each with its rank and score on it. Go through them in that order, and give each one the same quick check:

1. Read the title and the first line. The title says what the clip is about. If the first line, read on its own, wouldn't make you stay, the clip needs a better opening or a headline.
2. Watch the first and last three seconds. A clip should open on the start of a sentence and end right after its payoff, not on “and so” or a beat before the punchline.
3. Watch it once as a stranger would. Does it make sense without the rest of the video? A “he” nobody introduced, or “like I said”, means it needs more setup or a later start.
4. Skip to each change of speaker. The frame should move to whoever is talking, and nobody should be cut in half when two people share the shot.
5. Read the captions with the sound on. Speech recognition gets names, brands, slang and jargon wrong more often than everyday words, and the Whisper model card notes that its output can include words nobody said. A misspelled name in the first line is what a viewer notices.

Then put each clip in one of three piles: post it as it is, fix it, or skip it. The next step is the second pile. For why AI clip generators make the mistakes they do, see where AI clipping goes wrong.

Most fixes are small, and a good AI clipping tool lets you make them without starting over. In Clyper, each clip opens in an editor that previews your changes as you make them:

• Trim to the word. Drag either end, or move it a word at a time; ends snap to where words start and stop. Cut a slow first sentence so the clip opens on its hook, or end it right on the payoff.
• Extend either end by up to 15 seconds, when a clip starts a beat late or cuts off the answer. For a YouTube link, only those extra seconds are downloaded.
• Fix a caption word. Tap it and type the right one; its timing stays where it was. Leave it empty to hide it, for a stray “um”.
• Switch the caption style, and see it on the clip before it renders.
• Change or remove the headline on Pro and Studio, or put back the hook title Clyper wrote for the clip.

Nothing renders until you save, edits don't use credits, and each clip can be rendered up to 10 times. Every clip downloads as a 1080 × 1920 MP4 with no watermark, as it was made or as you edited it.

What an editor can't fix is a moment that doesn't work. If a clip needs the five minutes before it to make sense, skip it and post the next one. Clyper's editor changes a clip's length, captions, style and headline, not its framing, so if the frame misses the speaker for a stretch, trim that stretch out.

With the clips checked, post them in order of strength: the scores as a starting point, your own judgment for the rest. Your best clip gets the most time to find its audience when it goes out first, and on a campaign, it goes out while the budget lasts.

• Upload each one to each app rather than sharing from one app to another, so no other app's watermark ends up on it. How to cross-post short videos covers posting one clip to TikTok, Reels and Shorts.
• Write the post. The caption and title are still yours. Check their length for each app with the free social media character counter.
• Spread them out. One long video can be a week of posts. Plan it with the content calendar generator and line them up with how to schedule TikToks, Reels and Shorts.
• On a campaign, follow the brief: its tags, its length, its rules. Why clipping campaigns reject clips covers the usual reasons.

Then let the numbers teach you. On Shorts, YouTube's analytics show Stayed to watch: the percentage of times viewers stayed past the initial seconds of a Short. Compare it across your clips. The ones people stay for show you which openings work, and that's what to look for in the next video. Posting to several pages? See how to run multiple clip accounts.

An AI clipping tool picks from what's said, so it can miss a moment carried by a look, a play or a silence, and on a long video it may simply rank a moment below the ones it kept. If you know a moment that isn't among the clips, from the Most replayed graph, the chat or a time in the comments, cut it yourself:

• The free video clipper cuts several clips from one long video at once, by marking them or pasting timestamps, kept as they are or made vertical, in your browser.
• The free video highlight finder finds the liveliest moments in a file by their sound: the laughs, the shouts, the hype.
