How to repurpose video content into a week of short clips
By Rakshit · Updated
To repurpose video content, pick one long video that has complete spoken ideas, cut it into vertical clips of 15 to 90 seconds, add captions, post a few clips a week and link each one back to the full video. AI can find and cut the moments. Choosing, posting and linking back stay with you.
Why one long video should not be one upload
A 45-minute interview costs hours to plan, record and edit, and then it gets one upload and one thumbnail. Inside it are a dozen moments that would stand alone, and almost nobody sees them because they are buried at minute 23. To repurpose video content is to pull those moments out and give each one its own short, vertical, captioned file.
This guide covers video only. It does not cover turning a talk into a blog post or a newsletter, which is a different job with different tools. If your source is a podcast, the same steps apply, and the podcast content repurposing guide adds the audio-side formats.
Step 1: pick a source that deserves the effort
Not every video repurposes well. The test is simple: can a stranger understand a 40-second slice without having seen the rest? That is true of people talking in complete thoughts and rarely true of a tutorial where the meaning sits on the screen.
- Good sources: interviews, panels, talks, webinars, Q&As, finished live streams, podcast episodes recorded on camera.
- Weak sources: screen recordings, slideshows and music videos, where a clip needs the picture to make sense.
- Rights first: use video you own or have permission to cut. Crediting the owner does not turn a copy into fair use, YouTube says on its help page, and the U.S. Copyright Office says no formula makes a set number of seconds safe.
Step 2: cut for moments, not for minutes
Cut where an idea starts and ends, then check the length. Platforms are generous here. YouTube categorises square or vertical videos up to three minutes as Shorts, and Instagram says it recommends videos of three minutes or less to people who do not follow you yet. In practice the better clips are shorter than the limit, because a single idea rarely needs more than a minute.
| Clip length | KeyMo range | Good for |
|---|---|---|
| Short | 20 to 40 seconds | One sharp point, a joke, a hot take |
| Medium | 40 to 60 seconds | A small story or a stated opinion with a reason |
| Long | 60 to 90 seconds | An explanation that needs a setup and a payoff |
| Auto | 15 to 90 seconds | Let the tool pick per moment |
Doing this by hand means scrubbing the whole file, which is why most people stop after two clips. This is the step AI helps with most. KeyMo scores every candidate out of 10 with a one-line reason and keeps only clips that score 7 or higher, so a weak video gives you fewer clips rather than filler.
Step 3: reformat and caption
A clip cut from a 16:9 video needs to become 9:16 with the speaker in the middle of the frame. Do not fake it with black bars: YouTube advises against adding padding or black bars to the video itself, and TikTok gives the same advice for landscape uploads. Reframe the shot instead.
Then add captions, because many people watch short video with the sound off. Word-by-word captions that match the speaker keep the eye moving. KeyMo offers 12 caption styles plus a no-captions option, face-tracking 9:16 reframe, and trims silences. Each clip comes out at 1080x1920, 30 fps, with no watermark on any plan.
Step 4: spread the clips across the week and link back
A worked example. A 45-minute interview falls in KeyMo's 8 to 12 clip target for videos up to 60 minutes (a built-in target, not a promise). Say you get ten clips. Do not post all ten on Monday. Post your strongest first and hold the rest.
- Monday: the clip with the highest score and the cleanest opening line, on your main short-form platform.
- Tuesday and Wednesday: the next two, each one on a different platform so the same viewers do not see the same file twice in a row.
- Thursday: a clip that disagrees with or complicates Monday's, to reward people who watched it.
- Friday: the clip that sums up the whole interview, posted with the full video's link.
- Weekend: keep the remaining clips as a reserve for a slow week.
Linking back means putting the full video's link wherever that platform lets you add one: the description, a pinned comment or your profile. A clip that points nowhere can grow its own views while the full video stays unseen.
What KeyMo covers and what it does not
| Step | Who does it |
|---|---|
| Choose the video and confirm you have the rights | You |
| Find the best moments and score them | KeyMo |
| Cut to 9:16, track the face, trim silence | KeyMo |
| Caption in one of 12 styles | KeyMo |
| Fix a word or tighten a cut | You, by telling the chat editor |
| Export all clips as a ZIP | KeyMo |
| Schedule and post | You. KeyMo does not post or schedule |
| Link back to the full video | You |
Upload an MP4 or MOV of 5 minutes to 3 hours, up to 10 GB, or paste a YouTube link on a paid plan. Starter is $12 a month for 300 source minutes and Pro is $29 a month for 900. There is no free plan. If your source is a long video you want cut into Shorts, the long video to Shorts page shows the flow, and pricing lists the plans.
