Convert a YouTube video to Reels

By the KeyMo team · Updated

To convert a YouTube video to Reels, paste the link or upload the file into KeyMo. It picks the strongest moments, scores each one out of 10, reframes them to vertical 9:16 with captions and no watermark, and exports up to 15 clips. You then upload the files to Instagram yourself. KeyMo has no free plan or trial.

How to turn a YouTube video into Reels with KeyMo

A Reel is a short vertical video, and a YouTube episode is a long horizontal one. Converting means finding the few minutes worth posting, cropping them to a vertical frame that keeps the speaker in view, and adding captions. KeyMo does those three jobs in one pass. This is the full flow, using only what the product does today.

  1. Pick a plan. Pasting a YouTube link needs a paid plan: Starter is $12 a month for 300 source minutes and Pro is $29 for 900. Yearly billing is ten times the monthly price. There is no free plan and no trial.
  2. Add the video. Paste the YouTube link, or upload an MP4 or MOV file. Sources run from 5 minutes to 3 hours and up to 10 GB. Link import fetches up to 1080p, and you confirm you own the video or have permission to use it.
  3. Choose a clip length: Auto (15 to 90 seconds), Short (20 to 40), Medium (40 to 60) or Long (60 to 90).
  4. Let KeyMo find the moments. Each clip gets a score out of 10 and a one-line reason. Only clips scoring 7 or higher are kept, so a weak episode returns fewer clips instead of filler.
  5. Check the look. Captions are word by word, in one of 12 styles or switched off. The reframe follows the speaker's face, and silence is trimmed.
  6. Fix anything in the chat editor. Open a clip and tell KeyMo what to change. Edit mode accepts clips from 15 seconds to 10 minutes, and there is a music library sorted by mood.
  7. Export. Download all clips as one ZIP and upload the ones you want to Instagram. Source files are kept for 7 days and finished clips for 30.

What a Reel needs, and what KeyMo exports

Instagram and Meta publish the numbers below on their own help pages, read on 11 October 2026. The right-hand column is what KeyMo exports, so you can compare the two by eye. For the full numbers see the Instagram Reels aspect ratio and Reels length pages.

KeyMo outputs exactly one shape, vertical 9:16. That fits Reels and Facebook Reels. It does not make a square or a 16:9 version, so it is the wrong tool if you need those from the same run.

What you get, and what you do not

You getYou do not get
Up to 15 vertical clips from one videoA 16:9 or square export. Output is 9:16 only

Clips kept 30 days, sources kept 7Videos shorter than 5 minutes or longer than 3 hours

The clip targets are built-in goals, not measured results: 3 to 5 clips from a video up to 15 minutes, 5 to 8 up to 30 minutes, 8 to 12 up to an hour, and up to 15 from longer ones.

A worked example: a 45-minute interview

Say you run a channel with a 45-minute interview posted on YouTube, and you want to feed Instagram for a week. On Starter, 300 source minutes covers six videos of that length in a month. On Pro, 900 covers twenty.

For a video of that length KeyMo aims for 8 to 12 clips. If the guest rambles for the first half, fewer clips will clear the 7 out of 10 bar, and that is the intended behaviour. Post the two or three with the highest scores first, since each one comes with a reason you can read in a few seconds.

  • Pick Short (20 to 40 seconds) for hot takes and one-line answers.
  • Pick Medium (40 to 60) for a story with a setup and a payoff.
  • Pick Long (60 to 90) for an exchange that needs room to land.
  • Leave it on Auto if you are unsure; it chooses between 15 and 90 seconds per clip.

Who this suits, and who should look elsewhere

  • If your source is a talking-head video such as a podcast, interview, lecture or webinar, KeyMo fits. Moments are found from speech, so the content matters more than the camera work.
  • If you need a free converter, KeyMo is not it. Instagram's own editor can scale, crop and rotate clips from your camera roll, but you find and cut every moment by hand.
  • If you want scheduling or auto-posting, use a separate tool after KeyMo. It does not publish.
  • If you are weighing tools, read KeyMo vs Opus Clip and KeyMo vs Klap for a side-by-side read of what each vendor publishes.

Using a YouTube video you do not own

KeyMo asks you to confirm you own the video or have permission before it imports a link. That is the right question. YouTube's own copyright page says crediting the owner does not turn a non-transformative copy into fair use, and that phrases like "no infringement intended" will not protect you. The U.S. Copyright Office adds that fair use is decided case by case, with no set percentage or clip length that is automatically safe.

So the practical rule is simple. Convert your own videos freely. For someone else's video, get written permission first. Instagram's help pages say they cannot give legal advice, and neither can this page. The guide on clipping YouTube videos legally goes through the sources in more detail.

FAQ

Can I convert a YouTube video to Reels for free?

Not with KeyMo, which has no free plan and no trial. The alternative is Instagram's own editor, which can scale and crop clips from your camera roll, but you pick and cut every moment by hand.

What size should a Reel made from a YouTube video be?

Vertical 9:16 is the safe choice. Instagram accepts ratios from 1.91:1 up to 9:16 and states a minimum of 30 FPS. KeyMo exports 9:16 at 1080x1920 and 30 fps.

How long can a Reel from a YouTube video be?

Instagram Help says up to 20 minutes can be recorded and edited, but reels over 3 minutes are not recommended to new audiences. KeyMo makes clips of 15 to 90 seconds.

Can the same clips go to a Facebook Reel?

Yes. Meta says Facebook Reels can be any length or orientation, and its composer works inside a 9:16 frame. The vertical files KeyMo exports fit that frame.

Will KeyMo publish the finished Reels to Instagram?

No. KeyMo exports the clips, usually as one ZIP, and you upload them in Instagram yourself. You keep control of the caption, cover and posting time.

Do I need permission to make Reels from someone else's YouTube video?

Assume yes. Fair use is decided case by case and there is no safe clip length, so ask the owner. KeyMo also asks you to confirm you own the video or have permission before importing a link.
