Key features

Long video to short video features

Find every moment worth clipping

Upload one long recording and the AI reviews the entire file, then pulls the strongest moments into separate short clips. It reads speech, pacing and emphasis to cut at natural boundaries, so each clip stands on its own instead of ending mid-sentence or trailing off.

AI reviewing a long recording and pulling the strongest moments into short clips.

Word-for-word captions, built in

Every clip comes back with animated captions timed to the speaker, styled from a preset library you can restyle for fonts, colours, and placement. Burned-in captions keep viewers watching on muted feeds, and the subtitle generator syncs them to each word.

Vertical, square, and wide output

Set each clip to 9:16 for Shorts, Reels and TikTok, 1:1 for feeds, or 16:9 for wide players, from a single upload. Subject tracking keeps the speaker centred in the vertical frame, so nothing important drifts out of the shot as the framing shifts.

Clip reframed to vertical, square, and wide aspect ratios from one upload.

Clips without filler, with clean cuts

Tighten a rambling take before you clip it. Speech cleanup removes filler words, pauses and false starts, then rebuilds the frames between cuts so the tightened clip plays as one continuous take with no visible jumps, unlike audio-only cleanup tools.

Generate avatar intros and outros

Clipping existing footage is only part of the job. Record a short branded intro, a call-to-action outro, or a missing line with an AI avatar that speaks your script, then stitch it onto any clip so the short opens and closes the way you want.

Use cases

Long-to-short video use cases

Turn podcasts and webinars into clips

Turn podcasts and webinars into clips

A one-hour episode hides a dozen quotable moments. Run it through the clip generator and get a batch of short clips that draw new listeners to the full recording, with no manual scrubbing.

Turn YouTube long videos into Shorts

Turn long YouTube videos into Shorts

Stop letting old uploads collect dust. Point the tool at a long-form YouTube video and it returns vertical clips sized for Shorts, each linked back to the source to send new viewers to your channel.

Localise every clip in 175+ languages

Localise every clip in 175+ languages

Reach every market from a single recording. The AI video translator converts each short clip into 175+ languages with lip-synced dubbing and the speaker's cloned voice, so one moment becomes a local post everywhere.

Turn product demos into feature clips

Turn product demos into feature clips

Prospects rarely watch a full demo. Break a long walkthrough into short clips that each show one feature, so sales and marketing can drop the right moment into an email or social feed.

Polish old, low-resolution footage

Polish old, low-resolution footage

Archive clips often look dated next to native uploads. Run them through the AI video upscaler to rebuild detail up to 4K and smooth motion before you post the short.

Training recordings into micro clips

Turn training recordings into micro clips

Long training sessions lose people’s attention. Clip each recorded session into short lessons that cover one topic, so employees can watch between tasks, and update any clip by regenerating it instead of re-recording.

How it works

How to turn long videos into short clips

Go from a long recording to a batch of publish-ready short clips in four steps, most in under five minutes.

Step 1

Upload or paste a link

Drop in an MP4, MOV, or WEBM up to 10GB, or paste a YouTube or Google Drive link instead.

Step 2

Let AI choose the moments

The AI scans the full recording and turns the strongest segments into separate short clips.

Step 3

Caption, reframe, brand

Add word-by-word captions, switch to 9:16, 1:1, or 16:9, and apply your logo and colours.

Step 4

Export and post anywhere

Download each clip, or publish straight to your social channels with no extra editing needed.

Long video to short video FAQs

What is a long-video to short-video converter?

A long video to short video converter uses AI to scan a full recording, find the strongest moments, and turn them into short, captioned clips sized for Shorts, Reels, and TikTok. You upload once and get a batch of ready-to-post clips instead of editing by hand.

How do I turn a long YouTube video into Shorts?

Paste the video link or upload the file, then let the AI detect highlights and reframe them to 9:16. Review the set, keep the strongest, and export. The YouTube Shorts workflow sizes and captions each clip for the platform.

Will the AI choose the right moments to clip?

The AI reads speech, pacing, and emphasis to surface complete, self-contained moments, not random cuts, and returns them as a set for you to review. Keep the strongest, drop the rest, and tweak any clip's in and out points in the editor before you export.

How many short clips can one long video create?

It depends on the length and density of your recording. A longer video usually yields more clips, since the video highlight engine surfaces every strong moment across the file and returns them as a set you can review.

What video length and file size can I upload?

You can upload MP4, MOV, or WEBM files up to 10GB, and process source videos up to two hours long. A 30-minute webinar and a 90-minute training session both work without trimming first. You can also paste a YouTube or Google Drive link.

How long should each short video be?

Most repurposed clips land between 20 and 60 seconds, short enough for one clear payoff and within the range Shorts, Reels, and TikTok favour. You set the target length before generating, so every clip comes back trimmed to the duration you want.

Do the short clips automatically include captions?

Yes. Every clip comes back with word-by-word captions timed to the speaker, drawn from a preset style library. Captions are burned in by default, which matters because most social video is watched on mute. You can restyle fonts, colours, and placement before export.

Can I add an intro that wasn’t in the original?

Yes. Beyond clipping existing footage, the AI video generator creates a branded intro, outro, or missing line with an avatar that speaks your script. Stitch it onto any clip so the short opens and closes on brand.

Can I turn each short clip into other languages?

Yes. After clipping, translate any clip into 175+ languages with lip-synced dubbing and the speaker's cloned voice, not just translated subtitles. One strong moment becomes a native-sounding post for every market you serve, without re-recording.

How is this different from other AI clip tools?

Most clip tools stop once they cut and caption. HeyGen keeps working: tighten raw takes so cuts stay invisible, rebuild low-res footage up to 4K, and translate each clip into 175+ languages with dubbing, all in one workspace with no downloads between steps.

Can a small team keep a consistent publishing schedule?

Yes. Turning every webinar and recording into a batch of clips removes the per-clip editing bottleneck. Attention Grabbing Media reported content creation across campaigns was three times faster with HeyGen's video tools.

Is the long video to short video tool free to use?

Yes. You can turn long videos into short clips on the free plan, without watermarks, and paid plans add more languages, higher resolution, and volume for teams. Pricing starts free and scales up to custom enterprise plans.
