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-perfect captions, built in

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

Short clip with animated word-by-word captions synced to the speaker.

Vertical, square, and wide formats

Set each clip to 9:16 for Shorts, Reels, and TikTok, 1:1 for feeds, or 16:9 for wide players, all 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.

Filler-free clips with smooth, 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 reads 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 exactly the way you want.

Use cases

Long-to-short video use cases

Turn podcasts and webinars into short clips

Turn podcasts and webinars into short clips

A one-hour episode hides a dozen quotable moments. Run it through the clip generator and get a batch of short clips that attract new listeners to the full recording, without any manual scrubbing.

Turn long YouTube videos into Shorts

Turn long YouTube videos into Shorts

Stop letting old uploads sit idle. Point the tool at a long-form YouTube video, and it will generate vertical clips sized for Shorts, each linked back to the original video to send new viewers to your channel.

Localise every clip in 175+ languages

Localise every clip in 175+ languages

Reach every market with 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 turns into a local post for every audience.

Product demos into feature snippets

Product demos into feature snippets

Prospects rarely watch an entire demo. Break a long walkthrough into short clips, each highlighting a single feature, so sales and marketing teams can insert the most relevant moment into an email or social feed.

Enhance old, low-resolution footage

Enhance old, low-resolution footage

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

Training recordings into micro clips

Training recordings into micro clips

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

How it works

How to turn long videos into short clips

Turn a long recording into a batch of publish-ready short clips in four simple steps, usually in under five minutes.

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

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, identify the most impactful 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 having to edit everything manually.

How can I convert a long YouTube video into Shorts?

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

Will the AI select the right moments to clip?

The AI analyses 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 ones, drop the rest, and adjust any clip’s in and out points in the editor before you export.

How many short clips can be created from one long video?

It depends on the length and density of your recording. A longer video usually gives you more clips, since the video highlight engine picks out every strong moment in the file and returns them as a set you can easily 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 needing to trim first. You can also paste a YouTube or Google Drive link.

How long should each short video clip be?

Most repurposed clips end up between 20 and 60 seconds, short enough for one clear payoff and within the range that Shorts, Reels, and TikTok prefer. You set the target length before generating, so every clip comes back neatly 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, taken from a preset style library. Captions are burned in by default, which is important because most social video is watched on mute. You can restyle fonts, colours, and placement before export.

Can I add an introduction that was not 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. You can stitch it onto any clip so the short opens and closes fully on brand.

Can I convert each short clip into other languages?

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

How is this different from other AI video clip tools?

Most clip tools stop after they cut and add captions. 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 needed between steps.

Can a small team maintain a consistent clip schedule?

Yes. Converting every webinar and recording into a batch of clips removes the per-clip editing bottleneck. Attention Grabbing Media reported content creation becoming 3x faster across campaigns with HeyGen's video tools.

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

Yes. You can convert long videos into short clips on the free plan without any watermark, and the paid plans add more languages, higher resolution, and higher volume suitable for teams. Pricing starts with a free plan and scales up to fully custom enterprise plans.
