Key Features

Convert Long Video to Short Clips with AI

Find every clip-worthy moment

Upload one long recording and the long video to short video AI reviews the entire file, then pulls the strongest moments into separate short clips. This AI clip maker 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-by-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, colors, and placement. The AI video clip maker syncs captions to each word. For localized versions, continue with AI dubbing.

Vertical, square, and wide output

Use this video to Shorts converter to 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 centered 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 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 spokesperson 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

Podcasts and webinars into clips

Reach every market from one recording. The AI video translator converts each short clip into 177+ languages with lip-synced dubbing and the speaker's cloned voice, so one moment becomes a local post everywhere.

Product demos into feature clips

Product demos into feature clips

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

Polish old, low-resolution footage

Archive clips often look dated next to native uploads. Send 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

Training recordings into micro clips

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

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. Have a longer recording to mine for clips? Create the full episodes themselves with HeyGen's AI podcast generator.

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 video to Shorts converter sizes and captions each clip for the platform.

Will the AI pick the right moments to clip?

The AI surfaces moments as a set you review. Keep the strongest, drop the rest, and use each clip's Hook, Flow, Value, and Trend scores before you export.

How many short clips can one long video make?

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 reviewable set.

What length and file size of video can I upload?

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

How long should each short clip be?

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

Do the short clips include captions automatically?

Yes.But captions are optional. When enabled, each clip returns with captions timed to the speaker, drawn from a preset style library. You can restyle fonts, colors, 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 177+ 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?

HeyGen can tighten raw takes so cuts stay invisible, rebuild low-res footage up to 4K, and translate each clip into 177+ languages with dubbing, all in one workspace with no downloads between steps.

Can a small team keep a steady clip schedule?

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

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

Yes. You can use HeyGen as a free AI clip maker because AI Clipping is available to Free and paid users. Free exports include a watermark; paid plans include watermark removal.
