Which recordings do you want to turn into clips?

Pick complete moments from interviews, podcasts and explainers, then add captions and your brand style.

One video batch includes up to 30 source-video minutes and 3 clip drafts.

Review every clip before sharing. No automatic publishing, voice cloning or invented speech. Views, engagement and virality are not guaranteed.

What is included

Upload an authorised recording and receive editable clip drafts with source timestamps, caption templates and portrait framing. Keep the source and edit settings for later changes.

Includes topic-led moment selection, editable cut points, caption templates, portrait framing and downloadable video with subtitle files. Use a speaker crop, split-screen or full-frame layout; uncertain crops stay flagged for review. Sports highlights and visual-only storytelling need different models and scope.

Maximum clip duration: up to 60 seconds.

Minimum clip duration: at least 15 seconds.

Maximum source height: up to 1,080 pixels.

Maximum frame rate: up to 30 frames per second.

Maximum source file: up to 1 GiB.

Caption templates: 3 styles.

Brand setup: 1 brand.

Caption timing tolerance: up to 200 milliseconds.

Minimum useful clips when suitable moments exist: at least 2 clips.

Maximum audio-video drift: up to 100 milliseconds.

Reference render capacity per worker: 4 physical CPU cores.

Reference render memory per worker: 8 GiB.

What should make a clip ready for review?

A useful short clip makes sense on its own, keeps the speaker's meaning and needs little caption or framing correction.

How these standards are measured

Test on unseen recordings with editor-labelled moments. Score complete meaning, caption accuracy, safe framing and timing. Count rejected drafts and recordings with no usable output, not just successful exports. Never stitch speech into a claim the speaker did not make.

Targets for your selected standard
What is checkedTarget
Clips accepted for light editingAn editor accepts the topic, complete meaning, context and cut points using a rubric agreed before testing. Count every requested draft, including duplicates and failures. Report no-output recordings and useful-clip yield separately.≥80%
Caption word accuracyCompare captions with a human transcript using word substitutions, deletions and insertions. Preserve names, numbers and negation; meaning-changing errors block sharing even if the overall score passes.≥97%
Important content kept in frameInspect frames sampled across every output clip plus all cut and layout changes. Check the speaker, slides and caption safe areas; unresolved crop failures count as failures, not excluded samples.≥98%
Caption timing within toleranceCompare caption boundaries with the reference audio timing. Check audio-video drift independently and reject exports with missing or clipped speech.≥95%
Exports pass technical checksValidate duration, dimensions, frame rate, readable captions, decodable video and intact audio for every requested export. Deliver subtitle files and cut settings; a successful render alone does not prove editorial quality.≥100%

Meaning-changing edits, fabricated speech or unauthorised footage block sharing. Technical success and an AI score do not replace editorial approval.

How quickly do you need the clips?

Choose how soon the previews and exports should be ready. Your review time is separate.

Timing details

Start after the complete source file is available to the workflow. Include audio extraction, transcription, selection, captions, framing, queueing, retries and rendering. Upload time is shown separately; a requested new edit or batch is another run.

The target applies to at least 95% of agreed test runs, with 2 in progress at a time.

How much do you want to spend per video batch?

Choose the machine budget for finding moments, transcribing speech and rendering the clip drafts.

Cost details

Includes transcription, model calls, rendering, retries and shared hosting at the stated volume. A video batch is not a published clip: count failed runs and re-renders. Human editing, original recording and the calling agent are separate.

Reference machine cost: $2.34 – 6.34 per video batch at 10 video batches a month. The selected cap is a target to test, not a replacement for this estimate.

Where do you want it to run?

Run in your cloud or on a machine you control. Choose whether audio and transcripts can go to approved AI APIs.

Data and access details

Runs in a cloud account you control, with access controls and logs.

Audio and selected transcript context go to approved speech and text APIs. Agree retention before processing.

Only process recordings and brand assets you are allowed to use. Offline mode uses local files and private speech and text models, without cloud-folder pickup.

How do you want to use it?

Use a preview web page, connect your existing agent or run a dedicated clipping agent.

Anything else your provider should know?

Optional. Your choices are included automatically.

Common questions

When should I subscribe instead?

Subscribe if a ready-made clipping tool gives you the templates, editor and volume you need. Buy a workflow when you need control over deployment, your review process or integration with your own tools.

Will it find viral moments?

It can suggest relevant, self-contained moments using your examples and topic. It cannot guarantee views, watch time or follower growth.

Can I change the clips afterwards?

Yes. Review cut points, captions and crop settings, then render again. The handover includes subtitle files and source timestamps; native editing-project formats can be agreed separately.

Can it clip sports or visual-only footage?

Those need visual event understanding beyond this speech-led workflow. Agree different models, examples, acceptance tests and pricing with your provider.
