Turn long videos into ranked, ready-to-post clips.

A video clipping API turns a long video or a live stream into short, ranked, captioned clips through REST calls instead of an editor. You send a source ID and a genre, the agent scores every candidate moment, and a clip.ready webhook returns each clip already reframed for 9:16, 1:1, 4:5 and 16:9. No dashboard sits in the loop unless you want one there.

Use a clipping app when clipping is the whole job, and a clipping API when clips are one feature inside a product you are shipping. Apps stop at export: the clip still has to be stored, encoded, delivered, played and measured somewhere else. FastPix runs clipping on the platform that already does all five, so the clip never leaves the stack and never shows up as a second vendor on the bill.

You clip a live stream mid-broadcast by calling the clipping endpoint with a timecode range while the stream is still running. FastPix returns a playback-ready clip about 12 seconds after the producer's cut, so a goal, a quote or a product drop reaches social while the moment still matters. There is no waiting for the stream to finish and convert to VOD.

Highlights can publish automatically within minutes of a stream ending, with no manual step in between. The agent ranks clips as the stream closes, your brand template is applied at render, and approved clips post to TikTok, YouTube Shorts, Reels, X and Facebook on the schedule you set. Teams that want a person in the loop route clips to a review dashboard first, and approval is one click.

FastPix transcribes and captions conversations that switch between two languages mid-sentence, which most clipping tools render as nonsense. Hinglish, Spanglish, Taglish and Arabic-English speech are handled with transliteration, so the caption reads the way the sentence was actually spoken instead of being forced into one language or machine-translated into both. Clips carry captions in 50+ languages, applied at compose time.

Every candidate moment is scored on five signals before a single clip is cut, and the ranked list is what you start from. Contextual asks whether the clip stands on its own. Hook measures first-second strength. Action measures the density of meaningful events. Intensity measures energy and emotional arc. Narrative measures story completeness. The weights change by genre, so a sports clip and a lecture clip are never judged by the same rules.

Clipping is tuned per genre rather than assuming every video is a podcast, which is where single-genre tools break. Podcasts, webinars and online courses, comedy, vlogs, gaming, sports including basketball and NFL, news, movies and travel each ship with their own CHAIN weights. Custom weights can be set per account for a genre that is not on the list.

Each creator on your platform gets their own brand template, applied automatically at render with no per-creator work from your team. A template carries the watermark, font, intro card and sponsor overlay, and attaches by ID on the clipping call. Superbit runs 40 creator brands this way today. There is no per-creator rendering engine for you to build or maintain.

Clipping runs as a webhook-driven step inside n8n, Zapier or your own job queue, with no dashboard involved. A clip request returns immediately, the clip.ready webhook fires when output is available, and each clip arrives with its CHAIN score so your workflow can auto-publish above a threshold and route the rest to review.
