## The Challenge of Finding Viral Moments

Every long-form video contains a handful of moments that resonate with audiences — emotional peaks, surprising revelations, powerful statements, or perfectly timed humor. Traditionally, finding these moments meant watching hours of footage manually.

ClipForge's AI Clip Detection changes that by reading the whole conversation for you and handing back a ranked shortlist of the clips most likely to stand on their own.

## How Clip Detection Works

### 1. Transcription

The video is transcribed first, and every line of the transcript carries a timestamp. Those timestamps are what make a suggested clip start and end on the right words.

### 2. Reading the Whole Transcript

Claude reads the full timestamped transcript and picks the passages worth cutting: emotional peaks such as conflict, surprise, inspiration or humor, strong opening hooks, stories that resolve, and quotable statements that make sense without the rest of the video. It works from the words, including cues such as [laughter] where the transcript records them. It does not measure audio levels or analyze the picture.

### 3. Virality Score and Reason

Each pick comes back with a title, a 0-100 virality score and a sentence explaining why it was chosen. Clips are ranked by score so you can start with the strongest candidates. On request, a breakdown scores a clip on hook strength, emotional peak, pacing, standalone value and trending alignment.

### 4. Your Review and Trim

Detection produces a shortlist, not a finished set. You review each suggestion, keep or drop it, and trim the start and end before export.

## From Detection to Distribution

Once clips are identified, ClipForge handles the rest of the pipeline: a center crop to 9:16 vertical format, auto-generated captions in three styles, and batch export with each clip at the aspect ratio set on it. The entire workflow — from upload to export-ready clips — typically completes in minutes rather than hours.

## Frequently asked questions

### How does AI clip detection work?

In ClipForge it starts with the transcript. The video is transcribed with timestamps, and Claude reads the whole transcript to pick the passages with emotional peaks, strong hooks, complete stories and standalone value. Each pick comes back with start and end times, a 0-100 virality score and a sentence explaining why it was chosen, and the list is ranked by score.

### Why does ClipForge detect clips from the transcript?

Because what a clip says decides whether it stands on its own, and the transcript carries what was said with exact timestamps for the cut. It also records cues such as [laughter] or applause where the transcription captures them. What it cannot carry is tone of voice or what is on screen, so a moment that lands only through delivery or a visual can be missed. That is one reason every suggestion goes to you for review.

### Does AI clip detection replace human review?

No. Detection produces a ranked set of candidates, not a finished set of clips. The ranking decides what you review first, which is where the time saving comes from, but the judgment about which clips fit your audience and positioning stays with you. Treat the output as a shortlist rather than a decision.

### What is a virality score?

A 0-100 number Claude gives each clip it picks from the transcript, with a sentence saying why. It ranks clips against each other so you can prioritise. It is a relative ranking rather than a prediction: a high score means this clip is the strongest candidate in this video, not that it will go viral.
