Features

Multi-Signal Moment Scoring

Each second of a video receives a composite score based on audio energy peaks, motion intensity, and speech semantic density. Segments scoring above 65 surface as clip candidates, ranked by estimated TikTok completion rate.

Hook and Endpoint Detection

AutoClip identifies the strongest visual and audio hook at the start of each candidate clip and suggests the natural endpoint — where the reaction lands, the play concludes, or the punchline completes.

One-Click 9:16 Reframe

Converts landscape YouTube footage to portrait format with subject tracking. The reframe follows the action center — face, ball, reaction — and keeps it in frame throughout the clip.

Punch-In Zoom Editor

Apply a targeted zoom at the peak moment of any clip. Mark the key frame, set the zoom level (recommended 10–15%), and AutoClip renders the punch-in effect into the final export.

How It Works

1

Paste the video URL

Enter any public YouTube video URL into AutoClip. Works with videos up to 4 hours in length.

2

AI scans and scores every segment

AutoClip processes audio, motion, and transcript in parallel. A 60-minute video typically yields 8–15 scored candidate clips in under 3 minutes.

3

Review and trim candidates

Browse ranked clip candidates, adjust start and end points using the trim editor, and discard any that don't meet your hook and completion standards.

4

Reframe and punch-in

Apply 9:16 reframe and optional punch-in zoom to your selected clips. Preview before export to verify the crop and zoom are centered on the action.

5

Export and post

Download at 1080x1920 for TikTok, Reels, or Shorts. AutoClip retains the original audio and applies captions if enabled.

Frequently Asked Questions

What video length does the viral moment finder work with?

Any public YouTube video up to 4 hours. The analysis time scales with length — a 60-minute video takes under 3 minutes, a 3-hour stream takes 10–12 minutes. Most clippers target 20–90 minute videos since they have the highest viral-moment density per hour of content.

How is this different from just watching the video myself?

Watching a 60-minute video to manually find 3–5 clippable moments takes 20–40 minutes. AutoClip surfaces the same candidates in under 3 minutes. The AI won't catch context-dependent humor from running jokes, but it accurately identifies high-energy moments, strong opinion statements, and physical events — which covers 90% of what makes clips go viral.

Can I use this on any YouTube channel?

Any public YouTube video. Works on gaming channels, podcasts, interviews, sports highlights, reaction channels, commentary, and live stream VODs. Content ID risk varies by channel — AutoClip's scoring doesn't filter for Content ID exposure, so check each channel's claim history before building a full clip operation around it.
