How AI video highlight detection works

Postmixr transcribes your video, detects scene cuts, samples key frames, and uses vision AI to understand on-screen action. A ranking model picks the best non-overlapping moments with titles, scores, and reasons.

You get full transparency: browse transcript, scenes, and vision tabs before exporting timestamps.

Timestamps, JSON, CSV, and YouTube chapters

Copy individual time ranges, download highlights.json or highlights.csv, or use chapter-style text for YouTube descriptions. When you are ready to render vertical clips, send the same job to our Auto Shorts generator.

FAQ

How does AI find highlights in a video?

We transcribe speech, detect scene cuts, sample key frames with vision AI, then rank the strongest non-overlapping moments with titles and timestamps.

Can I extract highlights from a YouTube video?

Yes. Paste a public YouTube, TikTok, or Instagram link, or upload a file directly.

Do I get video clips or timestamps?

Timestamps only in v1: copy ranges, export JSON/CSV, or send highlights to the Auto Shorts generator to render clips.

How many highlights will it find?

You choose up to 3, 5, or 10. Each clip respects your minimum length setting (15–60 seconds).

Is there a length limit?

Free tier supports videos up to 30 minutes.

How is this different from Opus Clip?

We show the full analysis (transcript, scenes, vision, and ranked highlights) before you render shorts. No black-box clip output only.
