Turn One Long Video Into Short-Form Clips

Drop in a podcast, a talk or a stream. Katama reads the transcript, picks the moments that actually hold attention, and writes the titles and captions for each one.

What it is

Most long videos contain three or four minutes worth watching and fifty that nobody will. Viral Creator finds them. It transcribes your source, scores every moment against the patterns that keep people watching — an open loop in the first two seconds, a number with a consequence, a named mistake — and returns a cut list with exact timestamps, plus the title, caption and hashtags for each clip. You keep every editorial decision; it removes the two hours of scrubbing that come before them.

How it works

  1. 01

    Add the long video

    A podcast episode, a webinar, a stream, an interview — anything with someone talking.

  2. 02

    Katama reads it and picks the moments

    You get 3-5 clips with exact start and end timestamps, each with the reason it was chosen. No invented timestamps — every one comes from the transcript.

  3. 03

    Cut, caption, publish

    Take the cut list into the caption tool to burn in subtitles, then schedule the posts. Titles, captions and hashtags are already written in the speaker's own words.

Why creators choose it

Timestamps taken from the transcript, never invented
Clips scored on the hook, not on vibes
Titles and captions in the speaker's own voice
Fewer, better clips — 3-5, not 30

Frequently asked

Does it cut the video for me?

It gives you the exact cut list — start and end timestamps for every clip, with the hook line quoted from the transcript. Burning in subtitles and rendering runs through the caption tool, which handles long re-encodes properly.

Why only 3-5 clips?

Because most long videos honestly contain 3-5 moments worth posting. A tool that returns 30 clips is padding the list, and every padded clip costs you a render and a post that nobody watches.

What makes a moment worth cutting?

One rule: the first two seconds have to open a loop. A brilliant explanation that starts with 'so, um, basically' is a bad clip — the same explanation starting where the stake is named is a good one.

Will the captions sound like marketing copy?

No. They are written from the speaker's own words in the transcript. The reason short-form works is that it sounds like a person, and smoothing that away is the fastest way to lose the audience.
