How to condense a long livestream into a watchable summary
Give Vizard Agent the stream and a target length. Vizard Agent transcribes the whole thing, writes a chronological breakdown minute by minute, cuts the silence and dead air, adds dynamic zooms onto your avatar at coordinates it measured, and test-renders a slice before committing to the full export.
What do you type into Vizard Agent?
Ask for a condensed version rather than highlights, and give a target length. Vizard Agent reads "condense" as an instruction to keep the chronology of the whole session and remove only the empty stretches. Asking for the best bits produces a different, far shorter video. Condensing to a third keeps the arc; condensing to a tenth makes a highlight reel.
Prompt
What does Vizard Agent actually do?
Condensing isn't clipping. A forty-minute stream cut to fifteen keeps the whole arc, every match, every conversation and the ending, and removes only the parts where nothing happens. Writing out what happens in each block first means the cuts land between events rather than through them. In the session behind this article it:
- Tried several times to download the stream, diagnosed the failures and worked from the uploaded file instead.
- Transcribed the audio with timings, built a frame grid across the whole stream and analysed the silences and dead time.
- Wrote a complete chronological breakdown summarising every block of minutes, then calculated the cut timings and verified the total duration.
- Located the avatar precisely, calculated its coordinates for the zooms and tested the zoom crop on a frame.
- Generated sound effects for the fails, rendered a thirty-second slice to check speed and quality, then rendered all thirty-seven segments and joined them: fifteen minutes and six seconds from a forty-two minute stream.
When does this not work well?
Condensing preserves a session's arc, so the result inherits whatever arc the session actually had. Vizard Agent removes dead air and tightens the pacing, but an aimless stream condenses into a shorter aimless one. Fifteen minutes still asks a lot: it works for an existing audience, not for discovery. Anything said on stream ends up in the summary.
Common questions
Is this the same as a highlight reel? No. A summary keeps the whole run in order; highlights keep the best moments and discard the arc.
How much can Vizard Agent condense? This run went from forty-two minutes to fifteen. Below about a quarter it stops being a summary and becomes highlights.
Why test-render thirty seconds first? Because a mistake in the caption position or the zoom crop is much cheaper to find in a thirty-second slice than after a fifteen-minute export.
