How to add laugh tracks and comedy music to a video
Give Vizard Agent the video and ask for laugh tracks and comedy music on the funny moments. Vizard Agent transcribes the audio to word-level timings, reads the frames to see what is actually happening, finds the exact second each joke lands, and places the laugh and the sting on that word rather than on a guess.
What do you type into Vizard Agent?
Say what treatment you want and how long the pieces should be. Vizard Agent works out where the jokes are from the transcript and the frames, so the useful instruction is about the finish rather than the moments. Say what kind of comedy it is too, because studio sitcom, meme energy or deadpan decides which laughs get used.
Prompt
What does Vizard Agent actually do?
It never estimates a timestamp. It searches the word-level transcript for the word that starts and ends each joke and cuts to those numbers. That matters because comedy timing is the whole job: a laugh that fires half a second late reads as a mistake. In the session behind this article it:
- Downloaded the video, probed its length and specs, and extracted the audio as a small file so it would upload and transcribe faster than the video.
- Ran word-level transcription to find the jokes and the moment each landed, and looked at extracted frames to see the expressions and what each joke was about.
- Searched the sound library for comedy music and studio-audience laughs.
- Trimmed the word-timing file to each clip's range with a small script, searched it for the keyword that opens the joke and the one that opens the next, and re-cut the clip to those exact numbers.
- Listed the system's font families before burning any text, then rendered one test frame and looked at it before the full render.
- Delivered a vertical 1080x1920 clip of exactly 30.0 seconds, cut from a much longer source, with music, laughs and animated captions burned in.
When does this not work well?
A laugh track is an opinion about what is funny, and precision is not the same as being right about whether a line deserved a laugh. A laugh on a line that isn't funny is painful, so ask for them sparse. Overlapping dialogue blurs the transcript and the placement, and a busy music bed can still bury a quiet punchline.
Common questions
Does it choose the funny moments itself? Yes. Vizard Agent reads the transcript and looks at the frames. You can name a moment too.
Can it make several clips from one long video? Yes, and it's cheaper than one at a time, because Vizard Agent does the transcript once.
Can I have music without the laugh track? Yes. Say so, and Vizard Agent scores the cut without the audience.
