Guide
How agents work
Everything you need to build your own agent: how steps connect, in what order they run, what a run costs, and every step explained.
The idea
An agent is the way you edit, written down as steps. Your video goes in at the start, every step does one job, and the finished video comes out at the end. Once it's built, it edits every new video the same way.
Everything runs in your browser. Your video is never uploaded: only the sound, the text and single frames go to the AI, and only for the steps that need it.
Steps and connections
Every box on the canvas is a step. Inputs sit on the left and top edge, outputs on the right and bottom. Drag from an output to an input to connect two steps: the wire carries what one step hands to the next.
Only ports of the same kind connect, and the color tells you the kind. An input takes one wire; an output can feed as many steps as you like.
What travels along a wire
- Video The recording itself. Transcribe reads it.
- Timeline The edit so far. It runs through almost every step, and each one adds its part.
- Transcript Your words with their times, from Transcribe. Every step that reads what you say needs it.
- Files Extra files you pick when the agent runs: B-roll, music, an external mic.
- Audio The cleaned sound from Studio Sound, for the Audio File output.
- Style A look (colors, fonts, motion) for the steps that design something.
- Plan Lumi Architect's plan for the whole edit. Lumi Builder carries it out.
- Notes Your notes from a Review, sent back to an earlier step.
Start and end
Every agent starts with the Video node and ends with at least one Render Video. Neither can be deleted. In between, the timeline runs as a chain from step to step.
Add more outputs when you want files besides the MP4: a project file for DaVinci Resolve, Premiere or Final Cut, captions, the audio, a chapter list.
In what order steps run
Steps run one after another along the wires: a step starts once everything it needs has arrived. Order matters. Autocut before Subtitles means the subtitles fit the cut video.
A step that leads to no output doesn't run, and the editor warns you. A step whose inputs stay empty, for example after a Condition took the other path, is skipped, and so is everything that depends on it.
A good order for most videos: Transcribe and Autocut first, then sound, then zooms and layouts, then text and graphics, the outputs last.
Branches, merges and reviews
- Condition Sends the timeline down Yes or No: by the video's length, its language, or a yes/no question the AI answers about what is said.
- Merge Joins two paths again and passes on whichever one ran, so both paths can lead to the same render.
- Review Pauses the run so you can look. Approve, and it goes on. Write what to change, and your notes travel back along Revise to an earlier step with a Notes input; that step and everything after it run again.
Running an agent
- 1Click Run and pick your video, plus any files the agent asks for.
- 2Check the price. Nothing is charged before you start, and local steps are free.
- 3Watch every step live. Keep the tab open; it may sit in the background.
- 4When a Review pauses the run, approve it or send it back with notes.
- 5At the end the edit opens as a project in the editor, and every output is ready to download. If the page reloads, you can continue where it stopped without paying again for finished steps.
What it costs
Steps marked Local run on your computer and are always free. Steps marked AI use credits: the price depends on the video's length, the model you pick and the thinking depth.
In the editor, the coin button estimates the price for videos from 5 to 60 minutes. The run page shows the exact price before you start. If an AI step fails, you get its credits back.
The prices in the step list below are for a 10-minute video with the default settings.
Let Lumi build it
You don't have to wire it yourself. Describe how you edit, and Lumi builds the agent. In the editor, Lumi sits in a tab next to the steps: chatting is free, building and checking cost credits and show the price first. Every change comes as a suggestion you apply or leave.
Send Lumi a link to your YouTube channel, and it learns your style from your newest videos.
Start from a template
Lumenwerk's agents are a good start. Use one as it is, or duplicate it and change any step.
- Lumi Full EditWhat Lumi does: cleans the recording, plans the whole edit in your style and builds it, graphics included.
- Approve the PlanLumi plans the edit and waits for you: approve it, or say what to change and Lumi plans again before anything is built.
- Quick CleanPauses and fillers out, studio sound, subtitles on. Also writes the SRT for YouTube.
- Talking Head PolishA tight cut with zooms on the key words, chapter titles and keywords on screen, and sound effects where the picture changes.
- Podcast to YouTubeTurns a podcast recording into a YouTube episode: a gentle cut that keeps the conversation, even sound, chapters, subtitles, and the audio, SRT and chapter list as files.
- Tutorial / Screen RecordingFor screen recordings: idle stretches sped up, zooms where you explain, chapters on screen and as a list for the description.
All steps
Every step with what it needs, what it gives, its settings and where it belongs in an agent.
