HOW TO — 3 / 6

Open and fix

The AI's first cut arrives almost finished. Your job is to open it and fix anything that needs attention. There are three ways: drag to move, double-click to edit text, or ask in words. All changes appear immediately.

1 — How to open it

Open in your browser or the app

There are two places to view your edit. Both read the same save data (edit.json), so their content stays in sync.

🌐 Browser preview

The easiest option. Enough for review and minor fixes.

akari.sh --preview

Run the command, then open http://localhost:4567 in your browser. You can play the video, drag telops to adjust them, and change cut values numerically.

🖥 Desktop app (macOS / Windows, Public Beta)

The main editing interface. Use the timeline and inspector for detailed adjustments.

Install from the download page. Use the app for a multitrack timeline, layer editing, and subtitle styling. Its three-pane layout puts footage on the left, your Partner (相棒), the AI chat, on the right, and the result in the center.

2 — Three ways to make fixes

Edit by hand or ask in words

Drag to move

Grab a telop or shape and move it where you want. Adjust timing by dragging the ends of its bar to extend or shorten it.

Double-click to edit text

Double-click a typo in a telop and retype it in place. Adjustable values such as fonts and colors automatically get controls for each asset, including sliders and color pickers.

Ask in words

For changes to the structure, asking the AI is faster:

YouMake the second telop appear one second later.
YouTurn the music down a little. It is hard to hear the speech.
YouTighten up the opening cut.

3 — Where your changes are saved

Every change writes back to the save data

Whether you drag, double-click, or ask the AI, every change goes to the same place: the project's edit.json, the editing source of truth. This means:

Closing the window does not lose your work. Pick up where you left off next time
The browser and app stay in sync. Both read the same file
You can track what changed and when. All edits are recorded as file diffs

The preview and finished output look the same. The system is designed and tested to ensure the exported MP4 matches the preview, using the same assets and rendering contract.
