Audio tracks
Set each track's volume and pan, and use mute and solo (hear only this track) to listen selectively. The ducking (lower while speaking) effect follows the speech on tracks with the 'Voice' role.
Master
Applied after all sound is mixed, the same in the preview and the export.
Match loudness

While playing
Export the scene shown in the preview. Your media stays on your device.
Hide or restore areas on the full picture before transforms. Hidden areas appear faint here. The brush and shape masks apply together. Original media stays unchanged.
Size is relative to the shorter picture edge. The mask moves and transforms with the picture.
Drag to choose the area to keep. The result is saved as a new asset and this clip switches to it. The original asset is kept.

WebGPU is not available on this device, so recognition runs on the CPU and may be slow.

Find visible elements and scenes. Update the index before searching. Analysis is manual. Audio and sounds can also be found and previewed by interval.
Find assets by what pictures and videos show, or by speech and sounds. Google's EmbeddingGemma 2 model (Apache 2.0 license) and its runtime are downloaded once from the AGONECO mirror (or the original source) into the app folder, and every file is checked with SHA-256. Pictures, videos and audio are analysed only on this device and are never sent anywhere.
Starting embedding analyses every asset not analysed yet and, from then on, each asset you add. Then search with the AI search button in the search field or Enter.
AI search mode — on, new pictures, videos and audio are analysed (embedded) automatically in the background and AI search and scene search work; off, nothing is embedded on this device and resources are saved.
Pictures and frames analysed per model run (1–16)

Subtitle times are divided by the speed, then the offset is added. Use the same speed you applied to the video or audio.
For example, 2× speed halves subtitle times. A negative offset makes subtitles appear earlier.
AGONECO Video Editor is a multitrack editing tool that runs in your browser without an app installation.
Imported media is not uploaded to a server for editing. Automatic backups are stored in this browser. The conversion engine and fonts are downloaded from a CDN on first use.
AI agents such as Claude Code or Codex can write a project for this editor as JSON and hand you a link. The format is fully documented in https://tools.agoneco.com/agents.md, so no sample link is needed. Link format: https://tools.agoneco.com/edit/#json= followed by the URL-encoded project JSON. Example: {"layers":[{"src":"A.png","effects":[{"start":0,"end":1,"effect":"enter"},{"start":1,"end":3,"effect":"float"}]}]}
