built for agents.
Agent Effects turns a YAML project into video. It renders each frame in native Rust, so it does not need browser screenshots or new code for every video.

The pipeline
Videos stay data.
The engine stays compiled.
Agents build scenes from clear, named parts. They can check the project and inspect still frames before they render the full video.
-
01
Describe
Write the story, scenes, layouts, and timing in one readable
.afx.yamlproject. -
02
Validate
Find broken timing, missing assets, and invalid scene settings before you render the video.
-
03
Inspect
Render one frame, a contact sheet, or a quick preview. Check what the video looks like, not only the source file.
-
04
Render
Send CPU or Vulkan frames straight to FFmpeg without holding the whole video in memory.
Current capabilities
A focused visual language
with strong defaults.
Agents can start with ready-made layouts and animation presets. They can also use layers and keyframes when they need exact control.
AUTHORING
02
Built for agents to explore
The CLI includes help, a full schema, searchable examples, named presets, and error messages that explain how to fix a problem.
03
See problems early
Render single frames, contact sheets, and quick previews. The CLI can also review a project and open a local review screen.
04
Fast native rendering
Get repeatable CPU output or use Vulkan on a supported GPU. Frames stream straight to FFmpeg.
Quick start
From zero to first frame.
Clone the source, create a project, check it, and render one still frame before you make the full video.
