Summary

The development journal's post for 2.1: Off-Menu video editing, at /blog/off-menu-video-editing.

OpenScreen 2.1 introduces Off-Menu. The built-in functions stay. Next to them, a low-level layer lets a coding agent write the function the editor lacks, directly on the video, through the MCP tools and inside their guardrails. Visual effects are the first implementation. The post covers the concept, the prior art, the architecture, the measurements, what the contract learned, the limits, and where the idea goes next.

What it adds

  • website/blog/2026-10-17-off-menu-video-editing.mdx, dated to the 2.1 promotion, with slug: off-menu-video-editing so the URL does not depend on the date.
  • website/static/img/blog/off-menu/: the two figures (the render pipeline and the cost calibration) and the ripple clip with its poster.

To know before merging

  • The clip is the ripple from the first prompt. The water drop under the orbit camera, the better demo, is to be re-rendered on the release build and swapped in later; the post's text already describes it.
  • Merging publishes the post. The launch posts link to it on Tuesday; the post itself carries no date-sensitive promise beyond "2.1 is free and open source".

Related issue

None.

Type of change

  • Documentation

Release impact

  • No release note needed

Desktop impact

  • Not platform-specific

Screenshots / video

The clip is in the post.

Testing

  • The post compiles with the site's MDX 3 and remark-gfm, and every asset and docs link it uses exists (/docs/effects, /docs/ai-editing).
  • The full site build runs in CI (Docs).

Summary by CodeRabbit

  • Documentation
    • Added an article introducing OpenScreen 2.1’s Off-Menu approach, where coding agents create GPU effects with context and safeguards provided by the editor. The article covers how effects are previewed and exported, performance and consistency measurements, supported capabilities and limitations, and instructions for use. It also compares related tools and outlines possible future extensions.
