render.status
The render bar of a sequence (Premiere's red/yellow/green bar): segments between edit points, each "red" (must be rendered to play in real time: nested sequences, adjustment layers or effects heavier than real time), "yellow" (effects, transitions, blend modes or track mattes that may play in real time), "rendered" (a valid preview file exists) or "none" (plays as it is).

The render bar of a sequence (Premiere's red/yellow/green bar): segments between edit points, each "red" (must be rendered to play in real time: nested sequences, adjustment layers or effects heavier than real time), "yellow" (effects, transitions, blend modes or track mattes that may play in real time), "rendered" (a valid preview file exists) or "none" (plays as it is). Rendered segments show only in hosts with a preview cache.
Run it with wabcut-cli cmd <project> --json, from an MCP client as render_status, or from an extension. See Edit commands for requests, references and results.

- render.deletePreviewFiles
Delete Render Files. Deletes preview files: of the sequence between "start" and "end" (In to Out with Sequence > Delete Render Files In to Out), of the whole sequence, or with "all" of every sequence in the project.
- render.previewInOut
Render In to Out. Renders preview files for the red and yellow segments between In and Out (or "start" / "end"; else the whole sequence), so they play in real time; segments with a valid preview are skipped.
