Render the shared composition with aerender in the background and put the movie in the Switch library. The project must be saved. Poll aftereffects_edit_status until done; result.assetId is the library asset every other Switch tool can use. Start with a short range (a 3 second draft) before a full render. Times are whole composition frames; read frameRate and durationFrames first. Supply projectId, compId and revision from a fresh read. One operation per request; use the same requestId for retries. Queued does not mean edited: only a done status means After Effects reported a verified readback. Nothing is charged.
