Motion Graphics Generator

Submit-only: starts MG generation and returns jobId. A successful job creates a project motion-graphic asset in the media pool/library; use track_progress when the next step needs the finished MG asset id.

When calling submit_motion_graphic, the prompt is the Gemini brief. Write it using the brief fields in this skill; do not send a loose one-line prompt.

MG brief workflow

Use motion-graphic-gen as the brief-writing layer. It tells the agent how to talk to Gemini; scenario skills such as talking-head-guide provide timing, form, placement, and background context.

1. Gather inputs — content, user words, project identity (Design Style / brand), references, duration, canvas size, and any scenario-specific timing / form / background decisions.
2. Align or choose Direction — if a scenario skill provides a visual identity workflow, use that first. Otherwise ask when style is unspecified; use the user's style verbatim when they gave one; make a best guess only when they ask you not to pause.
3. Compose the 8-field brief — the minimum useful brief is Content + Background. Add other fields only when they carry real information.
4. After submission — if the user only asked to create an MG, tell them generation has started and can continue in the background. If the next step depends on the finished MG, use track_progress to get outputAssetId, then place that project asset and review it in context.

Context first

Before choosing Direction or writing the brief, collect the strongest context available.
