Motion Render Ops

Use this skill to drive the actual render: resolving the storyboard, expanding targets, running pre-render checks, executing the render, and persisting manifests.

Read ../../references/render-config.md and ../../references/channel-targets.md before running a render.

Use when

• A validated storyboard is ready to render.
• A previous render needs to be reproduced or extended to new channels.
• An asset or recipe version changed and the artifact must be regenerated.

Do not use when

• The storyboard is not validated. Use motion-storyboard first.
• The failure is a QC issue, not a render issue. Use motion-qc.
• The brief asks to invent new scenes during render time. That is a guardrail violation.

Render-ops failures to avoid

• starting render without resolving asset references
• skipping the pre-render hook
• running a render without a stored seed for any random behavior
• failing to record render config alongside the output
• silently truncating audio or captions when scene length conflicts with audio length

Workflow

1. Resolve the storyboard

Validate against the storyboard contract. Reject invalid storyboards.

2. Expand targets

Build a render config per target with aspect, duration, caption layout, cover frame, codec, and bitrate.

3. Run pre-render checks

Run the pre-render hook or its in-skill equivalent: duration, asset presence, caption coverage, cover frame, export spec.

4. Execute the render

Use the configured code-driven motion runtime, default remotion. Persist the render config alongside the output.

5. Generate post-render artifacts

Produce a contact sheet and a render manifest with scene-level metadata and asset references.

6. Surface failures with rerun guidance

When a scene fails, persist scene-level diagnostics and a rerun suggestion.

Output format

Return:

1. Storyboard summary

• id, version, target count, scene count

2. Render plan

• per-target render config summary

3. Pre-render check result

• pass list and any blocking failures

4. Render result

• per-target output path, status, duration

5. Post-render artifacts

• contact sheet path and manifest path per target

6. Failure follow-up

• failed scenes, suggested rerun, asset or config gaps

Use together with

• motion-storyboard
• motion-scene-builder
• motion-qc
