Remotion Video Plugin for DeepSeek Harness — prompt to verified MP4

[chenjie1129]

I built an independent open-source plugin that adds a remotion-video skill to DeepSeek Harness. It gives the agent a preview-first workflow for inspecting a project, writing frame-driven React animation, checking representative stills, and rendering verified video output.

The 12-second demo is a real Remotion render included with its source:

• H.264, 1280×720, 30 fps
• animations use useCurrentFrame(), interpolate(), and Sequence
• local assets only; no credentials, telemetry, or remote service calls
• ESLint, TypeScript, dependency audits, package tests, and isolated Harness smoke tests pass

Watch the MP4 and inspect the source: https://github.com/chenjie1129/remotion-video-plugin

Release: https://github.com/chenjie1129/remotion-video-plugin/releases/tag/v0.1.0

The plugin is a community project and is not affiliated with the Remotion team. I would especially welcome feedback on the workflow boundaries, preview checks, and example prompts.
