Your agents can process video at scale. No FFmpeg infrastructure to manage.

Go to renderio.dev/get-api-key and generate a free OAuth token.

Hermes runs via Ollama or LangGraph. Use an MCP client library (e.g. mcp-python, LangGraph MCP tools) to connect the RenderIO server and expose it as callable tools to the model.

  "renderio": {

  }
}

Hermes calls run_ffmpeg_command with structured parameters. The server validates placeholder syntax and key prefixes before FFmpeg runs — malformed calls return typed errors Hermes can fix on retry.

Double-brace placeholders

The ffmpeg_command field uses {{key}} syntax. Single braces fail server-side validation before the sandbox ever runs.

Key prefix convention

All input_files keys must start with in_, all output_files keys with out_. Validated at the MCP layer.

Every key must appear in the command

Unused keys and missing placeholders both fail. The schema check catches this before FFmpeg runs.

Status values are uppercase

When calling get_command, always compare status as uppercase strings.

Output URL location

Each output file is an object with storage_url, filename, size_mbytes, and optionally duration, codec, width, height.
