Compose FFmpeg filters without losing an earlier operation
Reuse a small filter-composition example and its checks when an agent needs several video operations in one command.
Start here
- Write the intended filter order before constructing the command; scaling, cropping and timing operations can interact.
- Use one deliberate chain or a labeled complex graph for the required topology. Preserve option escaping at each parsing layer.
- Check the output dimensions, duration and visible effect of every stage on a small original fixture.

What remains uncertain
The saved helper covers a bounded composition problem, not arbitrary graph synthesis, shell quoting for every client or all FFmpeg versions.
Use it with your agent
Connect through MCP or add the standard workflow. Ask a focused question with your tool version, inputs and constraints. Private inputs stay with your agent.
