A work in progress web tool to explore FFmpeg. Please log issues/suggestions. Made with svelte, xyflow, and ffmpeg.wasm.

Contributions are welcome! Take a look at the todo list below if you'd like to add a new feature, or the issues page if you want to try to fix a bug.

To run in dev mode:

npm install
npm run dev

I'm also looking for good FFmpeg examples. If you make a nice filtergraph in the tool, just hit cmd-s (or ctrl-s on windows/linux), and it will export a json file of your graph. Feel free to post those to the issues page for possible inclusion in the tool.

• Rendering on chrome doesn't work in multi-threading mode (it seems to fail on mp4s)

• Rendering progress bar
• "Cancel Render" button
• Disable/enable filters without removing them
• Deal with duplicate parameters in filters (sometimes filters have a long and short option)
• Add more help/documentation in the filters (there is more on FFmpeg's site that I could incorporate)
• Add input options like seek and trim
• Somehow figure out how to deal with complex filtergraphs
• Add more sample inputs (at least need an image and an audio file)
• Put filter options in a separate panel
• Add filters that generate content
• Handle audio and image output.
• Allow command to be editable
• Use commas to separate filters when possible
• Include some default fonts so text works.
• Allow gif as output
• Add more tests!
• MAYBE allow users to upload their own videos
• MAYBE make each part of the output command clickable, to highlight the corresponding nodes
• MAYBE add previews in the filter list itself

• ffmpeg.guide
• ffmpeg.app
• this nice screenshot
