ffflow

A CLI and TUI for ffmpeg workflows. Define your encodes once in a .flw file, run them, and watch everything progress in real time.

No more retyping long ffmpeg commands or maintaining shell scripts for batch jobs. ffflow wraps the ffmpeg binary on your PATH -- it doesn't reimplement any encoders.

Install

cargo install --git https://github.com/yugaaank/ffflow

Or build from source:

git clone https://github.com/yugaaank/ffflow
cd ffflow
cargo build --release

You need a Rust toolchain and ffmpeg on your PATH.

Usage

Single encode

ffflow encode -i input.mov -o out.mp4 --vcodec libx264 --preset veryfast

Multiple inputs

ffflow encode -i a.mov -i b.mov -o merged.mp4 --extra-args "-filter_complex concat"

Probe a file

ffflow probe -i input.mov

Batch mode

Write a .flw file where each line is an ffflow encode command:

encode -i clip1.mov -o clip1.mp4 --preset fast
encode -i clip2.mov -o clip2.mp4 --preset fast
encode -i clip1.mp4 -i clip2.mp4 -o final.mp4 --extra-args "-c copy"

Then run it:

ffflow pipeline.flw

This opens the TUI with a live progress track per job. A summary shows when all jobs finish.

Presets

Built-in x264 presets: ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow, placebo.
