A friendly terminal UI for FFmpeg. Trim, resize, crop, compress, convert and
apply effects to video and audio — without memorizing a single flag.

lazyff always shows the exact `ffmpeg` command it is about to run, so you can
learn FFmpeg as you use it (and copy-paste the command anywhere).

## Requirements

- `ffmpeg` and `ffprobe` on your PATH
- A terminal

## Install / run

```sh
cargo run --release
# or
cargo install --path .
lazyff
```

lazyff opens a file browser in the current directory. Pick a video or audio
file, then stack up edits and press `r`.

## What it can do

| Edit            | Examples                                              |
| --------------- | ----------------------------------------------------- |
| Trim / Cut      | keep 0:30 → 1:45, instant lossless stream copy        |
| Resize          | 1080p/720p/480p presets, half size, custom            |
| Crop            | centered square / 16:9 / 9:16 / 4:3, custom rectangle |
| Rotate / Flip   | 90°, 180°, mirror                                     |
| Speed           | 0.25x – 4x, audio pitch preserved                     |
| Color adjust    | brightness, contrast, saturation                      |
| Visual effects  | grayscale, sepia, blur, sharpen, vignette, denoise, fades |
| Frame rate      | 12 – 60 fps                                           |
| Compress        | H.264/H.265 with plain-English quality presets        |
| Convert format  | MP4, MKV, WebM, MOV, GIF (with palette pass), MP3, M4A, WAV |
| Audio           | remove track, volume, loudness normalization          |

Edits combine: add a trim, a resize and a compress, and lazyff builds one
ffmpeg command that does all three in a single pass.

Audio files (MP3, FLAC, WAV, ...) only offer the edits that make sense for
them — trim, speed, volume/fades, and conversion between audio formats
(MP3, M4A, FLAC, WAV, OGG).

## Keys

**File browser** — `↑↓` move, `Enter` open, `Backspace` parent folder, `q` quit

**Editor** — `a` add edit, `Enter` change, `d` delete, `J`/`K` reorder,
`o` output name, `r` run, `Esc` back to files, `q` quit

**Forms** — `↑↓` field, `←→` change choice, type into text fields,
`Enter` save, `Esc` cancel

While encoding you get a progress bar with speed readout; `Esc` cancels and
removes the partial output. Output files are written next to the input as
`<name>_lazyff.<ext>` (rename with `o`); lazyff refuses to overwrite the
input file.
