# lazyff
|
||
|
||
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.
