vedit-0.1.1 is not a library.

vedit

vedit is a small Rust command-line wrapper that runs auto-editor to remove silent parts from a video and then uses ffmpeg to adjust playback speed.

It automates the two-step process: run auto-editor with a configurable margin, then apply video and audio speed filters with ffmpeg.

This tool expects auto-editor and ffmpeg to be available on your PATH.

Requirements

Rust (stable) — to build the project
auto-editor — installed and available on your PATH
ffmpeg — installed and available on your PATH

Note: vedit assumes that after running: auto-editor <input> --margin <N>sec, an altered file will exist with the same stem as the input and the suffix _ALTERED (e.g. video.mp4 -> video_ALTERED.mp4).

Building

From cargo:

cargo install vedit

From the project root:

# Build in release mode, binary will be in ~/.cargo/bin
cargo install --path .

Usage

Basic invocation:

vedit <input> --margin <seconds> --speed <factor> --output <output>

Arguments:

<input> — Path to the input video file (positional).
--margin — Margin in seconds passed to auto-editor (float, e.g. 0.2).
--speed — Playback speed factor applied with ffmpeg (float, e.g. 1.25, 1.5, 2.0).
--output — Output filename for the final processed video.

Example:

# Remove silent parts (with 0.2s margin) then speed playback 1.5x, writing to output.mp4
vedit input.mp4 --margin 0.2 --speed 1.5 --output output.mp4

How it works

The CLI performs the following steps:

Parses arguments.
Runs:
- auto-editor <input> --margin <margin>sec
- Expects an altered file named <stem>_ALTERED.<ext> to exist after that command.
Runs ffmpeg on the altered file to change speed:
- Video filter: setpts=PTS/<speed>
- Audio filter: atempo=<speed>
Writes the final file to the path provided by --output.

The code returns errors when the external commands exit with non-zero status:

If auto-editor fails, the program reports auto-editor failed.
If ffmpeg fails, the program reports ffmpeg failed.
