**Auto-Editor** is a command line application for automatically **editing video and audio** by analyzing a variety of methods, most notably audio loudness. --- [![Discord](https://img.shields.io/badge/Discord-Join%20server-5865F2?style=flat&logo=discord&logoColor=white)](https://basswood.io/discord) [![Nim](https://img.shields.io/badge/nim-%23FFE953.svg?style=flat&logo=nim&logoColor=black)](https://nim-lang.org) Before doing the real editing, you first cut out the "dead space" which is typically silence. This is known as a "first pass". Cutting these is a boring task, especially if the video is very long. ``` auto-editor path/to/your/video.mp4 ```

Cutting

Change the **pace** of the edited video by using `--margin`. `--margin` adds in some "silent" sections to make the editing feel nicer. ``` # Add 0.2 seconds of padding before and after to make the edit nicer. # `0.2s` is the default value for `--margin` auto-editor example.mp4 --margin 0.2sec # Add 0.3 seconds of padding before, 1.5 seconds after auto-editor example.mp4 --margin 0.3s,1.5sec ``` ### Methods for Making Automatic Cuts The `--edit` option is how auto-editor makes automated cuts. For example, edit out motionlessness in a video by setting `--edit motion`. ``` # cut out sections where the total motion is less than 2%. auto-editor example.mp4 --edit motion:threshold=0.02 # `--edit audio:threshold=0.04,stream=all` is used by defaut. auto-editor example.mp4 # Different tracks can be set with different attribute. auto-editor multi-track.mov --edit "(or audio:stream=0 audio:threshold=10%,stream=1)" ``` Different editing methods can be used together. ``` # 'threshold' is always the first argument for edit-method objects auto-editor example.mp4 --edit "(or audio:0.03 motion:0.06)" ``` You can also use `dB` unit, a volume unit familiar to video-editors (case-sensitive): ``` auto-editor example.mp4 --edit audio:-19dB auto-editor example.mp4 --edit audio:-7dB auto-editor example.mp4 --edit motion:-19dB ``` ### Labels Every moment gets an integer **label**: `0` is silent (cut by default), `1` is active (kept). `--edit` sets what's label `1`; `-w:0`/`-w:1` set each one's action. Add more classes with `--edit:N` and `--when:N` (`N` up to 255); where they overlap, the higher label wins. ``` # Cut silence, keep speech, and additionally speed up the loud parts auto-editor example.mp4 --edit:2 audio:-12dB --when:2 speed:1.5 ``` As a value (not a label), `--edit 1` keeps everything and `--edit 0` cuts everything. See the [actions docs](https://auto-editor.com/docs/actions) for more. ### See What Auto-Editor Cuts Out To export what auto-editor normally cuts out. Set `--when-active` to `cut` and `--when-inactive` to `nil` (leave as is). This is the reverse of the usual default values. ``` auto-editor example.mp4 --when-active cut --when-inactive nil ```

Exporting to Editors

Create an XML file that can be imported to Adobe Premiere Pro using this command: ``` auto-editor example.mp4 --export premiere ``` Auto-Editor can also export to: - DaVinci Resolve with `--export resolve` - Final Cut Pro with `--export final-cut-pro` - ShotCut with `--export shotcut` - Kdenlive with `--export kdenlive` - Individual media clips with `--export clip-sequence`
