## README

# editly 🏄‍♀️

[![demo](https://github.com/mifi/gifs/raw/master/commonFeatures.gif)](https://youtu.be/LNeclLkxUEY)

This GIF / YouTube was created with this command: "editly [commonFeatures.json5](https://github.com/mifi/editly/blob/master/examples/commonFeatures.json5)". See [more examples here](https://github.com/mifi/editly/tree/master/examples#examples).

**Editly** is a tool and framework for declarative NLE (**non-linear video editing**) using Node.js and ffmpeg. Editly allows you to easily and **programmatically create a video** from a **set of clips, images, audio and titles**, with smooth transitions and music overlaid.

Editly has a simple CLI for quickly assembling a video from a set of clips or images, or you can use its more flexible JavaScript API.

Inspired by [ffmpeg-concat](https://github.com/transitive-bullshit/ffmpeg-concat), editly is much faster and doesn't require much storage because it uses **streaming** editing. Editly aims to be very extensible and feature rich with a pluggable interface for adding new **dynamic content**.

## Features

- Edit videos with code! Declarative API with fun defaults
- Create colorful videos with random colors generated from aesthetically pleasing palettes and random effects
- Supports any input size, e.g. 4K video and DSLR photos
- Can output to any dimensions and aspect ratio, e.g. *Instagram post* (1:1), *Instagram story* (9:16), *YouTube* (16:9), or any other dimensions you like.
- Content is scaled and letterboxed automatically, even if the input aspect ratio is not the same and the framerate will be converted.
- Speed up / slow down videos automatically to match the `cutFrom`/`cutTo` segment length with each clip's `duration`
- Overlay text and subtitles on videos, images or backgrounds
- Accepts custom HTML5 Canvas / Fabric.js JavaScript code for custom screens or dynamic overlays
- Render custom GL shaders (for example from [shadertoy](https://www.shadertoy.com/))
- Can output GIF
- Preserve audio sources or mix multiple
- Overlay transparent images or videos
- Show different sub-clips for parts of a clips duration (B-roll)

## Use cases

- Create a slideshow from a set of pictures with text overlay
- Create a fast-paced trailer or promo video
- Create a tutorial video with help text
- Create news stories
- Simply convert a video to a GIF
- Resize video to any size or framerate and with automatic letterboxing/cropping (e.g. if you need to upload a video somewhere but the site complains `Video must be 1337x1000 30fps`)

See [examples](https://github.com/mifi/editly/tree/master/examples)

## Requirements

- [Node.js installed](https://nodejs.org/en/) (Use of the latest stable version is recommended)
- Should work on Windows, MacOS and Linux. Needs at least Node.js v12.16.2 on MacOS ([see issue](https://github.com/sindresorhus/meow/issues/144)).
  See also: https://github.com/stackgl/headless-gl#system-dependencies
- (Linux) may require some extra steps. See [headless-gl](https://github.com/stackgl/headless-gl#system-dependencies).

Make sure you have `ffmpeg` and `ffprobe` installed and available in `PATH`

## Installing

`npm i -g editly`

## Usage: Command line video editor

Run `editly --help` for usage

Create a simple randomized video edit from videos, images and text with an audio track:

```sh
editly \
  title:'My video' \
  clip1.mov \
  clip2.mov \
  title:'My slideshow' \
  img1.jpg \
  img2.jpg \
  title:'THE END' \
  --fast \
  --audio-file-path /path/to/music.mp3
```

Or create an MP4 (or GIF) from a JSON or JSON5 edit spec *(JSON5 is just a more friendly JSON format)*:

```sh
editly my-editly.json5 --fast --out output.gif
```

For examples of how to make a JSON edit spec, see below or https://github.com/mifi/editly/tree/master/examples

When you run with `--fast` or `fast: true`, it will render a much quicker low-resolution preview ⏩

Without `--fast` it will default to using the **width**, **height** and **frame rate** from the **first** input video. **All other clips will be converted to these dimensions.** You can of course override any or all of these parameters.

**TIP:** Use this tool in conjunction with [LosslessCut](https://github.com/mifi/lossless-cut)

**TIP:** If you need catchy music for your video, have a look at [this YouTube](https://www.youtube.com/channel/UCht8qITGkBvXKsR1Byln-wA) or the [YouTube audio library](https://www.youtube.com/audiolibrary/music?nv=1). Then use [youtube-dl](https://github.com/ytdl-org/youtube-dl) to download the video, and then point `--audio-file-path` at the video file. *Be sure to respect their license!*

## JavaScript library

```js
const editly = require('editly');

// See editSpec documentation
await editly(editSpec)
  .catch(console.error);
```

## Edit spec

Edit specs are JavaScript / JSON objects describing the whole edit operation with the following structure:

```js
{
  outPath,
  width,
  height,
  fps,
  defaults: {
    duration: 4,
    transition: {
      duration: 0.5,
      name: 'random',
    },
    layer: {
      fontPath,
      // ...more layer defaults
    },
    layerType: {
      'fill-color': {
        color: '#ff6666',
      }
      // ...more per-layer-type defaults
    },
  },
  audioFilePath,
  loopAudio: false,
  keepSourceAudio: false,
  allowRemoteRequests: false,
  clips: [
    {
      transition,
      duration,
      layers: [
        {
          type,
          // ...more layer-specific options
        }
        // ...more layers
      ],
    }
    // ...more clips
  ],

  // Testing options:
  enableFfmpegLog: false,
  verbose: false,
  fast: false,
}
```

### Layer types

See [examples](https://github.com/mifi/editly/tree/master/examples) and [commonFeatures.json5](https://github.com/mifi/editly/blob/master/examples/commonFeatures.json5)

#### Layer type 'video'

For video layers, if parent `clip.duration` is specified, the video will be slowed/sped-up to match `clip.duration`. If `cutFrom`/`cutTo` is set, the resulting segment (`cutTo`-`cutFrom`) will be slowed/sped-up to fit `clip.duration`. If the layer has audio, it will be kept (and mixed with other audio layers if present.)

| Parameter  | Description | Default | |
|-|-|-|-|
| `path` | Path to video file | | |
| `resizeMode` | See [Resize modes](#resize-modes) | | |
| `cutFrom` | Time value to cut from | `0` | sec |
| `cutTo` | Time value to cut to | *end of video* | sec |
| `backgroundColor` | Background of letterboxing | `#000000` | |
| `mixVolume` | Relative volume when mixing this video's audio track with others | `1` | |

#### Layer type 'audio'

Audio layers will be mixed together. If `cutFrom`/`cutTo` is set, the resulting segment (`cutTo`-`cutFrom`) will be slowed/sped-up to fit `clip.duration`. The slow down/speed-up operation is limited to values between `0.5x` and `100x`.

| Parameter  | Description | Default | |
|-|-|-|-|
| `path` | Path to audio file | | |
| `cutFrom` | Time value to cut from | `0` | sec |

Certain layers support the position parameter

`position` can be one of either:
  - `top`, `bottom` `center`, `top-left`, `top-right`, `center-left`, `center-right`, `bottom-left`, `bottom-right`
  - An object `{ x, y, originX = 'left', originY = 'top' }`, where `{ x: 0, y: 0 }` is the upper left corner of the screen, and `{ x: 1, y: 1 }` is the lower right corner, `x` is relative to video width, `y` to video height. `originX` and `originY` are optional, and specify the position's origin (anchor position) of the object.

See [position.json5](https://github.com/mifi/editly/blob/master/examples/position.json5)

| `zoomAmount` | Zoom amount for Ken Burns effect | `0.1` | |

## Troubleshooting

- If you get `Error: The specified module could not be found.`, try: `npm un -g editly && npm i -g --build-from-source editly` (see [#15](https://github.com/mifi/editly/issues/15))
- If you get an error about gl returning null, see Requirements.
- If you get an error `/bin/sh: pkg-config: command not found`, try to use newest Node.js LTS version
