Video-GIF Converter

Video to GIF and viceversa converter

It uses ffmpeg and gifski under the hood. They are both installed automatically as dependencies by this package.

Getting started

To get started with this library, you need to install it and add it to your project.

Installation

# npm
npm install video-gif-converter --save

# yarn
yarn add video-gif-converter

Library Usage

API Reference available at https://pichillilorenzo.github.io/video-gif-converter/.

import * as path from 'path';
import {VideoGifConverter} from 'video-gif-converter';
// or
const path = require('path');
const {VideoGifConverter} = require('video-gif-converter');

const command = new VideoGifConverter({
  convertTo: VideoGifConverterConvertType.gif,
  output: path.join(__dirname, 'test', 'output'),
  gifski: true,
  quality: 100,
  startTime: 3,
  fps: 15,
  size: '640x?'
});
command.on('progress', progress => {
  console.log(progress);
});
// glob pattern
const files = path.join(__dirname, 'test', '**', '*.mp4');
const result = await command.run(files);

CLI Usage

<pattern> represents a glob pattern used to specify input files to convert. Surround the glob pattern with quotes (example './test/**/*.mp4').

Usage: video-gif-converter [options] <pattern>

Examples: 
  video-gif-converter --gifski -q 100 -o './test/output' './test/video.mp4'
  video-gif-converter --use-palette -o './test/output' './test/video.mp4'
  video-gif-converter --fps 10 './test/**/*.mp4'
  video-gif-converter --convert-to video --format mp4 'test/**/*.gif'

Arguments:
  pattern                         Glob pattern of input files. Surround the glob pattern with quotes (example './test/**/*.mp4').

Options:
  -ct, --convert-to <type>        Convert to gif or video. (choices: "gif", "video", default: "gif")
  -o, --output <path>             Output folder path.
  -f, --format <format>           Output video format. Used and required only if --convert-to is video.
  -r, --fps <fps>                 Output framerate.
  -s, --size <size>               Output frame size (examples: 640x480, 640x?, 50%).
  -a, --aspect <aspect>           Output frame aspect ratio (examples: 4:3, 16:9).
  -g, --gifski                    Use gifski to generate GIF
  -q, --quality <1-100>           GIF output quality used by gifski
  -df, --delete-frames            Delete generated frames used by gifski (default: true)
  -vc, --video-codec <codec>      Video codec (examples: mpeg4, libx264).
  -vb, --video-bitrate <bitrate>  Sets the target video bitrate in kbps. The bitrate argument may be a number or a string with an optional k suffix.
  -vbk, --video-bitrate-constant  The constant argument specifies whether a constant bitrate should be enforced. (default: false)
  -d, --duration <seconds>        Forces ffmpeg to stop transcoding after a specific output duration. The time parameter may be a number (in seconds) or a timestamp string (with format [[hh:]mm:]ss[.xxx]).
  -st, --start-time <seconds>     Seeks an input and only start decoding at given time offset. The time argument may be a number (in seconds) or a timestamp string (with format [[hh:]mm:]ss[.xxx]).
  -l, --loop <times>              Set the number of times to loop the output. Use -1 for no loop, 0 for looping indefinitely (default).
  -up, --use-palette              Use ffmpeg palettegen and paletteuse filters to generate high quality GIF without gifski.
  -h, --help                      display help for command

CLI Usage Example

video-gif-converter --gifski -q 100 -o './test/output' './test/**/*.mp4'

This code snippet shows how to put into action video-gif-converter to convert all .mp4 video files into high quality GIFs using the gifski encoder.
