NOTE FROM AUTHOR
I am no more using this project or providing any support to it, if you want to maintain it, ping me here:vincent.voyer@gmail.com.
This project was created 4 years ago, there might be better ways to turn a video into a GIF now, use google!
/NOTE FROM AUTHOR
Convert any video file to an optimized animated GIF. Either in its full length or only a part of it.
This screencast was recorded withlolilolicon/FFcast then converted to a GIF with:
gifify screencast.mkv -o screencast.gif --resize 800:-1
- command line interface
- programmatic JavaScript (Node.JS)stream interface
- unix friendly, supports
stdin&stdout - optimized! usespornel/giflossy to generate light GIFS
- lots of options: movie speed, fps, colors, compression, resize, reverse, from & to, subtitles
- no temp files used, everything happens in memory
- fast! Extracting a 5-second GIF from the middle of a 2-hour movie takes less than 20 seconds
Before using gifify, please install:
- Node.js (
$ brew install node) - FFmpeg🐓🐓🐓🐓 (
$ brew install ffmpeg) - convert, the famousImageMagick (
$ brew install imagemagick) - pornel/giflossy, it's agifsicle fork (waiting forgifsicle#16 to be merged) (
$ brew install giflossy)
You can also use thegifify Docker image which comes with everything installed.
npm install -g gifify

See theexample.
varfs=require('fs');vargifify=require('gifify');varpath=require('path');varinput=path.join(__dirname,'movie.mp4');varoutput=path.join(__dirname,'movie.gif');vargif=fs.createWriteStream(output);varoptions={resize:'200:-1',from:30,to:35};gifify(input,options).pipe(gif);
You can also pass areadable stream togifify(stream, opts).
Gifify supports streams both on command line (cat movie.mp4 | gifify -o out.gif) and in the programmatic API (gifify(readableStream, opts).pipe(writableStream)).
While it's super useful in some cases, if you have the file on disk already, you better dogifify movie.mp4 -o out.gif orgifify(filePath, opts).pipe(writableStream).
Why? Because piping 3.4GB when you want to cut from 40:20 to 40:22 still takes a loooooot of time and does not give you any performance benefit.
FFmpeg has to read from 0GB -> $START_BYTE_40:20 and discards it. But everything flows in your memory.
When using direct file input from command line, we pass the-i filename option to FFmpeg and then it's super fast!
Be careful when|piping.
You can burn some simple text into your GIF:
gifify back.mp4 -o back.gif --from 01:48:23.200 --to 01:48:25.300 --text"What?..What?What?"Result:
You can burn subtitles into your GIF, it's that easy:
gifify 22.mkv -o movie.gif --subtitles 22.ass --from 1995 --to 2002 --resize 600:-1
You must create new subtitles files, the timecodes for the complete film will not work for a five seconds GIF.
Create subtitles usingaegisub and augment the font size for a great effect!
Here's the22.ass from the previous command, created with aegisub:

On modern hardware GIF is the slowest and most expensive video codec. Can we please allow it to be obsoleted?https://pornel.net/efficient-gifs#sec44
YOLO!
Giflossy is a fork ofgifsicle, gifsicle author is currentlyworking on integrating the lossy part in gifsicle.
So in little time we will be able to directly use gifsicle and gifiscle packages.
jclem/gifify was a great source of inspiration.
