My gif workflow

.zshrc

gifify() {
  if [[ -n "$1" ]]; then
    if [[ $2 == '--good' ]]; then
      ffmpeg -i $1 -r 10 -vcodec png out-static-%05d.png
      time convert -verbose +dither -layers Optimize -resize 600x600\> out-static*.png  GIF:- | gifsicle --colors 128 --delay=5 --loop --optimize=3 --multifile - > $1.gif
      rm out-static*.png
    else
      ffmpeg -i $1 -s 600x400 -pix_fmt rgb24 -r 10 -f gif - | gifsicle --optimize=3 --delay=3 > $1.gif
    fi
  else
    echo "proper usage: gifify <input_movie.mov>. You DO need to include extension."
  fi
}

Install.sh

brew install ffmpeg
brew tap phinze/homebrew-cask
brew install brew-cask
brew cask install x-quartz
open /usr/local/Cellar/x-quartz/2.7.4/XQuartz.pkg
# click through the stuff
brew install gifsicle
brew install imagemagick

# I had a weird problem with Convert/imagemagick where I had to do:
ln -s /usr/local/Cellar/libtool/2.4.2/lib/libltdl.7.dylib libltdl.7.dylib
# But hopefully you don't have to

usage.sh

# Take screencast using Quicktime. Export as high quality as possible.

gifify screencap.mov
gifify screencap.mov --good

Not sure if anyone cares about the output, but I like to make my bash functions quiet and less verbose... Here is my stab at it. The output of the command is much prettier. I also added the ability to scale it to a max width (via an argument to the gifify command)...

function gifify {
  if [ -z "$1" ]; then
    echo "$(tput setaf 1)No input file given. Example: gifify example.mov [max width (pixels)]$(tput sgr 0)"
    return 1
  fi

  output_file="${1%.*}.gif"

  echo "$(tput setaf 2)Creating $output_file...$(tput sgr 0)"

  if [ ! -z "$2" ]; then
    maxsize="-vf scale=$2:-1"
  else
    maxsize=""
  fi

  ffmpeg -loglevel panic -i $1 $maxsize -r 10 -vcodec png gifify-tmp-%05d.png
  convert +dither -layers Optimize gifify-tmp-*.png GIF:- | gifsicle --no-warnings --colors 256 --delay=10 --loop --optimize=3 --multifile - > $output_file
  rm gifify-tmp-*.png

  echo "$(tput setaf 2)Done.$(tput sgr 0)"
}

Hmm....I'm getting the following:

convert: unable to load module `/usr/local/Cellar/imagemagick/6.8.9-1/lib/ImageMagick//modules-Q16/coders/png.la': file not found @ error/module.c/OpenModule/1282.
convert: no decode delegate for this image format `PNG' @ error/constitute.c/ReadImage/501.
convert: no images defined `GIF:-' @ error/convert.c/ConvertImageCommand/3187.

I checked and that file exists. I've reinstalled imagemagick and libpng umpteen times now. Not sure what else to try

Few issues getting stuff installed, Xquartz seems to have changed names and versions, but now getting an error gifify:7: command not found: ffmpeg any thoughts? :(

@thatryan It sounds like ffmpeg didn't install right.

• Try running the command ffmpeg, if that seems to fail, try installing again brew install ffmpeg.
• If brew seems to be unhappy about that, try brew doctor

afaik the install.sh can now just be

brew install ffmpeg gifsicle imagemagick

i don't believe xquartz is at all neccessary. (not sure why it was.)

Worked pretty good for me.

brew install ffmpeg gifsicle imagemagick

Thanks @paulirish & @SlexAxton

Wow, I like @tonycoco's solution. Well done!

I've added the gifify function to my bash-it fork: nwinkler/bash-it@e4bdad6

There's now an installable binary for that, lots of options, optimized! https://github.com/vvo/gifify

I get error on that command: brew install brew-cask

Error: Failed to download resource "brew-cask"
Failure while executing: git clone --depth 1 --branch v0.53.3 https://github.com/caskroom/homebrew-cask.git /Library/Caches/Homebrew/brew-cask--git

Anyone come across this error?

Incompatible pixel format 'rgb24' for codec 'gif', auto-selecting format 'rgb8'

If this helps anyone, my XQuartz location ended up being:
open /opt/homebrew-cask/Caskroom/xquartz/2.7.7/XQuartz.pkg
I assume that's due to the update to 2.7.7?

thatryan: Yes, I have that error (Yosemite). No idea what to do about it.

For those looking to install @vvo's gifify with prerequisites:

# install pornel/giflossy (fork of gifsicle)
wget https://github.com/pornel/giflossy/releases/download/lossy%2F1.82.1/gifsicle-1.82.1-lossy.zip
unzip gifsicle-1.82.1-lossy.zip -d gifsicle-1.82.1-lossy
cp gifsicle-1.82.1-lossy/mac/gifsicle /usr/local/bin/
# install ffmpeg
brew install ffmpeg --with-fontconfig --with-libass
# install imagemagick
brew install imagemagick --with-fontconfig
# install gifify
npm install -g gifify

Thanks @vvo, @pornel, @paulirish, @SlexAxton, and internets.

Please forgive my ignorance on the matter. I really want to use this as it seems the only method for high quality gifs.
I understand this is for MAC users only? I do have a mac pro. How can I use this script?
Thanks so much again!

@nexdrew could you please add this to the gifify repo as a PR? very valuable

@vvo and @nexdrew, here's a PR that does it in a curl one-liner: vvo/gifify#46. Feedback?

For anyone else interested, installing gifify locally works pretty well too.

$ npm install --save-dev gifify

… in your package.json:

"scripts": {
  "gifify": "gifify"
}

And can be run from command line like so:

$ npm run gifify -- -o test.gif test.mp4

… or js script within package.
