Create gifs from still photos using ImageMagick

If you want to create gifs from sequence of photos just like how modern photo-booth does, here is a quick command line tool that gets the job done.

Setup

1. Install homebrew – https://brew.sh/

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Once installation completes, read the closing notes. It might ask you run few commands like this.
    echo '# Set PATH, MANPATH, etc., for Homebrew.' >> /Users/pkasi/.zprofile
    echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/pkasi/.zprofile
    eval "$(/opt/homebrew/bin/brew shellenv)"

2. Install ImageMagick – https://imagemagick.org/script/download.php

brew install ImageMagick
brew install ghostscript

4. Run the tool to create gifs from photos

Earlier the command was convert now both convert and magick works

# Switch to the directory that has multiple jpg or png
convert *.png selfie-nov-2022.gif
  (OR)
magick *.png selfie-nov-2022.gif

You can using -delay options to control the speed of image switching and -quiet to suppress all warning that gets logged in the terminal. Read more about different options here

magick -delay 50 *.png selfie-nov-2022.gif
magick -quiet -delay 100 selfie-dec-2022.gif
