Multigifatron - make gifs from single files and videos from those gifs
* if using windows and git bash you will need to add magick to begining of imagemagick commands like convert or mogrify you will need to install imagemagick and ffmpeg to use webscraping via lynx you will have to install lynx on linux on windows you will have to download lynx and place it into the git bash /usr/bin folder
