Here is what I have done, and I will share it for all other dorks, to make life easier, or possibly more complicated, depending on your outlook. Enter admin password as needed, this is all safe stuff.
-Install Homebrew. http://brew.sh …all you have to do is paste the command found on their homepage into Terminal.app. Or just get it here:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
-Install some GIF making utilities. BUT, if your computer is like mine, you will get a permissions error…I had to do:
sudo chown -R $USER /usr/local
…to get utilities to install correctly.
After that, you want to:
brew install ImageMagick mplayer gifsicle
Then, go here: https://github.com/minimaxir/video-to-gif-osx
This guy has made some "apps" that piggy back on this stuff, so that you don't have to convert via Terminal. I had luck with the already compiled "Convert Video to Gif App Custom.app". The utility that works directly in Finder looks pretty cool, but I haven't tried that yet.
If you get errors, I would advise to check that your filename doesn't have a space. I haven't used this much yet… I did get an empty GIF as a result one time, and the ReadMe file suggested that spaces in filenames can be a problem, so head's up on that one.
