FFmpeg provides simple usage to convert video such as .mkv, .mp3, .mp4, .mov to .gif.

Install Ffmpeg on Mac OS

 brew install ffmpeg

 ffmpeg -i <input.video> out.gif

The file size of out.gif is sometimes a bit too big. In such a case, it's better to use -r option to specify frame rate.

 ffmpeg -i my-sample.mov -r 10 out.gif

Scaling the video to a width of 640. FFmpeg calculates the height for us because we entered -1. It will keep the aspect ratio of the original video.

 ffmpeg -i my-sample.mov -r 10 -vf scale=640:-1 out.gif
