Video 2 Gif is a python tool created by Lorenzo from atareao.es which uses Mplayer to convert the video to GIF and lets you configure the start and end frame, video size and the frame rate.
Before downloading and using Video 2 Gif, make sure you have mplayer installed:
sudo apt-get install mplayer
Then, download Video2Gif from here:

To run Video 2 Gif in terminal
video2gif
小弟試過，轉成GIF的畫質如果是卡通還OK，如果是真人的影片比ffmpeg差，也不如網站好。
玩玩看囉！enjoy!
