I follow a lot of tumblr blogs of ppl that work with processing.. Their gifs look amazing... Whenever I try to save my work in gif with the gifMaker lib or making a video with core lib and using some other program to transform it into a gif file, the result is horrible, glitchy and results in a huge file.

Any suggestions on how to do it right? Maybe something to do with image quality, size, some configuration, the right programs to use??
