How do you make gifs?
I've got a really silly question.
I saw many gifs in here but I can't understand what do you guys use to create them. I tried Gyazo but look at the result:

Everything is too dark and the file weights too much.
After that I found someone made a gif from the same game:

Colors are much brighter and the weight isn't so big. I do understand that I can ask this question in Google, but I think developers could help me more!

Thank to all who will try to help!
