You did something with quality normaly a gif is something very quick and with low quality.
I have also ffmpeg but I never use it in details, in fact I downloaded it only, because I needed to open a certain file, but it was interresting so I keep it since now and now that you give me some commands I will check it in details.
I am curious an I took a view of yours explanations, I dont understand,but with a little practice this will be better, my next learn program will be probably how work a script, I discover that the modern games working a lot with scripts, so is my next step, only to be more awake about new generation of games, I guess Python is a good base for this ...
Thank you @IanL for your time to explain how work the program !
