Alejandro, avconv made video with default settings. If you know which settings i must to change to improve quality, welcome.
Also, you can run avconv manually via terminal command like that avconv -r 5 -i /home/alejandro/Blink%05d.jpg /home/alejandro/Blink.avi
Yes, i have many ideas! I want add command line into Blink interface, and user will able to change any settings of avconv.
But, before, i must redirect avconv output to PI Console.
