How to get a pixelated image? I'm trying to make an animated pixel art sprite. I can render it no problem at its normal size settings, but when I set the image size extremely low, it doesn't come out like it should in avi jpeg form. When I render the sprite at its full resolution, it looks like this: 
I tried to pixelate it by setting the resolution extremely low, and got this: 
That's what I want. I want the image to be pixelated, but when I export the full animation as an avi jpeg video, it completely blurs the image beyond all recognition because it's such a small image. This is what the output looks like: 
How do I render / export / format / scale the image such that I will get a sharp, clean pixel animation, with every frame looking like the second picture?
You can use a Pixelate node in the compositor. Go to the Compositing Screen Layout or open a Node Editor some other way. Make sure the Compositing Nodes button is selected.



Use the following setup. Notice how the left side of the gun is pixelated, but the right side is normal. In the final render, it will all be pixelated. Additionally, see how the both Scale node's X and Y values are equal. Also notice how between them they equal 1 (0.2 x 5 = 1). This means that the overall scale of the gun image doesn't change.



If you so desire, you can copy the node setup straight from the following file (gun not included) (sorry) (it does include an awesome hippie monkey, tho). Lastly, you can read more about the Pixelate node here.
