I want to have some nice smooth circles on my image, but as you can see it’s a bit pixelated. Any ideas?

The simplest way to draw a circle in opengl is with jit.gl.gridshape @shape circle. You can capture this to a texture to mix with video. In your case, you’d probably want to use a jit.gl.slab with the co.lumakey.jxs shader.

also, it looks like you’re drawing multiple circles. You can do this by using jit.gl.multiple can keeping all of the position/size info in a matrix.

you will get a huge speed bump by using OpenGL to boot.
