Flash vector animations are infinitely scalable from a very tiny file size. The vectors in modern codecs are motion vectors. They don't generally have any concept of drawing primitives like splines, polygons, fills, gradients, etc., and they are raster formats so they have a fixed native pixel size. The idea of a vector codec isn't new though, and prior attempts have been made, though I don't remember enough details to find a reference. Just for anyone who might not be familiar, "vector" in this context refers to the graphics you would generate in a tool like Inkscape, where you can define complex geometric shapes with just a few datapoints. "Raster" graphics are what Gimp works with, where each pixel is specified (effectively) individually.
