This satellite orbits the Earth on the order of ~16 times per day which would not be enough granularity for the smoothness of this video, so I assume it's been combined with other weather data and advanced modelling to provide the smooth interpolation.

But in summary, I don't think the video was heavily constrained by actual CO2 observations, which are done only at a small number of sites on the ground (TCCON or FTIR). The video was probably constructed based on models of plant respiration (which is observed, indirectly, by remote sensing), winds (ditto, of course), and ground emitters.
OCO-2 has offered more significant constraints on global CO2, with a roughly 2km x 2km footprint (per pixel), 1ppm accuracy (in a ~400 ppm quantity), and global coverage every 16 days. There are some videos of observations (not models) at:
Doesn't really impact what you're saying (nor does it alleviate the massive embarrassment of Orbital Sciences).
