Where does the air go when pressure casting?

One of the YouTuber's I'm subscribed to runs what he called a "pot cam," whereby he puts a camera and a flashlight inside his pressure pot and runs the footage at a time-lapse. One thing it makes clear is that hardening resin inside a pressure pot is not static: it moves and swirls around, with convection currents stirring the resin. As best I can tell from his footage, the bubbles are carried by the moving resin and move towards the surface. They probably dissolve off.
