I wasn't expecting the really small baffles inside the SpaceX tank as compared to the huge baffles that I had seen in that film from the Saturn. They must've decided that a little baffling went a long way.
Here's one of the interior of an S-IVB stage as it flies to orbit and then shuts down... while the engine is burning, the liquid hydrogen is kept firmly seated on the aft dome of the tank, but when the engine shuts down, it floats off across the tank in great splattering globules that spread themselves over the quartz window the camera was looking through, which explains the distortion. Once it settles down, though, you can see great blobs of liquid hydrogen floating around inside the tank...
On "The Mighty Saturns" video from Spacecraft Films, the entirety of the Saturn I interior tank view is shown... near the end of the video, when the engines shut down and the retros fired to separate the stages, the propellant comes RUSHING back up the baffles and core toward the camera due to the negative acceleration imparted to the coasting stage, spraying the camera window with propellant.
Watched the lauch live.... didn't know what I was looking at for a while, thought... "fuel tank? I'd be pretty wary of putting a camera in there." It looked more and more like a pool of liquid as the flight progressed (and the level drained down), then... massive "wow, that's ridiculously cool" as the second stage hit MECO and the propellant globule'd up in the center.
