There are several things to notice in this video. You can see Io, Europa, and Ganymede turning off and back on again as they pass into Jupiter's shadow. You can see belts and zones begin to come into focus as Juno approaches. Sometimes, if you squint, you can spot the red spot. You can see Jupiter's belts fall to a steeper angle as Juno begins to rise in latitude. Some of the moons, especially Callisto, look kind of blinky -- this has to do with the way that the JunoCam instrument works. It's designed for extended targets (things that fill many pixels), not point targets. Scott Bolton said on the press panel this evening that at this phase angle, Callisto was dimmer than predicted. Its dim light, combined with the sharpness of the JunoCam optics, meant that its light was focused into a very small area on the detector. On the JunoCam detector, not all of the area is active, meaning that photons can fall in between pixels, or at least in between areas where they would be detected. When Callisto's light fell into those areas, it seemed to dim in the movie.

Juno principal investigator Scott Bolton was repeatedly asked about plans to release the raw images. During the morning press briefing he said that their release "depends on what we see [in them] and how interesting it is," but by the evening he was saying that the mission intends to release them within a few weeks, though he wasn't specific as to the timeline, citing "technical issues." You can bet I'll keep asking!
