Finished up a set of preview images for this encounter:
https://pirlwww.lpl.arizona.edu/~perry/Juno/pj55.htm This uses the PJ53 images as a template for image timing, so images every 3 minutes ±10 minutes of C/A then wider spacing outside of that. Juno is oriented so that is off nadir so it does a better job of keeping Io in the middle of the JunoCam FOV (and JIRAM centered on Io as well, which is great as the drift near C/A can lead to only a few images being taken making summed images have poorer quality). -------------------- &@^^!% Jim!

This will be the first of 4 flybys that will definitely improve mapping of Io.

Pj53 already helped north of ~65N, particularly with mapping where mountains are.

I didn't know about Juno's orbit possibly being changed. That is fascinating.

Scott Bolton mentioned it at OPAG back in May and the dates and distances come from that presentation. That change hasn't shown up in the form of a new reference trajectory, so I don't know what the status of that orbit change.

I use Cosmographia from NAIF: https://naif.jpl.nasa.gov/naif/cosmographia.html . I have a custom add-on for Juno that uses all the latest kernels and has footprints for JIRAM, JunoCam, and the SRU. I've attached a zip file of it here, but note that you still need to gather up all the necessary kernels. I've also attached a txt file copy of my meta kernel so you can see what ones you need to download.
For actually creating the video, I used Final Cut Pro, but I suspect you were asking more about the visualization tool.
Attached File(s)

I use Cosmographia from NAIF: i do the same but use celestia with a ton of kernels . My ssc file for the spacecraft is getting a bit long and the folder is 4.9 Gig in size |

So far so good. reconstructed c-kernel dropped about 30 minutes ago.

We've got some plumage, and Jupiter-shine illumination.
