Planet Timelapse - Simulation error?

So I have been thinking of doing this for a while. I made a small Arduino program that would press F10 every few seconds (five in this case) to produce a timelapse. Ended up with:

So this is 5 seconds per frame and played back at 25FPS

Cool, but I imagine the background stars have much less distance to travel in each frame so they look smoother. Can you play it back faster and is it less noticeable?

The jump was also noticeable while watching the game run (this clip was made with over 3 hours of images). It weird having seen others where the orbit period is very low and in real time you can watch a planet whip past its moon!

Seems to me that the planet being much closer it moves a greater distance between each frames than the background, and this is what makes the difference.

The jump was visible in real time as well. The jump is every 6 frames so the planets position was only updated every 30 seconds approx. Just seems weird.

Even when played back at twice the speed the planet looks choppy.
As if the it is running on a different and lower tick than the planet you are on.
I would forward this to FD, see if they can make any sense of it.

After months that you posted it...
I find myself in a similar situation...
I think it is the extreme vicinity of the planet-moon.
I think it is how the simulation work... bit by bit...

It's to do with the proximity of satellites to their parent body - the simulation engine appears to have issues with close orbiting bodies. The way Stellar Forge deals with it is by going a bit crazy... Every 30 seconds it simply teleports the satellite along its orbital path...
It's not usually visible in supercruise, but once you drop into normal space, the nature of such "mojo moons" becomes apparent.
