Well - kind of. For short videos the amount of field rotation you get can be handled well by AutoStakkert, but it doesn't automatically perform field derotation per se. There is an option to remove field rotation in AS!3, but it's only enabled for monochrome videos, trying to perform the technique on raw (undebayered) videos destroys the bayer matrix and screws up the colours, and trying it on RGB (debayered) videos will not work at all.

WinJupos can remove both field and disc rotation on longer videos, and since 11.1.6 it also preserves the Bayer matrix (so debayering can be performed in AS!3).
Short answer - if you are imaging just the planetary disc for short times (<3 min for Jupiter, <5 min for Saturn), and are not trying to image the moons of these planets, then field rotation is not an issue. If you try imaging for longer than these times or you want to image the moons, then you need to look into using WinJupos to remove the rotations.
Of course, this is only applicable for planetary work, for DSOs that's a whole other story
