I remember (in the foggy recesses of my mind) that I had a similar problem when raytracing frames for output as animation via Scala MM400.
I got around the problem of the changing pallet by selecting 6 of the most varied frames in the sequence (by varied, I mean in colour) and scaling them down to one sixth their size, then saving them on disk. Then I loaded up DPaint (IIRC), set the screen resolution and mode to the same as the final output of the animation, then loaded all six images as brushes and pasted them onto the screen. I had a first frame with all the colours I was likely to use. I then imported the rest of the frames and deleted the first composite frame before saving the animation.
I'll have to look at it again to nail down the details. I used sooooooo many programs, and many processing sequences. Sadly I haven't done animations for a long time, so I have forgotten many of the little tricks I used to use.
