Mandelbulb 3D. Rotating objects problem.

[DonTen]

I'm trying to render a simple object rotating through 360degrees (attached m3a).

Everything seems fine until I run the finished animation which always seems to skip (or add?) a few frames. I've seen these types of animation working perfectly elsewhere so I'm pretty sure the issue lays with me, not the software.
Could a kind soul point out my error?

(I'm guaranteed to be missing something horribly obvious, but I'm currently stumped.)

You have it set for Quadratic Interpolation.  To hit the keyframes exactly you need Linear Interpolation. 

If you want the best of both worlds, try duplicating the first keyframe, setting the number of frames to the next keyframe at Zero.  Do the same for the final keyframe, setting the number of frames to the next keyframe at Zero for the next to last keyframe.

Hope I phrased that intelligibly...

Thank you for the assistance, got it working perfectly now.

Thank you for the assistance, got it working perfectly now. 

Glad it worked

Especially for a rotating loop animation:
- check the 'Loop animation' checkbox 
- if you use 3 keyframes, let each rotate 120 degrees further and give all the same subframe count, no need to copy a keframe.
