Great info.

I think I get it now.  "Estimated viewpoint distance to the surface" is good for zoom animation and "Distance form last keyframe" is good for flight animations.

What do you recommend as a good average number for "Distance form last keyframe" for fluid flight?

It depends how close to the fractal surface you want to fly. Total size of Mandelbox is about 10. So if you go with step about 1.0, you will go through whole Mandelbox in about 10 keyframes. But if you want to fly between of some detailed structures very close to the fractal, step value 0.000001 should be to high (or to low). You have to feel it. There is no recipe for this. Flying speed can varying along the animation. If you the camera is far outside the fractal, you can move the camera by long distance. But during closing up the fractal surface you can decrease speed. Try to imagine you want fly from the Earth to some of the Jupiter's moon. First you have to start with small speed to go through the atmosphere. Next you have to accelerate dramatically to decrease travelling time. When you are need Asteroid belt you have to slow down to avoid collision with some body. Next you have to accelerate again, because you have very long way to travel. When you are close to the Jupiter you have to adapt the speed to the new reference point and find the target moon. The flight can be fluid if you change the speed smoothly. You have to continuously adapt the flight speed to actual situation. It will be senseless if you travel (move the camera) always with the same speed.

Okay, getting a lot of crashes here with version 0.991 when trying to animate. There is no specific moment when Mandelbulber crashes: it can be with movement, with selecting path to store images, when altering a value, and so on. Don't know if the error Windows is giving is of any use if I copy and paste it here?

Windows 7 Professional 64bits
Mandelbulber 0.991

Menno

Edit: okay, don't know if it is use-full, but this is the kind of error I get (it's in Dutch since my Windows 7 is in Dutch. If needed I can translate):

I tried to find some bug in program which could cause crashes. I used powerful tool valgrind which trace program for some uninitialised variables, missed memory allocations or delete[]. I found some minor problems but I don't think so they could cause crashes.
I have made also several tests on Linux (64-bit) and Windows Vista (also 64bit) to try crash the program, but without result. Program worked every time very stable.
Maybe this is some problem with compatibility of GTK+2.0 library (responsible for GUI) and Windows 7.

Did you tried to run Mandelbulber in Windows XP emulation mode?

If you want to create smooth flight you should try to keep for each keyframe similar values for  "Distance form last keyframe" - you will get almost constant flight speed.
.
.
Step for camera moving multiplied by DE: from 0.5 to 3.0
Absolute distance mode: checked for flight animation, unchecked for closing up
Absolute movement distance: depends on required flight speed and how close to fractal surface the camera is


It depends how close to the fractal surface you want to fly.... But during closing up the fractal surface you can decrease speed.

In a flight animation.  You stated to keep "Distance form last keyframe" similar for constant speed but also said it depends how close you get to the fractal.
So one would have to go by eye when changing from a parallel course to going close?
Could one change from "Absolute distance mode" to "...multiplied by DE" for flight animations when going close to a fractal so you don't have to manually change movement distance?
