Of course, synchronizing the music would give much better results.
But it would also require significant work (from my point of view) :
probably to learn new software, measuring and identifying the "beat"
(not necessarily regular in classical music), calculating the number of
frames between each keyframe, testing, testing...
Ohhh... I definitely understand how much extra work would be involved!!! But as long as the video did not pulse, jerk or dance around, then the actual "beat" would not really be that critical. It then comes down to volume and tempo matching the action:
• If there is a crescendo, then one would expect the animation to grow with the music. (Or the opposite for diminuendo.)
• If the music is allegro, then the action should be cheerful or brisk, as in lively.
• If it is adagio, then the movements of the animation would be at ease; performed more slowly.
• If the music is forte, then the animation might be more dynamic (as in color, size, and/or action).
The overall speed of a piece of music (tempo), along with the volume at which it is played at, have always been some of the crucial elements when movies are produced. And when they do not match, then it becomes distracting to the viewer.
Also in this particular case, as it was my first video using Jesse's program,
it was a kind of test and I did not intend to produce a very polished piece
of work (in fact I never do!)
I can understand this as well, since my first attempt with Jesse's software back in March was definitely not a "polished piece", nor was it meant to be:
http://www.fractalforums.com/index.php?topic=3056.0 But while testing that particular version of
Mandelbulb3D, without using any keyframes at all, I started thinking about how I wanted the basic video to be made to match the music. (It was strictly a test run; still working on the full-length HD version in my spare time.)
Just a quick note on the shapes : in the beginning, almost all the rotation
parameter values in keyframes are 0,45, 90, 180. That creates a sort of
symmetry in the chaos, even if you understand that varying 1 parameter
from 0 to 45 and another one from 0 to 90 does of course create dissymetry,
there are always simple ratios between the components of the rotation.
Appreciate the notes on how you went about transforming the various shapes. Always nice to have a detailed account of the work involved.
