Fractal noise issue
Hello,
I have some layers with fractal noise, and I’ve animated the evolution and the offset turbulence. I’ve done this many times before, but now I have a weird problem: The animated fractals “jump” to the image they should have at the last keyframe… but way too early! In other words, If the length of the comp (and the fractal noise layer) is 5 minutes, and I have my keyframes at the beginning and the end of the comp, then the fractals move and pulsate till lets say 1 minute, and from that point it just shows a non-moving image of what should be only on the last frame! The actual times this happens vary, I’m just using these times as an example. I also tried starting a new project with nothing else in it but the fractal noise layer, but the problem is still there, so it’s not something else in the project that’s screwing things up. Strange stuff.. any ideas what’s going on?
Kind regards,
Eric -

Never seen this but try turning off all of the other layers and see what happens to the Fractal Noise layer.If it seems to work, print it as a stand alone movie and import it to replace the effects layer.

Thanks for your reply,
Yea my first thought was that one ore more other layers were affecting the fractal layer, which is why I tried starting a brand new project with nothing in it but the fractal layer. But it’s happening there as well. Crazy stuff! Could it have anything to do with my graphics card? I just upgraded to a Quadro FX 3700. I don’t know if it matters, but this workstation (HP xw9300, 2 dual Opterons, 4 Gb Ram) is a Matrox Axio.
So: Any other ideas what I might look at? This just doesn’t make any sense. I found a workaround for now: Trimming the fractal layers where the animation freezes, duplicating it and sequencing it with dissolves, but it don’t look great! 🙁
Anyone..?Kind regards,

I don’t see how but I’m a Mac guy. The only way the card could affect Fractal Noise is if the effect is strictly rendered by the card’s hardware; not likely, but you can turn off the card’s OpenGL (or turn it on if it’s off) and see if that makes any difference.
Sorry not to have anything better to offer, I cannot recall anyone ever posting a similar issue with Fractal Noise.

Yes, I tried turning off OpenGL, but it didn’t help. I just discovered that there is a new update to AE, Premiere and other CS4 programs. I’m downloading it right now, and hopefully the update will fix this. But the fact that I haven’t heard of anyone else having this problem makes me doubtful. But we’ll see.. I’ll post back when I have the updates installed.
Kind regards,
Eric
