Variants in the Brainstorm window
on Mar 24, 2013 at 1:21:29 pm

As far as i know, 9 different variants (example images) should be displayed in the Brainstorm window. But sometimes -especially when i pick multiple effects on one or more layers- i get less than 9 variants in the Brainstorm window. Each time i click the Brainstorm button the number of variants changes but somehow it doesn't show all 9. Is this a problem, or i should consider this as normal?

Here are some screenshots of the issue:

After Effects tries to show 9, but if you are asking it to do a lot of rendering on an underpowered system, it will fall back to showing as many as it can. The more complex the composition that you are working with, the fewer tiles can be rendered.

Consider that this feature is asking After Effects to render 9 compositions in real time, so it's not surprising that sometimes it struggles.

Fractal Noise is an especially taxing effect, and Glow is rather render-intensive, too.

BTW, why aren't you using the Turbulent Noise effect? It was created to replace Fractal Noise; it's nearly identical and much faster.

@Todd

My system has 32 gb ram, gtx 670, i7 3770K, ssd+hdd. Do you think this is underpowered for this kind of task?

I selected the effects randomly just to learn how Brainstorm works. But it is good to know Turbulent Noise is better. Thanks.

Regardless of the subject, do you have any AE full-course other than the ones with Angie? I find your lessons quite informative and easy to understand but they are rare. I hope you make more courses and make them alone. :}

The effects that you applied are very computationally expensive, so even a good CPU is going to struggle to render 9 instances of them in real time. The RAM, GPU, and disk drive don't matter for these effects.

I'm glad that you like them.

Here are the 10 courses that I did with video2brain:

8 of them are just me. 2 of them (the Learn By Video series) are half me and half Angie.

If you're not just looking for videos, but also like to read, you can find more stuff by me here:

That's the category of the After Effects team blog that I write in; the other categories are by our marketing folks and product manager.
