Hi there!

I made a short video, just to train a bit my abilities with VisionLab.

I made a Comet coming down, with an great Explosion; I don’t know the exactly name of the explosion, it was the one with the earth on the picture.
I searched all Explosion-presets in VisionLab, but they all have a great problem:
They are quite to fast!

I want a great, “slow”, massive Explosion! =)

In case I just can not make any good preset myself, I thought maybe theres a function to get the explosion into slowmotion? When there’s anyway, I want to know it – on this way the effect would look quite better! (I think on an explosion like the comet in the “look what you can do with VisonLab”-Video on the “discover” page)

Any help? Thanks!

Can't you just change the duration of the effect?

Worst case scenario, you could export just the effect and open it and slow it down in your NLE.

Maybe I can change the duration, but how? That's the question ^^

What's the meaning of NLE?

Or is it possible (and a good looking result) if I render only the explosion, make it slower with Twixtor in Premiere, and than use the compositing aspects of VisionLab?

But how can I make such a explosion like in the video on the webpage (sorry, I don't know the word for this... in german you would say "Anschauungsvideo" or "Demonstrationsvideo")?

That's what I was saying. An NLE is a "non-linear editor". Basically any editing program. You could do that, but I think you can change the duration in the program itself by looking under the effect options in the timeline and there should be an option labeled "Duration"

Hope this helps,

The explosion that you are referring to is a stock explosion, not a particle effect. You can download that footage, and some other explosions, from the AlamDV plug-in library. Or check www.detonationfilms.com for other free explosions. For the ultimate in explosions, you can buy Sollthar's HD stock footage at very reasonable prices.

You can set the duration by by right-clicking on the object and selecting "duration" near the bottom of the pop-up list. Since it doesn't show if you have a mac or a windows computer, i can only give you this much info. Sorry if you have a mac cause i can't help you there.

Thanks for all this informations, I don't know why it isn't displyed but I have Windows XP.

So I'll try to make the duration longer, and maybe I try a few AlamDV Plugins.

I had a few explosions of DetonationFilms, but I don't think the priceless ones are that good... and for a small test for getting better with VisionLab, I don't need to pay money (even if it's a reasonable price =))

Thanks a lot !!

Hi evr1

I had the same question, I change the duration of the particles on my clip but it still move really fast. I know I can use a NLE, but like in my clip I make the energy ball glow, I couldn't keep a constance glow so I had to use like 5 time the same preset, to optain some how the desire finish I was looking for. Here is wht im talking about.

Particle effects are a whole different process than stock footage when it comes to changing the speed or duration. The speed of the particles is set within the attributes of the emitter, and as many of them are animated to change over the course of the effect, and also have gravity affecting them, just slowing down the effect won't always have the desired result. This tutorial will help you get familiar with the controls of the particle engine, which you will need to properly modify the speed of a particle effect.

Until you are familiar with the controls, it may be easier to render out the effect at normal speed, then import the render as stock footage and change the speed of that clip.
