I am usually good with making effects but cant seem to get this one. Help?

http://www.youtube.com/watch?v=SnooUEuyn_M (skips to 2:03) when Snape blocks Harry's spell.

Reading the HP books as of right now in hopes of finishing the series before the movies (on the 6th) so not sure exactly how to call it....
Thanks for the help everyone!

This effect is maked with After Effects and the plug-in Trapcode Particular. They use a parameter called "CC vector blur" to give a more smooth.
This parameter is not available on the FXhome software.

Hi 2xZProductions,

I'm not really into the whole Harry Potter thing, so forgive me for asking: the dark guy is Snape, right? And this is the effect you are looking for:



?

I guess it should be possible to do this. Especially as this effect is only lasting for a few frames. You might need some stock footage of something smokelike. I'll try a few things and get back to you about this as soon as I know what I'm talking about wink

Have a nice evening,
Helge

or it would create this effect on alpha channel.
smile after the creation of this effect, simply import it as a simple video, placing it directly on the video.

Thanks guys, and yes that is Snape. And yes, that is the exact effect I am looking for. I was thinking maybe about an ink in water, but am not sure yet. Thanks for the help, its quite a difficult effect to accomplish. If anyone has anymore ideas or a more plausable way to create it, please let me know. It will be used quite a bit in the movie. (if it ever becomes a movie).

Hi, I think 'ink in water' sounds great. This is something you should definitely check out. (I bought a small fish tank for things like this some time ago - unfortunately I didn't find the time to try this (yet).)

For now I tried a more digital approach. I rendered a few seconds of fog/plasma like noise using cinema 4d.



Maybe this is something you can use to generate the effect you are looking for. It might not be the same as seen in the Harry Potter trailer but you might still be able to create something similar. Just use the noise as a basis and apply some grading effects in EffectsLab ('Color balance' and 'Edge detect: glowing' worked quite nicely when I had a quick look at this using the EffectsLab demo.)

I noticed (http://fxhome.com/forums/viewtopic.php?t=43368) that there are different composite setting whether the source footage comes with or without an alpha channel. That is why I generated two versions of the noise footage. I guess you are much more an expert than me when it comes to tweaking effects in EffectsLab. So here are the links: (maybe you can combine both to maximize the overall appearance of the effect)

10sec 250frames 800x800px without alpha:
http://dl.dropbox.com/u/6120806/wads_800x800_10sec_no_alpha.zip

10sec 250frames 800x800px with alpha:
http://dl.dropbox.com/u/6120806/wads_800x800_10sec_alpha.zip

Have a nice evening smile

Very nice! I'm really looking forward to seeing this effect in action. If you are going to experiment with this any further you might want to try speeding up the base footage a little. Maybe this will lead to more visible fluctuation within the clouds.

But on the other hand - nobody will ever be able to notice this wink Even the original effect didn't last that long:


Btw. I updated my post above. You will now find the second download, as well. This one does not contain an alpha channel. Because of this its composite method can be set to SCREEN or ADD in EffectsLab. This might prove useful if you should ever need to blend it with any background footage more smoothly.

Hey made this new test.
http://www.youtube.com/watch?v=ahn7K8EaLoc

Used some other stock footage and other blends. The picture is stretched, I know, sorry, but I hope the idea is sort of there...

Feedback? And I know I need some lightning on the entire picture, got it. Any other ideas?

I think this is working really well. Looking at your results this seems to be the right approach for this kind of thing.
Maybe having a real (flashing) light source for lighting the background might also be helpful in order to bring the original footage and the effect together a little more.

If these death eaters are the same things that keep flying around (and damaging/destroying buildings) in the trailer you posted earlier, this looks like something one needs to put a lot of work into.
Did you use the particle engine for this? Seems to me this might be the right choice. If you already rendered anything worth showing - don't hesitate to do so smile

I'm pretty sure you could just use some smoky effects (creat your own if you have to)then let it fade into the Bamf! effect(just change the color)

Ok, hello. I know this topic is slightly old, but I have been trying yet again to create this effect with everything used here, but it has been pretty difficult. If anyone has any ideas then thanks. I have used the particle engine but it has been pretty hard. I wonder if anyone has any moving textures as Helge provided eariler, (I have tried these and have had difficulties) but if not, what else can I do?

I'm not exactly sure which effect you are trying to replicate. Is it the 'person' appearing out of some kind of dark cloud or are you after the black fast-flying cloud thingy?
Maybe you could upload an example of what you have managed to put together so far. I'm sure someone will be able to help you to improve the results.

cu,

I just rechecked the old posts and like I remembered your first attempts on this looked really promising. You said that you "have had difficulties" using the animated textures. Can you describe in more detail why this didn't work out? I still think that this might be the right way to go.

Regarding this link - it seems like the edges or the effect are a bit harsh, which makes it feel strange when its moving so fast. You might try duplicating the effect onto a second layer behind the main effect, and adding a fair bit of blur to the duplicate, to help soften the edges and fill the effect out.

It is not really the effect being bad, its just the lock of it ( in my opinion) I don't think it looks very promising. I want a different look to it that looks nice, and crisp. It is a pretty complex effect, and I am unhappy with the results I have come up with. I don't have any animated textures at the moment ( beside Helge's ) anyways so I have nothing to try to come up with.

Is the youtube video above still the current state of the effect? On youtube you said that you did quite a lot of changes since it was uploaded. Do you have a video of the current version? Maybe this will help to understand what seems to be 'wrong' so far.

Yes I know what it says. What I am trying to say is that I want to completely change the effect, with different textures, different movement, different interaction. This is what I mean.

When I built the textures for the Bamf presets that are available for VisionLab, what I did to create a series of animated textures was basically start out by creating a stock footage clip that could be sliced into frames. I took a variety of smoke stock, which I think I got from Detonation Films, and layered it one over another in After Effects, then remapped the timing a bunch to get the movement I wanted. Then I colored the stock layers to get the final look of the effect. The general concept of this effect seems somewhat similar, so a similar technique might work for this one as well.

By the way, if you use animated textures in VisionLab, you can only use one sequence of textures, so essentially you can import it as stock and have nearly the same control over the look of the effect, without having to worry about creating a bunch of greyscale texture versions of the images.

I think I follow you, but I am limited to some of the cool textures that are found within After Effects. The main ones that would be useful would be Fractal Noise and Vector Blur. These two would really help turn the effects the way that I want them and other stock could be used to enhance lighting or add smoke to the effect. Perhaps you could render out either of these Axeman? smile

I don't think I'll be able to, sorry. Its been years since I used After Effects, plus I'm so busy right now that I don't think I'll have the time. If I find some, I'll let you know, but I don't expect to have a chance any time soon. Sorry man.

Hi -2xZ,
as I don't have After Effects - do you have an example of the "Fractal Noise" you are looking for? I guess, it should be possible to put something similar together some way.

Something such as this:

or

http://1malaysia-innovation.com/wp-content/uploads/image/After%20Effects%202/29.jpg

or

http://blogs.adobe.com/bobddv/files/bobddv/images/velez_ae_disc.jpg

These are cool. They are all made in After Effects but if there are any textures similar. I specifically like the last two, as they look very interesting. These could be transformed into a displacement map and really give some nice looks to the effects.

Hi there,

I just put together a few different animated noise patterns. Each zip file contains 25 frames (600x600px / jpg). If you need more frames of any of these textures just let me know. But as I'll have no access to my computer over Christmas I'm not sure when the new files will be available.

Ok so here is my turn out of effects with the particle engine. Will re-release this again with the textures from helge, once they have been polished. They aren't looking very promising as of yet.

http://www.youtube.com/watch?v=-8Rc42lPAy8 (these effects will look much more explosive when I release the other wand battle we are making - shooting begins after Christmas, and should be around 3 minutes long)

Thanks again Axeman and Helge, but I am still not satisfied. sad
I'll see what I can do with these textures Helge.

I think the effect on the last video you posted was quite nice. I especially liked the way the effect 'faded out'. If I remember correctly you wanted the effect to be more 'crisp'. This is something you might be able to enhance a little more. But I guess you changed a lot - so the last video isn't the current state anymore wink
