Hello Again gang!

I would like to request a Ghostbusters II proton beam look-a-like efect.

I know we already have the Ghostbusters' proton beam available, and it looks awesome, but I need the Ghostbusters II type effect. It has MANY differences between each effect and the available one is GB I style.

I created an animated GIF (with 1.4Mb) to show the effect.



Wait it to load. It will take some time, depending from your internet speed.

To copy this image to your hard disk, just right-click on image and choose "Save Image As..." and find a place in your hard drive.

If you could develop this plugin effect, let me know! I need it to my AlamDV and I guess it will be an AWESOME addition to worldwide AlamDV's community.

If you need an AVI, MOV or MPEG video file, showing this scene with high resolution, let me know via e-mail (get it at my profile) or Private Message (reach this option in topic's bottom area).

I'll digitalize the sequence, create the video file and send it to you, by e-mail or send you the link to be downloaded by you.

Thanks in advance!

yeah, just wait for digigrade and use the plugin and grade it for the GB2 color. It all looks tons better if you actully use liveaction lighteffects on the set and combain them with the effect.

Guys,

I'll try to report some details you couldn't see first time looking, because I was studing this effect for some time. So, I'll try to describe what I noticed in the effects, separating them as "Ghostbusters I Beam", "Ghostbusters II Beam" and "AlamDV Ghostbusters Beam".

"Ghostbusters I Beam" has a much more complex electric lightning over the orange base beam. It is much more twisted lightning, that runs from proton gun's muzzle to its target.



"Ghostbusters II Beam" hasn't the twisted electric ligthnings, but has some random moved lightnings, that runs from gun's muzzle to target and disappears. Some seconds (or frames) later we have another electric ligthning starting to run.

A running electric ligthning on screen


Now, its almost in target's point.


The "base beam", without any electric ligthning.


A new electric ligthning starting to run, on gun's muzzle.

NOTE: The frames I show above AREN'T in sequence, in the movie. I just exported some frames to show what I say. This is why beam's curves are smooth (what doesn't happen in movie's effects).


"AlamDV Ghostbusters Beam" has a PERFECT base beam, but its electric lightning is different from any Ghostbusters' proton beam effects.

And beam's curves are very smooth and only up to down. Movie's beams has stronger curves, some almost linned periods and returns to oscillate hard. Check it out!


I hope you could see the differences I saw and could make a more accurate effect (like a Ghostbusters' beam - V.2.0). smile

Thanks!

Is there a reason that you have to get the effect to look EXACTLY like the one in the second film? I mean, if the effect looks good, and is recognizable as a Ghostbuster's Proton Beam, then it seems to me it is doing its job. If there are subtle differences between your effect and the one in the original film, that is a GOOD thing.

Why do you think the proton beam changed from the first to the second film? Because there is more than one way to create the effect. There is more than one way it can look, and still look good. If the original filmmakers were willing to change the effect somewhat, while still retaining the basic elements, then I encourage you to do the same. Keep all of the basic elements, then alter them however you want to get an effect that will be distinctive to your movie. This will also give you more freedom to play with the effect and alter it and possibly come up with something that looks even cooler.

Hello Axeman!

I'm just trying to help AlamDV's community to get a more accurate movie effect. Just that!

I'm very sorry if you or anyone related with this effect feels anger or sad with me, but I was just trying to point some differences from the effect we have to the movie's, in hope to have it better.

It was not my idea to destroy the available effect's honor or merits. I just want to IMPROVE the actual effect's quality and help its creator to raise his name in AlamDV's community.

I was thinking this forum is to have ideas discussed and, if it looks good, improved and created. But if not, please, accept my apologies.

Thanks anyway.

Im sure no one here is angry with you, they were just pointing out that there was no real need for someone to take the time and effort to make a near identical plugin to one which exist. As Axeman said, it is a good thing that it looks slightly different from the one in the film, as long as it looks good and people know what it's supposed to be, then it doesn't have to be identical.

MGW,

I'm sure none here is anger with me. I just want to present an idea to make an upgraded version of this effect. Nothing more.

Why loose time to make it almost identical? Simple! Movie accurate! I guess each AlamDV user is happy because its effect's quality.

And this pays the effort to develop a "2.0" version for this effect.

If I could know how to create a transparent background for glowing effects, I would try to develop this effect, but I don't know how to create any effect.

If you (or someone else) could offer me a tutorial to create effects, that allow me to make glows without problem in its transparency (without the black outter line I have when I try to make it), I'll do this effect and Ghostbusters' trap too.

Let me hear from you.

I am definitely not mad at you, or upset with you, or anything of the sort. Sorry If I gave the wrong impression. If you want to create the EXACT same effect as in Ghostbusters II, there is absolutely nothing wrong with that. The point I was trying to make was just that an exact match isn't necessary. As a general rule, effects should exist only to further the story. They help convey to the audience things which are happening that you could not do practically on set. In this case, conveying to the audience that the Ghostbusters have Proton Beam guns with which they can shoot ghosts. All I was trying to say is that the effect can serve that purpose 100% without matching the original film effect exactly. It does not have to be identical for the audience to understand what is going on.

Also, I find it to be a lot more fun to create new effects than to exactly replicate someone else's, but that certainly does not mean that you can't try to get a perfect match for this effect. As far as creating the effect yourself, there are a few stickys at the top of the Plugins forum that deal with this.

This one is on creating Alpha channels and transparency in Photoshop.
This one covers the same topics, but in Paint Shop Pro.
And this one covers the basics of building plug-ins.

There is also a more extensive documentation of the Plugger and all of its functions in the AlamDV manual. Take a look at those, and if you are still having difficulty with it, feel free to ask me about it, and I'll help you out where I can.

Axeman,

I thank you and be sure, I'm not sad.

I don't own AlamDV's manual, but would like to. So, if you know where to download it, let me know!

I'll check the links you reported and will try to make some effects.

Thanks again!

Axeman,

How do I create an image, with transparent background and outter glow over it? I mean, I create an image but when it opens in AlamDV, the glow appears with a black external glow before it goes transparent.

I'll try to simulate the image below:



Note the black glow outside the red glow from the laser.

How can I fix it?

Thanks

The AlamDV manual comes in either the Standard Installer or Developer Installer., so you might already have it. Unless you downloaded the Minimal Installer, which is the only one that does not include it. I don't think there is currently a download of just the manual available.

Now on to the probem of the black halo. I remember having this problem once upon a time, too, so I know exactly how to fix it. The problem here is that you are trying to feather the edge of your effect in BOTH the RGB image and the alpha channel. The solution is to feather it ONLY in the Alpha Channel. Take a look:



The left side is the RGB, the right side is the alpha channel. Notice how the RGB image is completely, solid red everywhere that the transparent parts of the alpha channel would cover it. The soft edge of the alpha channel will create a soft edge for the effect, but since there is no black under it, no black will show through. Make sense?

I left a bit of black around the red in my sample image there, but really it is easiest to just make the whole RGB image a solid color (in this case, it could be entirely red).The only exception is if the effect is white. Then you need to have a black border around the whole thing. Just make sure it is beyond the edges of your alpha channel.

Azeman,

Makes sense, yes. I'll try it to see how it will be in final result.

Thanks a lot!
