I have some question about the bullet trail presets. Can the origination and destination points be edited to suit your footage? If this has been covered can someone please direct me to the thread.

Thanks,
Brent

Yeah, I think they do.. However I'm afraid your EffectsLab will not work with them, since you own EL DV and not Pro... Displacement map is a feature avelibale only to Pro. (And VisionLab of course). Sorry to bring you these bad news, but I'm sure that in time creative FXhomers will come up with a bullet trail-preset for DV.. In the meantime, you could come up with a solution using this method... Just form the shape as a bullet trail.. If you get to know the app I'm convinced that you can make this work! Good luck! biggrin

Sounds like I've found that reason to upgrade. I had planned to anyways. Is it as simple as changing the start and ending point somehow. The tutorial, which is of course not for EF anyways seems a bit involved.

Can anyone confirm that upgrading to pro version of Effects lab will allow me to adjust the start and end point for the bullet trails preset?

I can confirm it. I created two version of the trail, depending on if the bullet is coming towards the camera or moving away from it, but on either one, you can just go to the first frame and move the start point to anywhere you like, then do the same for the end point. It's quite easy.

Just a quick question: the bullet trail preset is great, but I seems its impossible to adjust its speed? As in using the speed tool?

It's easy to adjust the speed. Just set the length of the effect to as long as you want, then move the last keyframe to the last frame of the effect.

That's how I usually do it, but this preset has a key frame on like every second frame. So I'm not sure how to deal with that...

Oh... Well, you could just make your own then... Look at the settings on the preset, and try to learn how it's done, then make your own to fit your needs! wink Hope you'll work it out!

Axeman, your suggestion worked like a breeze. One thing, i'm interested in have a bullet shoot straight across my screen from left to right, which I've made it do, but of course now the shape of the displacment bubbles isn't quite right. I think a horrizontally traveling version of this preset would be most useful if you find yourself in the mood to update it. This looks really great! I can't wait to get home and put it on my clip.

Regards,
Brent

I used the Bullettime preset in this little test clip about halfway through. I think I need to slow it down a bit yet.

Hey,

If you're referring to the attempt at matrix style punches at the end, it's easy.

now in this case the footage was a bit too dark to get the effect I was going for but in an nutshell it goes like this.

Have your actor/actress put a slight pause at the end of every punch except the last none. Then pull your footage into your compisiting tool, After Effects or VisionLab. Put the source footage down and move your cursor slightly forward and put a copy of the footage. Make this copy an opacity of %38 or so. Repeat this process as many times as you want copies of the blows.

Does that make sense?

I actually had a version of this preset from the side that I did at the same time as the other two, but I never got it quite right, so it hasn't been submitted. If I get a chance in the near future, I'll look into trying to finish it.

As far as changing the speed of the effect, it is always gonna be a bit tricky. As mentioned, this effect requires keyframes in radip successoin to turn the emitter on and off, so you don't end up with too many ripples. So there are a few things you can try.

If you want to slow down the speed at which the ripples appear, the only thing to do is manually move the keyframes farther apart. Slow and a bit of a pain, but the only option, really.

If you just want to slow down the speed at which it crosses the frame, it is a simple matter of moving the start and end points. The distance across the frame that it travels from start to finish is what sets its speed of travel, so by moving the start and end closer together, you can slow it down. If you need to make the effect last longer, drag the out point for the effect to where you need it, then select a big chunk of the keyframes and copy and paste them to fill in the new section.

New Presets Option

I look forward to the new versions cause this is probably my favoriate group of presets available now. Really excellent work!
