How Do You Do a Sci-Fi Turn On Effect?

Postby maxvit99 on 09/17/2015, 11:37 pm

Hello, I am trying to make a sci-fi fade/turn on where a HUD grows, turns, and also flickers to turn on like in movies. How is it done (wiggle(value,value) in opacity and scale up looks fake to me)? Thanks, Max

Hi maxvit99, welcome. If you want to have total control you can keyframe exactly what you want. I'm not sure why you are using a wiggle expression?

Hello, the whole effect looks really fast and random to me. I am sorry if this is a totally stupid question, but I am new to animations and after effects.
I would keyframe it if I knew what the effect is made of (what to keyframe, i.e. opacity, rotation, scale, etc.).
I may have been too vague so here are a few examples of it: http://videohive.net/item/cybertech-hud ... k/10581330
(At 3:13, 3:36, and 3:49, but the whole thing has some other cool ones.)
I am basically trying to create these cool and really sci-fi HUDs, and these are what I am trying to recreate. I found some tutorials here and on other sites on it, but none of them seem to explain how to make it turn on in a really cool and appealing way.
Hope you guys have some ideas/suggestions. Thanks, Max

Hi Max, there's a lot of different things going on there. As far as I can work out one of the most basic thing is that the elements draw on, they're not usually scaling up. Perhaps if you look at the Stroke effect it could give you a start - draw paths/masks on a solid, tick the All Masks box and then tick Stroke Sequentially, Paint Style On Transparent then keyframe either the beginning or end amounts to get the drawing happening. You can use several layers to build up a more random effect. Add a couple of other pieces which move into position etc. Add an Adjustment layer on top and add the Strobe Light effect, set the Strobe to Makes Layer Transparent, Random strobe 100%, duration and period very low (but different lengths), etc and shorten the layer to only have it when you want it. That's perhaps a few things you could play with. Others may have other thoughts.

Hello, it took me a minute to figure it out, but I got it! The Strobe Light effect is really cool and it is basically a way to make it flash without actually keyframing it manually! So cool!

I have a few questions, though:
gregalan wrote:You can use several layers to build up a more random effect. Add a couple of other pieces which move into position etc.

What do you mean by this? What other layers should I add to make it more random? And are you referring to pieces that are not part of the design, as in to add a few dots/arrows/lines/grids/etc. that move in? Would I fade them in? Should they scale up?

Also, this was not part of my original question (I thought the being drawn effect is made by masks, not strokes), but it adds to my bag of tricks and makes my life easier, so thanks. I was originally referring to when (for example at 3:13) the HUD grows from the center (or at least it seems so to me) in a more organic way that just scale up from 0% to 100% keyframes. Did they do it by keyframing every frame and spending hours on it? Or is there an easier way out? Thank you so much, Max

Opacity 0/50/0/70/0/100 in short intervals and you should achieve this flicker effect. The scale effect is achieved by playing with both the keyframes in the graph editor. I am not sure I understand what you are asking :shock:

Hello, I did not know about the graph editor. It is really cool! Thank you!

If you have say 10 masks making up your HUD and they draw on in sequence you could cut and paste 5 of these masks onto another solid, add the stroke effect and change some of the settings so that instead of the 10 lines drawing on one after the other, there are two sets of 5 drawing on at almost the same time but with some variation - perhaps coming from different directions (the beginning keyframed in one set and the end keyframed in the other) + any other variations that the effect will allow.

Other pieces moving into position are as you describe, arrows etc. quick fade up then reposition, scale up/down - it's having a variety of different things happening which makes it look interesting. You can also use the Pan Behind Tool to change the place where things scale up from ie: it doesn't always have to scale from the center it can scale from the bottom or the side - or from a position totally away from the object - each gives a different look and feel from the standard scaling up from the center.

Hello, that is exactly what I wanted! Thank you so much! Now it does not look so difficult to do that kind of thigs to me!
