So you’ve done all the hard work. All you need to do now is use a duplicate of your green line layer as a track matte for another layer. I’d be tempted to create a pre-comp with the red and black areas and include the white line too. Then this layer will only be visible when exposed where the green line is.

You’re going to need to hide a transition (fade) from one shot to another during the camera move. A simple morph can help with this.

Chris Zwar’s morph tutorial might help: https://library.creativecow.net/articles/zwar_chris/morph.php

I can and will after the weekend, but found the offer today and I like to plan 🙂

Not infront of my computer right now, but could you apply the effect to an adjustment layer, then using the tracking key frames to move that layer?

Hi Steve,

You’re quite right about the green screen. I only added in the background to demonstrate that it was keyed out. I’d never export that with green in the background.

I’d fashioned a cardboard surround for the front, with the phone inside and off centre. Didn’t spot until editing that underneath the surround was showing up. I also totally missed that I was creating a line of bubbles on the inside of the glass, each time I a bucket of water in. Eventually spotted it and started wiping it down.

I think I’m also going to have to invest in some lights. And yes, a boat load of salt ☺

Hey Mark,

Wow thank you. I love that movie and that’s a really cool insight. To be honest, I’d assumed that shot was footage of a real plane.

As I mentioned in my blog post, I’m not happy with my final version, but I learned about some features of Element 3D which were new to me. The counter measures were most disappointing (as stills they always liked fine) and probably what started my brain ticking over about cloud tanks.

I ordered a couple of inks and they arrived yesterday – so I’ve had more fun with the water tank. I set it up indoors this time, with a little distance from a clear white wall. I tried a few lights, but didn’t have any LED lights to hand with enough power.

I used the ProCam 5 app which gave me more control over the camera.

I did try Steve’s suggestion of adding salt to change the density to get billowing earlier, but looks like i didn’t add nearly enough.

Here’s a brief video I’ve just put together:

Experiments with a Cloud Tank

As you’ll see, I wasn’t draining the tank each time. Maybe I’ll get good enough at this to make some stock shots, but for now it’s about learning the medium. Also, I forgot each time I had a clean tank to set the focus manually, so the auto focus kept screwing things up! Still, it’s a lot cheaper than paying for a high speed camera.

Thanks again for everyone’s advice. When I next get a chance, I’m itching to try dual layers and also smoke rings.

Don’t forgot the waterproof motion control rig.

The shots flying through a tunnel of paint and moving around the vortex are hypnotic.

Thank you everyone, some great advice.

Steve – sounds like you had it down to a fine art. Currently my wife is hoping this is a weekend fad, but I really want to try out all your build suggestions ☺

Dave – The phone I have can shoot 240fps at 1080p, I also rewatch the video and spotted they used water soluble ink. I’d got the wrong end of the stick and grabbed paint. I wonder if that makes a difference.

If I do get anything usable, I’ll share it here.

My best guess at approximating this would be to use CC Particle World.

1. Create a nested comp with a letter per frame. You can use a single layer and keyframe the source text
2. In your main comp, add CC Particle World to a layer
3. Set Producer > Radius X,Y & Z to be between 1 and 2
4. Set Physics > Velocity to 0
5. Set Physics > Gravity to 0
6. Set the Particle Type to be Textured Square and use the letter comp as the Texture Layer
7. Set Particle > Texture Time to Birth (I think)

You’ll have a bunch of letters in 3D space.
