One of the cool things about tracking is that it gives you the ability to place objects together, -in motion – by your own design
big deal. Well, actually it is. It’s one thing to be very talented with your layer control and blending but the only way to add objects of your own choice, of your own design to an object in motion – IS with the tracking ability to apply to your new object.
You can dress things up, you can have humans fly with the birds, you can have prehistoric beast riding atop a railroad train but you need to be able to apply the position tracking data and
depending on whose joining whom, you need to be able to extract your image from it’s backdrop.
That’s where Mocha comes in. An entry level version of Mocha tracking is included with After Effects CS4 and their site provides several tutorials on different aspects of tracking and tracking applications.
I like using real life effects with my effects – so when I wanted to jazz up the sun – adding a sunrise to this logo, I just happened to have some beautiful sunrise footage from Gulf Shores – beautiful. I actually named my clip ‘liquify’ because you could practically see the sun melting into the gulf as it was rising above it.
It turned into an interesting blend of odd tools because starting with my ‘Real sun’ meant calming it down with Mocha tracking. I’m still cutting my teeth on Mocha but basically, you describe the shape you want to stabilize, track it, check the stability as you go and once you are comfortable with the tracking, export your tracking data, paste into After Effects. The only caveats I encountered is, you can track position, scale, rotation, and shear and in this case, a fairly straight ahead view of sun that simply bobbed with my handle. The ’stabilization’ required I paste these new tracking points against the anchor point in AE.
Once you have a stable sunrise, apply a mask in a copy of your composition. If you try to mask your movie, the mask will jump around with the adjusted anchor too – I applied a mask on a solid layer in same comp to see it work – to see movie for masking application, on new solid to see it remain in place.
To bring in a masked alpha image however, you need to create comp from this one, then copy mask over to this new comp that is … a composite of all the elements so far. It sounds a bit complicated, there may be a simpler way but you end up with stabilized, masked comp that you can apply to your ‘real’ job, the logo you are creating, and there
start having more fun. Like applying some sunlike flare and brilliant light … from Knoll light factory. I know of no better way but to experiment a bit, and that’s exactly what I did. I found a ‘desert sun’ flare that blended quite nicely as I let my ‘real Sun’, melt with Knoll flare, into the Illustrator sun logo.
A little bit of work, quite a bit of Fun !
we’ll share more detail on this excercise in stabilisation – tracking points primarily but pasting only the anchor to maintain the visiual backrop while focusing the center of the movie, this beautiful sunrise,
but tracking the data, minimizing keyframes, takes this shaky first time effort to a reasonable steady ride.
As you watch the phase of an object changing in nature, whether it be a sunrise, a bird fly, or a cloud go by -
a little tracking can go a long way helping you commit this to a viewer friendly video.
I like this morning moon, still crisp and light enough tostand out against the sky but with dawn creeping into the sky, the moon glow has a very different, an irridescent glow thang
Planar tracking has many different applications – besides replacing footage, a favorite is stabilization.
How many times does our camera jiggle, something get in the way, not to mention normal motion, traffic, other images in our view.
Tracking can help us focus and distinguish our subject, and create ‘cleaner’ composition.
