9:40 Attendance

9:45 Motion Tracking Showcase

Let’s take a first look at your motion tracking projects. The goal of this project was to get you more comfortable with the deep features of after effects. Motion tracking makes for much more interesting digital compositions.

Let’s see how you did.

Add to the discussion and provide constructive feedback.

10:35 Rotoscoping and using the Rotobrush tool in After Effects

What the heck is rotoscoping?

Rotoscoping is simply masking out something in your shot that just doesn’t belong. Simply put, rotoscoping is selecting moving footage over time and blocking it out.

Rotoscoping explained – direct from Adobe….

Rotoscope animation describes the process of creating animated sequences by tracing over live-action footage frame by frame. Though it can be time consuming, rotoscoping allows animators to create lifelike characters who move just like people in the real world.

The technique of rotoscoping also made the lightsaber possible.

To create these visual effects in the original Star Wars films, animators drew the color and glow of each lightsaber over the sticks the actors held on every frame in which they appeared.

In After Effects, there is a very powerful tool – the RotoBrush.

11:35 AE Audio Visualizers

What happens when you take some beats, adjust settings for frequency and amplitude and combine them with a visual effects software? You get some really nice audio visualizations.

Audio visualizers generate animated imagery. The imagery is usually generated and rendered in real time and in a way synchronized with the music as it is played.

Super Secret Magic Sauce Code (I’ll explain, don’t worry)
value + (comp(“Music”).layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”)) / 5

Above is an example of an expression. We can pickwhip any (and I many any) effect or setting that has a stop watch to the audio slider. The options are endless, really.
