For example, if we're tracking a car that drives behind a pole, the pixels we're tracking are blocked. This calls for multipart tracking.
The basic idea behind multipart tracking is that we select another area to track, without interuppting the track or moving the attach point. Adobe has a help page dedicated to Tracking and stabilizing motion. Here's the part that shows the subtle differences in how the selection tool appears when moving various parts of the track point.
In this exercise, you'll show you can track an object, even though it moves out of the frame or is blocked. You'll need 1 piece of media from the Meyer DVD:. If you have the Meyer book, follow the instructions in the Multipart Track tutorial on page from Chapter Otherwise, follow these instructions:.
Thursday If you've got a small or slow laptop, use Blue Dance clip, found in this 8 MB zip file :. After Effects has some excellent built-in keying tools- but the footage should be lit well and recorded with a codec that has good color space.
Most HD video codecs are fine to use for chroma keying- but some codecs have more color information than others , It's important that the background is evenly lit. Place your chromakey footage above the background. You will use the keying tools to remove the background to reveal the layer underneath. Garbage matte aka junk matte - Often when footage is captured for chroma keying, there are areas not masked or covered by the blue or green screen material or paint.
There might be rods, wires, edges of green screen backdrops, etc. These visual artifacts are typically outside of the subject's area of motion. Because they aren't the uniform blue or green required for color keying, we use what's called a garbage matte to get rid of them.
In AE it's easy to use the pen tool to make a mask that serves as a garbage matte. To overlap, MediaSourceReferences must be on separate tracks. It can often be quite difficult to visualize what's happening on a playlist. Fortunately, there is a static method on the VideoCompositor which will render a visual representation of a playlist to a canvas. The visualization will appear as a purple bar below the video.
This will be useful later on once we start adding more tracks to the playlist. We're now going to introduce two important concepts: parallel tracks and effects. To introduce these concepts, we're going to need more source material. Download a suitable image and place it in the working directory of project with the name "image. The playlist visualisation below the video has a new track -- visualised as a green line. However, running the above playlist will make no apparent changes to the rendered output video.
The video hasn't changed because tracks are rendered in order. The track with the highest index will render first, and the one with the lowest index will render last although a track with index 0 will render on top of everything. This means our Shia LeBeouf video will be rendered on top of the static image.
This will apply a greenscreen effect to the Shia LaBeouf videos, causing the green pixels to be transparent allowing the underlying image to show through. Let's add some interactive graphics behind Shia. To do this we will add a new track to the playlist, but the MediaSourceReference will be a little different. Rather than passing in a source string, we'll pass in an already existing HTML5 canvas element. The reason the canvas is set to display style none is because we want to hide the DOM element and have it only displayed via the video compositor.
When we pass a DOM element rather than a src string to the video compositor it will render both in the page as a DOM element and via the video compositor. If it's resource intensive and you only want it to exist in the browser for the duration of time it's being displayed by the video compositor, you can attach a listener object to the MediaSourceReference's id using the VideoCompositor.
This will provide callbacks for when the MediaSource needs to be loaded, played, rendered and destroyed. Next we will get a reference to the new canvas element before the playlist is set, and set up some animations using requestAnimationFrame. Video Audio icon An illustration of an audio speaker.
