Building the Heart Monitor

The style of the monitor enclosure you'll build to contain the heartbeat's path is like a relic from the earliest days of such devices. Before you build the monitor, you'll create a sequence of your heartbeat animation so that it loops continuously in the background. Here are the steps:


Create a new composition named Heart Monitor in your Project window's Comps folder, using the NTSC DV, 720x480 comp preset, with Duration 10;00 seconds.


Add the Heartbeat composition to the Heart Monitor Timeline at time 0;00.


Duplicate the Heartbeat layer nine times so you have a total of ten layers.


Select all the Heartbeat layers, and choose Animation > Keyframe Assistant > Sequence Layers. Make sure the Overlap option is unchecked and Transition is set to Dissolve Front Layer.

The Heartbeat Timeline after sequencing the layers


Create a new comp-size Solid layer named Grid that's any color. Make sure the layer is above all the other layers in the Timeline.


Apply Effect > Render > Grid to the Grid layer, and set the effect's Border (grid line size) property to 2.5. Change the color to green.


To smooth out the grid lines, apply Effect > Blur & Sharpen > Fast Blur effect to the Grid layer, and set the effect's Blurriness property to 2.

Settings for the Grid layer's effects


To create a bulge in the virtual glass of your monitor, choose Layer > New > Adjustment Layer, and name the layer Bulge. Since an Adjustment layer only works on layers that are below it, make sure the layer is at the top of the Timeline.


Apply Effect > Distort > Bulge to the Bulge layer. Use these effect settings:

Horizontal Radius: 320

Vertical Radius: 320

Bulge Height: 0.7
