Oscilloscope Trace

Add it to your video

It runs for 6 seconds at 1920×1080. Paste this into your composition:

index.html

<div
  data-composition-id="oscilloscope-trace"
  data-composition-src="compositions/oscilloscope-trace.html"
  data-start="0"
  data-duration="6"
  data-track-index="1"
  data-width="1920"
  data-height="1080"
></div>

Move it in time with data-start. Put it on a different timeline row with data-track-index. See data attributes for the rest.

Variables

Every one of these has a default, so the piece works untouched. Set the ones you want to change on the element:

Variable	Default	Accepts
`waveform`	`sine`	`sine`, `square`, `triangle`, `data`
`frequency`	`12`	0.1Hz to 200Hz, step 0.1Hz
`amplitude`	`3`	0.1div to 4div, step 0.1div
`persistenceMs`	`100`	1ms to 1000ms, step 1ms
`phosphorColor`	`#5dff8f`	color
`sweepRate`	`5`	0.25sweeps/s to 60sweeps/s, step 0.25sweeps/s
`dataSeries`	“	string

Set them with data-variable-values on the element that mounts it. These are the defaults, so this behaves exactly like the preview above until you change one:

<div
  data-composition-id="oscilloscope-trace"
  data-composition-src="compositions/oscilloscope-trace.html"
  data-variable-values='{"waveform":"sine","frequency":12,"amplitude":3,"persistenceMs":100,"phosphorColor":"#5dff8f","sweepRate":5,"dataSeries":""}'
></div>
