How to create sine curve
Hello All,
How can I create a sine wave, much like a brain wave, using AE 6.0?
Thx

Make a mask with 2 points one at the far left outside of the frame; the other far right outside — make it perfectly staright
RENDER–>STROKE the mask (make sure you set PAINT STYLE OF STROKE to ON TRANPARENT).
Add WAVE WARP — wave type SINE
adjust and animate to taste using WAVE SPEED and PHASE….

You could also do this via expressions and the write on effect…
Try this expression for the brush position of the write on effect://begin
amp = 100;//Height of wave in pixels
freq = 2;//Oscillations per sec
beginTime = 0;//in seconds
endTime = 5;//in secondsy = amp*Math.sin(freq*time*2*Math.PI) + (thisComp.height/2);
x =linear(time, beginTime, endTime, 0, thisComp.width);
[x,y]
//end~Colin

If you don’t need it still and want it to animate like an oscilloscope,
Find yourself some audio of a very deep sine wave or maybe one that is changes tune a little bit and then use the “Render->Audio Waveform” Filter. -

This idea already appeared somewhere in the cow forums, but thanks for posting.
On a side-note, it is hard to understand why the Write-on effect is so desperatingly s-l-o-w when lowering the (temporal) brush spacing. 0.001 corresponds to 1000 particles/sec, it is not that much. Paticular can handle 1000 x that and doesnt freeze like Write-on…
