Thanks.. that’s opened my thinking more on this.

I did actually also find I could achieve it by using Math.cos instead of sin in the formula. but again this limits it to beginning at the position furthest from camera, so I like the precise control of the phase degree… Thanks

I’ve utilised the expression included in here (lifesaver) to animate the z position so that titles pump in & out from the camera in line with the BPM.

however I’m also having the same issue which I think Armand is referring to ..

I have a 4 bar loop of music at 130 BPM. Using the expression makes this loop very close to perfectly.

The fist beat of the first bar is at 00:00:00:00 in my sequence. But wen the animation of the title in z depth begins it is around mid way through a cycle of the sin wave, rather than beginning at the bottom or top of the wave. As a result it isn’t pulsing in sync with the other elements I have looping in the sequence..

Is there a way to control the beginning of the sin function so it begins at 00:00:00:00?

Cheers

Toby

bpm = 130;
mag = 500;
freq = bpm /60 /2;
z= mag * Math.sin( 1 * Math.PI*freq * time);
