Imitating a film projector with FPS control
Posted: October 19th, 2005, 8:13 am
Add the Distort->Offset plugin to a piece of footage and add this expression to the "Shift Center To" property. If you want a black line or film frame around the footage, pre-comp and do it there.
You can also add a slider to the fps property to animate it and simulate adjusting the framer on a projector. Add an Expression Controls->Slider Control Effect to the layer and change the expression of the "Shift Center To" property to this:
Finally to add some flicker, add this expression to the Opacity:
thanks to goldomega for the reset part of the expression
Code: Select all
fps= 24;
t=time * fps;
move= t * thisComp.height;
reset=Math.floor(move/thisComp.height);
moveReset=move-reset*thisComp.height;
[thisProperty[0],thisProperty[1] + moveReset]
Code: Select all
fps= effect("Slider Control")("Slider");
t=time * fps;
move= t * thisComp.height;
reset=Math.floor(move/thisComp.height);
moveReset=move-reset*thisComp.height;
[thisProperty[0],thisProperty[1] + moveReset]
Finally to add some flicker, add this expression to the Opacity:
Code: Select all
wiggle (effect("Slider Control")("Slider"), 20)
