auto-animating speed control on a 2 dimensional parameter
on Sep 28, 2017 at 8:45:41 pm

the other day Dan kindly pointed me to a way to auto animate a parameter using an expression like this

spd = (500);
value + time*spd

Now I'm trying to use this idea applied to the XY coordinate param of a filter and I'd like to be able to control both the X and the Y separately (a filter XY coordinate cannot simply be broken into separate dimensions like the Position of a layer can or I would just do that...)

I know how to set each part of such a 2 dimensional coordinate param separately with an expression like this

tempX = effect("Slider Control")("Slider"), tempY = effect("Slider Control 2")("Slider");
[tempX, tempY]

and although I've tried several things in a trial and error attempt to do it, somehow a solution for doing it with the auto animation and speed control is eluding me (and now it's getting late in the day : )....

any hints much appreciated - thanks

Something like this, probably:

spdX = 500;
spdY = 200;
value + [spdX,spdY]*time
