wait what am I talking about

If you want to switch your keyboard shortcuts to use spacebar to initiate RAM preview instead of 0 to do so, that isn’t hard.
NOoooo i have enough trouble in other apps wrongly pressing spacebar for the pan tool as it is, I’d go crazy if it changed in AE 😀

something like this, will change the values to sliders controls.
minblur = 42// warp turns off (these first lines limit the warp so it only happens when the object is moving really fast);
maxblur = 100//warp at highest intensity;
minamount = 0;
maxamount = 500;
// Pick 2 points
point1=toComp(anchorPoint,time-thisComp.frameDuration/2);
point2=toComp(anchorPoint,time+thisComp.frameDuration/2);
// Find the vector between them
delta=sub(point1, point2);
X=delta[0];
Y=delta[1];
// Now find the length
bluramount =Math.sqrt(X*X+Y*Y)/4;
ease(bluramount, minblur, maxblur, minamount, maxamount) -
OK I’m getting somewhere, learned something about calculating distance between two points. 🙂 This expression – modified from one on https://www.jjgifford.com/expressions/geometry/length.html – seems to be getting me there.
// Pick 2 points
point1=toComp(anchorPoint,time-thisComp.frameDuration/2);
point2=toComp(anchorPoint,time+thisComp.frameDuration/2);
// Find the vector between them
delta=sub(point1, point2);
X=delta[0];
Y=delta[1];
// Now find the length
distance=Math.sqrt(X*X+Y*Y);Not quite got my head around whether I’m even getting ‘velocity’ per se but it will work for my purposes once i add controls to limit the amount and threshold.
Thanks again for your help 🙂

Thanks for the pointer. I copied that part of the expression from a tutorial so I shall have to actually learn how it quite works ha. 🙂 Pasting the direction expression in there actually kind of ‘works’ tho gives weird results presumably due to the angle calculating stuff. Hopefully I can get my head around it!

Thanks very much for the quick reply!
That works a treat for the direction expression thanks, but I’m still not sure how to apply toComp to the warp amount.
I tried:var vx=toComp(anchorPoint.velocity[0]);
var vy=toComp(anchorPoint.velocity[0]);But that gives me “Bad argument: First argument to toComp must be a vector of length 2 or 3.”
Will keep trying to figure it out. 🙂

That’s been done with video feedback. Get into the arcane mysteries of the CC Time Blend FX plugin, you can make all sorts of psy fx including pretty realistic video feedback. It’s not AT ALL self-evident how to even make it do anything whatsoever so google some tutorials. You’ll need to introduce some noise and yeah probably some colorama as mentioned above, and some echo maybe?
In order to very slight scale/rotate each frame (which you’d need to do to get that kind of swirling feedback going) I found that I had to do weird workarounds because not all effects acutally work with Time Blend FX; I think when I tried it a while back I ended to having to do something like use a single-card ‘Card Dance’ effect because the basic Transform effect wouldn’t cooperate…?
Anyway yes Time Blend FX or just get a camcorder and point it at a tv.

Yeah that was pretty uncalled for on my part to say the least, sincere apologies to Dave.
and yes I do realise that.
and Ridley Walker is a great novel!

I explained all that, I even made a diagram with.black metal dingbat font. AND I have pretty much answered my own question anyway. I was waiting for a bus and conceptualised the whole shadow map resolution thing; naturally if the shadow map is a specific size then a camera more zoomed in will be more low rez.
