Push In+Out?
I’ve been trying to modify the After Effects’ “Fade In+Out – frames” Animation Preset to be used with Position instead of Opacity (I’m calling it “Push In+Out”). With my skills I just get a lot of errors. 🙂 Maybe someone could give me a few pointers.
What I’m trying to achieve is: starting from the Layer inpoint, the layer positions itself in 15 frames from a pre-set position (say from the bottom of the screen, just outside the visible area) to another pre-set position (say in the centre of screen). And 15 frames before the end of the Layer outpoint the movement would be vice versa, from the centre of the screen to the bottom.
Would this be difficult/possible to do with the help of inPoint and outPoint?

Something like this should work:
moveFrames = 15;
offScreen = [-width/2, thisComp.height + height/2];
onScreen = [thisComp.width, thisComp.height]/2;moveTime = moveFrames*thisComp.frameDuration;
if (time <= inPoint + moveTime){ ease(time, inPoint, inPoint + moveTime, offScreen, onScreen); }else if (time < outPoint - moveTime){ onScreen; }else{ ease(time, outPoint - moveTime, outPoint, onScreen, offScreen); } Dan -
A little tweak to the last version – this one lets you have different entry and exit points and gets rid of a little uneccessary code:
moveFrames = 15;
onScreen = [thisComp.width, thisComp.height]/2;
offScreen1 = [-width/2, thisComp.height + height/2];
offScreen2 = [thisComp.width + width/2, thisComp.height + height/2];moveTime = moveFrames*thisComp.frameDuration;
if (time < outPoint - moveTime){ ease(time, inPoint, inPoint + moveTime, offScreen1, onScreen); }else{ ease(time, outPoint - moveTime, outPoint, onScreen, offScreen2); } Dan -
Thanks, this works great!
Next I’ll try to modify it to work with some other properties and offset the timings a bit. Will keep me busy for a while. 🙂
