layer in/out based expressions
i am doing 4 1-minute long photo sequences for a friends doc, and each consists of a bunch of photos i am doing a simple fade up and unblur at the beginning and reverse at the end. trying to make it like an old school slideshow.
i have the opacity and blur parameters animated the same way on each layer
would there be a way to have an expression that basically says, at layer start, opacity = 0, blur equals 10, and at frame 5 (of layer trim), opacity = 100, and blur equals zero
likewise at 2 frames before layer end, same settings, and at the last frame of the layer, the first settings i had (invisible with blur.)
if easing would be possible, even cooler. I feel like this is possible, just beyond my skill at expression writing.
thanks in advance.

Something like this should work for opacity:
fadeInFrames = 5;
fadeOutFrames = 2;
startVal = 0;
endVal = 100;if (time < (inPoint+outPoint)/2){ linear(time,inPoint,inPoint + fadeInFrames*thisComp.frameDuration,startVal,endVal) }else{ linear(time,outPoint - fadeOutFrames*thisComp.frameDuration,outPoint,endVal,startVal) } and this for blur: fadeInFrames = 5; fadeOutFrames = 2; startVal = 10; endVal = 0; if (time < (inPoint+outPoint)/2){ linear(time,inPoint,inPoint + fadeInFrames*thisComp.frameDuration,startVal,endVal) }else{ linear(time,outPoint - fadeOutFrames*thisComp.frameDuration,outPoint,endVal,startVal) } Dan
