One more thing I’m trying to figure out with another expression I’m using with the previous. I wrote the following expression to toggle an Effect Opacity on and off with keyframes. I can’t figure out how to use easeOut to ramp the transition from 0 to 100 and back to 0 (on following keyframe).

try{
m = thisLayer.marker;
i = m.nearestKey(time).index;
if (m.nearestKey(time).time > time){ i--;}
if (i < 1) { i = 1};
i%2*100
}catch(err){1}

Looks good to me. Thanks, your biggest fan (probably not, since you are a rock star).

Thanks. Was going crazy. < > test lol

Currently The odd numbers are pause and I’m starting clip off frozen with marker off top.

My last post didn’t paste correctly. Something weird between Mac and PC text.

try{
m = thisLayer.marker;
i = m.nearestKey(time).index;
if (m.nearestKey(time).time > time){ i--;}
if (i < 1) { i = 1};
if (i%2==1) {marker.key(i).time} else {totaltime}
}catch(err){0}

I understood this, and that is the part I’m trying to figure out. I wrote this after sending the post, but I still need to write something for calculating totaltime of the odd or even marker differences.

try{
m = thisLayer.marker;
i = m.nearestKey(time).index;
if (m.nearestKey(time).time > time){ i--;}
if (i < 1) { i = 1};
if (i%2==1) {marker.key(i).time} else {totaltime}
}catch(err){0}

It would be in the /home directory/library/application support/Adobe/common/media cache (and also media cache files). You can get to the home library by holding option key while browsing the go menu in finder (library will be there in the list.

Note: this is also where after effects will cache by default.

Depending on what you are switching, you can create a precomp with solids labeled for choices and read the results of a layer control. Then you’d only get one of your three choices.

As an example, I made a precomp named “Pre-comp 1” and three layers named “OPT-1″,”OPT-2” and “OPT-3”.

With the following expression I can return the value 1, 2 or 3 to change whatever else.

if (comp(“Pre-comp 1”).layer(“OPT-1”).effect(“Layer Control”)(“Layer”) == comp(“Pre-comp 1”).layer(“OPT-1”)){1};
if (comp(“Pre-comp 1”).layer(“OPT-1”).effect(“Layer Control”)(“Layer”) == comp(“Pre-comp 1”).layer(“OPT-2”)){2};
if (comp(“Pre-comp 1”).layer(“OPT-1”).effect(“Layer Control”)(“Layer”) == comp(“Pre-comp 1”).layer(“OPT-3”)){3};

Thank you for the quick response. I spend around two hours searching for a quick solution. What I have now would probably be easier to manipulate for my current needs. I saw a response you made on paths to someone else stating there is little you can read with expressions on a path. I am running 2014.1.1 and was hoping this would have been updated in 2014.1.2 like the text bounds thing. Anyway, thanks again. I have much respect for your content on creativecow. 🙂
