Multiple in and out points on a single item on timeline
I want to make something blink. If i adjust the in and out points I can make it visible only when I want which is fast and easy. Question is, can you have more than one set of in and out points on a single use of an imported object? Or is the only way that way to make lots of duplicates and space them out? I know I could do it with lots of opacity key frames on the single item, but it seems in and out points would be faster and easier

i don’t know of a way to have multiple ins and outs for a single clip/layer/comp, but the easiest way may be to just use hold keys in the opacity. create 2 (0% and 100%), then you can duplicate those and paste them where you want them…
if it loops, you can pre-comp that layer with the opacity change (just one cycle). set the length of the new pre-comp to the length you want to loop. then go back to the original comp, enable time remapping for your pre-comp loop add the expression loopOut(“cycle”,0) and extend the pre-comp’s out to the length you need.

I have only used expressions once before…this would be a good chance to learn (though programming is hard for me). Could you give an example of how to write looping code? I`m going through the help and not finding it, thanks

you can also just add the expression loopOut(“cycle”,0) to your opacity,
this loops out (meaning after the last set keyframe)
and it repeats in “cycle” mode
all keyframes (0, because a non zero number would loop only the last n keys) -
that’s good to know…
i haven’t needed to loop just a single layer (or a single set of key frames), but its’s good to know it can be done so simply.

Ok i`ve stuck with copying and pasting the keyframes (as there are 3 alternating layers that blink) and have dropped that composition into a new one. How can I just loop the new one?

if your blinking comp is the length of the loop that you want (ie. the you want to repeat every 2 sec, so that comp is 2 sec.), all you need to do is enable time remapping (select your blinking comp, then, layer menu>time>enable time remapping). option-click (mac) the stop watch icon and typethe expression: loopOut(“cycle”, 0)
you then need to set you out point for your blinking comp to the duration that you need.
