Help looping a Time Remap for a linear value of another property

Hi !

 

The short version:

 

I'm desperately trying to link time remaps and make it so that time remap B loops every X frames of time time remap A.

 

Basically, what I'd like to do is, when TR A plays, say, 15 frames, TR B plays it's full length, then when TR A plays another 15 frames (raching frame 30), TR B loops again. It doesn't have to be a number of frames, percentages will do. Percentages will probably be more helpful.

 

And then, I'd like to be able to apply the expression to a TR C linked to TR B, then TR D linked to TR C, etc

 

Hopefully I've somehow managed to convey my issue. Thanks in advance !


More details:

 

I'm trying to do an animated rotating number counter with a big, big number. It goes from hundreds to million. The rorating numbers are animated in a precomp, so far so good, but I just cannot have a long enough timeline to link loop the animation in the precomps and then link and speed the time remaps in a parent composition.

    The modulus operator is your friend. Could be as simple as

     

    time%framesToTime(15)

      Hey, thank you for your reply.

       

      I've never used this expression, could you give me advice on how to set it up?

      Hold ALT and click on the stopwatch of your B layer's time remap.  Use the pickwhip to select your A layer's time remap property, then add the following code to the end of the expression:

      alayer.time%framesToTime(15)

      The bit before the % should be generated for you by the pickwhip.  

       

      Personally, I'm never 100% confortable with modulus, I like it more spelled out, so linear would also get you there:

      linear(alayer's time,0,100,0,15)

       That takes the A layer's time in seconds, and if it is 0 seconds, set B time's to 0, and if it's 100 seconds, set B to 15 (and map the range of values inbetween accordingly).  It's more long-winded and you have to know the final time for A, but I think it spells it out more when you're learning.
