Slider to control time remapping
For the animation of a person’s face, I’ve created a series of mouths in different positions (6 to be exact) and precomped them, with a different mouth on each frame. I wanted to add a slider controller to make switching between them easier.
So, I made a null, named it FaceControl, added a slider to that layer and named it Mouth. Then I added a Time Remap to the mouths layer and added this expression to it:
sliderPos = thisComp.layer(“FaceControl”).effect(“Mouth”)(“Slider”);
[(Math.round(sliderPos))]The problem is if I change the slider to any number bigger than zero, the mouth layer jumps to the last mouth (6).
What am I doing wrong here?

Based on this thread I was able to make it work. I needed to make my comp 25fps and add a *.04 operator to the last line.
This now works:
sliderPos = thisComp.layer(“FaceControl”).effect(“Mouth”)(“Slider”);
[(Math.round(sliderPos)) * .04] -
It looks like your original expression was set up assuming that each mouth position had a duration of 1 second. I’m assuming you’re got it set up with a different mouth position on each frame. If so, you just need to change the original expression to this and it should work with any comp frame rate:
sliderPos = thisComp.layer(“FaceControl”).effect(“Mouth”)(“Slider”);

Even better! Now I don’t have to go through and change all my comps to 25fps. Thanks Dan!
