I can’t see a way to edit my post, so just a little addition: I missed the fact that you already have an expression in the wipe value. But I guess this can somehow be combined by replacing all my value statements in the expression with some variable that’s referring to what your already existing expression spits out.

I have come up with this expression to do it (just paste it in the linear wipe percentage). For now this only works for a left to right wipe (-90° angle), so some of the calculations need to be flipped to work in the other direction. The buffer variable is just used to wipe away an extra pixel on both ends, because sometimes a column of subpixels stays visible on either side of the text layer.

I guess it would be very hard to adapt this to arbitrary wipe angles, but changing sourceRectAtTime().left to sourceRectAtTime().top and sourceRectAtTime().width to sourceRectAtTime().height should at least allow for vertical wipes.

buffer = 1;
x_start = thisLayer.position[0] + sourceRectAtTime().left - buffer;
x_end = thisLayer.position[0] + sourceRectAtTime().left + sourceRectAtTime().width + buffer;
c_w = thisComp.width;

100-linear(value, 0, 100, ((x_start/c_w))*100, ((x_end/c_w))*100)

That’s exactly what I had in mind, thanks so much!

Bringing this oooold thread back up, I was wondering how Dan’s expression up there needs to be changed to not play and stop at each marker, but always stop at each marker and only play for the duration of a marker (you know, when you split and drag it apart with ALT and click).

So basically the time between markers is the hold time, and the duration of each marker is play time. That way it’s a bit more practical for time-remapping purposes, because moving a marker will always move its duration along with it.
