Hi,

I'm using the numbers effect to generate an avi for a list of numbers from 1 to 80, problem is i need each number to display for 9 frames? Could anyone explain how to do this with an expression and a brief explanation?

I'm using it as a texture in a 3d animation, i did one by hand but now my client wants to change the font!

Thanks in advance.

You can do this with an expression on the Numbers effect's Value property or the Source Text property of a text layer.
time returns the current comp time in seconds, so time divided by the duration of one frame (in seconds) gives you the time in frames:

Code: Select all

time / thisComp.frameDuration;
you want each to last 9 frames so you could divide that by 9:

Code: Select all

(time / thisComp.frameDuration)/9;
but you also want the result of this to be rounded down to the nearest integer (whole number):

Code: Select all

Math.floor((thisComp.frameDuration)/9);
but as this starts from 0, you also need to add 1 to make it start from 1:

Code: Select all

Math.floor((time / thisComp.frameDuration)/9)+1;
