Set scale in pixels using expressions
You can right click on a scale, hit Edit, and then enter scale in Pixels, inches , % of Comp, of source…. How can set the units using expressions?
They default to percentages of source (I think) which is somewhat limited.

Now position another layer to always be 20% taller than the text layer while text layer always being at the 66 percent of comp height regardless of the font family and size and number of letters, lines… Should I go on? ????I think pixels make things easier

I think the problem is that scale is logarithmic or at the very least exponential. But I can see a use for pixels was well, but then it should be called width and height. Aren’t width and height parameters you can access in the expressions? (I’m not in front of the machine at the moment so I could be thinking of C4d’s scripting language).

You can access them with sourceRectAtTime method. The problem is that accessing is all I managed to do. There is no setSourceRectAtTime for example. I tried setting scale as [“200px”, “100px”], but that returned an error

That’s correct. You’ll have to do the math to convert from your desired pixel size to scale percentage of original. Here’s an expression you can apply to a 2D scale property that lets you input in the scale in pixels directly into the scale property on the timeline without opening the dialog box:
[value[0]/sourceRectAtTime().width*100, value[1]/sourceRectAtTime().height*100]Walter Soyka
