Does After effects go Pixel Deep??
I am trying to calculate the Pixel rate that the Layer is moving at, IE how far a pixel moves perframe, we are trying to get it at three and have done the calculations, to do so. However I am wondering is there a way in after effects to Adjust or control, or check in upon the rate at which the pixels are traveling… for each layer .. this is very important do to the fact we are filming out tese comps, once exported as Targa…?? Thank you for your speedy reply?

You could display the speed of a layer by adding an expression like this to a text layer’s Source Text property:
thisComp.layer(“your layer”).position.speed
This gives you pixels per second. If you want pixels per frame, this should work:
thisComp.layer(“your layer”).position.speed*thisComp.frameDuration

Thank you. . . Just as a side bar, once the expression is entered will the pixel rate be displayed in the value menue under position or if not where should it be display?

The text layer that you apply the expression to will display the speed in the comp window.
You can also look at it by twirling open the Position property and looking at the speed value (you don’t need the expression to do that).
