Layer shift when element moves too far off canvas

Hi there. Anyone experienced this too?
3 PSD elements on a layer. Animate the one object to scale up and Left out of the view of the canvas. Once I drag it beyond a certain point, the whole layer moves (without any keyframes anywhere) as if it's compensating to keep all the element within a specific range of the canvas. Thus, the other two PSDs moves to the right equivalent to how much I move the scaled object further towards the left.

Switching project settings to a larger canvas like 1080i allows me to move it beyond the restriction of the SD project, but if I keep goin the same thing happens once I drag it out far enough beyond the canvas. Solution was to put the objects on diferent layers. But was just wondering if my suspicion is true that there remains an invisible barrier around the canvass that does not know how to let go of pixels that are of no use to track any more?

Hey Francois,

This shift is because you are exceeding the max texture size of your graphics card. Motion uses the GPU for all image processing, so if any image or result (like your comp) gets too big, the card has to crop and recenter. This is done by the hardware, not Motion. ATI cards are currently limited to 2048x2048 and Nvidia cards can handle 4096x4096.

There's a much better explanation here: http://www.motionsmarts.com/tutorials/nutsandbolts/sizematters.html

Good luck!
