indeed, I always forget that bit until I need it

Frank,
...In your Transform node's translate x expression, you may want to
also add a tweak for the pixel aspect:
translateRel*( width*pixel_aspect)
I've been working on a resolution-independent Slate tool lately and
found I needed to take that into consideration for any anamorphic
standards, such as Cinemascope, PAL and NTSC, just to name a few...

Hi Frank,
this sounds interesting...
would you be able to send me a small setup? I dont think I'm quite

for what I need.
Cheers,

use user knobs that drive the position (and centre position) in
normalised values, i.e 1 = right side of image, 0 is left side etc.
use expressions in the respective knobs that take those user
knob values and multiply them by the incoming width or height
scale and rotate are resolution independent anyway.

Hi there,
This may seem like...well..an odd question.
Ive been asked to setup a multi resolution comp/group/gizmo.
Where the user would have the choice of switching between Low /
Hi Resolution source files.
I know there is the "Proxy" system built into Nuke, but I think
that works on a global level. They want the artists to be able
to view the rest of the comp at an independent
resolution.....does this make sense?
So back to my question....
When setting up the multi resolutions...how can I automate any
transformations to match?
since they're at different resolutions, the transform nodes
have different centers.
Any help or clarity would be greatly appreciated
Steve
