SOLVED PlanarTransform issue...

PostWed Feb 06, 2019 12:21 am

Hello everybody... For my first post I need help... I know it's not really original!
I have some issues with the PlanarTransform! I followed Casey Faris tutorial about the PlanarTracker but instead of a text I put a texture with an alpha layer.
The texture has a resolution of 1024X591 (float32) and the main footage has a resolution of 4096x2304. I applied the PlanarTransform from the PlanarTracker I used to track the object but the texture goes everywhere without following nothing from the tracker...
I don't understand why when I apply a transform node to a still or a texture (which is a still basically), it transforms it at media out...
What I did wrong?

If you have an idea...

This is because you're mix/matching different resolutions.
Transforms in Fusion are relative, so that they're resolution independent.

That does mean that in this case you have to make sure that the resolution of your texture needs to be the same as the resolution of your source image. Because if what you're tracking moves from the left side of the screen to center at 3840 res it means it moves 1920 pixels. But if your texture moves from left to center it moves only 512 pixels.

So a planar transform isn't the best solution in this case. Either you crop your texture larger (to 4K res) or you can use the corner positioner inside the planar tracker to position your texture and you're good to go.
I'd opt for the latter personally.

SOLVED: PlanarTransform issue...

Thank you Sander de Regt,

It worked after all... I didn't have to create a a Planar Transform to link to the texture.
I just had to connect the background node directly to the PlanarTracker and change the operation as Corner Pin (as you said) and everything work fine... Just have to swap the input sometimes to see the background and foreground in the good sense.
It worked!

Thank you.
