Why is it still lacking to Fusion? :(

I agree with theo. This demonstration sucks.

I have done way more radical beautification on female talents with Fusion in an invisible way years ago.

If it wasn't for the promise i gave to never show the original footage I would post here before/afters. Fusion eats this for breakfast.

This seemed pretty impressive, automatic tracking based on oflow......self contained.

I've done lots of paint corrections, but it has always been a combo of fusion trackers, mocha ect

I dont think the final image was the point...it was the simplicity of the integration, the author bills it as 'a quick and dirty solution if you have 100 shots to do'

It might be simple but you also need color correctors and grid warping in the mix for really cool results. The tool demonstrated might be simple but by only "sticking" bitmap patches like that will not take you far.

its basically an auto tracker.......just a part of the workflow, the rest is up to the user

Because Fusion lacks a planar tracker.

I think that gizmo just sticks patches to the face but since Nuke's rotopaint tool allows you to add a transformation matrix to any stroke or layer you could deform the actual paint or clone strokes on the face.

on his blog you can read what it does, no planar tracking involved.
he does a 3d track of the scene, uses the pointcloud (as rendered/projected to viewplane points) to drive a optical flow warp which distorts a UV map (STmap in nuke). with the distorted uvmap he patches the painted stuff in the image

the only part i dont get is how he calculates the the motion and speed vectors for the points

(quiet some lines of code involed as you can see in one of his pictures)

LOL. I'm so used to embedded vimeo clips where the link beneath goes to vimeo that I glossed over it completely.

Hehe, I know what you mean. I was feeling lazy when I posted this... Should have added more info.

If you cam project default screen coordinates onto your patch on the first frame ( or your reference frame) as a texture, you can subtract the distorted output from yet again a default screen coordinates gradient to create motion vectors. All ops in full float of course.

This will create vectors to offset your reference frame to any other frame.

The text seems to indicate it's just a subtraction of UV lookups of adjacent frames.

Edit: seems I was slow on the reply.
