Hello all, I have been asked to come with a solution to a TVC storyboard that involves the following Fx. The spot takes place at a breakfast table surrounded by a family of 4, the father (who is our hero) interacts/converses with his family (wife, girl, boy)…they all have his face (this is a well known person who is also well known for wearing glasses!). I am assuming the director will insist on camera movement. Has anyone tried this sort of thing before ?
We’ve just finished doing a trade-show here in South Africa with the guys from discreet. One of the “canned” demos Grant Kay did using flint was the face replacement effect they used for the Ford Mustang/Steve McQueen commercial.
If you can get your hands on a “tutorial” that explains how they did this, it’ll point you in the right direction.
Cheers
TW.I would explore the good old way to do that easily :
Motion Control and multiple passes.
If you can afford a small compositing station on set it’s even easier.
We used to do that using a laptop and combustion, capturing the video-assit with a little canopus box on Avid Express on the same laptop and quick compositing to check.
And as you get the motion control data, you can re-do the intersections (necks, shoulders) in 3D if needed.
Kuruizuki is right. Why would you replace faces, when you can shoot them? Just dress the actor like that, and maybe you can also do 2D warps, to give the actor a childish look, with warped body proportions.
True, but what happens if the “famous face” they need for this commercial is either no longer with us, or unavailable for the shoot ? (Like Saddam Hussian 🙂 ) although I don’t think I’ve ever seen him in glasses !

If they don’t have the “actor” alive or on set, then it’s going to be more complicated, it will involve a very good documentalist to find archive footage to match the shooted shots. I would even do it backward, first do a basic previz with archive footage and then shoot following what you have found…
Well, I can’t do a breakdown/solution without all the infos and storyboards, so I can only give advices ^^;.
Take a look at PFTrack V3 from The Pixel Farm. It has tools to track 3D geometry into plates. You can then simply apply a texture to the geometry and comp in 3D in flame, or render of 2D and comp in shake. It’s very easy to use and was used extensively by Stan Winston for the Fantastic 4.

Hi.
I just achieved ad face replacement shot on a short film here, using a good 3d tracking soft (Boujou, but any other can do), and a decent 3d software.
Thought this solution involves some issues (correct on-set light mesurements, light probes, sufficient tracks, ans a qualified 3d artist), the full shot was achieved in a very short time, therefore without having it cost to much…
Yet if you have a MoCo rig, then I guess you’re all set…
Keep us informed !Hope it helps,
L.T.
France.
