Superimpose Human Face on Fish/Tree
Hi,
I have a chidlren dance piece with MultiMedia coming up.
In the story, in the film, there’s a fish swimming, who is the Narrator of the story. My original plan is to film a real fish (a not too active one, more the slow type;-) and to film the actor’s face on a GreenScreen.
I work with AfterEffects, but I have to mnetion, that I am not very good and experienced with 3D.
Will it be possible to Track and Superimpose the image of the head on the Fish – that it will look o.k.? How can i make the transition of the face into the animal more smooth and not too obvious?Thanx for the help!!!!!!
Greetz,

How did Monty Python do it in this case? That is kind of what I had in my head.
Thanx!

Depending on the believability you’re after, this may be near impossible without a 3D software and 3D tracking.
I suggest you try a simple comp with a still image of a fish and a human face. That will give you an indication of the look you’re after. Then add the difficulty of havinf to ensure that the face is moving (both in position and scale as well as the surface of the fish) and you’ll get a pretty good idea that AE may not be ideal for such an effect.
BTW, the fishes in the video are CG.

Thanx for the advice. I am not after a complete Hollywoodic reality look.
It can be in an abstracted way – it should look artistic and interesting, not neceassarily hyperrealistic.
The problem is, that I kno FCP, Motion and After Effects, so it had to be made in one of those programms.Greetz,

LIke I said, give it a try on a single frame for you to have a better idea of what the composite will look like.
For an animated look, you’ll require at least the following effects –
1) diaplacement mapping to mimic the animated surface of the fish
2) motion tracking to ensure that the face follows the face
3) Blending Mode to make the composite more believable by blending the face onto the fish
4) chroma shoot and keying of the faceThose are what I can think of, off the top of my head. And each one of those effects has their own issues to contain.

HI Roland,
thanx for the advice – that’s kind of what I had in mind and I am familiar with all those technics.
The only thing that doesn’t tell me anything is “Diaplacement Mapping” – would you mind to evaluate on that subject?
Thanx a lot.Greetz,

Have you considered possibly a fish puppet? That would do nicely for a story book type effect. The puppet could serve as the totally controllable body of the fish, then you could still put the actor’s face on in post.
If you record the actor first, with maybe a green head sock on a green bg (or blue or whatever), then you could run the puppet to sync up with the actor. Then key out the fish and composite. If you painted some scales similar to the fish’s on the actor that might make the finished image more seamless as well. Don’t forget to get some side shots of the actor if you plan to have the fish swim around at all.
Plus, with this way you won’t need a displacement map since you can just make the fish swim around at will. You might even be able to use some stock animation for the water. Something with exaggerated bubbles and seaweed and such.

Alright, just noticed the date on your posts. I found this looking for something else and it looked interesting.
Hope this year old project turned out ok.
