I was just thinking about a shot that I might be using in a movie.

As we all know, if you have the right pictures, photoshopping one persons head onto another persons body isn't hard at all.

Well i was thinking of this: Lets say you had a character who was obese. But then something happens ( he starves, works out, wtvr) and he gets really skinny. maybe some kind of comedy movie.

So the original actor would be skinny. Then you would have him and someone of the same hight and color (but very fat) doing the same thing in front of a greenscreen. Would it be practical to try and roto the skinny persons head onto the fat person and have it look real? then it would be easy to morph that movie clip to a clip of the skinny person to show the rapid passage of time as the person gets skinny.

I dunno, i was just messing around with Vlab and noticed that it had such a huge range of grading filters it reminded me of photoshop.

Is this practical?

As an effect, placing one individual’s head on to another’s body is very possible in VisionLab Studio. However, the quality of the end result will greatly depend on how the entire effect is executed. It would have to be planned out methodically, with every aspect conscientiously anticipated. The complexity of the shots (movement, angles, etc...) will have a large impact on the effect, and your workload.

Again, planned well, this could work, but in any event, this type of effect may be a large undertaking, and if it is at all possible, you should consider something more practical. Perhaps a "fat" suit is an option? Give the appearance of the character being over weight, and maybe even some prosthetics on the face to make it more convincing. Although I do not have any on hand, there are some nice sites that offer convincing make up for just these things, and even take on custom orders.

Edit: Ah, very good BackOfTheHearse, that is a good example of one of the sites I had in mind. Although I have never used their service, their products appear to be of a good quality at first glance.

Something to look into.
Wizard.

As Wizard said, there are sites that sell prosthetics for this purpose.

In fact, here is one: http://www.makeupmania.com/Details/IA-0024-02-001.cfm

Backofthehearse, that looks cool, but do you have to then apply makeup to that prosthetic? it looks a bit to complex and expencive for what i had in mind.

The prosthetic is essentially like a "blank slate"...

You glue it down to the skin, seal the edges with latex stipple, and then apply a base coat of makeup. That base coat is similar to the actor's own skin tone. After that, highlights and shadows are added to show the contours of the skin. Finally, it is all powedered to "set" the makeup and keep it from smudging.

It is a long process, but believe me when I tell you that it is worth it. Want proof?

Here is me:




Here is an actual photo of a product I purchased:





And here is an actual photo of me after undergoing the process of applying the prosthetic:

Rotoing a head and ending up with a good looking product would be SO tedious. Prosthetics does seem like the best way to easily pull off that effect.
