What tutorials? Sorry to be so direct, but this isn't something you will achieve by someone telling you which buttons to push. You need to learn several things here form creating animated strokes to masking out individual regions in the first place to using complex particle plug-ins or simulation tools in a 3D program like the animated movie quite obviously does. This can take you months to learn. Even if you already knew this stuff already, it would still be a lot of work.
I'm just looking for something more simple for example morphing into smoke and then morphing back again to the original form
thank you! I'll check it out

The first step in breaking down a visual effect is to take a look at the shot one frame at a time. Let's start with this frame:
I'm assuming you are doing live action and not animation. What we have here is a background, a character (actor) appearing to materialize from blowing smoke, a foreground element (the chair and the floor.
At a minimum you will need to stack layers like this:
- Foreground plate
- Smoke layer
- Actor layer
- Background plate
By foreground plate I mean that you'll have to separate any foreground elements from the background so that you can put the smoke and the actor behind the foreground. With live action footage this is usually done by rotoscoping.
The smoke layer can be achieved with in a number of ways including particle effects, displacement mapping (which requires another layer) and even practical effects like filming your own smoke or buying stock footage.
The actor layer can either be shot on green screen so you can easily remove the background or can be shot on location and you rotoscope the actor.
The background plate would be the whole original scene but you'll what this to be a "clean plate" so you shoot that without the actor in the scene, then, if you want to shoot your actor on location you shoot it again with the actor in the scene.
Now it's just a matter of lining up things, doing some masking, and creating the transition between the smoke and the actor. There about a million ways to do this shot but all involve at least the four layers (plates) that I described.
thank you so much! you've taught so many valuable things!
