Methods of moving around puppets/stuffed animals

Since my video is going to have puppets or stuffed animals moving as if they are living things, I am going to do some research into the best methods of making this happen naturally, and match them up against each other.

Morph suit method

The first method is through the use of a green/blue morphsuit in an area without that colour. This would consist of moving the puppets from behind, getting them to do lifelike things in my preferred way that fit the narrative or their character. 

I would then chroma key out the green in post production so it was a black figure moving the animals. 

After that, I'd add another layer behind the main layer with the same setting, but with nobody moving inside it, so it filled in the black areas where the morphsuit was originally. 

Risks

This is a quite simple method, but if the chroma key doesn't work perfectly, I can risk it looking amateur.  This can happen if if the green suit ends up being a different colour due to lighting or shadows.

Pros

It is quite an easy method and doesn't take much technical skill in an editing programme.

Masking method

This would consist of a similar process to the morph suit method. I would first get a blank shot of the setting, and then film someone moving the animals around in a desired way. I would then mask out the animals and paste them on top of the blank shot.

Risks

If I cannot mask out the animals professionally I can risk it looking quite low quality.

Pros

If I am good enough at masking to get a good result, I am not relying on the programmes automatic chroma key features and rather my own skill.
