I am new to video production, but I am looking to create a series of Yoga videos for online use. They would be sold online, after production which will include indexing of words used in the tutorial (using voice recognition). I have an instructor interested and I am addressing the issue of Chroma Key.
I want to place the instructor at a scenic location, such as a sunny beach, or on a mountain. Several professional Yoga DVD's are filmed that way, as it adds to the general feel of relaxation.
I understand how the wall can be a blue screen, but what about the floor? I am a little unclear how the floor could also be used to allow the new landscape video to be added.
I talked to a retailer when trying to buy the screens, but he said Chroma Key only worked for walls.
Yoga needs the floor to be filmed as many postures involve the floor, eg sitting on the floor.
Does anyone have any help on using Chroma Key to film Yoga (ie the whole person would need filming) and what equipment is best to buy? I googled the equipment side of this, and I got a huge amount of hardware and software information: too much to understand.
