When using Premiere for Chroma Keying, you need to add keying material and background material respectively in two tracks.
The background material should be below the keying material, because in most cases Keying is to control the material’s transparency to achieve the desired effect, so as to display the background layer at the bottom [5].
Research on the effect of DV video material keying [J].

Fuzzy finite element applications in the waste heat boiler Chao Li1,a, ChangHong Liu1,b, XinChuan Qin1,c,YongTai Li2 1School of Mechanical and Power Engineering, East China University of Science and Technology,Shanghai 200237,China. 2 Hefei General Machinery Research Institute ,Hefei,230031,China acpu533mhz@163.com,bliuchanghong2008@hotmail.com , c qxczm@yahoo.com Keywords: Fuzzy analysis; Finite element; Waste heat boiler.
The uncertainties in the material, loading and structural properties are represented using convex normal fuzzy sets.
If any of the system input variables, namely, material properties, structural properties, geometric properties, boundary conditions and loading is fuzzy, then it has to be fuzzified.
