Check out the free training on the new Apple Final Cut Studio suite released July 2009. Final Cut Studio Overview includes three free hours of tutorials on Final Cut Pro 7, Motion 4, Color 1.5, Soundtrack Pro 3, DVD Studio Pro 4, Compressor 3.5, and Final Cut Server 1.5.
Chroma key, also called bluescreen or greenscreen, is the magical process that inserts an image seamlessly onto an entirely different background. Getting the edges of the subject perfect means the difference between a convincing key and obvious chicanery. In Final Cut Studio 2: Chroma Keying, Larry Jordan focuses exclusively on this effect, so a general knowledge of Final Cut Pro and Motion is recommended. He demonstrates the strengths and weaknesses of five different keying tools: Final Cut Pro's native keyer, Motion's Primatte RT, Oak Street Software's vKey2, dvGarage's dvMatte Blast and dvMatte Pro, and Red Giant Software's Primatte Keyer Pro 4.0. Each excels in different areas, so Larry explains typical issues and workarounds, and when to consider using a different application. Example files accompany the course.
