The technology of 3D animation and chroma-key

Compositing refers to the process of combining two different clips. Almost all the special effects are strong in good compositing skills. E 'has traditionally been used to describe the mixing of digital movies and real together. There are a variety of composting software that allows you to chroma-key live-action alpha-site channels or digital files in live recordings.

Chroma-Key is the technology, creating a live actors filmed against a green screen or blueand then the blue screen or green with any background of the translator must be replaced fall. There are a couple of blue and green screens on the market, but you can make your own low-budget version of hanging a blue or green sheet and film shoots that before building.

Another solution is cheap, buy linoleum, which can be hung from the ceiling fell to the ground, and extends along the ground. This allows a smooth transition from the rear wall to the ground, and afterPainting with a chroma key blue or green, it works well as a small blue screen. Do not forget the blue screen to clean the floor, as do all the dusty tracks to be very difficult, chroma keying.

Another form of digital compositing is to place people in a shooting in real time. To do animation clips are rendered with an alpha channel. Alpha channels are in black and white channels which parts of an image can be seen and which are deleted to set out. Alpha channels canbuilt-in clip, or made as a separate clip. The key is to make sure that your 3D application knows that you want to create an alpha channel, like trying to delete a clip from a black background with no alpha channel is almost impossible.

There are so many packages of software packages such as 3D compositing. The selection is varied and will increase annually. Adobe After Effects is probably the most popular consumer-level composition of the packages. But AdobePremiere and Apple Final Cut Pro is also a good choice for the composition. Owning one of these software packages is a good idea, even if you do not plan to use real footage with digital files.

Compositing can composite multiple digital files are shared. Several 3D packages have different features than others. Often projects are best 3D packages created in a variety of, and then summarize the results of the composition of animation.
