Make your video backgrounds disappear
Many people want to create video titles with transparent backgrounds so they can then import them into their non-linear editing software (NLE) and overlay the titles onto existing video. You can do this using Wild FX Pro. This tutorial contains information on how to do this with two popular nonlinear editors: Adobe Premiere and Sony Vegas.
How to use Wild FX Pro video titles with an alpha channel in Adobe Premiere and Sony Vegas
ABOUT THE ALPHA CHANNEL
One of the most popular methods for creating transparent backgrounds in video is to use an alpha channel.
Images represented on video are composed of three grayscale images called channels – one red, one green, one blue - or RGB images. An alpha channel is a fourth channel in
an RGB image that defines what parts of the image are transparent or semi-transparent.
An alpha channel can be either straight or premultiplied, depending on the program that created the image. Wild FX Pro uses the straight alpha channel. When an image contains a straight alpha channel, the transparency information is stored only in the alpha channel.
