    • Multi-media project editing methods and systems are described. In one embodiment, a project editing system comprises a multi-media editing application that is configured to enable a user to combine multiple different video clips into a video project. A bitmap processor coupled with the multi-media editing application receives a first bitmap that can be used to render a transition between video clips and automatically processes the first bitmap to provide a different transition between video clips. Processing of the first bitmap can include, without limitation, using the first bitmap to provide an entirely new and different second bitmap, or processing the first bitmap in a manner which renders a transition that is different from the transition defined by the first bitmap. In one embodiment, a user is able to enter one or more parameters, through a user interface (UI), with the parameters then being used to manipulate the first bitmap to provide the different transition. Processing of the first bitmap can include many different operations, among which can be included one or more of: stretching, shrinking, replication, and offsetting. In addition, the first bitmap can be processed to include, in the transition it defines, a border that is not otherwise defined by the first bitmap.
    • 描述了多媒体项目编辑方法和系统。 在一个实施例中,项目编辑系统包括多媒体编辑应用,其被配置为使得用户能够将多个不同的视频片段组合成视频项目。 与多媒体编辑应用程序耦合的位图处理器接收可以用于呈现视频剪辑之间的转换的第一位图,并且自动处理第一位图以在视频剪辑之间提供不同的转换。 第一位图的处理可以包括但不限于使用第一位图提供全新且不同的第二位图,或者以呈现与第一位图所定义的转变不同的转换的方式来处理第一位图。 在一个实施例中,用户能够通过用户界面(UI)输入一个或多个参数,随后参数被用于操纵第一位图以提供不同的转换。 第一位图的处理可以包括许多不同的操作,其中可以包括以下一个或多个:拉伸,收缩,复制和抵消。 此外,第一位图可以被处理以在其定义的转换中包括另外由第一位图定义的边界。
