53.1 Overview

Hollywood's video library provides functions for loading and playing video objects. Video objects are Hollywood objects which contain a video stream that may be bundled with an audio stream. When playing a video object, Hollywood will make sure that video and audio streams are perfectly synchronized with each other.

You can open a video file from disk using the @VIDEO preprocessor command or the OpenVideo() command. To play a video, use the PlayVideo() command.

Hollywood's video library supports two different renderers:

  1. Inbuilt video renderer: This is a platform-independent video renderer supported on all platforms. It is the most flexible video renderer and supports advanced features like video layers and plugins. The only video format natively supported by the inbuilt video renderer is the CDXL video format developed by Commodore in the earlier 90s. CDXL isn't very useful for today's video requirements, but the big advantage of the inbuilt video renderer is that it can load videos via Hollywood plugins. Installing video plugins can greatly enhance the functionality of the inbuilt video renderer.

  2. Native video renderer: This is only supported on Windows, macOS, and iOS. This renderer loads and plays videos through the operating system's video interface. On Windows video playback is done via DirectShow whereas macOS and iOS use AV Foundation or QuickTime (on older systems). This renderer is not as flexible as the inbuilt video renderer. It doesn't support video layers and it also doesn't support video format loaders made available by Hollywood plugins.

By default, Hollywood will first ask the inbuilt video renderer to open the video file. You can change this behaviour by using the Loader tag in your call to @VIDEO or OpenVideo(). See VIDEO for details.
