Desktop Video AGOCG Report
The software is split into five small programs: two main applications and three utilities for editing and viewing images. The first of the main applications is VidCap, which handles the job of getting pictures and audio from a suitable source into the machine and onto the hard disk.
The second, VideoEdit, is the most important since it lets the user edit, compress and store sequences for replay. Compression is crucial to digital video and is handled here by plug-in, specially written routines.
When Video for Windows stores data it uses a method known as Audio Video Interleave (AVI), which lays down video with corresponding audio information in an interleaved format. This makes for quick loading, as playback applications need only access a few frames of video and a portion of audio at a time, thus eliminating the need for complex synchronisation routines.
The standard method for playing back Video for Windows files is through the Windows Media Player, which boasts Microsoft's standard 3D tool-bar interface. The other small utilities supplied are WaveEdit, BitEdit and PalEdit, for editing sound, still images and colour palettes respectively. All are basic in comparison to the two main programs, but equally useful for developing video clips.
