SOUNDBOOTH CS3 66 User Guide Windows Media Video (.wmv) The Windows version of Soundbooth supports Windows Media Video, Microsoft's format for compressed, streaming video. Typically, WMV files are viewed in Windows Media Player, but other applications and plug-ins also support this format. Options for audio, AVI, and MOV formats mp3 options When you save in .mp3 format, Soundbooth provides the following options: Bitrate Determines the rate in kilobits per second. Higher rates increase file size and audio quality; lower rates reduce size and quality. Mode Applies one of two compression and decompression options. The Best Quality option provides more high-frequency detail and does a very good job at lower bit rates, without introducing unwanted artifacts. The Fastest option encodes audio very quickly but produces lower quality. Mono or Stereo Encodes audio either in mono, which reduces file size, or stereo, which increases file size but retains spatial information. AIF, AVI, MOV, and WAV options When you save in AIF, AVI, QuickTime (MOV), or WAV format, the Save As Options dialog box appears. This dialog box provides a compact group of settings that you can quickly optimize. General options The following options are available in the General section of the Save As dialog box: File Type Indicates the file format. Range Specifies whether to save the entire file or the currently selected range. Export Video Includes video in the saved file. Export Audio Includes audio in the saved file. Add To Files Panel Adds the saved file to the Files panel. Audio options The following options are available in the Audio section of the Save As dialog box: Compressor Specifies the audio codec, if any. The codecs available depend on the platform and file format. In Mac OS, only the Uncompressed option is available. In Windows, DV AVI supports only the Uncompressed option, but WAV and standard AVI provide these additional options: • IMA ADPCM Compresses 16-bit audio to 4-bit. This compression scheme can be a good alternative to MPEG-1; it provides fairly fast decoding and degrades audio quality only slightly. • Microsoft ADPCM Compresses 16-bit audio to 4-bit using a slower method than IMA ADPCM, but quality can be superior, depending upon audio content. • CCITT A-Law Compresses 16-bit audio to 8-bit, but produces dynamic range equivalent to13 bits (78 dB). This compression scheme is the standard for European telephone systems.
