Name of property Anamorphic Aud Format Aud Rate Audio Capture Comment A-B Composite Compressor Creator Data Rate Description XI Description A checkmark in this property indicates that the media file's pixel data was intended to be displayed anamorphically (stretched wide). You can set this property to force a clip with a 4:3 aspect ratio to be widescreen 16:9. For clips, this property is originally based on the capture preset used; for sequences, it's based on the sequence settings. You can change this property at any time. The bit depth of each audio sample (typically 16- or 24-bit integer). The audio sample rate of a sequence or a clip's media file. Indicates the number of mono and stereo audio clip items for a clip and its corresponding media file. Displays the capture state of a clip in the Batch Capture queue: Not Yet, OK (captured already), Queued, or Aborted. Comment information that is not shared across each master and affiliate clip (as opposed to Master Comments 1-4, which are stored in the master clip and shared with all affiliates). Shows the composite mode of a clip, such as Normal, Add, or Travel Matte. This controls how the pixel values in a clip combine with the pixel values in clips in underlying video layers, or how the clip visually interacts with the clip on the track immediately below it. For more information on composite modes, see "Compositing and Layering" on page 775 Displays the codec used to compress a clip's media file. For clips, this property is based on the content stored in the clip's media file; for sequences, it's based on the codec specified in the sequence's compressor setting. Different codecs have different ways of compressing video and audio clips to reduce storage requirements. When a clip is edited into a sequence, the clip's media file must use the same codec as the sequence, otherwise Final Cut Express HD must convert from the media file codec to the sequence codec, which usually is so processor intensive that it requires rendering. Shows the name of the application that created the clip's media file. Shows how much data a clip's media file requires per second of playback. This value is displayed in megabytes per second. The data rate of a media file is determined by its video frame rate, dimensions, compressor, color sampling method, and audio sample rate and bit depth. Generally, the higher the data rate, the higher the quality of the media file. If the data rate of a clip's media file exceeds the capabilities of your hard disk, Final Cut Express HD warns you if frames are being dropped during playback. Displays descriptive text about a clip (from the Description field in the Logging tab of the Capture window). This is typically entered when logging, but you can also add to it or change it in the Browser or Item Properties window. Chapter 63 Elements of a Final Cut Express HD Project 917
