XI
Anamorphic 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.
Aud Format The bit depth of each audio sample (typically 16- or 24-bit integer).
Aud Rate The audio sample rate of a sequence or a clip’s media file.
Audio Indicates the number of mono and stereo audio clip items for a clip
and its corresponding media file.
Capture Displays the capture state of a clip in the Batch Capture
queue: Not Yet, OK (captured already), Queued, or Aborted.
Comment A-B 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).
Composite 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
Compressor 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.
Creator Shows the name of the application that created the clip’s media file.
Data Rate 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.
Description 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.
