About continuous record mode
to create subclips. The media referenced by the subclips that you create is saved
outside the continuous record program and does not subtract from the continuous
record length. The subclips can be inserted in a Playlist application as play events.
NOTE: A program, such as a playlist, cannot be saved in AVI format.
Continuous mode operational considerations
NOTE: For continuous record specifications, see “Operational Specifications” on
page 203 .
Consider the following when planning for Continuous Record operation:
• Maximum continuous record length– Maximum record length is limited by the
amount of storage space and the compression settings used. If the fixed length you
enter exceeds the available disk space, the fixed length is automatically adjusted to
equal the available space.
• Modifying the continuous record name or length– You can modify the
continuous record name or length during record. If you reduce record length, the
oldest media outside the new record length is erased.
• Stopping continuous record– If the recording is stopped before the fixed length
is reached, the resulting program duration is the time elapsed since the recording
started. Like normal record mode, you cannot stop then start a continuous
recording. Once record is stopped, you must eject the program and create a new
continuous record.
• Transferring the continuous record program– The continuous record program
cannot be transferred to a file or networked device until record is stopped.
• Continuous record storage space is not reserved– Continuous record is allowed
to start as long as the record length you enter is less than the available storage;
however, the storage space is not reserved. For example, you could have enough
storage space to start the continuous record, but you are still allowed to transfer
media or otherwise fill disk space. Warning messages are displayed in the
AppCenter StatusBar when available storage reaches 10% total disk space. All
recording is halted when media storage reaches its full threshold.
• Pausing the continuous record program in Recorder/Player application– You
cannot pause the continuous record program in Recorder/Player application
indefinitely. Eventually, the record length is reached and the video at the current
position is erased. As this happens, the current position is advanced in 3 minute
increments as the oldest unused media is erased.
• Changing thumbnail image– Thumbnail images displayed in the Clips pane are
generated using the 16th frame of video. The thumbnail image for a continuous
record program appears as normal until the fixed length is reached. Then, the
thumbnail will update every 3 minutes as media is erased beginning with the oldest
unused media. As the media used to generate thumbnails is erased, new thumbnails
are generated.
• Erasing oldest media is suspended when creating a subclip– When creating
subclips in Player application, erasing oldest media is suspended when the first
mark is entered (mark-in or mark-out). This means that the continuous record
program length could grow larger than the length specified. Erasing media is
