6 Recording and Playback
6.1 Using the V1 Multi-File System
6.1.1 The Default File
The V1 will always contain one default file. The primary purpose of the default file is to allow
operation without using files, thereby maintaining compatibility with existing video tape
recorders.
The default file will not be included in the list of available files maintained by the V1, and will not
be returned when a list of available files (clips) is requested. The default file may be specified
and used for all other purposes. If no other valid file has been specified and loaded, such as on
initialization and errors, the V1 will load the default file.

6.1.5 Files and Time Code
Each file is considered to have available a “pre-striped” time code range with continuous
ascending time code beginning at 00:00:00:00 through the largest valid time code position
specified in OPTION MENU (3) “
New Rec Set
”, the default value is 24 hours. When in A-time
mode, video material may be recorded at any time code position within the file, when in Time-
Code mode video is recorder at the incoming time code position. Time code positions that have
never been recorded over are considered to be black video.
6.1.6 Setting Recording Parameters for each File
Each file can have different recording parameters. The recording parameters that will be saved
when a new file is created are in the OPTION
MENU (3)
New Rec Set
which includes
compression ratio, bit rate, number of audio tracks, duration, NTSC or PAL, 1080i or 720p HD
formats etc. The available settings depend on the V1 model in use and the options installed.
6.1.7 Mixing Recording Parameters
Every file can have its own recording parameters (such as compression ratio), but to create
play-lists that use more than one file, the recording parameters should be the same for all files.
If they are not, the transition between files during playback will no longer be seamless.
