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.
6.1.2 Creating a New File
Hold OPTION and press SAVE, the LCD will show you the automatically assigned name, press
ENTER to create the file or ESCAPE to abort.
6.1.3 Loading an Existing File
Hold OPTION and press RECALL. Turn the JOG WHEEL to browse through existing files, press
ENTER to load the selected file or ESCAPE to abort.
6.1.4 Erasing a File
Hold OPTION and press CLEAR. Turn the JOG WHEEL to browse through existing files, press
ENTER to erase the selected file or ESCAPE to abort.
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.
