Example: You have copied a region from clip 001 and pasted to clip
002. Now you DELETE clip 001. The copied frames are still reserved
by clip 002 and will not be overwritten by new recordings.
MENU 017 MAXIMUM RECORDING TIME
bonsaiDRIVE recordings are organised in several CLIPS.
The maximum recording time can be set to SINGLE or MULTIPLE
CLIPS with a duration of 240, 120, 60 or 30 minutes.
When set to SINGLE CLIP 60 MINUTES for example the machine
stops automatically a recording after 1 hour. Of course you can also
stop a recording at any time manually by pressing the stop key.
When set to MULTIPLE AT 30 MINUTES the machine stops
recording the first clip after 30 minutes and starts to record a
following clip with increased clip number automatically.
MENU 018 VIDEO RECORD FORMAT
From firmware version 00.40 there are two different video codecs
implemented:
(1) bonsaidrive LOSSLESS
This is our proprietary Huffman codec used in all earlier firmware
versions.
This codec consumes about 40-60 Gbyte/ hour and does not modify
the video data. Data reduction is achieved by Huffman coding and
the coded and decoded data is identical.
(2) bonsaidrive LOW RES
For some applications the high uncompressed video quality is not
required and instead less disk space consumption desired. The new
bonsaidrive LOW RES codec consumes about 15-25 Gbyte/ hour
and allows you to record up to 40 hour on a single 750 Gbyte disk.
Only new clip recordings (RECORD MODE = CRASH) will take over
the video record format selected in this menu. ASSEMBLE or

INSERT recordings are automatically executed in the format of the
existing clip.
In MENU 001 "SELECT CLIP" the format of each recording is
displayed: LOSSLESS or LOW RES together with the video standard
PAL / NTSC DROP or NTSC NON DROP.
MENU 019 RECORD MODE
In this menu the record mode can be selected with the [+] and [–]
keys. From firmware BF 00.30 the following modes are available:
WRITE PROTECTED DISK
CRASH
ASSEMBLE
INSERT PREVIEW
INSERT RECORD
WRITE PROTECTED DISK means that all harddrive write
functions are disabled, including SAVE CLIP INFO TO DISK,
DELETE CLIP and FORMAT DISK.
This allows additional protection against accidental recording over or
deleting of files in certain applications.
The selection of CRASH puts the video channel and all 10 audio
channels in a record ready mode. A CRASH recording automatically
assigns the next free clip number from current clip number position.
CRASH recordings are stopped using the stop [
■ ] key.
Selecting ASSEMBLE record mode sets the TRACK ARMING in
MENU 020 automatically to 8TRK + 2TRK + VIDEO. To enter an
ASSEMBLE recording the unit must be in the locked play forward
condition. Therefore press the play key [
► ] to start a locked playback
forward. After one or two seconds when the units is locked hold the
[RECORD] key down and press the play key [
► ] to start an
assemble recording. Press the stop [ ■ ] key to finish and exit the
assemble editing.
ASSEMBLE recordings perform a so called "clean in", which means
a seamless picture editing at the IN point together with a smooth
