Set the file type :
A choice must be made for the eventual file type of choice should you want to connect the DN-600 in the
HDD mode to your computer and drag and drop your video content as files. The choices for DV are Microsoft
.avi type II, Canopus .avi type II, both commonly used in
PCs, .mov, the QuickTime format used in Macs and
.mxf a new universal file format supported by a growing number of applications, Avid being the most well
known. In HDV mode, the file type is fixed at .m2t.
Note : The file format started with one bin will apply to all subsequent recordings in that bin and can only be
changed after the bin is erased or emptied.
Synchronize to tape motion
The recording of the DN-600 can be synchronized to the camera’s record button by turning Sync To Tape ON
(
ST1 ). Whenever the tape in the camera is rolling, so will the time code. DN-600 recognizes the motion and
will record along with the tape. When the motion stops, DN-600 will pause the recording. To record
continuously without regard for tape motion, switch Sync To Tape off (
ST0 ). Some cameras control the DN-
600 directly through the 1394 interface and in these cases, use ST0 and let the camera do the work.
Select the sampling rate of the audio in the DV mode
This option will set the audio sampling rate to 32KHz or 48KHz when the video source is analog. When the
video source is digital this setting will be used as the starting guess frequency of the audio portion of the
digital stream. If the guess is incorrect then the first two frames of data will be discarded as the DN-600
resets itself.
Note: Only one type of audio sampling rate can be used within a bin.
Set the record date (optional)
The date attribute of the created file is set to this value when the source is analog. Each file representing a
clip gets it own date. If the source is digital then the record date from the digital stream is used. If that date
is not valid then the current record date set by this option is used.
Recording
Starting
Select one of 99 Bins by pressing the PREVIOUS or NEXT keys in the Idle menu.
Two common ways of starting to record are 1) by entering the record mode manually by holding the REC
button down while pressing the PLAY button. Or 2) the camera or device connected to the 1394 port sends a
record command. A third way is to issue a record command from the remote serial interface. See the
command protocol in Appendix B.
Pausing
The DN-600 will pause recording if time code is not moving and ST1 is set, otherwise it will record. When the
video source is digital the time code is embedded in the stream and it is always the time code recorded.
When the video source is analog, time code is the SMPTE longitudinal time code at the breakout cable. To
cause the recording to pause, that time code must be valid and not moving. If SMPTE time code is not
present then a time code is substituted starting at 00:00:00:00 for each bin and incrementing from there in a
dropped-frame manner (NTSC only). In this case, ST1 has no meaning. It is also possible to pause a
recording by pressing the PLAY key, in this mode, recording is resumed by pressing the PLAY key once
more and a new clip is created.
Warning: If power is interrupted while the recording is paused, all clip numbers added during the
current record session will be lost. No content however will be lost. Future firmware upgrades may
fix this behavior.
Note: If power is interrupted while recording, up to two seconds of the last video may be lost.
Recording
When recording the right soft key is called MARK. Pressing this key while recording will start a new clip with
no frames lost. Each time a recording is started a new clip is created. Up to 97 clips can be numbered in
each bin.
Note:
Recording is done in a bin. A clip is automatically started at the beginning of the bin if the bin is empty
or appended to the last clip in the bin. A clip is never inserted between other clips in a bin.
Note: The minimum length of a clip is 2 seconds.
