Recorded MXF files are written onto the LTO tapes as they are being recorded,
but writing may
take some more time
even after recording is completed. Proxy
files are not written as they are being recorded but are written after MXF files have
been written. The next recording cannot be started unless the writing is
completed.
Recording across multiple LTO tapes are not possible.
Recording stops when there is no more free space on an LTO tape.
When recording in
REM.1
mode, be sure to check that there is
enough time for
pre-roll
before the IN point. Otherwise, the IN point may be set incorrectly or
recording may not start due to the pre-roll failure. Refer to "VTR Control Settings"
in the "4-10-3. Interface and System Setting Menu Screen" for details on the
pre-roll time setting.
Available VTR commands (Sony 9-pin protocol, RS-422 connection) are shown in
the table below.

If "Timecode in file" is set to
Ancillary TC or LTC
and the ancillary time code
disappears during recording, the recording process may
stop
in some cases.
The Monitoring screen, built-in speaker and headphone out are provided only for
monitoring use and to ensure easy operation. To precisely check the audio and
video quality, use appropriate devices by connecting them to the rear of the unit.
In recording mode, signal timing differs between the built-in speaker or headphone
and SDI audio.
On rare occasions, the sound heard through headphones or speakers may skip.
This does not affect the SDI or AES sound.
Do not
make a loop connection such as by connecting SDI IN and SDI OUT
directly at startup, which may result in malfunction or failures and inputs may not be
accepted. The device can be recovered by changing the encode profile but may
malfunction again when switching between REC and PLAY.
When recording in
REM.1
mode, the recording may stop if time code on the video
source is
discontinuous
, or be interrupted if the VTR returns
Lost Lock
messages for more than two frames. This is because, in these cases, Master
mode cannot correctly specify the IN and OUT points for recording. To properly
record the video, change the mode to
Manual
.
Do not
change write protect On/Off switches while LTO tapes are inserted in the
LTR recorder. Doing so may cause significant errors in some cases, such as
recording failures or missing recorded files.
Be sure to eject LTO tapes from the LTR recorder before changing the write protect
switch status.
