Grass Valley iTX System v.2.6 - Manual (Page 271)

Working with iTX services on an Encode Server machine
Set the in-point timecode flag for recordings
For the in-point of the recorded media, the iTX Encoder may take the timecode from the digital
video source or it may set a value of zero (00:00:00:00). You select the option you want it to
use.
1.
Do one of the following.
• If you want the in-point timecode of all recordings to be zero, select Disable In-Point
from TC.
• If you want the in-point timecode to be taken from the digital video source, ensure
Disable In-Point from TC is not selected.
2. If you want the first frame of the recorded file to have a non-zero timecode, enter the
required value in the Offset In-point box.
Request the iTX Encoder to detect the timecode track in an SD video feed
For the recording of timecode, you can use the iTX Encoder to detect the timecode track in the
digital video source. (This is not necessary for an HD video feed.)
1.
In the Timecode Line (SD) box, enter the number of the line that the video feed carries
timecode on.
2. Click Detect Time.
The Encode Server checks the incoming feed for the timecode track, starting on the line
number you specify in the Timecode Line (SD) box.
•
If it detects the timecode track on this line, the Encode Server displays a confirmation
message.
• If it detects the timecode track on a different line, the Encode Server enters the correct
line number in the Timecode Line (SD) box.
Set the pre-roll time for a VTR connected directly to the Encode Server
For a VTR, pre-roll is the time difference (in seconds) between the point where the Encode
Server starts playing a videotape and the point where it starts recording.
1.
In the VTR Pre-roll Time box, enter a value for the pre-roll time.
Test the connection between an Encode Server machine and a VTR
Where an Encode Server is set up to directly control a VTR, you can test the connection
between the two machines.
1.
Ensure the VTR is switched on.
2. Click Detect VTR.
iTX displays a dialog requesting you to confirm that you want the test to continue.
3. Click OK to continue the test.
iTX checks the connection between the VTR and the Encode Server machine. It then
displays a dialog stating whether the connection is working or not.
4. Click OK to close the dialog.
You can view a report of the machine-control status under the Diagnostics tab.
