I am using several panasonic lumix DC-BGH1 cameras.
The settings of the DC-BGH1 camera are as follows.
– System Frequency : 59.94Hz(NTSC)
– Rec Quality : 1920×1080, 29.97p
– SDI output resolution : 1080p
And the multi-camera system configuration is as shown in the figure.
(Tentacle and camera are connected using BNC connector.)
The camera’s time code setting is set to FREE RUN, NDF, and TC IN.
When recording a camera with this configuration, the timecode does not match.
Am I testing the wrong way?
I want to know which part of the problem is occurring.
(When testing with another camera, Panasonic AG-HPX255EN with the same configuration,
We confirmed that the timecode matches exactly.)
Images used for synchronization analysis are saved directly from the camera to the SD card.
When I checked File-TC using Premire pro and TTS, I was shooting the same screen with the same timecode.
The problem is that the timecode displayed on the screen through SDI out does not match. (Since it will be used for streaming, it is important that the TC displayed on the screen is synchronized.)
For this reason, the TC is actually being synchronized,
I am thinking that there is a problem in the part where the camera outputs the TC to the screen through SDI.
And I plan to use 16 cameras later, and there was no splitter that could input TC to all 16 cameras in one Tentacle.
(The splitter I found is AJA C10DA, which receives 1 input and has 6 outputs.
As a result of inquiring with AJA, I received a reply that it is not recommended to send TC by connecting multiple splitters in a chain.)
Therefore, the test was conducted in the direction of matching the snyc by connecting one tentacle per camera.
