Hi all, as we get closer to going back on location I thought I'd do some testing of my TC2E to check its latency to see if it will work for Imag. My testing method is as follows: I have a BMD Ursa Broadcast camera connected to the switcher via SDI. I have a black burst generator connected to the switcher and camera. The camera is set to the same format and frame rate as each session. I have a laptop running a millisecond timer. I am shooting the laptop display with the camera and outputting that signal on my critical monitor. To find latency, I take video of both screens, find a clean frame of both images and do some simple math. The results were surprising. Genlocking the system resulted in significantly higher latency. I then went on to test adjusting the camera lines of timing and the switcher H & V position. The camera lines had an effect but not in the right direction. Switcher H & V had no effect. Below is a table of the results. I'd really like the system to be around 60 - 80ms; thoughts? Your feedback is welcome. Anyone using a TC2E for Imag out there?
|SESSION||SOURCE TIME||OUTPUT TIME||CAMERA LINES||LATENCY (ms)|
|CAMERA LINES||LATENCY (ms)|
|SWITCHER H POS|
|SWITCHER V POS|
