Monitor Latency Test: SDI Cable Delays | Sony, SmallHD, Osee, Atomos, Holyland, Seetec

Thanks for this test. What kind of camera is feeding the monitors?

@@modernhumantv red Komodo

​@@HugoWill Thank you! While I've not tested the Komodo myself, all camera's SDI ports do introduce some latency, before the monitor and / or wireless TX/RX. The Alexa family is apparently the best at less than 20ms, which is what I read online, that's less than 1 frame of delay, if true. I tested my Varicam LT and I'm getting around 30-50ms, when I run in 60fps VF SDI mode. But I've heard Sony Venice 1/2 have around 4 frames, which would be around 160ms. For reference at 23.98FPS 1 frame = 41.70ms. Very happy that you compared Atomos to SmallHD, because I'm thinking of getting one of those and wanted to see if it was better than Atomos and it appears so. Anyway, Just some thoughts. Thanks again for doing the test.

@@modernhumantv interesting, I haven't thought about cameras actually could also send delayed signal. but makes sense. gotta test different cameras one day too

For other viewers watching in a browser, use the , and . keys to move frame by frame to check the latency :)

[@AnotherCameraChannel]

Pretty much they all had a minimum 2 frame delay, with the monitors called slower being 3 frames.

great idea. thanks
