Ultra Studio Express Lag
Posted: Mon Jun 10, 2013 15:33
I've been testing an SDI input BlackMagic UltraStudio Express this week and I'm having a lag issue.
If I set a Sony EX3 to 1080i I can see a 2 frame delay between the sdi preview monitor and the resolume control screen and another 2 frames from the control screen to the fullscreen output. 4 frames in total
If I set a Sony EX3 to 720p I can see a 1 frame delay between the sdi preview monitor and the resolume control screen and another 1 frames from the control screen to the fullscreen output. 2 frames in total
I'm pretty impressed that resolume can keep the delay down to 2 frames. However I'm have a strange video lag. Any fast moving objects in the frame appear to have the effect of dropping the frame rate down to 10fps, but resolume still reports that I'm at 50 - 59.94 fps.
I'm running this off a new 13.3" MBP i7 that only has the HD4000 GPU
I'm goal is to get a mobile laptop setup that I can use for basic corporate imag/slide.
