Signifcant Grading Latency On the Video Out Monitor

[Marcus Smith]

HI Michael,

Thanks for responding. I read your post ages ago an remembered it incorrectly. I thought you were referring to playback and now I realise you were addressing grading as well.

The word from Black Magic is that you should expect 6-7 fps latency whilst grading on the Mac. This is a world of time for professional video applications. On long form it can add up to hours of delay for a single project, not to mention frustration for a fast operator. Even Apple Color can be made to be significantly less.

My final bit of investigation is to find out whether the Linux systems have similar latency. If they do, Black Magic’s “real time by design” slogan is misleading. We bought many systems based on this promise only to find out the opposite.

Have you worked on a Linux system and noticed any Latency?

Thanks,

Marcus.

I know this an old post but curious as to what transpired from this?
Running Resolve 8.2.2 on Mac Pro 2.93 32GB/ATI5770GUI and CUBIX with Quadro 4000(2), REDROCKET and DeckLink Extreme 3D into a Flanders LM2461W.
My issues mostly is the major lag in playback.
I cant say for sure if we have any issues with the Grading since we just got the system together today.
