    lag on client monitor

    Hey there,

    I'm running MC 2018.8.0 on a 3.5 GHz Core Intel Xeon E5 Mac Pro (late 2013) with an Avid Mojo DX (2018.8 driver installed), and I've got a lag on my client monitor of a few frames as compared to playback on my desktop monitor + audio monitors.  In other NLE's, I've seen settings to offset such a lag, but can't find anything of the sort in Media Composer.  Hoping it actually does exist somewhere?

    Thanks,

    Aynsley

    Re: lag on client monitor

    You can fix this with a console command "moncondel #"

    #=number of frames.

    Re: lag on client monitor

    Nice one!

    Had the same problem in the new place where I'm freelancing. Turned out that it was the Sony TV adding a delay to the video (3 frames). Ended up monitoring the sound thru the TV (instead of directly out of the Mojo) and I'm now in sync. At least on the big monitor...

    Re: lag on client monitor

    We have the same setup, MojoDX with Client monitor and a big Sony TV.

    Client Monitor has a delay of 2 frames and the big Sony up to 4.

    So we have two choices, watch with client monitor in sync or with the big TV (sound through the TV) in sync.

    Re: lag on client monitor

    moncondel works, but it's not persistent. You need to set the value each time you launch Media Composer.

    As of MC 8-ish (I forget which release), you can now adjust this offset using the "Desktop Play Delay" setting.

    There's two values in there:

    "Desktop/Hardware Sync Delay Frames" 

    This will shift the position of the audio relative to BOTH your external video monitor and the computer display.

    "Video Sync Delay for Remote Client Milliseconds"

    This will offset both the video and audio coming from your hardware relative to your computer display. At 24 FPS, one frame is about 42 ms.

    "Desktop Play Delay" is listed as a 'Site' setting, so it's local to the machine, and doesn't travel with the project or user.

    I should note that we've been using this setting with AJA and Blackmagic hardware exclusively. I haven't tried it with Avid's own hardware.

    Desktop play delay only allows you to delay the display. You can't have it earlier so it wouldn't have been of any help unfortunately.
