    Hello,
    I’ve been experimenting with sending frames between VDMX and Max/Jitter, I’m noticing irregular latencies between apps. At times there can be 1-1/2 frame delay (1080p 25fps), is this expected behavior? If not is there something I’m missing? I’m using as efficent code as possible within jitter.
    Thanx!

    How are you measuring latency?

    Hello Vade,
    Thx for the reply.

    I’m outputting a frame counter generator from Final Cut X out via HDMI on my MacBook Pro. This feeds into a MacPro 2013 using a Blackmagic Ultra Mini Recorder. I’m using BlackSyphon for capturing on the MacPro.

    I’ve uploaded a basic diagram – HERE

    There seems to be inconsistency between apps, a frame delay at times and other times will stay in sync, no delay. In Jitter, when outputting jit.gl.syphonclient to a matching dim matrix and back to jit.gl.syphonserver, this can add another frame of delay?

    Is this to be expected?

    Anyway, thanx for your great work.

    Bill
