    On older mac pros - approx indication of performance difference
    1080p
    There are 5 different prores codecs with very different performance
    Prores 4444 - 1layer
    Prores hq - 2
    Prores 422 - 3
    Prores lt - 5
    Prores proxy 6-8

    So you adjust for how many layers you need
    More layers- use faster codec
    Less layers - use slower ones

    A future version will support more outputs- when we figure out what the limits are in new mac pro

    Further testing on Number of outputs from the New Pro pro reveals that you can only get 3 outputs with a combination of DVI and HDMI. Apparently by using dual link DVI cables there will be more outputs available. I have ordered 4 dual links to see what can occur. You can connect 6 thunderbolt monitors - however not much use to us.
    We also found that HDCP can be implemented on some switches - we found injecting a Parrot into the chain solved that HDCP problem.
    I will let you all know the outcome of the Dual Link DVI testing.

    You have to use active dual link adaptors
    Which usually means they need to be the powered types

    I think display port triple and dual heads to go might work as well

    Some people have also tested x4s with 4k outputs

    Also there are only 3 output thunderbolt buses- they are paired up- so output monitors in some configurations need to be set up to take account of this

    Dual AMD FirePro D300 GPUs with 2GB of GDDR5 VRAM each
    Appears very stable running 16 streams of HD and 1 4k - before I had any frame rates drop below 25fps.

    Just to be clear.. that was 16 HD streams and a $k stream at the same time? what codec? Bitrate? Thanks for postin gthis

    I will look at the X4 and triple heads optional later this week, as we have all of those items.
    I was interested in seeing how many individual outputs we could drive in HD.
    Active Dual links have been ordered....will let you know how we go.

    The files were mainly AIC 1920 x 1080 from the stock Catalyst HD Library
    30fps
    64.05 Mbit/S
    And a 4k file that was Pro res 422
    3840 x 2160
    394mbps

    Using Dual Link DVI - I was able too get 5 (1920 x 1080) outputs on the Basic New Mac pro. 1 was a thunderbolt monitor and the other 4 were Dual Link DVI.

    I would post a screen grab - but can't seems to work out how to do this

    OK, So I am putting together a venue where we will have 3 plasmas in a 1 x 3 vertical config. I wanted to use a new mac pro with an X4. I should be able to take a mini-display port to dual link DVI, (bus powered ok?) and go into an X4. If I output 3840 x 2160 on the mac, and then use the X4 to slice it up into the appropriate orientation that should work right?

    They actually have 2 columns and I was originally going to just mirror them with DAs but is it maybe possible to have two X4s, running 2x4k and then?

    Anyone tried testing this setup yet? I have not had access to two x4s.
