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

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

I use pro-res 422 LT if it is something with text that needs to be very clear and readable or things that are going to have a close more critical viewing location. Other than that pro-res proxy typically works fine and you can't really tell the difference. You will be able to run MANY more layers in proxy then with AIC in any testing that I have done, so I prefer to use it if I can.
We have some mac minis that we can run 6 layers of 4352 x 720 without a frame drop at 30 fps in pro-res proxy, so mac pros will smoke…

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

I am very happy for the update, will try out as soon as possible...

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

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.

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.

[Mr_P]

Yes - should work. We've done this...

You need to use an active Dual-Link DVI adaptor to connect to the X4
But - do test the playback and ensure the movies are running at the correct speed - don't just rely on the frame counter... check against a real-time source.

I would use the DVI-DA option rather than 2x Datapath X4 as will put less load on the system (and probably be a cheaper option)

However, the image rotation can be done in catalyst with the mix windows... you don't have to do this with the X4.

Whatever you do - TEST TEST TEST... MacPro 6,1 and mavericks are new technology and we are finding new idiosyncrasies every day!...
