Hey thanks, the reason I had to post is that b&h is closed for a religious holiday.

I have been using ATEM for a few years, great stuff, no scalers on inputs so all input resolutions and frame-rates must match- it still gives you one input at a time (if you use it to feed a capture card).

The USB 3 capture built in to the old 2/me is not worth using and the ATEM television studio USB 2 is h264 encoded and cant be used for capture.- you will need another capture device There is a an ATEM osc bridge that works with late but not latest firmware versions, the atem is a mixer and will not get you 3 simultaneous cameras, the tv studio model also does not have aux outputs so if you use it as mixer for your outputs you have no aux feed for your capture box. https://github.com/danielbuechele/atemOSC Your original question asked about 3 cameras into izzy- this does not help for simultaneous capture you though so it is unclear what you are after. If you only need one camera at a time then you have lots of options and dont need 3 inputs just some kind of switcher- as in the other thread knowing if you have to have smooth transitions between cameras with effects changes the requirements. For simultaneous inputs the other thread has some info, but there is nothing that will really work for gen 1 thunderbolt, apart from a quad split device running to an HD capture input. Your USB 3 is the only option to keep an output free for the projector. The blackmagic clean switch router is another solution that can help you. Depending on what you see in your future for hardware you may be better of looking at other solutions as the cost of all these little bits will add up. Some more info about your use case can help.

I just used your PS3 to Syphon software for this little video @Fred 

Thank you! https://www.youtube.com/watch?v=W5SM9bJyu_c 

I have a 7750 eyefinity board and am using all 6 miniDP to VGA outputs at 1024x768 . It was working mostly ok until I figured that I had to make it run at x16 link instead of 8x. It has been running nice and smooth ever since. with catalyst 15.9.1 Beta. I know the matrox moards use the AMD chips but I don't know more about the software or issues.

I can only echo what Michel has said.

They are great products but the settings are nightmare. The new update is a little better and a bit more functional - but really a full auto-detect would be ideal.  This may be the syphon app you are talking about, but for future readers here is a link with download: [ ](http://vdmx.vidvox.net/blog/black-syphon) [http://vdmx.vidvox.net/blog/black-syphon](http://vdmx.vidvox.net/blog/black-syphon)

I love my MacBook Pro Retina. Mine is 3 years old now but still works great. The dual thunderbolt ports are brilliant but do require a load more cables and adopters!

No - but something that might work well with it in the future.

"High-speed Projection Mapping System (Prototype)

Panasonic will unveil, for the first time in the world, its projector technology for high-speed and synchronized mapping on unmarked target objects."

Might be connected to this project

@fred i do post processing. but i will take a look at your ps3 to syphon app. somehow this passed my attention :(

thanx for the info

I am currently running one Intensity Shuttle and one Ultrastudio SDI, one capturing composite SD and the other capturing HD SDI.  Both are using USB 3.0 and I'm having no bandwidth issues.  It does seem to affect some other USB devices, such as my Enttec and my Matrox triplehead though, but I am wondering if that is some sort of driver conflict rather than bandwidth.

I am using a mid-2012 non-retina Macbook Pro. Craig

You are welcome.

I forgot about the sudo part.

Is Trim necessary? It depends on what you read and I've certainly read accounts of SSDs getting very slow over time without TRIM and Crucial's advice is to have it enabled despite their drives have Garbage Collection built in. So with something so easy to do I wouldn't hesitate and enable TRIM. All Apple flash drives have it enabled by default so they see it as a positive so I guess it can only help. Paz, The super quick boot times and application loads soon become the norm so never go back to a computer with spinning disks, it feels like there's something wrong it. 

very interesting indeed. i already ordered a little engine..;) i will give it a try next week and post the results

Thanks @Marci I need to go through all this properly when I get a spare hour. Sounds awesome! The fact it can all be controlled via Izzy is just incredible! Love it. I will come back to this post and read it all properly. Thanks for sharing!

Thanks

Fred

Thank's, enjoy your tour !

I get no noticeable delay from using the extenders (ie less than one frame).

Even though some extenders say HD they do not support the full bandwidth so you will find that the extenders that use a single RJ45 cable maybe able to send 1080i50 but not 1080p50 (as it is double the bandwidth). There are some of the high end extenders that can do the full res in one cable but they are expensive, some have a remote system where only one of the boxes needs power (2x RJ45) and some can do a lot of high resolutions (2x RJ45). There is no standard and these boxes do not convert to and from a standard so the sender of one company will not work with the receiver of another. There are a lot on the market (HDMI over RJ45), but you need to check and test to find the one you like. HDMI to SDI on the other hand is a standard and although it technically does less (in terms of non SMPTE resolutions), IMHO it is a much better way to go.

So the question is :

Did anyone tried using 2 x Blackmagic PCIe mini recorder in an "old" macpro ? Thanks for feedbacks Mehdi

Thanks a lot for your good news, DusX.
 I'm only used these last years to a MacPro full of (almost vintages) graphic cards, or old MacBookPros with Radeon or else...
So I am a bit surprised but I guess Intel chipset has improved since last century!
 And I haven't  think about the mac-mini, and gonna study this possibility...

I'm still running Yosemite.

It's also worth mentioning that you can, in fact, use a triplehead with three separate stages, by using a handy feature in the Isadora preferences 'Stage' tab.  You can set a stage to be 'left third' 'middle' or 'right third' instead of 'full'.  This essentially takes the large triple-wide output and splits it to match the three outputs of the triplehead, saving a lot of programming work.
