Isadora is not officially supported with multiple graphics cards. It can be done but we can't provide support, there are just too many factors.
Beyond that, multiple cards introduces some bottle necks that are very hard to get around... in the end it generally will provide less performance.

I would recommend getting 1 graphics card with lots of RAM, and then a Matrox Quad Head 2 Go. This will give you 4 outputs from one DisplayPort. with a NVidia card, that leave you 3 more available display connections (make sure you have the physical connections) for a total of 7.

I have really good experience  with entecPro. Also with DmxKing. But Enttec really  reliable.

Hi All further to my 'which depth camera' question (unanswered!) is this one a good option:

It seems pretty good from the spec though I am far from being a expert.

Thanks in advance, David

I would be quite interested to know the answer to this. I use the d435 but they are hard to find currently and the d415 seems to be in stock in more places currently. Let me know if you do test it. Or maybe I'll try to get one to try also. 

@eamonn Same!

@mark_m

With the Raspberry 4 you have two independent HDMI outputs. And using a program like  Pi Presents you can manage many control features for videos.

Hi I am now finally ready to begin using a depth camera with Isadora. I work with a dancer and want to do some interesting stuff! I remember being advised to go for an Orbbec but this was a while ago and things move quickly so what should I go for? Maybe there is no simple answer. Any tips gratefully received! Cheers, David

@citizenjoe @dbini @Fred

Thank you so much all of your for your suggestions / advice, recommendations, and shared experience.

You've raised some really interesting questions about method - IR light stage or performers, for example.

I'm going to go and sit in the tent with the lighting techs and the riggers and ponder the variables, and will report back.

Thanks again!

And John, would be great if you with us in wet, windy Wales, on an industrial estate near Llantwit Major!!

Cheers Mark

usualy there is no need to have the audio being routed through your video chain. It is common practice to have them separated until the point, where they are streamed. This could be OBS on the same machine where Isadora runs (without audio through it), a separated computer or a hardware streamer like a Aja Halo. Only on this final point they get married and streamt right away. You might have to manage some latency issues by delaying audio or video on some point, to have it syncronised. This can be done by OBS or some hardware delay devices.

It is the same for live TV productions or any other, stream or recording.

The only reason to have audio going through izzy, would be effects or generating them from there.

@mark Thank you.

@citizenjoe @DusX

Just updated my post above with working solution. Hurrah!

@mark_m

Thanks for the reply Mark.

I've used NUC's in my streaming rig, Dante Audio rig, and a photo booth, I love the small form factor and flexibility.  

I'd love to hear from someone who's used or is using a gaming laptop too.  I have zero experience with those😎

Did the nuc I lined to seem sufficient enough for I3?  It's more than enough for the ETC Nomad software.

Thanks again for your insight.

Peace,

Ant

This looks like a good way to get 3 x 1080p 60 HDMI signals out. supports M1 chip. on Kickstarter with 27 days left.

4 separate outs playing still images at 4k ought to be just fine?

 Yes, still images will be rather light weight.

It seems like your HDMI connections should do the trick. ( I believe AMD allows 6 displays connected total? )

Videos will greatly depend on your drives. If you have multiple fast internal drives, and split up the video so that they are located across the drives, you should be able to make it work.
It's worth doing drive speed tests for each drive, as well as, working out the transfer requirements of each video type (4k in X codec requires MS/s)

@GertjanB, we are looking exactly for stuff like this but I'm not sure if I have the know-how to realize that

The great thing about simple dc motors (not servo or stepper) You don't need a lot of know-how to make it work you connect them to the power and they  work. if you change the wires it turns the other direction. 

This is where I learned to wire a windshield wiper motor the great thing is that you can use it as a stepper motor with only one step:

To make It change directions I used this whiring diagram:

This is all you need. (for the relays you can use dmx relay boards there you give a dmx channel to a relay.)

In Isadora you can make a user actor that sends out 2 dmx channels where you can make the motor run one way or the other.

If you want to make it run slower it becomes a bit more difficult, you need a PWM.

@whatnao How much displays do you want to connect? And what resolution do you desire? I've used simple USB-C to VGA-Adapters to connect three projectors to my 2018 MacBook Pro with similar specs than yours and it worked perfectly well. I also used USB-C to HDMI adapters with to HD-Displays and it worked fine as well. 

@thatmattrogers

Hi,

I can confirm 4 x USB camera inputs through a OWC thunderbolt 3 usb dock to Isadora Live Capture Settings.  I also looked at adding additional RGB through the OpenNi Tracker Beta plugin (because it also captures RGB from Kinect and Astra cameras). However, I could only get the depth camera source (the OpenNI Tracker plugin RGB camera source appeared disabled (black screen) while using the Live Capture Settings USB video input).

Best Wishes

This is a great tool, thanks for sharing.

It may be more accessible to users if you upload it to the Add-Ons page. Posts can get a little buried in the forum over time.

Awesome find!

PS I can receive data from the button (eg send letter 'a') via the Keyboard Watcher!

 I have used this button for a project in the past. I didn't even consider using HID, I simply did as you mentioned and used the Keyboard watcher. It worked great.
