Hi.

Using the "well known" user actor of just one input and one output I've noticed that it sends out a trigger whenever I enter the scene.
I guess this is probably not meant to be this way.

@aikia

Sorry for the late reply. I'm quite busy these days. I'm using analogue DAHUA cameras 2MP with colour and night mode, manual or automatic setting for gain, exposure and shutter (this is an important feature, since you really don't want to have automatic exposure changes when you're trying to track something) and a zoom of 2.7 to 13mm which is great to be more flexible to place the cameras (I get as far as 25m from stage. I track using infrared (night mode) and reflective 3M wear on the dancer, and increase the shutter so I only see the reflection and anything else is black.

When I'm very far away I've used a cheap IR flood light to improve reflectance. It does not interfere with the video, nor the video with the camera.

The model of my camera is: DH-HAC-HFW2241TUP-Z-A

These are common bullet cameras, but If I was to get new ones I'd probably go for the PTZ (not sure if those have night mode). I use them in CVI mode and usually have a 25m coax running to the DVR.

The DVR model is also from DAHUA and I can connect 4 cameras to it and view them either in full res 1080 or a split screen with all cameras at the same time at 720.

Model DH-XVR4104C-X1-BL.

I had some issues with my BM-shuttle not recognising the res/freq combination output of the DVR so I had to output at 720. But still fine.

And that's it pretty much.

Cheers

We'll post a lot more details, but we were just able to drive a cave like immersive museum in Fortaleza (Brasi( also with izzycast). * Full HD projectors on a Blackmagic Decklink quad (8 configurable sdi input or ouputs in Full hd). An all on a macbook pro m1 64 GB ram 4TB HD under sequoia

More to come !!!!

@Armando This was told me to me by Sean manton who imports Blackmagic in Canada. I am sure it wirks I tested it end used itfprofessionally for a while in big 7 cameras streamings and hybrid events.

@mark_m Sure, but I can assure you that wirh a consumer standard hdmi cable I can control in the cameras drom the atem software in my mac Iris, blackpoint, primary color wheels white balance and iso at least. I an even do macros to change all of this at once (needed in some shows where we passed from vey low light to full powe lits in 2 seconds, Si I am sure the HDMI cable passes this info, plus le timecide (it is the mester and the cameras become slaves) If you purchase atem OSC you shours be able tocontrol okll of this via isadora at minimum.

@jrhooker FOr starters I'd exclude projectors that are not controllable vie ethernet PJ linl and that don't have sdi input (although in the price range all of this should be standard

@josharoo4 SOrry not sure have understook I had the 8 outputs Plus I have a 4 hdmi blakmagic input card on the same sonnet ahd they live together and are recongnizerd by the desktop video software... You couldn't activate the 8 outputs ?

Thank you DusX,

You are correct. I now have the 'shapes' actor working properly. 

However, I am using a GLSL Shader to create the video I want to use as a transparent image. And I think you've also helped me there as well, as the shader does not have a transparent background. I will consult ChatGPT to see if it can help me add one.

 Also, I should say that it also works great to output 8 separate video feeds. I had a video art project up that was using 8 outputs via the Decklink quad 2 and the Sonnet and then 4 outs from Izzy via thunderbolt to HDMI adapters for a total of 12 outputs. Ran very smooth and had almost everything at 1080p29.97. One issue I ran into was that I did need to reassign or toggle the Blackmagic outputs each time I restarted the machine. Went into the Stage Setup menu and just unclicked and reclicked the checkmark for each Blackmagic output each time. 

It does work with isadora on a mac and it works great. Ive done a few installs with this exact setup. I used the Usb-c Sonnet ePCI box and the Decklink quad 2. Works awesome. My limiting factor was that I could only use the 4 inputs that isadora allows so I set it up to take in 4 cams and to output over sdi to 4 output devices (projectors in my case). I did have to move over to qlab when I wanted to get all 8 inputs into the computer (a mac studio with the Sonnet box).
