 This is a Gig-e vision camera

As yet Isadora does not support this. Gigevision cameras are great, but they are not widely supported by systems like Isadora. Supposedly TD has support for this, I didnt check though.

Two webcams on the same hub won't work.

 I believe Woland meant to say two identical webcams on the same USB hub won't work. 
This is a matter of the hardware having machining IDs, so it creates a conflict. Moving one to another USB hub causes each to have a unique address.
NOTE: not the next slot, but to another collection of slots. EG, you have 2 USB slots on the left of your laptop, and 3 on the right.. this is likely 2 hubs, so you will need one connected to each side

How did it work out?

I have used multiple blackmagic capture devices before - although not identical ones

these little guys are useful, connects via usb-c/thunderbolt: https://www.blackmagicdesign.c...

depends how many ports the macbook has. if its a new macbook pro you have 4 usbc/thunderbolt ports. what I used to use was an old Ultrastudio thunderbolt plus an old Intensity Shuttle USB3 on a 2015 mbp. Never had issues (well... there are always issues, but not in terms of having multiple blackmagic devices). the blackmagic utility is very useful in letting you configure each device separately.

probably too late but hope this helps

@DusX

thank you for your answere - we just filed a support ticket with the project file and crash reports.

@bonemap bit off topic from GoPro but I have been using the newish pihq camera with c/cs lens mount https://www.raspberrypi.org/pr... with a raspberry pi to make hdmi cameras - very few lines of python code to get full screen hdmi out. There are pros and cons of course - lots of lens options, but fixed focus. Lots of camera options can be fiddled with in code. Not many more lines of code to make a time lapse camera, and very customisable.

Does this mixer allow you to get video into the Live Capture Settings using the Blackmagic driver? Or????

And in Windows it's the same: the ATEM input is seen as a Webcam in Isadora, and you just set the driver to Windows NOT Blackmagic.

Hi,

PTZ cameras are one device option to look at. I am thinking perhaps the proliferation of gimbals is another - somewhat related device - that can be considered for Izzy plugin development. I have a DJI Ronin M and a Ronin S gimbal and just a quick comparison of cost suggest these possibly  provide good value and flexibility compared to the PTZ camera lineup - admittedly they are a BYO camera option. The PTZ cameras appears to have some shared protocol, but the diversity of gimbal makes and models are likely all proprietary. Still I would definitely use an Isadora Plugin that implemented gimbal control as an alternative to acquiring a PTZ camera. Specifically because the gimbal allows any number of camera types to be mounted and offer comparable functionality to PTZ.

Just a thought.

Best wishes

Hi there Taly!

So for formatting strings we can use the actor "Text Formatter". Double click on the actor and a little window will open, in that window we can use the P (for parameter) followed by an index starting from 1 to say what parameter we wish to use.

So let's say we have the text

"command=hello world"

and we wish to change the text after the = to do so we use the following.

"command=" P1

If we now press OK, mutate the input of the param 1 to text (simply connect an trigger text to it) we now see that when we change the Trigger Text input / trigger it that the output of the Text Formatter changes.

@ril SDI cable is not super expensive for 1.5ghz and can go easily 100m or more depending on quality. It is easy to repair on site and there are a lot of options, pretty close to the cables for AHD cameras. SDI is pretty specific so I doubt there are cameras that are "not specifically SDI but that do have that SDI output"

The mini recorder will work, but only at 1.5ghz rates like 1080i 50/60 and 1080p25/30 or lower. At any rate it is a good combination, the lenses are cheap and the security cameras usually have an OSD with manual settings.

Hi everyone ! Usb cameras have proven to be unreliable in low light situations. So I think this new option ... could you advise me and tell your experiences about black and white cctv cameras and if possible in color. What hardware is needed in addition to the camera to get into Isadora? What cables do you use and available length. and if it is compatible with Mac. thank you very much!

[Thanks @DusX ]

best,

You will likely get the best performance (for cheap) with old black and white cctv cameras.. running into some type of capture device.
Most webcams are pretty bad with low light, and have lots of auto focus, brightness etc features built in that can make things difficult.

@mark_m ah ok...thanks for the warning

Best,

@goddessmoon2017 so far the skeleton tracker needs NVIDIA cards for cuda acceleration and it is windows and Linux only.

It is early stages and resource heavy right now, and also still only available in the US and china. I had to get one forwarded from the US to develop with.

For sure it will get better and cross platform support but this is going to take quite a while to get there and then to stabilise (SDK wise)

Hi Michael

Many thanks for the pointers and the help.

All now works perfectly.

I have been a long time fan of Isadora and have only just come back into the realm of it due to a new job. I do appreciate the effort and advice I have received. It has been very helpful and has made me look good to a lot of people...:)!

Thanks again.

It´s free. NDISyphon

I should have said before, once Airserver has a connection to your device it streams it to Syphon or Spout. The advantage of Airserver is that as it doesn't necessarily simply mirror your device's screen; as the device sees an external display some apps, like switcher studio for example, just send the 'video output' without including all the GUI icons and other stuff that you often don't want on the image. It'll depend on the app, obviously, and how it treats external displays.

I used a (now discontinued) Nyrius Wireless HDMI live feed transmitter and receiver. The key for me was that the transmitter was small. In this photo, you can see the transmitter sticking straight up to the side of the camera (with the tape that says "DEMO" on it). We used a 90-degree HDMI connector to allow us to have it pointing up, rather than out to the side, so we could secure it to the camera. At the back of the camera, (with the tape that says "A" on it), is a portable battery bank, as one would use for mobile devices. This acted as the wireless power-supply for the wireless HDMI transmitter.

Note: Sometimes cell phones can interfere with the signal, so we had to make sure that the audience turned all of theirs to airplane mode or, preferably, completely off.

Optimizing for Coverage: I was at the edge of the rectangular performance space and the live feed operator sometimes moved all the way to the far end. We were having some signal issues, so I moved the wireless HDMI receiver to the middle of the room, in the grid, and used an HDMI-over-Cat6 extender in order to put it that far away from myself without needing a 60' HDMI cable. No more issues after that, as the camera was on average always closer to the receiver then it had been.

Best wishes,

Woland
