AIDA PTZ tracking protocol compatibility - Prof DE

 

Hi,

I would like to know if there is a way to receive position and tracking information from AIDA PTZ cameras. In particular we have the PTZ-NDI-12X that have the VISCA protocol over IP. We also have the Aximmetry Professional DE version, which has a reduced set of camera tracking protocols.

Maybe there is some protocol translator software?

Thanks in advance. Pablo

Visca is a protocol for controlling the camera and not really a tracking protocol. I know some cameras send back Visca positioning data, but I haven’t seen a single example of it working smoothly and precisely enough for professional results. PTZ cameras in general are not great for green screen productions and neither is NDI, due to small sensors and heavy compression. The Sony FR7 is the one exception, since it’s basically a FX6 with added genlock, mounted on a pan/tilt head.

Hi,

The VISCA protocol requires the Broadcast version: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/supported-hardware/professional-camera-and-object-tracking-systems/tracking-systems/#professional-tracking-systems

As @TwentyStudios mentioned, the VISCA protocol is primarily used for controlling cameras, not for tracking them. Therefore, when it does provide tracking data, it is usually inaccurate and has varying lags. In most cases, you could only use it to help set up or record static positions. While it would not be useable under live production to provide continuous tracking data.

Note that you can rent the Broadcast version of Aximmetry for a day to try out the VISCA protocol tracking.
I read into the PTZ-NDI-12X's manual, and it is not obvious to what degree the VISCA tracking would work with that camera model or if it would work at all.

Warmest regards,

Thanks for response Eifert.

Acabo de contactar a la gente de AIDA IMAGING y comentan que ya están trabajando para implementar Free-D en sus próxima línea de cámaras PTZ.

Consulto si con la versión Aximmetry Professional DE es posible trabajar con tracking de cámara con los protocolos que figuran en la lista en "Manage Devices"-->"Camera tracking" ó directamente no es posible...

Actualmente estamos usando con éxito la app Eye sobre IPhone 15.

Una lástima que la app no contemple 50 frames/s y que no active el estabilizador óptico de la cámara. 

Saludos!

Pablo

For FreeD you need the Broadcast version.

Sorry Twenty, and thanks for your comments.

The question in your language:


I just contacted the people at AIDA IMAGING and they say they are already working to implement Free-D in their next line of PTZ cameras.


I'm wondering if with the Aximmetry Professional DE version it is possible to work with camera tracking with the protocols listed in "Manage Devices"-->"Camera tracking" or if it is not possible at all...


We are currently successfully using the Eye app on an iPhone 15.


It's a shame that the app does not contemplate 25/50 frames/s and that it does not activate the camera's optical stabilizer.


Regards!


Pablo

Hi Pablo,

You need the Broadcast Edition to use Free-D. Each Aximmetry version lists only the supported protocols in the Manage Devices window. Therefore, anything you can set in the Manage Devices window in your version is also usable in your version.

Regarding the Aximmetry Eye, it's not that Aximmetry Eye doesn't support 25/50 frames per second (fps), but rather that the phone itself doesn't support those frame rates. Even if you can set those frame rates in a camera app, the app would actually record in 30 or 60 fps and then convert to 25 or 50 fps by dropping the additional frames. You can achieve the same in Aximmetry's Composer.

We can add the phone camera's optical stabilizer to our list of feature requests. However, I suspect it is not possible to implement that because iOS likely doesn't provide access to the optical stabilizer's adjustments, and hence we would have no way to adjust the tracking to it.

Warmest regards,
