We’ve calibrated zoom data with ReTracker Bliss and the Indiemark encoder in the Advanced calibrator without any issues, so maybe there is something specific going on with the Fizz? The Advanced Calbrator won’t let you proceed unless it sees the calibrator checkerboard property, so that’s also something to look into? 

Hi,

If the Camera Calibrator stops working at the second step (when it asks to zoom out to max distance), then it is likely that the Camera Calibrator doesn't receive the zoom data.
In that case, it is likely you don't get zoom data in every application.

Do you get zoom data in the Basic Calibrator?
The zoom data is written after the Z letter on the monitor:

The value should change when you change the zoom level on your camera.
After the F letter the focus data is displayed.

Do you get the lens data on the Zoom Factor and Focus Distance pins when using a Camera Tracking module in Aximmetry? https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/tracking/how-to-set-up-tracking-systems-in-aximmetry/#checking-the-tracking-data-flow
If you don't get data on either of those pins and you get data in the matching sensor pin, that means that the calibration file is not being used (for example you didn't specify a calibration file in the Camera Tracking module) or doesn't have relevant zoom or focus calibration.

Note that the Camera Calibrator can not calibrate focus yet. For that, you have to add manually the focus levels in the Basic Calibrator, as you did.

To open calibration file's zoom in the Camera Calibrator that was made in the Basic Calibrator, you have to fill out MaxZoom and MinZoom values in the calibration file instead of 0 values. You can open the calibration file with any text editor app, for example the Notepad:

However this will not affect Camera Tracking module or the camera compounds in Aximmetry.
The most likely source of your problem is that you didn't recieve zoom data.

Warmest regards,

Thank you for the feedback.  I can see the zoom data in the basic calibrator and I have confirmed that Axi is receiving all the data - tracking data and lens data for zoom and focus.  I created a new compound and added Camera Tracking and a Peeker for the key values to confirm data is being received.  One observation I made when I looked at the raw data values in Axi this way is the as I make lens adjustments I can see focus and zoom values updating on my Axi monitor with the peeker values, but when I stop adjusting the lens the focus values always land on 0 as if Axi is having issues reading the calibration file?

But do you receive zoom data in the Advanced Calibrator? Even if you have it called in Aximmetry, you need to set it up in the Advanced calibrator as well, since it’s a separate app. 

I am not sure given the advanced calibrator does not display values like the basic calibrator unless I am missing something?

Just check what settings you have in the Basic calibrator and match it in the Advance one. It’s easy to accidentally map the wrong device to either zoom or tracking device, and Aximmetry should really print out the values in the advanced calibrator as well to make it easier to see if you’ve missed something in the setup. 

I am 100% sure I have the same setup in both and the proper devices mapped - I agree, if Axi would expose the values in the advanced calibrator it would help tremendously!

Hi,

When you stop adjusting the lens the focus values always land on 0, does that happen in Aximmetry too, when you use a camera calibrator module with the calibration file? https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/tracking/how-to-set-up-tracking-systems-in-aximmetry/#checking-the-tracking-data-flow
It might be a behavior of the hardware and not calibration.

We added to write-out focus and zoom values in Camera Calibrator's preview to our request list and we will consider adding it in future releases.

Warmest regards,

Hi,

We are thrilled to announce that the issue you encountered has been resolved in our most recent update, Aximmetry Version 2023.3.1, which is now available. You are no longer required to manually enter MaxZoom and MinZoom values in the calibration file to see the focus calibration within the Camera Calibrator:

Thank you for your engagement and feedback, which play an essential role in our ongoing development and enhancement efforts.

Warmest regards,
