Hi!

We are using Aximmetry 2024.3 DE, tracked cam with Canon N700 and FreeD.

I noticed that we didn't get any depth of field in the scene even when we put our object close to the camera.
The whole UR scene stays totally in focus, you would expect the scene to blur realistically behind the billboard.
If I turn on the manual lens option in the input settings it does work, but then the zoom factor is only showing in the cam, the scene does not zoom with it.

We used the camera calibrator (with checkboard) to calibrate the Canon N700 via the FreeD protocol.
The calibration profile XML is selected in the input settings.
During loading I see the following error message:

Setting mode "CANON N700 cam3 241009" for device "CameraTracking: Free-D: 10.86.49.226:50000 / Camera 3"
Loading Calibration Profile "CANON N700 cam3 241009.xml"
Profile contains no tracking calibration data

Is something missing in the calibration? And is that causing the missing DOF?
Or is there another solution?
Any hints are welcome!

Cheers,

Dennis

Hi,

When you turn on the Manual Lens option, it will overwrite the zoom value coming from the Canon N700.

The message "Profile contains no tracking calibration data" might occur because you didn't select PTZ as the tracking type when creating the calibration profile in the Camera Calibrator. More information can be found here: https://aximmetry.com/learn/virtual-production-workflow/tracking/camera-calibrator/#introduction

You are missing the DOF because to use your camera's focus data, you need to perform focus calibration, which is currently possible only within the Basic Calibrator.
There is a helpful comment here suggesting you might want to manually control the focus instead of doing a focus calibration: https://my.aximmetry.com/post/3383-ue-tracked-camera-focus-distance-with-pt
Note that you can load the calibration profile created in the Camera Calibrator into the Basic Calibrator. This allows you to start with the zoom calibration points and lens calibration; you will need to add 4-6 focus points per zoom calibration point to calibrate focus. More on the process can be found here: https://aximmetry.com/learn/unlisted/for-users/basic-lens-calibration-without-lens-distortion/#focus-encoder
