Can I make AR without a tracking camera?

@huseen: If you move the virtual camera in real-time, the AR objects naturally wouldn’t align to the physical world, so why would you?

Hi,
You can use AR camera compounds without tracking in Aximmetry as long as you do not move or change the perspective of your real-world camera during production.
You will need to set the ORIGIN panel’s Delta Cam Transf parameter. You can even use the Detect Origin feature to assist with this: https://aximmetry.com/learn/virtual-production-workflow/tracking/advanced-information-and-features/camera-and-head-transformations/#origin-panels
If you place the Detect Origin feature’s ArUco marker at the location where your AR model(s) will be, you will only have to position the AR model at the zero point in your virtual scene (origin). This way, you do not even need to manually place your AR model relative to the camera.
Additionally, you should set a zoom value similar to your real-world camera’s zoom level. If you know the zoom (in mm) of your real-world camera and its sensor width, you could set the zoom through these parameters accurately in Aximmetry:
Enable Override Sensor Width and enter your camera’s Sensor Width value.
Enable Override Zoom and adjust the Zoom value until the ON SCREEN panel’s Lens display shows the same mm value as your real-world camera. More about the Lens display here: https://aximmetry.com/learn/virtual-production-workflow/green-screen-production/tracked-camera-workflow/cameras-control-board-of-tracked-camera-compounds/#on-screen 
If you do not know your camera's sensor width, you can still enable Override Zoom and simply adjust the Zoom value until the zoom in the virtual scene visually matches the zoom of your real-world camera.
Warmest regards,

Hi,
If you are asking why Aximmetry hasn't produced a tutorial video on this topic, it is because we have not released tutorial videos in recent years. This may change in the future, but our current priority is to make the online Learn documentation as comprehensive as possible. At the moment, details about AR production in general are still a bit lacking in the documentation.If you are asking why there are no third-party videos on this subject, it is likely because productions that use AR or include AR elements are typically large-scale and use tracked cameras. On the other hand, without tracked cameras, AR simply becomes almost like a video overlay, which isn’t particularly impressive or visually compelling for a tutorial or demonstration video.
Warmest regards,
Yes, but it won't follow your camera.
