Hi,

You can synchronize animation between different machines and also between the Digital Extension and the LED walls. However, the latter won't happen automatically.

You are likely experiencing the animation being out of sync with the Digital Extension because you don't have a Picture Delay(s) set:

If you don't set a Picture Delay and leave it at 0, the Digital Extension will fit nicely on your LED wall's image. However, the animation will differ between the LED wall's image and the Digital Extension's image (meaning the animations/movements will occur sooner in the Digital Extension). Additionally, switching between cameras will be out of sync.

If you set the correct Picture Delay, then animation and switching between cameras will be in sync. However, the Digital Extension fitting around the LED Wall will be less accurate. If you render the Digital Extension separately, then the animation and switching between cameras will be in sync, and the Digital Extension fitting will be accurate. However, you will need at least two machines and must set the delay between animations or events in the Flow Editor.

You can read how to use two machines like that in the Switching Between Cameras paragraph in the documentation: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/led-wall-production/using-led-walls-for-virtual-production/#switching-between-cameras

Note that Nvidia Quadro Sync is not yet fully supported. Your ADA cards will still be genlocked, but each machine might have a slightly different delay. This can become a visible issue when using more than one LED wall. However, in the Digital Extension, you probably won't be able to notice a one-frame delay.
You can fix such delays by adding a one-frame delay using a Delayer module to the LED wall output that is not lagging behind:

Note, that in a future release of Aximmetry, Nvidia Quadro Sync will be fully supported. Additionally, there will likely be an automatic Picture Delay calculation option and the Animation Delay process will be simplified.

Warmest regards,

The delay setting here only seems to work for switching between multiple cameras, setting it doesn't alleviate the digital expansion and the asynchrony of the animation within the LED.

Is there any other way to do it?

Hi,

It could be what you are experiencing is the asynchrony of the animation is actually the imperfection of the Digital Extension fitting. By adjusting only the Picture Delay, you can rectify the animation delay no matter what. However, doing so affects the accuracy of the Digital Extension fitting around the LED Wall. This inaccuracy becomes noticeable only when you move the camera. And this fitting inaccuracy can give the impression that the animation is out of sync. This can be rectified by the multi-machine setup where the digital extension is only rendered by the controller machine.

Note that some level of tracking inaccuracy is inherent in LED Wall production, as it is impossible to predict exactly where the camera will be positioned in the future. But you can mitigate it by reducing the delay between the LED Wall and your computer and your tracking. Additionally, ensure that Aximmetry's In-to-Out Latency is set as low as possible.

To debug the animation delay and see how the Picture delay fixes it, you can render each frame's index number and compare the values displayed in the digital extension part and the video input. For example:
In the above image's red rectangle, a video image is rendered with the frame index number displayed multiple times. This image is then connected to the LED Wall compound. In your studio, position the camera so it simultaneously captures (frustum) both the LED Wall and the Digital Extension.
In the image above, the output of the LED Wall compound includes delayer modules, which display frames at one-second intervals instead of the actual frame rate. This allows easy comparison of the frame index numbers on the LED Wall with the Digital Extension in the final image.
Increase the Picture Delay by the difference observed between these numbers. Once adjusted correctly, all the numbers should match, ensuring there is no delay in the animation.

Warmest regards,
