Sync a video clip on two halves of a Ledwall

Hello,

we are struggling having a video clip playing on two halves of a ledwall in sync. The ledwall is in nvidia sync and genlocked, but still the video is not in sync and is clearly visible the line between the two halves.

What can I do?

Any help? I use a splitter to send the clip to the two halves, but the sync is a little off. While if I load an Unreal scene in the same flow is in sync.

Maybe is the splitter node?

Hi,

I assume you are running a multi-machine setup (more than 1 computer running Aximmetry).
The splitter module will not introduce delay per computer.
Probably the triggering of the video playback is not in sync. This is natural if you are using a setup where the control machine only renders the digital extension and this log message appears:

In this case, you will have to set up the logic under the Animation Delay paragraph here: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/led-wall-production/using-led-walls-for-virtual-production/#animation-delay

Otherwise, this could be for example due to the video taking longer to load on one computer or due to networking.
If this is really the issue, then you can do the following to add delay per computer for the trigger:

Hi,

With Aximmetry 2026.2.0 BETA, a new Strict Sync option was introduced. If your setup is properly genlocked, this should make the previous fix obsolete.
Important: it is strongly recommended to update the firmware on the RTX PRO Sync card to version 3.06 or later.
