They're Back! - Digital 'sparkle' / artifacts on SDI Inputs and Outputs

Hey all,

Just ran an event for a client using one of our TC1 units. Upon review of the recordings we are noticing the digital artifact / sparkle's that seem to have been an issue on SDI inputs across several Tricaster units.

We've seen this issue on another TC1 about a year ago but were able to resolve it via a software update and a CORE update.

I've tried both updates on the current unit that is experiencing the issues but, unfortunately, nothing was resolved.


I've tried different cameras and SDI cables but the issue persists across all SDI inputs. NDI inputs and internal graphics are not affected but the SDI outputs seem to also add the digital noise to the signal. So this definitely seems like an issue with the physical inputs/outputs themselves.


Current software build is:

TC1
Build Number: 8-5-251215C

CORE update was forced from the C:/Program Files/Newtek/Drivers/WDF folder and the unit was allowed to sit for well over 5 minutes powered off after the update process.

Vizrt Support came though with a fix. Adding this in case anybody else sees this issue in the future.


Please download and install Core D208 for your TC1, this is known to fix the sparkles.

I would also check and see if the NVIDIA driver is set to Max Performance, if it's not then please change it, this is known to also fix issues relating to pictures and encoding.

Let me know if this works.
