Probably a longshot, but...

Does anyone have experience with #barco #sp4k #cinema #projectors? And specifically, creating an image macro for a specific aspect ratio?

Had a real fun time troubleshooting a #projection issue this evening.

After a summer down for HVAC reno, the theatre fired up their #barco #sp4k projector up for the first time in months.

All was good, until we noticed this strange liquid/smoke motion, distortion. Definitely not coming from source or cable - it's in the light.

Went up to the projection booth just to check things, and it was about 50°c in there. No joke. All the warm air from the building was being forced up into the attic, and down into the booth.

After opening all the doors and windows, we got the room cooled down to a reasonable 35°c, and the distortion went away.

Wild. The video failed to capture how disruptive it was - very prominent on a white bg.

Anyone have any experience with #aes67?

I'm working in a theatre to consolidate a bunch of ad-hoc networks into a nice VLAN segregated network. I'm running an #openwrt router with a #cisco 2900-x series switch.

I have a #barco #sp4k projector and #dolby #cp950 audio processor, which uses 8 channels of aes67.

Currently we have a direct link over cat6 between the projector and the processor.

I would like to put the AES on the same trunk line as the rest of the network.

The network setting on the Dolby AES67 has 2 IPs:

1) static source IP: 192.168.1.151
2) destination broadcast IP: 239.81.83.67

The Barco doesn't seem to have any configuration for audio network.

My thinking is I should be able to change the source IP to something on the relevant VLAN: 10.10.11.151 (VLAN 11).

But what about the multicast? It seems common to be on a 239.0.0.0. Do I need another VLAN to cover that network?
