Encoder 1Gen+ (refresh)
Hardware (Proposal)
For encoders, we use h264 as the only codec. FFMPEG has good multicore performance for this codec, which outweighs the need for good single core performance. We are hence looking into a Ryzen based setup.

This would be applied to encoder 5 as encoder 5 has already the desired SDI card configuration of one DUO und 2 mini resulting in 3/4x IN and 0/1 OUT depending on card configuration.

Intel-based board with 8th generation 6 core processor. Higher single core yield. The lack of two additional cores could be compensated e.g. by making use of VAAPI for generating previews sent to the GUI (note this is also an option for the Ryzen GPU, incl. MPEG2 de/encoding, e.g. for the background loop).
Progressing from here
Encoder
Evaluate single setup, order 4 more later. We already have 2 boxes with DUO decklink cards. We should by 4 more duo of current generation. At least SDI in is already supportet so we have no disadvantage. This would cost us about 5000€ which we can we probably can add as congress budget
Usage of the old boards
We could buy 5 of these 1HE micro ATX cases. This would allow to add 2 more reencoders in Berlin and maybe 2 in Hamburg. And a 5. one in the server case. We could also try to build 2-4 boards in a huge 3HE case. This would mean we need to drill and wire everything ourselves. We could also put the 5. at CCCB to have a test machine. We would need power switches and KVM solution that works over LAN this will cost us another 1K +/- in total
We could build 1-5 more encoder PCs
We could ask the Erfas who are building setups right now if they would want the HW
