RAM
Video processing requires a large amount of RAM and if you are using IP sources this will increase the buffers required for decode and encode.
We recommend 16GB per 1080 50/60p Source
It’s important in any system to have at least 4pc RAM for each CPU, 6 or 8pcs or more is better
e.g. 4x 8GB, 4x 16GB, 8x 8GB, 8x 16GB
