I was responsible for highlights for many years until the end of 2020/21, the ones below were from the same camera that is still used today (the one that you recommend ahead of the Covid season) and I recorded and edited in 4k.
The quality is night and day to what they are producing now, the only reason I can presume is that they are editing from a copy of the live stream rather than by taking a recording directly from the camera - presumably to save time as replays will already be made for them.
Personally I would rather they spent an extra hour editing to get that quality or the quality @LeodhasXD produces for Alloa now as they are miles ahead of ours.
I did get my hopes up when I saw “high quality highlights” mentioned but sadly no change.
