There's a programme on the bbc iplayer around 60 minutes long. It shows filmed footage of a Scottish Appeals court, as it examines three cases. The first two are murder charges, the third drugs related.
The murder case appeals: Nicholas Rogers (sentenced May 2018) Blackkalendar.nl/c/35015/Nicholas%20Rodgers
Robbie Brown; Lee Noonan; Paul Green (all February 2018) Blackkalendar.nl/c/35637/Robbie%20Brown
Interesting and worth a look if you like the legal stuff.
