I've installed Ventura 13.5 on my cMP 5,1 using Open Core Legacy Patcher 0.6.8. Things are working well except for the videos I took with my iPhone 12 Mini. In Photos, they'll play, but there's an exclamation triangle in the upper left corner. When I click on it, it shows an error dialog that states: "Unsupported Video Format". There are two other symptoms:

  1. The edit button is disabled
  2. The poster frames are all washed out
I have a Radeon RX 580 graphics card. Has anyone else run into this? Is it expected?
