• Slate insertion doesn’t work on the encoder.
• While HDR does pass correctly, the encoder’s HDR indicator doesn’t show HDR for some sources, such as Xbox One S/X, PS4 Pro, and DirecTV C61K-700.
• To prevent VQ issues, Kaleidescape Strato should be set to “Use External Scaler” mode and set to 1080p. This prevents menus from rendering in UHD.
• HBR audio formats (Dolby® Atmos®, Dolby TrueHD, DTS®:X, DTS-MA) were temporarily removed from encoder EDIDs
