Remarks

Each video mode represents a complete broadcast standard definition including resolution, frame rate, scan type (progressive/interlaced), and timing parameters. These modes conform to international broadcast standards defined by organizations like SMPTE, ITU-R, and EBU.

The numeric values are FourCC codes used internally by the Decklink SDK for mode identification. These values should not be modified as they correspond to specific hardware implementations.

Common broadcast workflows by region and application:

  • North America (NTSC regions): 1080i59.94, 720p59.94, NTSC
  • Europe/Asia (PAL regions): 1080i50, 720p50, PAL
  • Cinema/Film: 1080p23.98, 1080p24, 2K/4K DCI modes
  • Live production: 1080i59.94/50, 720p59.94/50
  • Streaming/OTT: 1080p29.97/30, 1080p59.94/60
  • UHD/4K production: 2160p23.98-60 modes

Frame rate notation: - Fractional rates (23.98, 29.97, 59.94) are used for NTSC compatibility - Integer rates (24, 25, 30, 50, 60) are used for film and PAL regions - "Pulldown" modes apply 3:2 pulldown for 24fps film to video conversion
