❓ Issue/Question

• What is a live preset and when should I use one?

👌 Resolution/Answer

• What is a live preset?
  • A live preset is a saved set of encoding and recording settings that you apply to a live ingest when you schedule it, so you don't have to set them again for every fixture
  • A preset holds the video bitrate, resolution, video scan type, frame rate, and, optionally, custom audio channels
  • Resolutions available: 1280 x 720, 1920 x 1080, and portrait 720 x 1280 and 1080 x 1920
  • Scan types: progressive, top field first or bottom field first
  • Frame rates can have decimals, e.g., 29.97 or 59.94
• When do we recommend using one?
  • You need more than the default outputs. Without a preset, only 1080p and 720p proxies are generated
  • The feed is interlaced, portrait, or uses a non-standard frame rate
  • The feed carries several audio tracks (e.g., commentary in different languages, ambient, radio), and you want each one named and kept as its own track
  • You need to combine mono tracks into a stereo or 5.1 track
  • You run several feeds with different setups, e.g., clean and dirty feeds usually need different bitrates and audio mapping
• When you don't need one?
  • A standard 1080p feed with a single audio track works fine without a preset
• Use a preset
  • Go to Live > Live presets and click New preset
    • How to create custom audio channels via live presets? 
  • Select the preset when you schedule the live
    • How do I schedule a live event in ScorePlay? 
• Before the event
  • Make sure the preset matches what the encoder actually sends: the same frame rate and scan type, and no more audio tracks than the feed carries
  • Test with a lineup test before event day

🔖 Notes

• A preset can't be changed on a live that already exists. To use a different preset, delete the live and schedule it again
