Screenforce (SpotDeli) Checker

Analyze a media file and run Screenforce (SpotDeli) delivery checks.

Screenforce Checker is a dedicated QC recipe for validating MXF files against the Screenforce / SpotDeli delivery checklist inside Magnetron. Instead of only showing generic probe data, it breaks the file down into concrete pass/fail checks that matter during handoff.

  • Analyze a selected MXF file and show a checklist of delivery checks.
  • Validate container, operational pattern, raster, frame structure, bitrate, timecode, audio layout, loudness, and legal color behavior.
  • Summarize the result directly in the UI so you can quickly see whether the file is delivery-ready.
  • Use it as a QC checkpoint before sending a file onward or before investigating why an export failed spec.

The checker combines ffprobe, ffmpeg, and Magnetron's own analysis helpers to inspect both file metadata and signal behavior. That means it does more than confirm that the file merely opens: it also checks whether the structure, audio arrangement, loudness, timecode, and signal rules line up with the Screenforce MXF profile.

Current Check Areas

  • File readability and MXF container detection
  • OP1a operational pattern
  • MPEG-2 XDCAM HD 422 Long GOP 50 video profile
  • GOP size, bitrate, raster, HD 1080i25 / 1080i50 structure, and field order
  • Timecode start and GOP timecode continuity
  • Aspect ratio and letterbox behavior
  • BT.709 metadata and illegal color checks
  • Duration multiple-of-5 validation for commercial-style delivery
  • 8-channel mono PCM audio structure at 48 kHz / 24-bit
  • Stereo-only and stereo-plus-surround channel layout validation
  • Stereo and surround loudness checks against the Screenforce short-form R128 profile

That makes Screenforce Checker a practical preflight recipe when you need a fast answer to the real question: not just “does this file play?” but “does this file actually match the Screenforce / SpotDeli delivery we meant to create?”
