ProRes To Screenforce (SpotDeli)

Create a Screenforce / SpotDeli MXF from ProRes, with optional external audio, MP4 reference, and XML metadata.

ProRes To Screenforce is a delivery recipe for turning a validated ProRes source into a Screenforce / SpotDeli-ready MXF package, with optional XML metadata and an MP4 reference copy. It is designed for controlled commercial and billboard delivery workflows where format compliance, metadata, and final-file validation all matter.

  • Create a Screenforce / SpotDeli MXF deliverable from a ProRes source video.
  • Reuse supported source audio or replace it with approved stereo or stereo-plus-surround audio files.
  • Generate an MP4 reference export alongside the MXF.
  • Write a companion XML metadata file for SpotDeli delivery.
  • Validate the finished MXF before the recipe reports success.
  • Set Screenforce metadata flags such as MULTI_CHANNEL_AUDIO and LOW_LOUDNESS_LEVEL.

The recipe analyzes the selected source video first and reads product, title, version, and date from filenames such as PRODUCT_TITLE_25_version-1_01-05-2026_HD when that pattern is available. Export only continues when the source meets the expected technical requirements: 1920x1080, 25 fps, BT.709-compatible metadata, and a supported audio layout.

Audio Handling

The recipe supports three audio modes:

  • Use source audio from the video when the source contains either one stereo stream or eight mono streams.
  • Replace the MXF audio with one stereo file.
  • Replace the MXF audio with one stereo file plus one 5.1 surround file.

Replacement audio is checked before export. Stereo files must be exactly 2 channels at 48 kHz, surround files must be exactly 6 channels at 48 kHz, durations must match the source video exactly, and loudness must comply with the Screenforce short-form R128 target unless low loudness is explicitly allowed in the recipe settings.

The generated MXF always uses the Screenforce 8-channel layout:

  • Channels 1-2: stereo program audio.
  • Channels 3-8: muted for stereo-only delivery, or discrete surround channels for multi-channel delivery.

After MXF creation, the recipe analyzes the rendered file and determines the MULTI_CHANNEL_AUDIO XML value from the actual output layout.

Output

The MXF export is written as an MPEG-2 XDCAM HD 422 Long GOP 50 file with 8 mono PCM audio channels at 48 kHz / 24-bit. The recipe can also create:

  • An H.264 MP4 reference with joined stereo audio from channels 1-2.
  • An XML file with product, title, version, date, timecode, length, aspect ratio, advertiser, agency, production company, project, email, comments, HD, MULTI_CHANNEL_AUDIO, and LOW_LOUDNESS_LEVEL.

Output filenames follow the Screenforce-style delivery pattern:

product_title_30_version-1_01-05-2026_HD.mxf

The MXF and XML use the same basename.

Settings

Recipe settings control export behavior and advanced validation options.

  • Export Folder: source folder or custom folder
  • Custom export folder
  • Overwrite existing files
  • Allow low loudness

Allow low loudness is off by default. When enabled, the recipe allows intentionally low-level content during loudness validation and writes LOW_LOUDNESS_LEVEL as TRUE when XML metadata is generated.

During export, the recipe validates the generated MXF again with ffprobe, ffmpeg, and internal delivery checks for container, operational pattern, video format, GOP structure, audio layout, loudness, timecode continuity, aspect handling, and legal color range. This makes it suitable for high-confidence Screenforce / SpotDeli delivery workflows where failed checks should block the handoff.
