Spot MXF Checker - Magnetron

Spot MXF Checker is a dedicated QC recipe for validating MXF files against a SPOT-style 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 see quickly 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, and signal rules line up with the intended SPOT MXF profile.

Current Check Areas

File readability and MXF container detection
OP1a operational pattern
XDCAM HD 422 Long GOP 50 video profile
GOP size, bitrate, raster, HD 1080i50, and field order
Timecode start and continuity
Aspect and letterbox behavior
BT.709 metadata and illegal color checks
Duration multiple-of-5 validation
8-channel mono PCM audio structure at 48 kHz / 24-bit
Stereo and surround loudness checks for the expected channel groups

That makes Spot MXF 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 look like the delivery we meant to create?"
