# Swiss QC Guru

> Swiss QC Guru by NuNu Soft is a desktop app for Windows and Mac that checks a finished transmission master against the delivery specs of ARD, ZDF, ORF and SRF (EBU R 103, EBU R 128) before it is delivered. Every finding has a timecode, a frame and the line of the spec it breaks. One-time price: USD 199. Free trial: checks the whole file and shows half of the findings. Current version: 0.2.1 (6 November 2026).

- Add-ons in preparation: UK DPP / AS-11, German private broadcasters, ARTE and France Télévisions, SRG SSR, online and podcast platforms, more looks for the client view
- Checks (23): container and metadata (MXF OP1a, header Closed and Complete, codec, bit rate, colour tag 1-1-1, track layout, start timecode), levels and gamut (luma, RGB, chroma per frame, small areas separately, illegal codes, TRS), loudness and audio (integrated loudness, true peak, LRA per track pair, clipping, phase, silence, missing audio, Dolby E), black, freeze frames, repeated frames and cadence, interlace against flag and format, bars and borders, pixel defects, banding, a hint on possible flashes (not a certified Harding test), timecode continuity, burnt-in timecode against container timecode, colour bars and line-up tone

- Thresholds carry their source in the spec; where a spec does not state a value it is marked "unconfirmed"
