This document serves to outline the technical equipment requirements for a QC Room working on Netflix Branded Content via Asset QC.
Requirements for all types of QC
- A Unity Environment
- In order to properly perform QC, all audio and video must be reviewed on equipment that neither adds nor reduces Audio or Video information to the program stream.
- Room Isolation
- Outside light and sound should not come into the QC room
- Don’t situate your QC room near high traffic hallways, walls facing the street, or rooms with windows that cannot be easily blacked out.
- Rooms should have sound proofing or sound baffling to reduce noise bleed.
- Monitor should be able to play back at least UHD resolution and be Dolby Vision/HDR capable
- Monitor should be regularly calibrated for use in P3 or REC 709 colorimetry
- We recommend either a professional grading monitor or a high end prosumer Dolby Vision TV
- Ex. Sony X310, LG C9, Panasonic EZ1000, Sony Master Series
- Speaker should be in at least a 5.1 surround environment, Stereo can be QC’d in headphones
- If QCing Atmos, then speaker arrangement should be at least 7.1.2
- Speakers should be regularly calibrated and set to 72dB spl
- No EQ should be applied to sound
- In order to properly perform QC a unity environment in the QC space needs to be maintained. What this means is that all audio and video must be reviewed on equipment that neither adds nor reduces Audio or Video information to the program stream.
- In Audio QC, added EQ balancing could accentuate or obscure audio issues that we want to be flagged. All EQ curves for QC review should be flat and the signal path through should be at reference. Don’t put any presets on your receiver if you have one connected to your Chromecast.
- In Video QC, monitors should not be adding motion smoothing or color information to the picture.
- Enough room for the operator to sit with the monitor in full field of view and within the span of each surround speaker
