15.3 Quality Control and Technical Specifications

Quality control and technical specs are crucial in post-production. They ensure your final product meets industry standards and client expectations. From color accuracy to file integrity, these checks catch issues before delivery.

Loudness standards and delivery specs keep your content consistent across platforms. Test patterns and compliance testing verify technical requirements are met. These processes guarantee a polished, professional output ready for distribution.

• Quality Control (QC) is a critical process in post-production that involves thoroughly checking the final output for any issues or errors before delivery
• Color accuracy ensures the colors in the final output match the intended look and feel of the project, maintaining consistency across different displays and platforms
• Sync check verifies the audio and video are properly synchronized throughout the entire project, preventing any lip-sync issues or audio drift
• Common sync issues can arise from incorrect timecode, mismatched frame rates, or errors during the editing process (dropped frames)

Maintaining File Integrity and Detecting Artifacts

• File integrity checks confirm the exported file is not corrupted and plays back correctly on different systems and players
• This process may involve verifying the file size, format, and metadata are correct and match the project specifications
• Artifact detection identifies any visual or auditory glitches, compression artifacts, or encoding errors that may have occurred during the export or transcoding process
• Common artifacts include pixelation, blocking, banding, and audio pops or glitches, which can be caused by incorrect export settings, codec limitations, or hardware issues

Technical Specifications

Adhering to Loudness Standards and Delivery Specs

• Loudness standards, such as EBU R128 or ATSC A/85, ensure the audio levels are consistent and compliant with broadcast and streaming platform requirements
• These standards prevent excessively loud or quiet moments in the audio, providing a more pleasant viewing experience for the audience
• Delivery specs outline the specific technical requirements for the final output, including file format, resolution, bitrate, and codec
• Adhering to delivery specs ensures the final output is compatible with the intended distribution platform and meets the client's expectations (ProRes 422 HQ for broadcast, H.264 for web)

Utilizing Test Patterns and Compliance Testing

• Test patterns, such as color bars and tone, are used to calibrate and verify the accuracy of the video signal and audio levels
• These patterns help ensure the final output will display correctly on different monitors and systems, maintaining consistency across various playback devices
• Compliance testing involves running the final output through a series of automated checks to ensure it meets the required technical specifications and standards
• This process may include checking for proper closed captioning, subtitles, audio channels, and metadata, as well as verifying the file is free of any errors or warnings that could cause playback issues or rejection by the distribution platform
