Understanding Mezzanine Formats
What Are Mezzanine Formats?
In professional video production, mezzanine formats serve as intermediate, high-quality codecs specifically designed to preserve maximum image fidelity during the post-production process. Unlike consumer-level codecs, which typically emphasize smaller file sizes and ease of playback, mezzanine codecs prioritize visual integrity, color accuracy, and editing flexibility. We rely on these formats because they offer an ideal balance between compression and quality, ensuring minimal loss of visual information throughout multiple editing cycles, color grading, compositing, and other post-production tasks.
Mezzanine formats are not intended for final delivery or consumer playback. Rather, they function as intermediate master files, bridging the gap between original camera footage—often captured in RAW or high-bitrate formats—and the final compressed versions ready for distribution. By using mezzanine codecs, we maintain consistency, streamline workflows, and reduce the risk of quality degradation that typically occurs when repeatedly compressing and decompressing video files during editing.
Common Mezzanine Formats: ProRes and DNxHR
Two of the most widely adopted mezzanine formats in the industry today are Apple ProRes and Avid DNxHR. Apple's ProRes codec family has gained immense popularity due to its robust performance, exceptional visual quality, and broad compatibility across editing platforms.
