OpenAPV: Open Collaborative Innovation in Professional Video Ecosystem

摘要

Over the past few decades, significant resources have been invested in developing video codecs for the storage and delivery of video data. International standards development organizations, such as MPEG (Moving Picture Experts Group) and AOM (Alliance for Open Media), have fostered large-scale competitive collaboration among industry players. While open-source software developed alongside these video codec standards has accelerated verification of the standard and enabled rapid adoption, as it is used as a starting point for implementation and future research, this practice has not been fully applied to the ecosystem of mezzanine video codecs used in high-quality video capture and post-production. To address this gap, the industry's first open source project for collaborative innovation in professional video codecs, OpenAPV, has been established. The project aims to facilitate collaborative research and development of a royalty free, open source, and open standard video codec for professional use. This paper outlines the technical aspects of the video codec, together with the open source software implementation. The codec has been successfully tested across various platforms and shows excellent R-D (Rate-Distortion) performance and coding speed, even without hardware acceleration. Furthermore, it demonstrates robust quality resilience against multiple rounds of encoding and decoding cycles, which are common in video post-production.
