Film grain is crucial to the artistic visio n of video sequences but poses a significant challenge for video encoders\ , often requiring either high bitrates to preserve the grain or its remova l to achieve lower bitrates. Film grain synthesis (FGS) addresses this by recreating grain during decoding\, allowing for efficient delivery of near -grain-free video while preserving artistic intent. The prevalent technolo gy\, AFGS1\, is integrated into AV1 decoders and has been extended to HEVC decoders\, with potential future applications in VVC. Despite its benefit s\, deploying FGS involves challenges\, including the need for simulcastin g to support legacy devices\, which can increase CPU usage and data traffi c. This paper examines practical deployment aspects of FGS for both file a nd live delivery\, focusing on optimizing delivery for mixed environments of legacy and FGS-enabled clients. It evaluates the impact of various “deg raining” levels\, encoding methods\, and distribution strategies on percei ved quality\, resources\, and data traffic\, aiming to provide guidance fo r effectively integrating FGS into existing systems.
