It adds film grain back into films compressed using Versatile Video Coding (VVC), which often removes the original grain from cinematic footage
InterDigital used IBC to demonstrate how film grain can be added back into cinematic content compressed with Versatile Video Coding (VVC, also known as H.266) for streaming.
The compression process typically removes film grain, which, while making the image cleaner, reduces its appeal to many viewers. InterDigital has set about creating the means to recognise and preserve the original grain, so it can be added back in again after footage has been compressed.
Film grain is a powerful cinematic tool that conveys texture and authenticity in storytelling. However, preserving film grain detail during compression and streaming poses a significant challenge, explains InterDigital.
VVC provides a 50% bitrate reduction compared to HEVC while maintaining equivalent perceptual quality, and is well-suited to high-resolution formats such as 4K, 8K, 360 degree, and 3D content.
By pairing VVC’s efficiency with advanced film grain preservation, InterDigital provides cinema-quality authenticity for seamless, bandwidth-efficient streaming.
