1080p neural video coding on a mobile device
In another world’s first in terms of AI running on device, this CVPR 2023 demo showcases encoding and decoding 1080p videos on a mobile device. Neural codecs are versatile: they can be customized for specific video needs, can be optimized for perceptual quality through advances in generative AI, can be extended to new modalities, and can run on general-purpose AI hardware. However, they present numerous challenges which make them difficult to implement on compute-constrained devices. We designed a novel and efficient neural interframe video compression architecture which makes it possible to do 1080p video coding on device. In the demo, you can see that the rich visual structures and complex motions of the high-quality video are accurately preserved by the neural video codec.
