David Sandberg has responded and said “This was an internal promo video that was never supposed to be seen by the public. I feel bad because it contains a bunch of plot points and temp VFX,” Sandberg told Variety in a statement. “I hope at least people can see the passion that we poured into the movie, the world deserves to see it as it was meant to be seen. This movie has been held hostage for the past 5 years but I promise to keep fighting for it and make sure this film gets the chance it truly deserves.”
Immersive video offers a 6-Dof-free viewing experience, potentially playing a key role in future video technology. Recently, 4D Gaussian Splatting has gained attention as an effective approach for immersive video due to its high rendering efficiency and quality, though maintaining quality with manageable storage remains challenging. To address this, we introduce GIFStream, a novel 4D Gaussian representation using a canonical space and a deformation field enhanced with time-dependent feature streams. These feature streams enable complex motion modeling and allow efficient compression by leveraging their motion-awareness and temporal correspondence. Additionally, we incorporate both temporal and spatial compression networks for endto-end compression.
Experimental results show that GIFStream delivers high-quality immersive video at 30 Mbps, with real-time rendering and fast decoding on an RTX 4090.
