Single 2D video to 4DGS: a 4-second scene took 69 minutes on RTX 6000 Ada

The author rebuilt a 4D Gaussian Splatting scene from a single 2D video (4 seconds, 121 frames) using the 4DAnyone → 4D-GS pipeline, taking 69 minutes on an RTX 6000 Ada. For reference, a single-frame 3DGS run with @lichtfeldstudio reached 30K iterations in 13 minutes with visibly higher quality.
Key takeaways:
- The 4DGS pipeline used is two years old and likely the main quality bottleneck
- High-resolution long-video 4DGS on workstation hardware remains impractical
- Getting 4D output from one video is impressive, but quality and speed are still far from production-ready
