SeedVR2 7B
FlashVSR v1.1 Tiny
Selected from existing metadata; review audio normalized to the four-second video interval. Human quality review pending.
Upscaling comparison
Matched source clips, output sizes and frame counts. Compare text, edges and motion before choosing a model.
Unreviewed sample
Each comparison uses the same four-second source excerpt. All model outputs are encoded the same way for browser review. Play controls synchronize the three videos; only the original audio can be enabled.
Production choice: SeedVR2 · GPU model cache. The FlashVSR sample uses the official locality-constrained sparse-attention backend. Its padding is removed without cropping original content.

Timing and reproducibility details
Processing time includes input preparation, model execution and the model's output encoding. Browser-review encoding is excluded. SeedVR2's first cached request includes startup; subsequent requests reuse the process. FlashVSR model initialization is reported separately. These are matched samples on GB200 GPUs, not a full-corpus speed guarantee.
FlashVSR initialization: 20.6 s. Resolution changes and workload mix affect throughput.
