Times are per whole clip (model load and text encoding included); the first run is slower due to kernel compilation. ⚠ = weight offloading / noticeably slower; ✕ = not recommended.
--fast-disk768p 5s; 4-8 steps; 1-5 min per clip
Yes. Estimated with 32GB RAM + fast-disk: 1920×1088·15s at ~42 min 35 s per clip. Configs that exceed VRAM fall back to weight offloading (slower, but they still render).
About 42 min 35 s per 1920×1088·15s clip (including model load and encoding). Longer or denser clips scale quadratically in the attention term.
At least 64GB of system RAM recommended (minimum 32GB plus a 16GB pagefile). With 32GB, always enable --fast-disk or weights spill into the pagefile.
Stack step distillation (e.g. LightX2V Turbo 4-step v1.1 768p), enable SageAttention / Kitchen attention; for long clips try SLA / VSA sparse attention. All of it is switchable in step 2 of the calculator.
