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.

Yes. Estimated with 32GB RAM + fast-disk: 1152×640·15s at ~1.4 h per clip. Configs that exceed VRAM fall back to weight offloading (slower, but they still render).
About 1.4 h per 1152×640·15s clip (including model load and encoding). Longer or denser clips scale quadratically in the attention term.
At least 32GB of system RAM recommended (minimum 16GB plus a 48GB pagefile). With 32GB, always enable --fast-disk or weights spill into the pagefile.
Stack step distillation (e.g. LightX2V Turbo 8-step v1.0), enable SageAttention / Kitchen attention; for long clips try SLA / VSA sparse attention. All of it is switchable in step 2 of the calculator.
