Standard LightX2V workflows run 4 steps per stage. These LoRAs are tuned so you can run 2 steps per stage and still get usable motion and prompt follow at roughly half the 4Step time.

The time we spend on a 512×848 clip with 4Step LightX2V is about what it needs for 720×1280 with this pair.
Best when you need many previews, prompt tests, or seed hunting, and care more about iteration speed than maximum fine detail.
euler + simple still works, but reliability drops. Expect more duds, often about 2 good out of 4 runs. Prefer the samplers above when you want fewer re-rolls.
Quality expectations
From a small random-seed test set (9 generations):
Outcome
Count
Notes
Clean motion, on-prompt, no body deformation
6 / 9
Usable “hero” candidates
Mild motion issues
1 / 9
Often still salvageable
Strong motion error
2 / 9
Reroll seed
So: most seeds are fine, a minority will need a new seed. That trade-off is kinda acceptable for speed.
Compared with full 4-step LightX2V you may lose some fine detail and consistency. For final hero frames, you can still switch back to a 4-step stack.
