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.
