I see many of you creating long WAN 2.2 videos (several minutes) without frame degradation, darkening, or looping. My results degrade when generating segment-by-segment.

Could you share how you maintain stable quality in long videos?

Specifically:

Do you use continuous generation or segmented workflow?

How do you avoid brightness drift / artifact accumulation?

How do you prevent motion loops?

Do you reuse keyframes or reference images between segments?

Any recommended settings (noise, denoise, seeds, prompts)?

I’d really appreciate any tips on achieving long, stable WAN 2.2 videos. Thanks!
