Drift is the silent killer of AI video: colors shift, shapes warp over time

A creator working with Pixverse V6 started a Reddit discussion on drift in AI video: after a few seconds, colors shift, edges blur, and objects change shape — worsening the longer the clip runs.
- Current state: Pixverse V6 has improved character/scene consistency but drift persists; official guidance suggests consistent character descriptions and reference images.
- One explanation: models train on clean data but must refer back to their own previous outputs during generation, so early small errors get carried forward and amplified.
- EPFL approach: train on imperfect data so the model learns to recover from errors rather than accumulate them.
- Author's workaround: keep individual clips short and stitch manually — effective but labor-heavy.
The author asks the community for better workflow-level fixes.
