Style bleed

A style applies unevenly — leaking into regions it should not touch, or resolving differently in adjacent shots that were supposed to match.

Also called

  • Style inconsistency
  • Look drift
  • Conditioning leak
Evidence

The look is nominally the same throughout. Sample any two moments and they disagree about what the style is.

Causes
  1. 01Style conditioning applied globally, so it affects regions that should have been left alone — skin, text, product detail.
  2. 02Each segment conditioned independently, resolving to a different point on the same style manifold. Every shot is correct; the sequence is not.
  3. 03Style weight high enough to override content, so the look starts rewriting what is actually in frame.
  4. 04Prompt terms that describe style and subject in competition, letting the sampler decide which wins.
  5. 05Reference imagery that is internally inconsistent, so "the style" is really an average of several styles.
What actually helps
  1. 01Anchor every segment to the same shared reference rather than letting each derive the look independently.
  2. 02Lower style weight and recover intent later in the chain, where it can be applied precisely.
  3. 03Use regional conditioning or masks so the style stops applying where it should not.
  4. 04Separate luminance intent from colour intent — most bleed is the two fighting over the same channel.
  5. 05Audit reference sets for internal consistency before blaming the model.

Tends to originate at

  • Global style conditioning without spatial control
  • Independent per-segment conditioning
  • Competing prompt terms

How to confirm it

Pull stills from several points in the sequence and put them side by side out of order. If you cannot tell they came from one style, that is bleed.

The out-of-order part matters. Viewed in sequence, gradual variation reads as intentional — the eye forgives a slow shift. Shuffled, the inconsistency is immediate.

The distinction worth keeping

Style bleed and temporal flicker are often lumped together as “inconsistency”, but they have different mechanisms and different fixes.

Flicker is high-frequency — instability between adjacent frames. Bleed is low-frequency — variation across a sequence or between shots. A fix aimed at one will usually do nothing for the other, which is why “make it more consistent” is not an actionable note and diagnosing which of the two you have is the first useful step.
