Two individually approved shots can produce an unexpected-looking overlap. A dissolve may seem to darken in the middle, change the relationship between bright areas or create an unattractive colour fringe where shapes meet. Before altering both grades, ask the finishing team how the blend is being calculated.
This is not a question about what a dissolve means in the story. Assume the transition, its duration and the two shots have already been chosen. The task is to make that agreed overlap behave as intended through the colour pipeline.
Separate the endpoints from the overlap
Review the outgoing shot before the transition begins and the incoming shot after it ends. If those endpoints are already wrong, the team has a broader grading or interpretation issue. If they remain correct, focus the comparison on the blended frames.
For a construction case study, a dissolve between a bright exterior and a finished interior may be deliberately gentle. The buyer can describe a specific concern such as a brief darkening that distracts from the intended change of scene. That observation is more useful than asking for both shots to be made brighter.
Keep a reference to the approved endpoints so any proposed correction can be checked against them.
Ask which blending operation is in use
Adobe distinguishes linearising a working colour space from enabling linear blending between layers. Its guidance notes that the latter affects opacity fades and other blend-dependent operations. It also cautions against changing the overall working-space setup late without considering the consequences. See Adobe’s colour-management guidance.
The buyer does not need to prescribe a gamma value. Ask the finisher whether the current calculation is appropriate and whether a controlled alternative would help explain the visible issue. Linear-light processing is a technical option with consequences, not a universal instruction to change every approved project.
Compare the same transition under controlled conditions
Request a short comparison that preserves the shots, grades, transition length and timing. Change only the relevant blend treatment where the application allows that test. Include enough clean picture on either side to judge the relationship to the endpoints.
Watch the entire transition at normal speed before examining individual frames. A midpoint still can explain why an overlap looks different, but the acceptance question is how the passage moves from one scene to the next.
Check bright details, saturated edges and the overall impression of brightness. If the alternative improves one feature while changing another, discuss that trade-off explicitly. The desired result may be a deliberately shaped transition rather than a mathematically uniform blend.
Limit the correction to its intended scope
Ask whether the chosen change affects only this transition, its containing composition or the whole project. A global setting should not be altered merely to solve one local overlap without reviewing its wider effect.
Once the preferred treatment is established, compare other blend-dependent elements within the affected scope. This is especially useful if the same setting also influences layered graphics or motion blur.
Accept the final exported passage with its endpoints intact and its middle behaving as intended. Record the processing choice so a later conform or render does not quietly substitute a different calculation.
