Choose the audience question before accepting a convenient comparison score.
What you will leave with: A comparison brief that preserves the source sequence references and gives each proposed caption its own evidence requirement.
Use this when
- Two demonstration edits are being considered for a side-by-side campaign presentation.
- A technical comparison is offered as support for a performance caption.
No recording, pose extraction, tslearn or retiming execution.
Name what the side-by-side scene should communicate
A fictional product video shows two demonstrations of a folding mechanism. The producer wants to place them beside one another so viewers can compare the order of the visible stages. A proposed caption goes further and says that the demonstrations proceed at the same pace. The editor receives a favorable technical comparison and is asked to treat it as support for both purposes.
Split those purposes in the review brief. A stage-order explanation can help a viewer understand what happens next. A performance statement makes a different promise about the demonstration. Write the actual proposed caption, not a loose description such as “comparison text,” so the responsible owner can see which words need support.
Keep the source references for each demonstration and identify any existing edits. The producer should know whether the supplied material is a continuous view, a selected excerpt or an illustrative reconstruction. Do not infer that a polished split-screen preview preserves the relationship between the original events merely because both panels arrive at an attractive final image.
Inspect the path as well as the score
Synthetic unitless features x = (0, 1, 1, 2), y = (0, 1, 2) have timestamps (0, 1, 2, 3) and (0, 1, 2) seconds: equal sampling intervals, observed spans 3 and 2 seconds. Use zero-based indices, endpoints (0, 0) to (3, 2), moves (1, 0), (0, 1), (1, 1). Local cost Lij = (xi − yj)². Minimize the square root of total path cost. Rows follow x indices; columns follow y indices. Local matrix rows: (0, 1, 4); (1, 0, 1); (1, 0, 1); (4, 1, 0). Initialize C00 = L00; elsewhere add Lij to the minimum valid predecessor C. Accumulated rows: (0, 1, 5); (1, 0, 1); (2, 0, 1); (6, 1, 0). Path (0, 0), (1, 1), (2, 1), (3, 2) costs 0 despite unequal spans. This is not equal-pace evidence.
The numbers are invented for teaching, not extracted from either demonstration. Attach the complete exhibit to the internal comparison brief rather than replacing it with a badge reading “match.” A badge would conceal the construction that the reviewer needs to understand. Keep the mathematical example visibly separate from any photograph or still taken from the fictional production scenario.
Ask the implementation owner which quantity the actual comparison reports and which inputs it receives. The title of a button is not a description of those inputs. If the owner cannot supply the relevant specification, leave the technical interpretation unresolved rather than copying the teaching example’s explanation into a real project record.
Choose the editorial comparison that is actually supported
Retain stage labels; remove the same-pace caption. This is a choice about what the scene tells the audience, not an instruction to accelerate or slow either demonstration. The editor can use neutral stage labels that explain the visible sequence without adding a comparative performance claim.
Plan those labels around the communication task. For example, the viewer may need to distinguish opening, folding and closure. Have the content owner verify the appropriate names for the product rather than treating the invented feature values as stage names. A technical identifier should not quietly become a customer-facing description of how the product works.
Preserve enough context to show what the operator does before and after the featured action. A tightly cropped shot may make the mechanism easy to see while concealing preparation or an intervening adjustment. If that context changes the meaning of the explanation, include it or choose a different composition. The desired simplicity of the split screen does not justify an incomplete account.
If the campaign genuinely needs the performance statement, make that a separate evidence request. Name the compared task, source recordings and proposed wording. The owner must decide what a valid comparison requires before a new claim is placed into the edit. Do not fill the gap with a statement that the software found a match; that would substitute a tool’s output for the audience question.
Hand over the selected scene without silently expanding its claim
The handoff should contain the proposed split-screen purpose, the approved stage labels, the source references and the exact caption that was removed. Explain why the caption remains outside the selected treatment. That record helps another editor avoid restoring it later because it sounds concise or because a sales slide uses similar wording.
Review the surrounding voiceover and title card as well as the caption. Removing a sentence from one location does not resolve the issue if the narrator makes the same unsupported comparison. Keep the image and language working together: the scene should explain the intended stages without inviting a stronger conclusion through a confident headline.
When a shorter campaign version is requested, preserve the distinction in its brief. A cutdown may lose the setup that made the original comparison understandable. Choose which explanation it can still carry rather than assuming that any excerpt inherits the full scene’s meaning. Record a changed creative purpose openly if the shorter format cannot support the original one.
Close the exercise with a concrete editorial decision: use the two demonstrations to explain the chosen sequence, keep the source references intact and leave the stronger caption unapproved. The calculation remains an internal illustration. No recording has been examined or changed, and no tool has certified the final campaign presentation.
Make the reasoning concrete.
A fictional producer wants a split-screen demonstration and a performance caption, but the supplied comparison has not established the caption’s promise.
Use the favorable score as the caption’s support
Opening: Present the proposed claim beside the demonstration.
Hypothesis: The scene has a concise commercial message.
Risk: The words promise more than the supplied evidence establishes.
Keep the explanatory treatment
Opening: Use verified stage labels and remove the unsupported performance caption.
Hypothesis: The scene can explain the product without inventing a comparison result.
Risk: A desired stronger claim needs a separate evidence request.
Choose the explanatory treatment and preserve the rejected wording in the review brief.

Audience question
What should the side-by-side scene explain?
Proposed wording
Which exact caption makes the stronger promise?
Sources
Which original references and prior edits belong to each panel?
Treatment
Which stage labels and surrounding context remain in the chosen scene?
Handoff
What must the next editor retain when making a cutdown?
Watch for the wrong conclusion.
- Letting a software badge stand in for a defined comparison.
- Removing a disputed caption while retaining the same claim in voiceover.
- Allowing a cutdown to inherit a conclusion after its explaining context disappears.
Your next action
Write the explanatory scene brief and the stronger caption as separate requests, then identify which one the available evidence can support.
