A brand’s media proposal connects a television spot to product detail on mobile. The creative team starts writing the mobile video as chapter two, assuming that its audience has already encountered chapter one. Before production is approved, someone needs to establish what connects those chapters.
For overseas brands working with Chinese product and production partners, ONCE recommends distinguishing three scopes: distribution across screens, linked audience delivery and ordered exposure. Complementary assets can be valuable at any of those levels. The production brief should match the delivery relationship that can actually be specified and checked.
A new format makes the scope question timely
Convo Media’s official StoryVideo announcement is dated October 30, 2026. It describes pairing television creative with supporting content frames and extending the experience to mobile content. November 3 coverage appeared after that announcement; it is not the original launch date.
This establishes the company’s offering and intended experience. The announcement alone does not settle the identity method, next-exposure trigger, path completion or incremental sales for a particular campaign. That is not a claim that the supplier lacks those capabilities. It is a reason to specify the missing project details before paying for a narrative that depends on them.
ONCE’s three-scope acceptance review
This is a procurement method, not an official platform classification. A more elaborate scope is not automatically a better purchase.
| Scope | What needs to be specified | Creative implication |
|---|---|---|
| Distribution across screens | Actual placements, formats, schedule and delivery reporting for each screen | Each version establishes the product and message independently, with shared identity |
| Linked audience delivery | Whether linkage concerns people, accounts, devices or households; its basis, coverage and reporting | Complementary content retains enough context for a first encounter |
| Ordered exposure | Qualifying events, timing, eligibility, incomplete paths and the available path record | Structure steps around executable rules and account for missing or unfinished steps |
The media owner confirms delivery rules. The production owner confirms which content depends on those rules. The client approves their relationship. A list of files does not replace a media execution description, and a producer should not inherit an unverified sequencing promise merely because the brief says the system will connect everything.
If linkage is modeled or reported at an aggregate level, keep that description intact. Do not retell it as a complete viewing history for every individual.
A sequence has an explicit next-step condition
Google Ads’ current video ad sequencing documentation offers a useful contrast: it defines steps, progression based on impressions, views or skips, and step-level and Sequence path reporting. It also limits that campaign type to YouTube.
Those rules do not establish capabilities for another CTV or mobile channel. Nor is this a recommendation to move every cross-screen campaign to Google. The point is that sequencing can be described as conditions, not simply as numbered creative files.
Ask the proposed media partner to explain the first event, when a later step becomes eligible and whether its records describe plans, qualifying opportunities or actual delivery. Successful configuration is different from completed exposure. Even a qualifying view remains different from comprehension or purchase intent.
Draw the content map separately from the delivery map
The creative map identifies what the TV spot introduces, what the supporting frames add and what mobile content helps a buyer explore. The delivery map identifies who may receive each asset, what links those opportunities and which events or restrictions apply.
Consider a hypothetical air-purifier brand sourcing from China. The television creative establishes a home-use situation; the mobile asset explains filter replacement and compatibility. Under a distribution-only plan, the mobile asset should identify the product and establish its own question. It can still add depth without replaying the entire TV commercial.
Under an agreed linkage method, do not open with “now that you understand.” The linkage is a delivery basis, not a knowledge assessment. A recognizable product and a brief demonstration can reconnect the idea before introducing the detail.
Where an executable sequence has been confirmed, decide which repetition can be reduced and what to do about skipped or incomplete paths. Let those requirements determine whether another opening or shoot is needed, rather than buying additional “chapters” first.
Two delivery totals do not describe a connected path
CTV impressions and mobile impressions describe their respective delivery under their reporting definitions. Without an appropriate linkage method, they cannot be assembled into a count of people who continued across screens. Adding the totals also does not create deduplicated reach.
For a linked or ordered scope, agree the reporting unit, fields, observation window and uncovered portion. Where privacy or system constraints prevent individual records, select an appropriate aggregate way to support the agreed claim, or reduce its granularity. Procurement does not require seeking personal data that the project does not need.
Start by checking that the approved assets match the execution rules. A claim about incremental sales would require a separate comparison designed to address other changes. A coherent path illustration or a completed report cannot supply that comparison by itself.
Separate the outputs in the quotation
Production covers the main film, supporting graphics, mobile content and any alternate openings. Media execution covers placements, linkage or sequence configuration and operation. Measurement covers the available reporting and its interpretation. One partner may coordinate all three, but the outputs should remain identifiable.
For recurring creative services, preserve the conditions under which each version works: independent explanation, complementary detail or a particular preceding event. That record may support reuse in later campaigns. Any savings or performance gain must be established from actual work, rather than assumed from the size of the asset library.
ONCE’s video marketing collection explores related distribution decisions; its production collection covers the work required to deliver suitable versions.
Before approving the next cross-screen package, identify its scope in the three-row review. Then decide whether mobile content can depend on a prior chapter. If the delivery connection has not been established, commission useful complementary assets first.
