The spec sheets as one file
Both sides of every comparison on this site are exported together: what a placement requires and what a generator emits, in one file with sources attached. As of 2026-09-12.
A media plan and a production plan are usually built in different tools by different people. A single file that holds both sides of the constraint is the cheapest way to stop them disagreeing about what is possible.
Platform specs change without announcement, which is why the reading date matters more here than in most registers. A figure in a brief that was right in March can be wrong by the time the campaign books.
Rows that record an absence are exported too. A platform that publishes no hard ceiling, or a generator that publishes no maximum clip length, is a scheduling risk rather than a generous one, and the file says so.
The licence below permits commercial reuse with attribution, which is the normal case here: these numbers are most useful inside an agency's own planning sheet.
1What each column holds
| Column | What it holds |
|---|---|
| fact_id | The row's fixed reference. A corrected spec keeps it. |
| value | The requirement in the platform's own numbers and units. |
| applies_to | The placement or tool the requirement governs. |
| source_url | The help page the requirement came from. |
| source_name | That page's own heading. |
| value_since | When the requirement is first known to have applied. |
| verified | The last time the help page was checked. |
Inclusion rule. Everything on the sheets is exported, including rows that record a missing published limit. Order. File order follows recording order, grouping placement rows and tool rows separately.
The file is at /datasets/specs.csv, licensed CC BY 4.0. Attribution should name the sheets and the reading date.
Elsewhere in the kit: Placements, Tools, Axes, Pairs, Questions, Terms, Learn. How a spec gets onto a sheet is set out on the method page.
2Making the ad itself
For ad work around “Data”, SceneMixer's pages explain how its ad projects are produced:
A short drama episode has two jobs: stop the scroll in its first seconds, and make the next episode feel necessary in its last.

You can recomposite with different end-card text, and in step-by-step mode you can reshoot individual segments. The finished file can also be downloaded and shared with a link.
