Runway and Synthesia on an omission against a sentence
The pair exists to show what the difference in evidence costs. Both entries report a visible mark on some output, and only one of them can be quoted on why, when or how it goes away. As of 2026-09-22.
| Point | Runway | Synthesia |
|---|---|---|
| Source of the position | A phrase absent from the free plan | A page written to answer how to remove it |
| Causes the page names | None | The Basic plan, and API test mode |
| Removal route described | Buy a paid plan | Upgrade, then generate the video again |
Inclusion rule. Two entries whose published answers to one column pull in different directions. Cells hold each vendor's own wording from the page its entry names; pairs that agree on the column are not filed at all. Order. Fixed order, and the two columns are in the order the heading gives them.
1A support page answers questions a plan table cannot
Help-desk prose exists because somebody asked, and it is written by people who will be held to it by the next ticket. That tends to make the scope accurate and the instructions concrete.
A plan table exists to help somebody choose, and it compresses ruthlessly. Absence in a feature grid means not listed, and the reasons for a summary leaving something out have nothing to do with the subject being researched.
2Re-generate is the word that changes a schedule
One of these entries states that fixing a marked file means producing it again. That moves marking from a post-production question to a scheduling and budget question, and on a series the difference is large.
The other entry says nothing about finished files at all. A reader has to assume that buying a plan affects future output and cannot tell from the page whether it affects anything already made.
3Where an inference is honest and where it is not
Recording the omission as an omission is honest. Recording it as a statement that free output is marked would be an invention, and the two look identical once they are in a table.
That is why the strength of evidence is a row on every entry in this section. A reader can discount what deserves discounting without this register doing the discounting on their behalf.
