Synthesia and Wan on what changing course actually costs

Both entries describe a way to get an unmarked file, and the difference is what it costs. One asks for a purchase and a re-render; the other asks for one field in the next call. From 2 source pages, read 2026-09-22; no maker pays to be listed.

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.

1Neither route repairs a file that exists

Both arrangements are about what the next render carries. A finished asset stays as it is in both cases, which is easy to miss because one of the pages frames its route as removing the watermark.

Reading the instruction carefully, the removal happens by producing the video again. On a generated asset that is not a repair: a re-render is not guaranteed to match an approved cut.

2A free lever and an expensive one, on the same layer

Setting a field costs nothing and can be done per clip. Upgrading and re-rendering costs money and time and has to be scheduled, and on a season of episodes it has to be scheduled repeatedly.

That asymmetry has nothing to do with the clause and everything to do with when a production makes its decision. Deciding late is cheap on one of these tools and expensive on the other.

3One page also states what no upgrade reaches

The same support article records that a mark applied in test mode cannot be taken off a finished video. So one of this pair has a documented case where the removal route does not apply at all.

The other entry has no equivalent, because its flag was never applied without somebody asking. Nothing there can be applied by accident, which removes the whole category of problem.

4A provider's own account

Against the duty in “Synthesia and Wan”, SceneMixer's published pages describe what its pipeline produces:

Dubbing replaces the audio of a finished clip; the picture was generated for a different line, so mouth shapes, pauses and shot length all belong to the original language. Native-language generation gives the video model the line in the target language before it renders the shot, so the performance, the pacing and the cut points are built for that language.

The base image is the sword as carried; drawn is a separate state image, selected for the segments where it applies. Drawing both configurations in one picture used to make the render snap the blade back into its scabbard mid-shot.
