What happens inside one AI-made episode: units, redos, versions and the cut

Google Flow and StoryShort, episode by episode

Google Flow and StoryShort read differently on five of the six behaviours: unit, redo charge, versions, transitions and replace in cut. They read the same on one-unit redo. From 4 source pages, read 2026-09-25 to 2026-10-25; no maker pays to be listed.

Inclusion rule. The six behaviours every editor is read on. Order. Register order of the behaviours.

1How the two differ

Google Flow refunds failed generations, keeps every version in History and builds transitions from frames. StoryShort charges for the clips that are made and lets one scene be redone after rendering, but is silent on versions and joins.

How an episode is built

Arrange multiple clips in a sequence. Rearrange the order of your clips.

Google Flow Help, edit your video clips

30 seconds, 1, 2 or 3 minutes. Most micro drama episodes run one to two minutes.

Whether a redo is charged again

You are not charged any credits for failed generations.

Google Flow Help, AI credits

You pay for the clips that are made, so the final cost can be lower.

How many versions are kept

In the History panel, you can find all previous versions of the video and the prompts you used to generate them.

Who controls transitions

You can create transitions, animate images, or generate a video that starts and ends with specific images with the use of frames.

Whether a finished cut can be partly replaced

If you want to add a previous version of an edited video to Scenebuilder, save that version to your project.

Not happy with a shot? Change what happens in it and make that scene again. The rest of the episode stays as it is.
