Generations, Thumbnails, and History
Understand the difference between a generation and a thumbnail, how to browse your history, and what you can do with each output.
Generations vs Thumbnails
A generation is a single run of the AI — one submit, up to 4 variations produced. Each variation within a generation is a distinct image candidate.
A thumbnail is a variation you have promoted or attached to a video. Thumbnails are the "chosen" outputs; generations are the raw candidates.
Browsing the gallery
The Generations section in the sidebar shows your full history. Each card represents one generation run, with its variations displayed as a grid. The most recent generations appear at the top.
The Thumbnails section shows only promoted outputs, making it easier to find your best work without scrolling through failed experiments.
The thumbnail detail view
Click on any variation (in the gallery or in the editor results) to open the detail lightbox. From there:
- Download — save the 1280×720 PNG to your device.
- Reuse — instantly re-run this exact generation again (same prompt, settings, references, and lane) to get a fresh batch of variations.
- Edit — open the Modify dialog to change this thumbnail (adjust the prompt, swap a Person or reference, tweak the model) and generate a new version.
- Fork to Inspiration — add this thumbnail to your Inspirations library so you can use its style in future generations.
- Add to Video — attach this thumbnail to a video project in your Video Manager.
- Copy — copy the image to your clipboard.
Version history and starring
Every variation is auto-saved. You can Star a variation to mark it as your preferred candidate for a given concept. Stars make it easy to distinguish the keepers from the discards when you have many generations for the same video.
Reuse vs Edit
Two actions cover the two things you usually want:
- Reuse re-runs the exact same generation again — same prompt, settings, and references — to get another batch of variations. Nothing changes; you just roll again.
- Edit (the pencil) opens the Modify dialog, the real iteration path: adjust the prompt, swap a Person, add a reference, or change the model, then generate.
Either way, each run creates a separate generation entry in history — the original is never overwritten.
Attaching to a Video
The Add to Video action links a thumbnail variation to a Video project (see the Video Manager). This lets you track which thumbnail you used for each video and revisit the generation that produced it.
