Keeping characters' faces the same across episodes

The fastest way to ruin a multi-episode video is a character with a different face in every episode. aigens solves this with the project's character library: each character has one reference image that you approved, and every episode using that character takes exactly that image.

One key, one look

Each character has a key, for example ong_tu. A key belongs to exactly one look. If the same person wears a completely different outfit, create a new key, for example ong_tu_ao_dai, instead of editing the old key's description.

Writing descriptions for stable images

• Give at least two facial features: beard, hair, skin tone, age.
• Describe one specific outfit, with colors.
• Add one signature item: a conical hat, a necklace, an apron.
• Avoid describing actions. Actions belong in the scene prompt.

When you edit a description, the current image is marked as outdated. Once you regenerate and approve it, episodes that haven't rendered pick up the new image automatically; episodes already rendered keep the old image until you decide to redo them.
