The canvas agent now writes video prompts as flowing prose

When you ask the canvas agent to write a Seedance prompt, its output looks different now.

  • Bracketed blocks: [GLOBAL] [SCENE] [CAMERA], filled in slot by slot
  • Flowing prose: one continuous passage that still carries everything those slots used to

Why prose holds up better

Filling slots slides very easily into adjectives — drop one word per slot and it looks finished. But adjectives don't produce pixels:

  • "tense atmosphere" doesn't make the shot tense
  • "a magenta light" can come back orange-red — the model slides toward whatever prior sits closest

Prose forces you to finish the sentence. Same lighting example, written as three things: where the light comes from, what it lands on, and what the skin looks like once it does. Write all three and the colour holds.

What you need to do

Nothing. It's already live.

The old format is still there

The bracketed template hasn't been deleted — it's kept as a compatibility format.
