THE DEPTH MAP TRICK THAT ALSO WORKS ON EXPRESSION, NOT JUST DANCE — GPT IMAGE 2 × SEEDANCE 2.0 Feed the model raw footage of someone gesturing, reacting, moving through a scene, and it tries to interpret everything at once - the face, the outfit, the alley, the light, and somewhere in there, the actual motion. Feed it a depth map instead and there's nothing left to read but the movement itself. Most creators assume this trick only applies to dance, where the motion is clean and repetitive. It works just as well on loose, expressive, conversational movement - the kind with no fixed rhythm to lean on. The problem was never the model's ceiling. It's that raw footage hands it ten variables when the only one that matters is how the body is moving. Here's the workflow 1. Lock the character reference in GPT Image 2 first - face, build, outfit, so identity holds no matter how expressive or loose the motion gets 2. Convert the source footage into a depth map instead of feeding the raw video - this strips out the original performer's face, clothing, and environment entirely 3. Feed the depth map as the motion reference and the character sheet as the identity reference - two separate inputs, two separate jobs 4. Let the depth map carry only spatial movement - gesture, weight shift, head turn, with no competing information about who's moving or what they look like 5. Keep the two inputs isolated all the way through - the moment appearance data leaks into the motion reference, the model starts negotiating between two identities Why this works - Raw footage hands the model everything at once, and loose, expressive motion has nowhere near as much rhythm to lean on as dance does - A depth map is pure spatial information, so unscripted gesture reads just as cleanly as choreography - Separating identity from motion means the character stays locked while every twitch and turn still survives intact - The gain isn't a smarter model, it's a model with fewer decisions left to make Use cases: ⁃ Expression and gesture transfer, not just choreography ⁃ Conversational or reactive scenes with no fixed rhythm ⁃ Any footage where identity needs to change but the exact motion can't ⁃ Character showcase content built on found or reference footage The character sheet still answers who's moving. The depth map still answers how - it just turns out how applies to a lot more than dancing.
