GPT Image 2.5 makes 4x4 single-color chibi sheet for auto-keyed transparent video

The author generated a 4x4 single-color chibi character image with GPT Image 2.5, turned it into video with MiniMax H3, then auto chroma-keyed it in ComfyUI for a transparent-background video, taking about 200 seconds at 720p on an RTX 4070.

GPT Image 2.5で4x4のちびキャラ単一色画像を作って、それをMiniMax H3で動画にした後で自動クロマキーした背景透過動画を作成してみたー。色被りしなければ割と綺麗に抜けるしクロマキーもComfyUIだけで実装できる。720pでRTX4070で200秒くらい。
