8-bit video pipeline

Two-step pipeline that turns a portrait photo into a short pixel-art video clip:

1. Stylize. Gemini converts the photo into an 8-bit still PNG.
2. Animate. Replicate's bytedance/seedance-2.0 uses that still as the first frame to generate an MP4.

Both scripts live in scripts/ and use PEP 723 inline script metadata, so uv run resolves their dependencies automatically.

If the user only wants the still, run step 1 and stop. If they already have an 8-bit image, skip to step 2.

Setup

Before running either script:

1. Verify uv is installed: uv --version. If missing, ask the user to install it (https://docs.astral.sh/uv/getting-started/installation/). The scripts declare their Python dependencies inline (PEP 723 metadata), so uv run handles the rest.
