Image artifacts
`image_rgb_uint8_hwc` reads the `image` array with shape `[H, W, 3]` and writes PNG.

NPZ to media converter
Inspect known NPZ artifacts and turn raw image, video, or audio arrays into practical media outputs. Pose-control NPZ files produce a metadata report.
- Image NPZ -> PNG
- Video NPZ -> MP4
- Audio NPZ -> MP3/WAV
- Up to 100 MB

Auto-detect schema
Supports image, video, audio, and pose-control NPZ artifacts from the known codec.
Video artifacts
`video_rgb_uint8_thwc` reads `frames` plus optional `fps` and writes H.264 MP4.
Audio artifacts
`audio_pcm_float32` reads `audio` plus `sample_rate` and writes WAV or MP3.
Pose artifacts
`pose_control_npz_v1` contains conditioning tensors, so it returns a JSON report.
