VDN-H3

Tools

• VDN_H3_generate Generate a 1344x768 video with a synchronised soundtrack from a text prompt. Returns: A tuple of the path to the generated MP4 (H.264 video + AAC audio) and a Markdown, line reporting the measured GPU timings.
• VDN_H3_generate_conditioned Generate from a Qwen3-VL conditioning file produced by the companion conditioner Space. This endpoint exists for browser clients that can authenticate both ZeroGPU calls as the signed-in visitor. It avoids making an anonymous server-to-server conditioner request, which otherwise receives only the Space owner's tiny unauthenticated quota and fails before VDN ever reaches its GPU worker. If a user passes a file as an input, use the upload_file_to_gradio tool, if present, to upload the file to the gradio app and create a Gradio File Input. Then use the returned path as the input to the tool
• VDN_H3_generate_conditioned_b64 Generate from inline conditioning bytes, bypassing Gradio's remote-file downloader. Cross-Space FileData URLs can be scoped to the caller's browser identity. Gradio otherwise asks this Space to download that URL during input preprocessing, where it has no caller cookie and receives HTTP 403. An inline payload is small (only the prompt tokens), deterministic, and reaches the function without URL normalization.

As the server's own listing gives them. We never call a tool.
