Video Output Bridge

A tiny ComfyUI custom node built to unblock RunPod's worker-comfyui deployments. It converts VHS_VideoCombine outputs into the standard images payload so serverless runners (RunPod, Modal, etc.) can pick up rendered MP4/WebP files automatically.

Why?

Some providers only inspect the images field in the workflow history when collecting artifacts. VHS_VideoCombine writes its metadata under gifs, which means otherwise successful jobs return success_no_images. This node simply maps those filenames back into the images list without touching the actual video files.

Usage

1. Install the node (either from the Comfy registry or by copying this folder into your custom_nodes directory).
2. Connect the VHS_FILENAMES output from VHS_VideoCombine into the filenames input on VideoOutputBridge.
3. Trigger the node as the final output. The workflow history will now contain the video filenames under images, allowing external tooling to upload or download the MP4 files.

RunPod Worker configuration

If you are using RunPod's worker-comfyui, make sure the worker is configured to upload artifacts to your S3 bucket; otherwise the registry sees the filenames but nothing is exported. Follow the environment variable guide in the official Configuration Guide to set the required S3 bucket, access key, and upload toggles.
