What it makes

Section titled “What it makes”

Two videos and a comparison slider. The template sends a video you pick to vCube, which restores and upscales it to 1080p. You get the enhanced video, a second video in which a divider sweeps across the frame to show before and after, and a pair of still frames for a side-by-side slider.

The workflow

Section titled “The workflow”
The vCube Video Enhance template: Load Video into the vCube node, which feeds two Save Video nodes and a Compare Images node
Load Video feeds the vCube node; its outputs go to two Save Video nodes and Compare Images.
  1. Load Video supplies the source video. The template ships with no file chosen, so pick one with choose file to upload.
  2. vCube Video Enhance uses tool_version standard with scene aigc and enhance_style hd, resolution 1080p, fps source and bitrate_level medium. comparison is on, so it also builds the comparison outputs.
  3. Save Enhanced Video keeps the enhanced video.
  4. Save Comparison Video keeps the video with the sweeping divider.
  5. Compare Images receives source_frame and enhanced_frame. It is the slider view and works in Nodes 2.0 only.

Run it

Section titled “Run it”
  1. Add your AI MediaKit API key in Settings → BytePlus if you have not yet (API keys). This is a separate key from the ModelArk key.
  2. Log in to your Comfy.org account in ComfyUI. A connected video is uploaded to Comfy.org storage first, because AI MediaKit only takes links. To skip that, remove Load Video and set video_url on the vCube node to a public link instead.
  3. Open the template browser and choose vCube Video Enhance under BytePlus.
  4. In Load Video, pick a video of your own.
  5. Press Run. The two videos appear in the Save Video nodes and the frames in Compare Images when the task finishes.

Settings worth changing

Section titled “Settings worth changing”
  • scene: match the footage. aigc is for AI-generated video, common for general video, ugc for compressed phone clips, short_series for drama with faces and old_film for scratched or flickering archive footage.
  • enhance_style: hd sharpens more; natural is softer.
  • resolution: choose 720p, 2k, 4k, 8k, source or custom. The source video must be at most 2560x1440.
  • fps: a higher rate than the source adds interpolated frames. The node tooltip says rates above 30 fps cost 2x and above 60 fps 4x.
  • tool_version: professional restores more thoroughly. The tooltip says it takes about 3x longer and costs 10x more than standard.

Example result

Section titled “Example result”

The enhanced video from this example.

Time and cost

Section titled “Time and cost”

The task bills on AI MediaKit once per run, and the price depends on the settings above. Running again with an unchanged workflow and the same video reuses ComfyUI’s cached result and does not bill. The comparison is built on your computer after the download, so it adds no MediaKit charge.
