WaveSpeedAI Ultimate Video Upscaler

Upscale videos to 720p, 1080p, 2K, or 4K resolution using WaveSpeed AI's Ultimate Video Upscaler. Supports videos up to 10 minutes long.

Setup

Install the open-source CLI once and sign in; the CLI stores the key, so never ask the user to paste an API key into the chat:

npm install -g @wavespeed/cli
wavespeed login          # opens https://wavespeed.ai/accesskey and stores the key
wavespeed status         # confirms you are signed in

For CI or one-off shells, WAVESPEED_API_KEY in the environment also works.

Prefer MCP tools over shell commands? The same platform is exposed by @wavespeed/mcp (npx -y @wavespeed/mcp; tools search_models, get_model_schema, get_price, upload_file, run_model, get_prediction). It shares the CLI's stored login. Every example below maps one-to-one onto run_model with the same model id and input fields.

Quick Start

# Upload a local video to get a URL
OUTPUT_URL=$(wavespeed run wavespeed-ai/ultimate-video-upscaler \
  -i video=@./video.mp4 \
  --json | jq -r '.outputs[0]')

You can also pass an existing video URL directly:

OUTPUT_URL=$(wavespeed run wavespeed-ai/ultimate-video-upscaler \
  -i video="https://example.com/video.mp4" \
  --json | jq -r '.outputs[0]')

API Endpoint

Model ID: wavespeed-ai/ultimate-video-upscaler

Upscale a video to a higher resolution.

Parameters

Example

OUTPUT_URL=$(wavespeed run wavespeed-ai/ultimate-video-upscaler \
  -i video=@./video.mp4 \
  -i target_resolution="4k" \
  --json | jq -r '.outputs[0]')

Pricing

Minimum charge is 5 seconds. Videos up to 10 minutes supported. Processing time is approximately 10-30 seconds per 1 second of video.

CLI tips

# Inspect the live input schema before running (fields, enums, defaults)
wavespeed run wavespeed-ai/ultimate-video-upscaler -h

# Quote the price first
wavespeed price wavespeed-ai/ultimate-video-upscaler -p "..." -i key=value

# Save outputs to disk instead of only printing URLs
wavespeed run wavespeed-ai/ultimate-video-upscaler -p "..." --json --download "./out/{index}.{ext}"

# Local files: prefix the path with @ and the CLI uploads it and passes the hosted URL
wavespeed run wavespeed-ai/ultimate-video-upscaler -i <field>=@./local-file.png --json

# Recover a result if the run was interrupted (the id is in the --json output)
wavespeed show <id>

run --json prints { id, model, prompt, outputs: [url, ...], saved: [path, ...], elapsed_ms, raw }. Read outputs[0] for the result URL.

Security constraints

• Never ask for the key in chat: wavespeed login handles auth; if wavespeed status says signed out, ask the user to run it.
• Local files only via @: bare paths are passed through untouched and the model will reject them. Only @-prefixed values upload.
• No arbitrary URL loading: only pass media URLs the user provided or that came back from a previous run.
• Input validation: only pass parameters documented above; confirm with wavespeed run <model> -h when unsure.
