video-resolution-upscale

Video Resolution Upscale

Overview

Call meitu video-resolution-upscale for dedicated video resolution super-resolution (720P/1080P/2K/4K).Pixel-level resolution reconstruction only, no image quality restoration, no deblurring, no denoising, no frame interpolation, no color grading, no brightness adjustment, keeping the original visual style unchanged.

Not handled: comprehensive image quality restoration (without any resolution signal), frame interpolation/smoothness, video denoising, video night scene enhancement, image super-resolution.

API Mapping

DAG tool	backend API
video-resolution-upscale	video_superres_enhance

Dependencies

• meitu-cli: >=2.0.6
• credentials：CONFIG AKSK → meitu tools update; EXEC AKSK → run command
• environment variables：MEITU_OPENAPI_TOOL_TASK_MODE=command

Path alias:$VISUAL = {OPENCLAW_HOME}/workspace/visual/

Core Workflow

Preflight → Execute → Deliver

Preflight

1. meitu --version ≥ 2.0.6；meitu auth verify --json
2. Confirm Config Phase has been run;MEITU_OPENAPI_TOOL_TASK_MODE=command
3. output_dir resolution: openclaw.yaml → ./output/ | else → $VISUAL/output/video-resolution-upscale/；mkdir -p {output_dir}

Execute

Trigger signals/routing (two-layer determination)

• First layer (enter the flow): contains any signal of "resolution / super-resolution / upscale / upscale clarity / 720P / 1080P / 2K / 4K"
• Second layer (direct call vs follow-up question): target value already specified → direct call; not specified ("resolution too low"/"upscale a bit") → follow-up question

Decision order:

1. Contains resolution-related request? No → this tool does not handle it (outside capability scope, guide to video-quality-enhance）
2. Target resolution clarity: no specific value → prompt "Please specify the target resolution: 720P / 1080P / 2K / 4K"
3. video_url missing → follow-up question
4. Target resolution must be higher than the original video
5. Unique route → video_superres_enhance

Example:

• "Upscale the video to 4K" → target_resolution=4K
• "Restore a blurry old video to 4K" → target_resolution=4K(contains resolution request, handled by this tool)
• "Help me restore this video" → this tool does not handle it (no resolution request)

Parameter definitions

Parameter	Type	Required	Range	Default value	Description
video_url	STRING	Yes	--	--	Video URL; if missing → "Please provide the video link"
target_resolution	STRING	Yes	720p / 1080p / 2K / 4K	--	Must be explicitly provided by the user, no default value; higher than the original video resolution

Without target_resolution , this tool cannot be called。

Tool invocation

meitu video-resolution-upscale \
  --skill_name skill_video-resolution-upscale \
  --video_url {video_url} \
  --target_resolution {720p|1080p|2K|4K} \
  --json --download-dir {output_dir}

Error fallback

Scenario	Handling
video_url missing	Prompt "Please provide the video link"
video_url inaccessible	Do not retry, prompt "Please provide a valid video link"
target_resolution missing but has resolution request	Prompt "Please specify the target resolution: 720P/1080P/2K/4K"
target_resolution missing and no resolution request at all	This tool does not handle it, return outside capability scope
Target resolution ≤ original video	Do not call, prompt "Target resolution must be higher than the original video"
target_resolution invalid value	Prompt "Only 720P/1080P/2K/4K are supported"
Call failed	Retry once, if still failing return an error
Timeout	Retry once at a lower target resolution; if it still times out, return an error
Content compliance interception	Return the compliance prompt directly without retrying
Input is an image	Reject; this tool only processes videos

Deliver

Parse --json → downloaded_files[0].saved_path or media_urls[0]. Ultra-high resolution (4K) takes longer to process.

mv {file} {output_dir}/{YYYY-MM-DD}_{name}_{target_resolution}.mp4

Output

• Format: MP4 (target 720p/1080p/2K/4K)
• Naming：{YYYY-MM-DD}_{descriptive-name}_{target_resolution}.mp4
• Location: Project → ./output/; one-time → $VISUAL/output/video-resolution-upscale/
