README (SKILL.md)
Alibaba Cloud Super Resolution (阿里云视频超分辨率)
Enhance video resolution using Alibaba Cloud's video super resolution API, converting low-resolution videos to higher resolution (e.g., 480p → 960p).
Prerequisites
Set the following environment variables for authentication:
export ALIBABA_CLOUD_ACCESS_KEY_ID="your-access-key-id"
export ALIBABA_CLOUD_ACCESS_KEY_SECRET="your-access-key-secret"
Optional OSS Configuration (for large files)
For files larger than 2GB or when using OSS directly:
export ALIYUN_OSS_BUCKET="your-bucket-name"
export ALIYUN_OSS_ENDPOINT="oss-cn-shanghai.aliyuncs.com"
Execution (Python CLI Tool)
A Python CLI tool is provided at ~/.openclaw/workspace/skills/alibaba-super-resolution/alibaba_super_resolve.py.
Quick Examples
# Basic usage: local file → local HD file
python3 ~/.openclaw/workspace/skills/alibaba-super-resolution/alibaba_super_resolve.py \
--input videos/input-480p.mp4 \
--output videos/output-960p.mp4
# Custom bit rate (higher = better quality, larger file)
python3 ~/.openclaw/workspace/skills/alibaba-super-resolution/alibaba_super_resolve.py \
--input videos/input-480p.mp4 \
--output videos/output-960p.mp4 \
--bit-rate 8
# Do not wait for completion (return job ID immediately)
python3 ~/.openclaw/workspace/skills/alibaba-super-resolution/alibaba_super_resolve.py \
--input videos/input-480p.mp4 \
--no-wait
# Check status of an existing job
python3 ~/.openclaw/workspace/skills/alibaba-super-resolution/alibaba_super_resolve.py \
--status \x3CJOB_ID>
# Wait for an existing job and download result
python3 ~/.openclaw/workspace/skills/alibaba-super-resolution/alibaba_super_resolve.py \
--wait \x3CJOB_ID> \
--output videos/output-960p.mp4
Input Requirements
Video Files
- Formats: MP4, MOV, AVI, MKV
- Max Size: 2GB (direct upload) / No limit (OSS URL)
- Max Duration: 30 minutes
- Input Resolutions: 480p, 720p
Output Resolutions
| Input | Output |
|---|---|
| 480p | 960p (2x upscale) |
| 720p | 2K (2x upscale) |
Bit Rate Settings
| Bit Rate | Quality | File Size | Processing Time | Use Case |
|---|---|---|---|---|
| 1-3 | Low | Small | Fast | Preview/Testing |
| 4-6 | Medium | Medium | Medium | Social Media |
| 7-10 | High | Large | Slow | HD Publishing |
Rules
- Always check that credentials are configured before making API calls.
- Files over 2GB must use OSS URL instead of direct upload.
- Default bit rate: 5 (balanced quality/size).
- Default timeout: 1200 seconds (20 minutes).
- Download immediately - output URLs expire after 24 hours.
- Handle errors gracefully - display clear error messages.
Troubleshooting
VideoTooLarge
Error: File exceeds 2GB limit
Fix: Use OSS URL instead of direct upload
Timeout
Error: Task timed out
Fix: Increase timeout parameter: --timeout 1800 (30 minutes)
OSSAccessDenied
Error: OSSAccessDenied
Fix: Verify RAM permissions for the access key, ensure it has OSS read/write access.

Usage Guidance
This skill appears to do what it says: call Alibaba Cloud's video super-resolution API. Before installing or running it, verify the source (repository/author) since the package owner is 'unknown' in the registry. Provide only an Alibaba RAM key with the minimal permissions required (videoenhan and OSS read/write if you use OSS), preferably a temporary/key with narrow scope. Review the requirements.txt and installed packages (alibabacloud_videoenhan SDK and requests) and consider installing in a virtualenv. Note the registry metadata omitted the required env vars — set ALIBABA_CLOUD_ACCESS_KEY_ID and ALIBABA_CLOUD_ACCESS_KEY_SECRET as described in SKILL.md. If you will upload sensitive videos, confirm you trust the destination (the code defaults to endpoint videoenhan.cn-shanghai.aliyuncs.com) and understand that uploaded videos will be sent to Alibaba Cloud and output URLs expire (24h).
Capability Analysis
Type: OpenClaw Skill
Name: alibaba-super-resolution
Version: 0.1.0
The skill bundle provides a legitimate interface for the Alibaba Cloud Video Super Resolution API. The Python script (alibaba_super_resolve.py) handles authentication via standard environment variables, performs file uploads to Alibaba Cloud, and downloads processed results using the requests library. There is no evidence of data exfiltration, malicious command execution, or prompt injection; the code logic is consistent with the stated purpose of video enhancement.
Capability Assessment
Purpose & Capability
Name/description claim to use Alibaba Cloud Super Resolution; the SKILL.md and the Python code both require ALIBABA_CLOUD_ACCESS_KEY_ID and ALIBABA_CLOUD_ACCESS_KEY_SECRET (and optionally OSS settings) which are appropriate and expected for this purpose. The registry metadata, however, lists no required environment variables — an omission in the metadata but not a functional mismatch.
Instruction Scope
SKILL.md and the CLI code limit actions to uploading a local video (or using OSS), submitting jobs to Alibaba Cloud, polling job status, and downloading results. The instructions reference only the Alibaba credentials and optional OSS config; they do not instruct reading unrelated system files or sending data to unexpected endpoints. The code uses the Alibaba SDK and requests to download output URLs.
Install Mechanism
There is no automated install spec (instruction-only install) and dependencies are declared in requirements.txt (pip). This is low-risk; install-time actions are limited to installing Python packages from PyPI, and no arbitrary archive downloads or unknown URLs are used.
Credentials
Requested credentials (ALIBABA_CLOUD_ACCESS_KEY_ID, ALIBABA_CLOUD_ACCESS_KEY_SECRET) and optional OSS variables are proportionate to the skill's functionality. The SKILL.md explicitly asks for them. The only issue is the registry metadata failing to declare these required env vars — users should be aware the skill will attempt to read those environment variables at runtime.
Persistence & Privilege
The skill is not always-enabled, does not request elevated platform privileges, and does not attempt to modify other skills or global agent config. It runs as a CLI tool invoked by the user/agent and does not persist additional privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
