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 <JOB_ID>

# Wait for an existing job and download result
python3 ~/.openclaw/workspace/skills/alibaba-super-resolution/alibaba_super_resolve.py \
  --wait <JOB_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.
