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

1. Always check that credentials are configured before making API calls.
2. Files over 2GB must use OSS URL instead of direct upload.
3. Default bit rate: 5 (balanced quality/size).
4. Default timeout: 1200 seconds (20 minutes).
5. Download immediately - output URLs expire after 24 hours.
6. 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.
