## When to Use This Skill
|
||||
|
||||
Activate this skill when:
|
||||
- Correcting speech-to-text (ASR) transcription errors in meeting notes, lectures, or interviews
|
||||
- Building domain-specific correction dictionaries for repeated transcription workflows
|
||||
- Fixing Chinese/English homophone errors, technical terminology, or names
|
||||
- Collaborating with teams on shared correction knowledge bases
|
||||
- Improving transcript accuracy through iterative learning
|
||||
- Correcting ASR/STT errors in meeting notes, lectures, or interviews
|
||||
- Building domain-specific correction dictionaries
|
||||
- Fixing Chinese/English homophone errors or technical terminology
|
||||
- Collaborating on shared correction knowledge bases
|
||||
|
||||
## Quick Start
|
||||
|
||||
Initialize (first time only):
|
||||
**Recommended: Use Enhanced Wrapper** (auto-detects API key, opens HTML diff):
|
||||
|
||||
```bash
|
||||
# First time: Initialize database
|
||||
uv run scripts/fix_transcription.py --init
|
||||
export GLM_API_KEY="<api-key>" # Obtain from https://open.bigmodel.cn/
|
||||
|
||||
# Process transcript with enhanced UX
|
||||
uv run scripts/fix_transcript_enhanced.py input.md --output ./corrected
|
||||
```
|
||||
|
||||
Correct a transcript in 3 steps:
|
||||
The enhanced wrapper automatically:
|
||||
- Detects GLM API key from shell configs (checks lines near `ANTHROPIC_BASE_URL`)
|
||||
- Moves output files to specified directory
|
||||
- Opens HTML visual diff in browser for immediate feedback
|
||||
|
||||
**Alternative: Use Core Script Directly**:
|
||||
|
||||
```bash
|
||||
# 1. Add common corrections (5-10 terms)
|
||||
# 1. Set API key (if not auto-detected)
|
||||
export GLM_API_KEY="<api-key>" # From https://open.bigmodel.cn/
|
||||
|
||||
# 2. Add common corrections (5-10 terms)
|
||||
uv run scripts/fix_transcription.py --add "错误词" "正确词" --domain general
|
||||
|
||||
# 2. Run full correction pipeline
|
||||
# 3. Run full correction pipeline
|
||||
uv run scripts/fix_transcription.py --input meeting.md --stage 3
|
||||

|
||||
Three-stage pipeline stores corrections in `~/.transcript-fixer/corrections.db`:
|
||||
|
||||
```markdown
|
||||
### Transcript Correction - [FILENAME] - [DATE]

- [ ] Validation passed: `uv run scripts/fix_transcription.py --validate`
|
||||
- [ ] GLM_API_KEY verified: `echo $GLM_API_KEY | wc -c` (should be >20)

|
||||
- [ ] Learned patterns reviewed: `--review-learned`
|
||||
- [ ] High-confidence suggestions approved (if any)
|
||||
- [ ] Team dictionary updated (if applicable): `--export team.json`
|

```
|
||||
1. **Initialize** (first time): `uv run scripts/fix_transcription.py --init`
|
||||
2. **Add domain corrections**: `--add "错误词" "正确词" --domain <domain>`
|
||||
3. **Process transcript**: `--input file.md --stage 3`
|
||||
4. **Review learned patterns**: `--review-learned` and `--approve` high-confidence suggestions
|
||||
|
||||
## Core Commands
|
||||
**Stages**: Dictionary (instant, free) → AI via GLM API (parallel) → Full pipeline
|
||||
**Domains**: `general`, `embodied_ai`, `finance`, `medical` (isolates corrections)
|
||||
**Learning**: Patterns appearing ≥3 times at ≥80% confidence move from AI to dictionary
|
||||
|
||||
```bash
|
||||
# Initialize (first time only)
|
||||
uv run scripts/fix_transcription.py --init
|
||||
export GLM_API_KEY="<api-key>" # Get from https://open.bigmodel.cn/
|
||||
|
||||
# Add corrections
|
||||
uv run scripts/fix_transcription.py --add "错误词" "正确词" --domain general
|
||||
|
||||
# Run full pipeline (dictionary + AI corrections)
|
||||
uv run scripts/fix_transcription.py --input file.md --stage 3 --domain general
|
||||
|
||||
# Review and approve learned patterns (after 3-5 runs)
|
||||
uv run scripts/fix_transcription.py --review-learned
|
||||
uv run scripts/fix_transcription.py --approve "错误" "正确"
|
||||
|
||||
# Team collaboration
|
||||
uv run scripts/fix_transcription.py --export team.json --domain <domain>
|
||||
uv run scripts/fix_transcription.py --import team.json --merge
|
||||
|
||||
# Validate setup
|
||||
uv run scripts/fix_transcription.py --validate
|
||||
```
|
||||
|
||||
**Database**: `~/.transcript-fixer/corrections.db` (SQLite)
|
||||
|
||||
**Stages**:
|
||||
- Stage 1: Dictionary corrections (instant, zero cost)
|
||||
- Stage 2: AI corrections via GLM API (1-2 min per 1000 lines)
|
||||
- Stage 3: Full pipeline (both stages)
|
||||
|
||||
**Domains**: `general`, `embodied_ai`, `finance`, `medical` (prevents cross-domain conflicts)
|
||||
|
||||
**Learning**: Approve patterns appearing ≥3 times with ≥80% confidence to move from expensive AI (Stage 2) to free dictionary (Stage 1).

|
||||
```
|
||||
|
||||
**Error recovery:**
|
||||
1. Run validation to identify issue
|
||||
2. Check components:
|
||||
- Database: `sqlite3 ~/.transcript-fixer/corrections.db ".tables"`
|
||||
- API key: `echo $GLM_API_KEY | wc -c` (should be >20)
|
||||
- Permissions: `ls -la ~/.transcript-fixer/`
|
||||
3. Apply fix based on validation output
|
||||
4. Re-validate to confirm
|
||||
|
||||
**Quick fixes:**
|
||||
Verify setup health with `uv run scripts/fix_transcription.py --validate`. Common issues:
|
||||
- Missing database → Run `--init`
|
||||
- Missing API key → `export GLM_API_KEY="<key>"`
|
||||
- Permission errors → Check ownership with `ls -la`
|
||||
- Missing API key → `export GLM_API_KEY="<key>"` (obtain from https://open.bigmodel.cn/)
|
||||
- Permission errors → Check `~/.transcript-fixer/` ownership
|
||||
|
||||

- Network failures and retries
|

- File system errors
|

- Concurrent access conflicts
|

- Resource exhaustion
|

CRITICAL FIX (P1-11): Production-grade audit log retention and compliance
|
||||
|
||||
Features:
|
||||
- Configurable retention policies per entity type
|
||||
- Automatic cleanup of expired logs
|
||||
- Archive capability for long-term storage
|
||||
- Compliance reporting (GDPR, SOX, etc.)
|
||||
- Selective retention based on criticality
|
||||
- Restoration from archives
|
||||
|
||||
Compliance Standards:
|
||||
- GDPR: Right to erasure, data minimization
|
||||
- SOX: 7-year retention for financial records
|
||||
- HIPAA: 6-year retention for healthcare data
|
||||
- Industry best practices

- Centralized configuration (single source of truth)
|

- Environment-based config (dev/staging/prod)
|

- Type-safe access with validation
|
||||
- Multiple config sources (env vars, files, defaults)
|

- Config schema validation
|

- Secure secrets management
|

Use cases:
|

- Application configuration
|

- Environment-specific settings
|

- Gauge: Point-in-time value (e.g., active connections)
|
||||
- Histogram: Distribution of values (e.g., response times)

CRITICAL FIX (P1-8): Production-grade rate limiting for API protection
|

Features:
|

- Token Bucket algorithm (smooth rate limiting)
|

- Sliding Window algorithm (precise rate limiting)
|

- Fixed Window algorithm (simple, memory-efficient)
|
||||
- Thread-safe operations
|
||||
- Burst support
|
||||
- Multiple rate limit tiers
|
||||
- Metrics integration
|
||||
|
||||
Use cases:
|
||||
- API rate limiting (e.g., 100 requests/minute)
|
||||
- Resource protection (e.g., max 5 concurrent DB connections)
|
||||
- DoS prevention
|

- Cost control (e.g., limit API calls)

|
||||
|
||||
## Configuration
|
||||
|
||||
### Constants in `scripts/compare.py`
|
||||
|
||||
```python
|
||||
ALLOWED_EXTENSIONS = {'.mp4', '.mov', '.avi', '.mkv', '.webm'}
|
||||
MAX_FILE_SIZE_MB = 500 # Maximum file size limit
|
||||
FFMPEG_TIMEOUT = 300 # FFmpeg timeout (5 minutes)
|
||||
FFPROBE_TIMEOUT = 30 # FFprobe timeout (30 seconds)
|
||||
BASE_FRAME_HEIGHT = 800 # Frame height for comparison
|
||||
FRAME_INTERVAL = 5 # Default frame extraction interval
|
||||
```
|
||||
|
||||
### Customizing Frame Resolution
|
||||
|
||||
To change the frame resolution for comparison:
|
||||
|
||||
```python
|
||||
# In scripts/compare.py
|
||||
BASE_FRAME_HEIGHT = 1200 # Higher resolution (larger file size)
|
||||
# or
|
||||
BASE_FRAME_HEIGHT = 600 # Lower resolution (smaller file size)
|
||||
```
|
||||
|
||||
## Performance
|
||||
|
||||
### Processing Time
|
||||
- **Metadata Extraction**: < 5 seconds
|
||||
- **Quality Metrics**: 1-2 minutes (depends on video duration)
|
||||
- **Frame Extraction**: 30-60 seconds (depends on video length and interval)
|
||||
- **Report Generation**: < 10 seconds
|
||||
|
||||
### File Sizes
|
||||
- **Input Videos**: Up to 500MB each (configurable)
|
||||
- **Generated Report**: 2-5MB (depends on frame count)
|
||||
- **Temporary Files**: Auto-cleaned during processing
|
||||
|
||||
### Resource Usage
|
||||
- **Memory**: ~200-500MB during processing
|
||||
- **Disk Space**: ~100MB temporary files
|
||||
- **CPU**: Moderate (video decoding)
|
||||
|
||||
## Security Features
|
||||
|
||||
### Path Validation
|
||||
- ✅ Converts all paths to absolute paths
|
||||
- ✅ Verifies files exist and are readable
|
||||
- ✅ Checks file extensions against whitelist
|
||||
- ✅ Validates file size before processing
|
||||
|
||||
### Command Injection Prevention
|
||||
- ✅ All subprocess calls use argument lists
|
||||
- ✅ No `shell=True` in subprocess calls
|
||||
- ✅ User input never passed to shell
|
||||
- ✅ FFmpeg arguments validated and escaped
|
||||
|
||||
### Resource Limits
|
||||
- ✅ File size limit enforcement
|
||||
- ✅ Timeout limits for FFmpeg operations
|
||||
- ✅ Temporary files auto-cleanup
|
||||
- ✅ Memory usage monitoring
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### "FFmpeg not found"
|
||||
```bash
|
||||
# Install FFmpeg using your package manager
|
||||
brew install ffmpeg # macOS
|
||||
sudo apt install ffmpeg # Ubuntu/Debian
|
||||
sudo yum install ffmpeg # CentOS/RHEL/Fedora
|
||||
```
|
||||
|
||||
#### "File too large: X MB"
|
||||
```bash
|
||||
# Options:
|
||||
1. Compress videos before comparison
|
||||
2. Increase MAX_FILE_SIZE_MB in compare.py
|
||||
3. Use shorter video clips
|
||||
```
|
||||
|
||||
#### "Operation timed out"
|
||||
```bash
|
||||
# For very long videos:
|
||||
python3 scripts/compare.py original.mp4 compressed.mp4 --interval 10
|
||||
# or
|
||||
# Increase FFMPEG_TIMEOUT in compare.py
|
||||
```
|
||||
|
||||
#### "No frames extracted"
|
||||
- Check if videos are playable in media player
|
||||
- Verify videos have sufficient duration (> interval seconds)
|
||||
- Ensure FFmpeg can decode the codec
|
||||
|
||||
#### "Frame count mismatch"
|
||||
- Videos have different durations or frame rates
|
||||
- Script automatically truncates to minimum frame count
|
||||
- Warning is displayed in output
|
||||
|
||||
### Debug Mode
|
||||
|
||||
Enable verbose output by modifying the script:
|
||||
|
||||
```python
|
||||
# Add at the top of compare.py
|
||||
import logging
|
||||
logging.basicConfig(level=logging.DEBUG)
|
||||
```
|
||||

# Video Comparer
|
||||
|
||||
## Overview
|
||||
|
||||
Compare two videos and generate an interactive HTML report analyzing compression results. The script extracts video metadata, calculates quality metrics (PSNR, SSIM), and creates frame-by-frame visual comparisons with three viewing modes: slider, side-by-side, and grid.
|
||||
|
||||
## When to Use This Skill
|
||||
|
||||
Use this skill when:
|
||||
- Comparing original and compressed videos
|
||||
- Analyzing video compression quality and efficiency
|
||||
- Evaluating codec performance or bitrate reduction impact
|
||||
- Users mention "compare videos", "video quality", "compression analysis", or "before/after compression"
|
||||
|
||||
## Core Usage
|
||||
|
||||
### Basic Command
|
||||
|
||||
```bash
|
||||
python3 scripts/compare.py original.mp4 compressed.mp4
|
||||
```
|
||||
|
||||
Generates `comparison.html` with:
|
||||
- Video parameters (codec, resolution, bitrate, duration, file size)
|
||||
- Quality metrics (PSNR, SSIM, size/bitrate reduction percentages)
|
||||
- Frame-by-frame comparison (default: frames at 5s intervals)
|
||||
|
||||
### Command Options
|
||||
|
||||
```bash
|
||||
# Custom output file
|
||||
python3 scripts/compare.py original.mp4 compressed.mp4 -o report.html
|
||||
|
||||
# Custom frame interval (larger = fewer frames, faster processing)
|
||||
python3 scripts/compare.py original.mp4 compressed.mp4 --interval 10
|
||||
|
||||
# Batch comparison
|
||||
for original in originals/*.mp4; do
|
||||
compressed="compressed/$(basename "$original")"
|
||||
output="reports/$(basename "$original" .mp4).html"
|
||||
python3 scripts/compare.py "$original" "$compressed" -o "$output"
|
||||
done
|
||||
```
|
||||
|
||||
## Requirements
|
||||
|
||||
### System Dependencies
|
||||
|
||||
**FFmpeg and FFprobe** (required for video analysis and frame extraction):
|
||||
|
||||
```bash
|
||||
# macOS
|
||||
brew install ffmpeg
|
||||
|
||||
# Ubuntu/Debian
|
||||
sudo apt update && sudo apt install ffmpeg
|
||||
|
||||
# Windows
|
||||
# Download from https://ffmpeg.org/download.html
|
||||
# Or use: winget install ffmpeg
|
||||
```
|
||||
|
||||
**Python 3.8+** (uses type hints, f-strings, pathlib)
|
||||
|
||||
### Video Specifications
|
||||
|
||||
- **Supported formats:** `.mp4` (recommended), `.mov`, `.avi`, `.mkv`, `.webm`
|
||||
- **File size limit:** 500MB per video (configurable)
|
||||
- **Processing time:** ~1-2 minutes for typical videos; varies by duration and frame interval
|
||||
|
||||
## Script Behavior
|
||||
|
||||
### Automatic Validation
|
||||
|
||||
The script automatically validates:
|
||||
- FFmpeg/FFprobe installation and availability
|
||||
- File existence, extensions, and size limits
|
||||
- Path security (prevents directory traversal)
|
||||
|
||||
Clear error messages with resolution guidance appear when validation fails.
|
||||
|
||||
### Quality Metrics
|
||||
|
||||
The script calculates two standard quality metrics:
|
||||
|
||||
**PSNR (Peak Signal-to-Noise Ratio):** Pixel-level similarity measurement (20-50 dB scale, higher is better)
|
||||
|
||||
**SSIM (Structural Similarity Index):** Perceptual similarity measurement (0.0-1.0 scale, higher is better)
|
||||
|
||||
For detailed interpretation scales and quality thresholds, consult `references/video_metrics.md`.
|
||||
|
||||
### Frame Extraction
|
||||
|
||||
The script extracts frames at specified intervals (default: 5 seconds), scales them to consistent height (800px) for comparison, and embeds them as base64 data URLs in self-contained HTML. Temporary files are automatically cleaned after processing.
|
||||
|
||||
### Output Report
|
||||
|
||||
The generated HTML report includes:
|
||||
- **Slider Mode**: Drag to reveal original vs compressed (default)
|
||||
- **Side-by-Side Mode**: Simultaneous display for direct comparison
|
||||
- **Grid Mode**: Compact 2-column layout
|
||||
- **Zoom Controls**: 50%-200% magnification
|
||||
- Self-contained format (no server required, works offline)
|
||||
|
||||
## Important Implementation Details
|
||||
|
||||
### Security
|
||||
|
||||
The script implements:
|
||||
- Path validation (absolute paths, prevents directory traversal)
|
||||
- Command injection prevention (no `shell=True`, validated arguments)
|
||||
- Resource limits (file size, timeouts)
|
||||
- Custom exceptions: `ValidationError`, `FFmpegError`, `VideoComparisonError`
|
||||
|
||||
### Common Error Scenarios
|
||||
|
||||
**"FFmpeg not found"**: Install FFmpeg via platform package manager (see Requirements section)
|
||||
|
||||
**"File too large"**: Compress videos before comparison, or adjust `MAX_FILE_SIZE_MB` in `scripts/compare.py`
|
||||
|
||||
**"Operation timed out"**: Increase `FFMPEG_TIMEOUT` constant or use larger `--interval` value (processes fewer frames)
|
||||
|
||||
**"Frame count mismatch"**: Videos have different durations/frame rates; script auto-truncates to minimum frame count and shows warning
|
||||
|
||||
## Configuration
|
||||
|
||||
The script includes adjustable constants for file size limits, timeouts, frame dimensions, and extraction intervals. To customize behavior, edit the constants at the top of `scripts/compare.py`. For detailed configuration options and their impacts, consult `references/configuration.md`.
|
||||
|
||||
## Reference Materials
|
||||
|
||||
Consult these files for detailed information:
|
||||
- **`references/video_metrics.md`**: Quality metrics interpretation (PSNR/SSIM scales, compression targets, bitrate guidelines)
|
||||
- **`references/ffmpeg_commands.md`**: FFmpeg command reference (metadata extraction, frame extraction, troubleshooting)
|
||||
- **`references/configuration.md`**: Script configuration options and adjustable constants

<h3>⚠️ 发现的问题</h3>
|
||||
<ul>
|
||||
<li><strong>编码转换损失</strong>: HEVC → H264 转码导致质量下降，尤其是亮度通道</li>
|
||||
<li><strong>PSNR 偏低</strong>: 23.37 dB 表示存在明显的压缩伪影和细节损失</li>
|
||||
<li><strong>亮度细节受损</strong>: Y 通道 PSNR 仅 21.72 dB，细节模糊化明显</li>
|
||||
<li><strong>压缩算法不同</strong>: 微信使用了更激进的压缩策略</li>
|
||||
</ul>

<div class="findings good-news">
|
||||
<h3>✅ 保留较好的方面</h3>
|
||||
<ul>
|
||||
<li><strong>分辨率不变</strong>: 依然保持 1080×1920 的原始分辨率</li>
|
||||
<li><strong>色彩保留好</strong>: 色度通道 PSNR > 33 dB，色彩还原度较高</li>
|
||||
<li><strong>结构相似度高</strong>: SSIM 0.873 说明整体结构和内容保持良好</li>
|
||||
<li><strong>码率基本不变</strong>: 从 6.89 → 6.91 Mbps，带宽消耗相近</li>

<h3 style="color: #0066cc; margin-bottom: 15px;">💡 技术解释</h3>
|
||||
<p style="color: #004080; line-height: 1.8; margin-bottom: 10px;">
|
||||
<strong>为什么感觉模糊？</strong><br>
|
||||
主要原因是微信视频号将你的 HEVC（H.265）视频重新编码为 H264（H.265 压缩效率更高）。
|
||||
虽然码率几乎相同，但 H264 在相同码率下的画质不如 HEVC，导致细节损失。
|
||||
</p>
|
||||
<p style="color: #004080; line-height: 1.8; margin-bottom: 10px;">
|
||||
<strong>PSNR 和 SSIM 含义：</strong><br>
|
||||
• PSNR > 30 dB: 优秀<br>
|
||||
• 20-30 dB: 有损压缩，可见损失<br>
|
||||
• SSIM > 0.9: 几乎无损<br>
|
||||
• 0.8-0.9: 轻微损失<br>
|
||||
你的视频 PSNR=23.37, SSIM=0.873，属于典型的有损压缩。
|
||||
</p>
|
||||
<p style="color: #004080; line-height: 1.8;">
|
||||
<strong>建议：</strong><br>
|
||||
如果希望保持更好的画质，可以尝试上传前降低原始视频的码率（如 4-5 Mbps），
|
||||
这样微信重新编码时损失会更小。或者直接上传 H264 编码的视频。

|
||||
|
||||
## Contents

|
||||
- [Frame Extraction Settings](#frame-extraction-settings) - Visual comparison parameters
|
||||
- [Configuration Impact](#configuration-impact) - Performance and quality tradeoffs
|
||||
|
||||
## Adjustable Constants
|
||||
|
||||
All configuration constants are defined at the top of `scripts/compare.py`:
|
||||
|
||||
```python
|
||||
ALLOWED_EXTENSIONS = {'.mp4', '.mov', '.avi', '.mkv', '.webm'}
|
||||
MAX_FILE_SIZE_MB = 500 # Maximum file size per video
|
||||
FFMPEG_TIMEOUT = 300 # FFmpeg timeout (seconds) - 5 minutes
|
||||
FFPROBE_TIMEOUT = 30 # FFprobe timeout (seconds) - 30 seconds
|
||||
BASE_FRAME_HEIGHT = 800 # Frame height for comparison (pixels)
|
||||
FRAME_INTERVAL = 5 # Default extraction interval (seconds)
|
||||
```
|
||||
|
||||
## File Processing Limits
|
||||
|
||||
### MAX_FILE_SIZE_MB
|
||||
|
||||
**Default:** 500 MB
|
||||
|
||||
**Purpose:** Prevents memory exhaustion when processing very large videos.
|
||||
|
||||
**When to increase:**
|
||||
- Working with high-resolution or long-duration source videos
|
||||
- System has ample RAM (16GB+)
|
||||
- Processing 4K or 8K content
|
||||
|
||||
**When to decrease:**
|
||||
- Limited system memory
|
||||
- Processing on lower-spec machines
|
||||
- Batch processing many videos simultaneously
|
||||
|
||||
**Impact:** No effect on output quality, only determines which files can be processed.
|
||||
|
||||
### FFMPEG_TIMEOUT
|
||||
|
||||
**Default:** 300 seconds (5 minutes)
|
||||
|
||||
**Purpose:** Prevents FFmpeg operations from hanging indefinitely.
|
||||
|
||||
**When to increase:**
|
||||
- Processing very long videos (>1 hour)
|
||||
- Extracting many frames (small `--interval` value)
|
||||
- Slow storage (network drives, external HDDs)
|
||||
- High-resolution videos (4K, 8K)
|
||||
|
||||
**Recommended values:**
|
||||
- Short videos (<10 min): 120 seconds
|
||||
- Medium videos (10-60 min): 300 seconds (default)
|
||||
- Long videos (>60 min): 600-900 seconds
|
||||
|
||||
**Impact:** Operation fails if exceeded; does not affect output quality.
|
||||
|
||||
### FFPROBE_TIMEOUT
|
||||
|
||||
**Default:** 30 seconds
|
||||
|
||||
**Purpose:** Prevents metadata extraction from hanging.
|
||||
|
||||
**When to increase:**
|
||||
- Accessing videos over slow network connections
|
||||
- Processing files with complex codec structures
|
||||
- Corrupt or malformed video files
|
||||
|
||||
**Typical behavior:** Metadata extraction usually completes in <5 seconds; longer times suggest file issues.
|
||||
|
||||
**Impact:** Operation fails if exceeded; does not affect output quality.
|
||||
|
||||
## Frame Extraction Settings
|
||||
|
||||
### BASE_FRAME_HEIGHT
|
||||
|
||||
**Default:** 800 pixels
|
||||
|
||||
**Purpose:** Standardizes frame dimensions for side-by-side comparison.
|
||||
|
||||
**When to increase:**
|
||||
- Comparing high-resolution videos (4K, 8K)
|
||||
- Analyzing fine details or subtle compression artifacts
|
||||
- Generating reports for large displays
|
||||
|
||||
**When to decrease:**
|
||||
- Faster processing and smaller HTML output files
|
||||
- Viewing reports on mobile devices or small screens
|
||||
- Limited bandwidth for sharing reports
|
||||
|
||||
**Recommended values:**
|
||||
- Mobile/low-bandwidth: 480-600 pixels
|
||||
- Desktop viewing: 800 pixels (default)
|
||||
- High-detail analysis: 1080-1440 pixels
|
||||
- 4K/8K analysis: 2160+ pixels
|
||||
|
||||
**Impact:** Higher values increase HTML file size and processing time but preserve more detail.
|
||||
|
||||
### FRAME_INTERVAL
|
||||
|
||||
**Default:** 5 seconds
|
||||
|
||||
**Purpose:** Controls frame extraction frequency.
|
||||
|
||||
**When to decrease (extract more frames):**
|
||||
- Analyzing fast-motion content
|
||||
- Detailed temporal analysis needed
|
||||
- Short videos where more samples help
|
||||
|
||||
**When to increase (extract fewer frames):**
|
||||
- Long videos to reduce processing time
|
||||
- Reducing HTML output file size
|
||||
- Overview analysis (general quality check)
|
||||
|
||||
**Recommended values:**
|
||||
- Fast-motion/detailed: 1-3 seconds
|
||||
- Standard analysis: 5 seconds (default)
|
||||
- Long-form content: 10-15 seconds
|
||||
- Quick overview: 30-60 seconds
|
||||
|
||||
**Impact:**
|
||||
- Smaller intervals: More frames, larger HTML, longer processing, more comprehensive analysis
|
||||
- Larger intervals: Fewer frames, smaller HTML, faster processing, may miss transient artifacts
|
||||
|
||||
## Configuration Impact
|
||||
|
||||
### Processing Time
|
||||
|
||||
Processing time is primarily affected by:
|
||||
1. Video duration
|
||||
2. `FRAME_INTERVAL` (smaller = more frames = longer processing)
|
||||
3. `BASE_FRAME_HEIGHT` (higher = more pixels = longer processing)
|
||||
4. System CPU/storage speed
|
||||
|
||||
**Typical processing times:**
|
||||
- 5-minute video, 5s interval, 800px height: ~45-90 seconds
|
||||
- 30-minute video, 5s interval, 800px height: ~3-5 minutes
|
||||
- 60-minute video, 10s interval, 800px height: ~4-7 minutes
|
||||
|
||||
### HTML Output Size
|
||||
|
||||
HTML file size is primarily affected by:
|
||||
1. Number of extracted frames
|
||||
2. `BASE_FRAME_HEIGHT` (higher = larger base64-encoded images)
|
||||
3. Video complexity (detailed frames compress less efficiently)
|
||||
|
||||
**Typical HTML sizes:**
|
||||
- 5-minute video, 5s interval, 800px: 5-10 MB
|
||||
- 30-minute video, 5s interval, 800px: 20-40 MB
|
||||
- 60-minute video, 10s interval, 800px: 30-50 MB
|
||||
|
||||
### Quality vs Performance Tradeoffs
|
||||
|
||||
**High Quality Configuration (detailed analysis):**
|
||||
```python
|
||||
MAX_FILE_SIZE_MB = 2000
|
||||
FFMPEG_TIMEOUT = 900
|
||||
BASE_FRAME_HEIGHT = 1440
|
||||
FRAME_INTERVAL = 2
|
||||
```
|
||||
Use case: Detailed quality analysis, archival comparison, professional codec evaluation
|
||||
|
||||
**Balanced Configuration (default):**
|
||||
```python
|
||||
MAX_FILE_SIZE_MB = 500
|
||||
FFMPEG_TIMEOUT = 300
|
||||
BASE_FRAME_HEIGHT = 800
|
||||
FRAME_INTERVAL = 5
|
||||
```
|
||||
Use case: Standard compression analysis, typical desktop viewing
|
||||
|
||||
**Fast Processing Configuration (quick overview):**
|
||||
```python
|
||||
MAX_FILE_SIZE_MB = 500
|
||||
FFMPEG_TIMEOUT = 180
|
||||
BASE_FRAME_HEIGHT = 600
|
||||
FRAME_INTERVAL = 10
|
||||
```
|
||||
Use case: Batch processing, quick quality checks, mobile viewing
|
||||
|
||||
## Allowed File Extensions
|
||||
|
||||
**Default:** `{'.mp4', '.mov', '.avi', '.mkv', '.webm'}`
|
||||
|
||||
**Purpose:** Restricts input to known video formats.
|
||||
|
||||
**When to modify:**
|
||||
- Adding support for additional container formats (e.g., `.flv`, `.m4v`, `.wmv`)
|
||||
- Restricting to specific formats for workflow standardization
|
||||
|
||||
**Note:** Adding extensions does not guarantee compatibility; FFmpeg must support the codec/container.
|
||||
|
||||
## Security Considerations
|
||||
|
||||
**Do NOT modify:**
|
||||
- Path validation logic
|
||||
- Command execution methods (must avoid `shell=True`)
|
||||
- Exception handling patterns
|
||||
|
||||
**Safe to modify:**
|
||||
- Numeric limits (file size, timeouts, dimensions)
|
||||
- Allowed file extensions (add formats supported by FFmpeg)
|
||||
- Output formatting preferences
|
||||
|
||||
**Unsafe modifications:**
|
||||
- Removing path sanitization
|
||||
- Bypassing file validation
|
||||
- Enabling shell command interpolation
|
||||
- Disabling resource limits

## PSNR (Peak Signal-to-Noise Ratio)
|
||||
|
||||
### Definition
|
||||
PSNR measures the ratio between the maximum possible power of a signal and the power of corrupting noise. It's commonly used to measure the quality of reconstruction of lossy compression codecs.
|
||||
|
||||
### Scale
|
||||
- **Range**: Typically 20-50 dB
|
||||
- **Higher is better**: More signal, less noise
|
||||
|
||||
### Quality Interpretation
|
||||
| PSNR (dB) | Quality Level | Use Case |
|
||||
|-----------|---------------|----------|
|
||||
| < 20 | Poor | Unacceptable for most applications |
|
||||
| 20-25 | Low | Acceptable for very low-bandwidth scenarios |
|
||||
| 25-30 | Fair | Basic video streaming |
|
||||
| 30-35 | Good | Standard streaming quality |
|
||||
| 35-40 | Very Good | High-quality streaming |
|
||||
| 40+ | Excellent | Near-lossless quality, archival |
|
||||
|
||||
### Calculation Formula
|
||||
```
|
||||
PSNR = 10 * log10(MAX_I^2 / MSE)
|
||||
```
|
||||
Where:
|
||||
- MAX_I = maximum pixel value (255 for 8-bit images)
|
||||
- MSE = mean squared error
|
||||
|
||||
## SSIM (Structural Similarity Index)
|
||||
|
||||
### Definition
|
||||
SSIM is a perceptual metric that quantifies image quality degradation based on structural information changes rather than pixel-level differences.
|
||||
|
||||
### Scale
|
||||
- **Range**: 0.0 to 1.0
|
||||
- **Higher is better**: More structural similarity
|
||||
|
||||
### Quality Interpretation
|
||||
| SSIM | Quality Level | Use Case |
|
||||
|------|---------------|----------|
|
||||
| < 0.70 | Poor | Visible artifacts, structural damage |
|
||||
| 0.70-0.80 | Fair | Noticeable quality loss |
|
||||
| 0.80-0.90 | Good | Acceptable for most streaming |
|
||||
| 0.90-0.95 | Very Good | High-quality streaming |
|
||||
| 0.95-0.98 | Excellent | Near-identical perception |
|
||||
| 0.98+ | Perfect | Indistinguishable from original |
|
||||
|
||||
### Components
|
||||
SSIM combines three comparisons:
|
||||
1. **Luminance**: Local brightness comparisons
|
||||
2. **Contrast**: Local contrast comparisons
|
||||
3. **Structure**: Local structure correlations
|
||||
|
||||
## VMAF (Video Multimethod Assessment Fusion)
|
||||
|
||||
### Definition
|
||||
VMAF is a machine learning-based metric that predicts subjective video quality by combining multiple quality metrics.
|
||||
|
||||
### Scale
|
||||
- **Range**: 0-100
|
||||
- **Higher is better**: Better perceived quality
|
||||
|
||||
### Quality Interpretation
|
||||
| VMAF | Quality Level | Use Case |
|
||||
|-------|---------------|----------|
|
||||
| < 20 | Poor | Unacceptable |
|
||||
| 20-40 | Low | Basic streaming |
|
||||
| 40-60 | Fair | Standard streaming |
|
||||
| 60-80 | Good | High-quality streaming |
|
||||
| 80-90 | Very Good | Premium streaming |
|
||||
| 90+ | Excellent | Reference quality |
|
||||
|
||||
## File Size and Bitrate Considerations
|
||||
|
||||
### Compression Targets by Use Case
|
||||
| Use Case | Size Reduction | PSNR Target | SSIM Target |
|
||||
|----------|----------------|-------------|-------------|
|
||||
| Social Media | 40-60% | 35-40 dB | 0.95-0.98 |
|
||||
| Streaming | 50-70% | 30-35 dB | 0.90-0.95 |
|
||||
| Archival | 20-40% | 40+ dB | 0.98+ |
|
||||
| Mobile | 60-80% | 25-30 dB | 0.85-0.90 |
|
||||
|
||||
### Bitrate Guidelines
|
||||
| Resolution | Target Bitrate (1080p equivalent) |
|
||||
|------------|-----------------------------------|
|
||||
| 480p | 1-2 Mbps |
|
||||
| 720p | 2-5 Mbps |
|
||||
| 1080p | 5-10 Mbps |
|
||||
| 4K | 20-50 Mbps |
