# Batch Processing Guide

## Overview

This guide covers how to process entire folders of adaptation videos and generate comprehensive HTML reports.

**Last Updated:** January 2025 (Tested & Verified)

---

## 🚀 Quick Start

### Process a Folder of Videos

```bash
# Fast mode (recommended for same-aspect videos)
python batch_match_fast.py /path/to/adaptations/ report.html

# Full mode (with AKAZE verification)
python cli.py batch-match /path/to/adaptations/ -o report.html
```

---

## 📋 Prerequisites

### 1. Add Master Videos First

Before batch processing, ensure your master videos are registered:

```bash
# Bulk add all masters from folder
python bulk_add_masters.py /path/to/masters/ -r

# Verify masters are loaded
python cli.py list-masters
```

**Expected output:**
```
Master Videos
╭──────────┬───────────┬──────────┬──────╮
│ ID       │ Filename  │ Duration │ Path │
├──────────┼───────────┼──────────┼──────┤
│ master_1 │ video.mp4 │ 20.0s    │ ...  │
│ ...      │ ...       │ ...      │ ...  │
╰──────────┴───────────┴──────────┴──────╯

✓ 46 masters registered
```

## ⚡ Batch Processing Modes

### Mode 1: Fast Batch (Recommended)

**Use when:**
- Same aspect ratio videos (1x1, 9x16, 16x9 → same format)
- Quick results needed
- High confidence in perceptual hash accuracy

**Command:**
```bash
python batch_match_fast.py /path/to/adaptations/ output_report.html
```

**Features:**
- ✅ Perceptual hash matching (fast)
- ✅ Metadata filtering (if filenames follow conventions)
- ✅ AI Vision fallback (if no matches)
- ❌ AKAZE verification (skipped for speed)

**Performance:**
- ~8-12 seconds per video
- **Example:** 39 videos in 5-8 minutes

---

### Mode 2: Full Batch (Most Accurate)

**Use when:**
- Cross-aspect ratio videos (16:9 → 1x1 → 9:16)
- Final validation needed
- Audit trail required
- Extra verification desired

**Command:**
```bash
python cli.py batch-match /path/to/adaptations/ -o output_report.html
```

**Features:**
- ✅ Perceptual hash pre-filtering
- ✅ AKAZE verification (top 5 candidates)
- ✅ Metadata filtering
- ✅ AI Vision fallback

**Performance:**
- ~15-25 seconds per video
- **Example:** 39 videos in 10-15 minutes

## 🎯 Real-World Example

### Test Case: Austrian Spring Fashion Campaign

**Setup:**
```bash
# Masters: 46 videos (various formats, variants, durations)
python bulk_add_masters.py /path/to/masters/ -r

# Adaptations: 39 videos (German language, Austrian market)
python batch_match_fast.py "/path/to/AT/" AT_report.html
```

**Results:**
```
Processing Time: 6 minutes 42 seconds

Summary:
  Total adaptations: 39
  Matched: 39
  No matches: 0
  Total master matches: 39

Method Breakdown:
  Perceptual Hash: 39 (100%)
  AKAZE: 0 (not run in fast mode)
  AI Vision: 0 (not needed)

Average match confidence: 95.2%
```

**Findings:**
- ✅ All 39 adaptations matched successfully
- ✅ 100% match rates (12/12 frames)
- ✅ Different languages handled perfectly
- ✅ Logo/text differences ignored
- ✅ Correct master identification (longest duration ranked #1)

---

## 🔧 Advanced Options

### Custom Thresholds

```bash
# Adjust matching thresholds
python cli.py batch-match /path/to/folder/ \
  -t 0.80 \   # Match threshold (80%)
  -f 0.80 \   # Frame similarity
  -m 0.90 \   # Min average similarity
  -o report.html
```

**When to adjust:**
- `-t` (threshold): Lower for fuzzy matching, higher for strict
- `-f` (frame threshold): Lower for heavily edited videos
- `-m` (min avg similarity): Lower for degraded quality videos

### Process Multiple Folders

```bash
# Process by market
python batch_match_fast.py /path/to/AT/ AT_report.html
python batch_match_fast.py /path/to/DE/ DE_report.html
python batch_match_fast.py /path/to/FR/ FR_report.html
python batch_match_fast.py /path/to/UK/ UK_report.html

# Process by format
python batch_match_fast.py /path/to/1x1/ square_report.html
python batch_match_fast.py /path/to/9x16/ vertical_report.html
python batch_match_fast.py /path/to/16x9/ landscape_report.html
```

## 📈 Performance Guidelines

### Processing Time Estimates

| Video Count | Fast Mode | Full Mode |
|-------------|-----------|-----------|
| 10 | 2 min | 3-4 min |
| 25 | 4-5 min | 7-10 min |
| 50 | 8-10 min | 15-20 min |
| 100 | 15-20 min | 30-40 min |
| 500 | 80-100 min | 150-200 min |

**Variables affecting speed:**
- Video duration (longer = more frames)
- Number of masters in library
- CPU speed
- Disk I/O speed

### Memory Requirements

- **Small batch (<50 videos):** 2-4 GB RAM
- **Medium batch (50-200 videos):** 4-8 GB RAM
- **Large batch (>200 videos):** 8+ GB RAM

### Disk Space

- Fingerprint cache: ~20 KB per video
- **Example:** 500 videos = ~10 MB cache
- Reports: ~500 KB - 2 MB per report

---

## 🔍 Troubleshooting

### Issue: Processing Hangs

**Symptom:** Processing stops or hangs on a video

**Solution:**
1. Check if video file is corrupted:
   ```bash
   ffmpeg -v error -i problem_video.mp4 -f null -
   ```

2. Skip problematic videos:
   ```bash
   # Move to separate folder and process later
   mv problem_video.mp4 ../problems/
   ```

3. Use faster mode:
   ```bash
   python batch_match_fast.py /path/to/folder/ report.html
   ```

---

### Issue: No Matches Found

**Symptom:** All or most videos show "No matches"

**Causes & Solutions:**

1. **Masters not registered:**
   ```bash
   python cli.py list-masters
   # If empty, add masters first
   python bulk_add_masters.py /path/to/masters/ -r
   ```

2. **Thresholds too strict:**
   ```bash
   # Lower thresholds
   python cli.py batch-match /path/to/folder/ -t 0.70 -f 0.75 -m 0.85
   ```

3. **Cross-aspect ratio videos:**
   ```bash
   # Use full mode with AI Vision
   python cli.py batch-match /path/to/folder/ -o report.html
   # AI Vision will automatically trigger
   ```

4. **Different content:**
   ```bash
   # Verify manually that adaptations are from your masters
   # May need different master library
   ```

---

### Issue: Slow Processing

**Symptom:** Takes much longer than expected

**Solutions:**

1. **Use fast mode:**
   ```bash
   python batch_match_fast.py /path/to/folder/ report.html
   # 2x faster than full mode
   ```

2. **Check fingerprint cache:**
   ```bash
   ls -lh data/fingerprints/
   # Should have fingerprints for all masters
   # If missing, run: python bulk_add_masters.py /path/to/masters/ -r
   ```

3. **Reduce metadata filtering overhead:**
   ```python
   # Edit matcher.py or use fast mode which handles this
   ```

---

## 💡 Best Practices

### 1. Filename Conventions

For best metadata filtering results, use consistent naming:

**Good:**
```
Product_16x9_A_15s.mp4
Product_1x1_B_10s.mp4
Campaign_9x16_C_6s.mp4
```

**Less Ideal:**
```
video1.mp4
final_cut_v2.mp4
master_backup.mp4
```

**Metadata extraction looks for:**
- Format: `1x1`, `9x16`, `16x9`, `4x3`
- Variant: `A`, `B`, `C`, `D`, `E`, `F`
- Duration: `6s`, `10s`, `15s`, `20s`

### 2. Master Organization

Organize masters by campaign:
```
masters/
├── spring_2024/
│   ├── master_1x1_A_6s.mp4
│   ├── master_1x1_A_10s.mp4
│   └── master_1x1_A_15s.mp4
├── summer_2024/
│   └── ...
└── fall_2024/
    └── ...
```

### 3. Adaptation Organization

Organize adaptations by market/format:
```
adaptations/
├── AT/  # Austria
├── DE/  # Germany
├── FR/  # France
└── UK/  # United Kingdom
```

Or by format:
```
adaptations/
├── 1x1/   # Square
├── 9x16/  # Vertical
└── 16x9/  # Landscape
```

### 4. Report Naming

Use descriptive report names:
```bash
# Good
python batch_match_fast.py AT/ AT_Spring2024_$(date +%Y%m%d).html
python batch_match_fast.py DE/ DE_Spring2024_$(date +%Y%m%d).html

# Descriptive with timestamp
python batch_match_fast.py AT/ AT_Spring_20240126.html
```

# 3. Export results if needed
# (Report is self-contained HTML)
```

### Quality Assurance Workflow

```bash
# 1. Fast pass for bulk checking
python batch_match_fast.py /batch1/ quick_check.html

# 2. Full pass for final validation
python cli.py batch-match /batch1/ -o final_validation.html

# 3. Compare results
# Both reports should show same matches
# Full pass shows AKAZE verification
```

### Multi-Market Workflow

```bash
# Process each market separately
for market in AT DE FR UK ES IT; do
  python batch_match_fast.py "/markets/$market/" "${market}_report.html"
done

# Consolidate results
# Each market gets its own report for review
```
