| Plain Text | .txt | Transcript without timing |

## SRT Format Reference

```
1
00:00:01,000 --> 00:00:04,000
This is the first subtitle line.

2
00:00:04,500 --> 00:00:08,000
This is the second subtitle line.
It can have multiple lines.

3
00:00:08,500 --> 00:00:12,000
And so on...
```

## Translation Guidelines

### Preserve Structure
```
ORIGINAL (English):
1
00:00:05,000 --> 00:00:08,500
Welcome to my channel!

TRANSLATED (Spanish):
1
00:00:05,000 --> 00:00:08,500
¡Bienvenidos a mi canal!

✅ Same timing, same number
✅ Natural translation (not word-for-word)
✅ Appropriate punctuation for target language
```

### Handle Line Length
```
PROBLEM: Translation is longer than original
SOLUTION: Split or abbreviate while keeping meaning

ORIGINAL:
1
00:00:10,000 --> 00:00:13,000
Click the subscribe button

GERMAN (longer):
1
00:00:10,000 --> 00:00:13,000
Klickt auf den
Abonnieren-Button

✅ Split into two lines if needed
✅ Keep within ~42 characters per line
✅ Maintain readability
```

### Cultural Adaptation
```
DON'T just translate - LOCALIZE:

Original: "That costs about 20 bucks"
Spanish (Latin America): "Eso cuesta unos 20 dólares"
Spanish (Spain): "Eso cuesta unos 20 euros"

Original: "Super Bowl Sunday"
French: "Le dimanche du Super Bowl" (keep cultural reference)
Chinese: "超级碗周日" (may need explanation)
```

## Quality Checklist

Before finalizing translation:

- [ ] Timing unchanged from original
- [ ] Line numbers sequential and correct
- [ ] No missing entries
- [ ] Line length readable (≤42 chars)
- [ ] Natural language (not robotic)
- [ ] Cultural references adapted
- [ ] Technical terms consistent
- [ ] Punctuation correct for target language
- [ ] Character encoding correct (UTF-8)
- [ ] Format valid (SRT/VTT structure)

## Common Issues & Solutions

| Issue | Cause | Solution |
|-------|-------|----------|
| Text overflow | Translation longer than original | Split lines, use abbreviations |
| Timing mismatch | Reading speed different | Adjust text length, not timing |
| Encoding errors | Wrong character set | Save as UTF-8 with BOM |
| Broken format | Extra line breaks | Validate SRT structure |
| Awkward phrasing | Literal translation | Localize for natural speech |

## Multi-Language Workflow

```
EFFICIENT BATCH PROCESS:

1. Get original transcript/SRT
2. Identify top languages for your audience:
   - Check YouTube Analytics for viewer locations
   - Common targets: ES, PT-BR, FR, DE, JA, KO, ZH

3. Translation priority order:
   Tier 1: Spanish, Portuguese (largest non-EN audiences)
   Tier 2: French, German (strong markets)
   Tier 3: Japanese, Korean (dedicated fandoms)
   Tier 4: Chinese, Hindi (massive populations)

4. Upload workflow:
   - YouTube: Add via Studio > Subtitles
   - Filename: videoname.[lang].srt (e.g., video.es.srt)
```

## Integration with YouTube

### Upload Subtitles
```
YouTube Studio > Video > Subtitles > Add Language

File types accepted:
- .srt (SubRip)
