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:

• Line numbers sequential and correct
• No missing entries
• Line length readable (≤42 chars)

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
