Human Review Recommendations

When to review translations manually:

Cultural Adaptation

Good translation goes beyond word-for-word:

Consider adapting:

  • Dates: MM/DD/YYYY vs DD/MM/YYYY
  • Names: Western vs Eastern name order
  • Examples: Use locally relevant examples
  • Humor: Adapt jokes that don’t translate literally
  • Colors/symbols: Cultural color meanings differ

Example adaptation:

  • Original (US): “It’s as American as apple pie”
  • Spanish: “Es tan español como la tortilla de patatas”
  • Adaptation preserves meaning, changes cultural reference

Troubleshooting Common Issues

”Translation doesn’t make sense”

Causes:

  • AI misunderstood context
  • Idioms translated literally
  • Technical terms not recognized
  • Poor original transcription

Solutions:

  1. Edit transcript in original language first (ensure accuracy)
  2. Use translation editor to fix context issues
  3. Add glossary for technical terms (if available)
  4. For critical content, get human review

”Dubbing doesn’t sync with video”

Causes:

  • Different language word counts
  • Speaking pace differences
  • Translation longer/shorter than original

Solutions:

  1. Adjust translation to match original duration
  2. Use dubbing speed controls (slow down or speed up)
  3. Re-generate specific segments
  4. Use subtitles instead for precision timing

”Voice sounds unnatural”

Causes:

  • Wrong voice selection for content
  • Language accent mismatch
  • Monotone delivery

Solutions:

  1. Try different voice from voice library
  2. Adjust voice parameters (tone, pitch, speed)
  3. For critical content, consider human voiceover
  4. Split into smaller segments and vary voices

”Subtitles too long/short”

Causes:

  • Target language more/less verbose than source
  • Reading speed differences by language

Solutions:

  1. Edit translation for conciseness
  2. Split long subtitles into multiple lines
  3. Adjust display time per subtitle
  4. Use abbreviations where culturally appropriate

Best Practices for Video Translation

Before Translating

Prepare your source video:

  1. Ensure clear audio (no background noise)
  2. Speak clearly and at moderate pace
  3. Avoid rapid-fire speech or mumbling
  4. Use simple sentence structures (easier to translate)
  5. Minimize cultural idioms in original (or plan adaptations)

During Translation

Optimize translation workflow:

  1. Translate to most important markets first (Spanish, Chinese, French)
  2. Review high-priority languages manually
  3. Use glossaries for consistent terminology
  4. Keep sentence structure simple when possible
  5. Preserve brand names and product terms

After Translation

Quality assurance checklist:

  • Watch full video in each language
  • Check subtitle timing and readability
  • Verify voiceover sync (if dubbed)
  • Test on target platform (YouTube, website, etc.)
  • Get native speaker review (if business-critical)
  • Ensure exported files named correctly

Ongoing Management
