Common Translation Issues

Tips for Better Auto-Translate Results

Choose Videos with Quality Captions

Look for these indicators:

• Creator-uploaded subtitles (shown in caption settings)
• Educational channels with professional production
• Official brand/company videos

Avoid:

• Videos with auto-generated captions on complex topics

• Content with lots of technical jargon

Check Source Language Options

Some videos have captions in multiple languages. Try:

1. 1.Settings → Subtitles → See all available languages
2. 2.If your language has native captions, use those instead
3. 3.If translating, translate from the highest quality source

Combine with Visual Context

Auto-translate works better when you:

• Watch the video (not just listen)
• Use visual cues to understand context
• Pause on confusing translations to figure out meaning

Adjust Playback Speed

• Slow down (0.75x) if translations are hard to read
• Gives more time to process translated text
• Helps with complex or technical content
