Download Translation
Once processing is complete, download your translated subtitle file. The translated file will have the same format and timing as your original file, with all text translated to English.
Test and Adjust
Load your translated subtitles with your video and check for accuracy. Make minor adjustments if needed. For best results, provide context about your content when uploading.
Pro Tips
🎯 Context Matters
Always provide a brief synopsis of your content. This helps our AI understand the context and provide more accurate translations, especially for cultural references and idioms.
⚡ Start Small
When starting with a new series, translate a few episodes first to check quality and accuracy before batch processing the entire season.
🔍 Check Encoding
Ensure your source files use UTF-8 encoding. This prevents character display issues with Japanese, Korean, and Chinese text.
💾 Keep Backups
Always keep backup copies of your original subtitle files before translation. This allows you to compare and revert if needed.

❌ Ignoring File Encoding
Not checking file encoding can lead to garbled text. Always verify UTF-8 encoding for Asian language files.
❌ Skipping Context
Failing to provide content context can result in literal translations that miss cultural nuances and meaning.
❌ Not Testing First
Translating entire series without testing can waste time if adjustments are needed. Always test with a sample first.
Practical Examples
Good break at phrase boundary — "I went to the store / to buy some milk" reads naturally across two lines
Bad break mid-phrase — "I went to the store to buy / some milk" splits the verb phrase awkwardly
Good break preserving names — "Kim Soo-hyun looked at / the letter in his hands" keeps the full name on one line
Bad break splitting a name — "Kim Soo- / hyun looked at the letter" breaks the name across lines, confusing readers
Expert Tips
Maximum 2 lines per subtitle — 3+ lines covers too much screen and overwhelms readers
Aim for 37-42 characters per line — this is the industry standard for readable subtitles
Break at natural phrase boundaries — after commas, conjunctions, or complete clauses
Never break a person's name across lines — keep full names intact on one line
Keep articles with their nouns — "the house" should stay together, not split as "the / house"
Common Mistakes to Avoid
Breaking lines at exact character counts without considering word boundaries — always break at phrase boundaries
Allowing 3+ line subtitles — viewers cannot read that fast and it blocks the video
Splitting proper names, honorifics, or verb phrases across lines
AI-translated subtitles often have poor line breaks — always review and fix line breaks after translation
Forgetting that line breaks affect reading speed — poor breaks force re-reading and slow comprehension
Frequently Asked Questions
Why do my subtitles have too many lines?
Subtitles with 3+ lines are usually caused by: auto-translation that produces longer text than the original, missing line break rules, or text that was not formatted for subtitle display. Keep subtitles to 2 lines maximum with 37-42 characters per line.
What are the subtitle line break best practices?
Break at natural phrase boundaries (after commas, conjunctions). Keep proper names on one line. Maximum 2 lines per subtitle. Aim for 37-42 characters per line. Never break mid-word or split verb phrases across lines.
How to fix subtitle text wrapping issues?
Manually insert line breaks at natural reading points in your subtitle file. For SRT files, add a line break between the two lines of text. Ensure each line stays under 42 characters. Use DramaSub to translate with properly formatted output.
What font size and style is best for subtitles?
Sans-serif fonts (Arial, Helvetica, Verdana) at a readable size are the standard. White text with a black outline on a semi-transparent background provides the best readability across all video content.
