Step-by-Step Guide
Prepare Your Subtitle File
Ensure your subtitle file is in the correct format (SRT, ASS, or VTT). Check that:
- • The file has proper timing information
- • Text encoding is UTF-8 (for Asian characters)
- • The file size is under 10MB
- • There are no formatting errors
Visit DramaSub

Upload Your File
Drag and drop your subtitle file or click to browse. The file will be uploaded to our secure servers for processing. Wait for the upload to complete before proceeding.
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
Example: WebVTT header preservation - "WEBVTT" must remain as first line with no blank lines before it
Example: Cue settings - "00:00:01.000 --> 00:00:04.000 line:80%" maintains vertical positioning during translation
Example: CSS styling - "<c.colorClass>text</c> preserves inline styling while translating content
Example: Timestamp format - VTT uses HH:MM:SS.mmm different from SRT's comma separator
Expert Tips
VTT requires "WEBVTT" as the very first line - never modify or remove this header
Timestamp format uses periods (.) instead of commas (,) for milliseconds - unlike SRT format
VTT supports CSS classes - maintain class names when translating styled text
Blank lines separate cues - preserve empty lines between subtitle entries
Use Chrome DevTools or online validators to test VTT files for web compatibility
Common Mistakes to Avoid
Removing the required "WEBVTT" header which renders the entire file invalid
Using comma separators for timestamps instead of VTT's required period format
Deleting cue settings like position or line alignments that control text placement
Not escaping special characters like & < > which break HTML rendering
Converting VTT to SRT for editing and back - this loses VTT-specific features
