Frequently Asked Questions
Is there a fee to use this tool?
This tool requires you to provide your own API key and charges based on actual API usage. We don't charge additional service fees, giving you complete control over costs. For large-volume usage, we recommend setting reasonable API usage limits to control budget expenditure. GPT-4o-mini offers the best value for money.
Which subtitle formats are supported?
Currently, we only support the SRT subtitle format with automatic file encoding detection and proper handling. We plan to support more professional subtitle formats such as ASS, SSA, and LRC in future versions, as well as automatic detection and extraction of embedded subtitles. For non-standard formats, you can convert them using third-party tools before importing.
How can I improve translation quality?
Using smaller batch sizes and lower creativity settings can improve translation accuracy, while enabling translation memory helps maintain contextual coherence. We recommend reasonable use of translation memory and professional terminology lists, which help AI better understand content context and generate professional, high-quality translations.
Will subtitle timelines be affected?
Not at all. Our translation process only replaces subtitle text content, and all timeline information is completely preserved. You can confidently apply the translated subtitle file directly to the original video without any timeline adjustments. If you need to fine-tune either the original or translated subtitles, you can edit them in the operations column by sliding the table.
What does batch processing mean?
Batch translation divides the subtitle file into multiple batches according to your batch size setting, allowing you to get translation results faster and save API usage. Don't worry about model hallucinations; our backend algorithms automatically optimize translation results, performing intelligent matching or retranslation when necessary to ensure translation quality.
How do I export the translated subtitles?
After translation is complete, the system automatically provides download options with multiple export styles. You can choose to keep only the translated text or generate bilingual subtitle files. For precise proofreading, you can export translation memory and use the translation memory feature for one-to-one accurate proofreading.
