AI Subtitle Translator

Translate an existing subtitle file into another language with Weydub, then inspect the wording, timestamps and line breaks before export. Start from SRT when you already have timed captions. If the words are only visible in the video or spoken in its audio, extract them with OCR or ASR first instead of treating the video as a subtitle file.

Translate a subtitle file or extract subtitles first?

SRT is the documented timed-subtitle path. File import controls also accept VTT; preview imported cues before translation. File acceptance alone does not guarantee every styling feature survives import or export.

Available inputNext stepBoundary
SRT subtitle fileImport timed cues and translate their text.Inspect numbering, encoding and timestamps.
VTT subtitle fileImport through a supported file control and inspect the parsed cues.Verify cue compatibility; do not assume styling round-trips.
Video with burned-in subtitlesExtract visible text with OCR first.This is not direct subtitle-file translation.
Audio without captionsGenerate timed text with ASR first.Review the transcript before translating it.

Keep the meaning and the time window together

Translation can become longer than the source. Keeping a timestamp does not by itself make the translated line readable.

Frequently Asked Questions

  • Why use Weydub instead of direct LLM subtitle translation?

    Weydub connects subtitle translation with file handling, task tracking and online review. Compare source and target text and inspect the exported cues. Choose the workflow that fits your file format and review needs; translation quality still depends on the source and your final checks.
  • Do I need an account to translate subtitles?

    Sign in to access the subtitle workspace and see the modes available to your account. Free and Agent options may differ by workflow. Check the selected mode, task limits and displayed cost before submitting.
  • How is subtitle translation priced, and is there a free option?

    A free mode is available in supported subtitle translation workflows. Agent translation and other AI tasks may have separate costs. Check the selected mode and the price shown before submission; free subtitle translation does not make generation, dubbing or video rendering free.
  • How long does translation take?

    Completion time depends on file length, batch size, selected mode and current service load. Follow progress in the workspace and allow time to review the translated text before export. There is no single completion time for every task.
  • Are video subtitles stored on your servers? Are they kept private?

    Subtitle processing requires sending your file content to the service. Review the linked Privacy Policy and current account settings for data handling and retention details. Confirm that you are authorized to upload the material and that the terms meet any confidentiality requirements.
  • Does free mode mean every translation workflow is unlimited?

    No. Free mode does not imply unlimited access to every AI workflow. Language options, batch limits and availability can differ by mode and account. Check the current workspace settings and any displayed cost before starting a task.
  • Can you translate embedded (hardcoded) subtitles without an SRT file?

    Use OCR to extract visible subtitles into a timed text draft, correct recognition errors and translate the file. This produces translated subtitle text; removing or replacing the original burned-in text requires separate video processing and a preview of the rendered result.
  • What should I compare when choosing an AI subtitle translator?

    Check supported formats and languages, source-versus-target review, timestamp handling, batch limits and export options. Test a short file containing names, specialist terms and fast dialogue. Compare both the translated meaning and the exported timing before choosing a workflow.
  • What's an automatic subtitle translator and how does it work?

    An automatic subtitle translator translates the text in subtitle cues for a target language. If you only have audio, generate a draft with ASR first; if text is burned into video frames, extract it with OCR. Review that draft before translation and check timing again after export.
  • How accurate is Weydub's automatic subtitle translation?

    Accuracy varies with source quality, language pair, terminology and context. Compare the translated text with the source and have a fluent reviewer check names, numbers, tone and ambiguous lines. Preview timing and line breaks separately from the language review.
  • What languages does your automatic subtitle translator support?

    Open the target-language list in the selected mode to confirm current support. Options for subtitle translation, speech recognition, OCR and dubbing are not necessarily the same. Check both the input workflow and target language before submitting.
  • Can I edit the automatically translated subtitles?

    Yes. Review and edit translated wording and subtitle timing in the available editor. Check repeated terminology and line breaks before export. An SRT file stores text and timestamps; fonts, colors and positioning are configured in the playback or video composition tool.
  • Can I download the translated subtitle file?

    Use the download options shown for the completed task and check which subtitle formats are available. Preview the exported file in your destination player, including text encoding, timestamps and line breaks. A subtitle-file download is separate from rendering captions into a video.
