What to do when a YouTube video has no captions
Missing captions and captions in the wrong language are different problems. A visible caption track can be translated; a video without a usable track needs speech recognition. Check YouTube’s own options first, then choose the appropriate WatchTranslate source instead of assuming every missing CC control means the same thing.
Check YouTube’s captions before generating new text
- Open the original video page on youtube.com. Check Subtitles/CC in the player settings for uploaded or automatic tracks.
- If a track exists, try enabling it and, when offered, YouTube’s Auto-translate option for your target language.
- If available, Show transcript is useful for reading or copying words; it is different from a downloadable subtitle file or burned-in video.
- If no usable track is offered, consider audio recognition. Recheck a recently uploaded video later if waiting for YouTube’s captions suits your needs.
Why automatic captions may be absent
YouTube’s help lists delayed processing, unsupported language, poor or unrecognized speech, overlapping speakers, long initial silence and video length among possible causes. The absence of a caption option alone does not identify which cause applies. Automatic captions can also contain errors and need review.
Translate a track, or generate subtitles from audio
- Install the WatchTranslate desktop browser extension, sign in and keep the original YouTube video page open.
- Choose the target language. In the subtitle source selector, use an available native track to translate its text, or audio recognition when there is no usable track.
- For audio recognition, use automatic source-language detection or select the original language when needed. Click Start translation, then play a spoken section.
- Switch original, translated or bilingual display and check the words against the audio before continuing.
The default source selection uses an available track and otherwise the audio path. An explicitly selected track that fails to load can show an error: check the source rather than expecting an invisible fallback. Audio processing uses 30-second windows; it does not upload the whole video.
Troubleshoot the source, not only the language menu
- No controls after installation: reload the original page and confirm the extension is enabled; an embedded player is a different context.
- Track cannot be read: check that the selected track still exists and retry, or deliberately choose audio recognition.
- Audio cannot be read or the video is restricted: follow the error; this is not a way to bypass platform access restrictions.
- Quiet or music-only section: speech recognition may have no words to return. Noisy speech can still produce inaccurate text.
- Live video or a mobile browser: this desktop VOD extension workflow does not promise live-stream or mobile-extension support.
Transcript, subtitle download and video export are different
A transcript helps you read words. SRT/VTT keep generated subtitle text with timestamps; choose original, translation or bilingual output and review coverage and the quote. Watching a short section does not prepare the rest of the video.
For a whole-video result, use the supported full-video preparation control and check completion before export. The desktop beta MP4 video export burns selected text/style into the picture, uses the selected actual source quality, and requires the original page to remain open. Downloading subtitles or exporting does not fill missing windows.

FAQ
Can WatchTranslate work without a YouTube caption track?
For a supported accessible VOD, the audio-recognition path can generate and translate text from speech. Readability and success depend on the actual audio and source access; a missing track is not a guarantee of success.
Does YouTube Auto-translate create captions from uncaptured audio?
Use it when YouTube offers a caption track. If no usable track is available, generating text from audio is a separate step.
Do I have to download the video first?
No for this in-page workflow. Keep the original page open. If you already have a permitted local file, use Local Player instead.
Can I save only the part I have watched?
Generated subtitle content can be exported, subject to the displayed coverage and quote. Unprocessed sections remain missing; the MP4 export can contain the whole video with subtitles only in generated sections.
