How to translate subtitles on an X (Twitter) video
For a video in an X post, first decide whether you want to understand it on the page or keep an output file. WatchTranslate uses readable native captions when available, or generates text from accessible video audio. It does not require every X video to have captions, and it cannot promise that every source is readable.
Find the video and select its subtitle source
Open the original X post with the video you want, rather than a screenshot, a quoted still image or an unrelated embedded player. Install and enable the desktop extension, sign in and allow the page to load the actual video.
If the subtitle source selector offers a native caption track, select it to translate existing text. Otherwise choose audio recognition. Automatic source-language detection is available for speech; a known original language can help when detection is unsuitable. Choose the target language separately.
Start translation on the actual X player
- Keep the original post open and select the correct video if the page contains several media items.
- Choose the subtitle source and target language. For audio recognition, use automatic detection or select the original language when needed.
- Click Start translation, then play the video. Choosing a target language alone does not start a job.
- Use original, translated or bilingual display. Pause on a spoken moment to check the text; visual styling does not change recognized words.
Processing follows 30-second windows around playback. On the audio path, the needed audio segments are sent for recognition and translation; on the track path, subtitle text is processed. Neither workflow means all of the clip has already been prepared.
What to check when a clip has no translated text
- Native captions exist but cannot be read: check the selected source and the displayed error, then choose audio recognition deliberately if appropriate.
- The video does not play or audio access fails: verify access to the original post and try its available source. The extension does not bypass private, deleted or restricted media.
- There is no speech: music and silent footage may have nothing to subtitle.
- Words are wrong: listen for overlapping speakers, noise or an unsuitable source language; generated subtitles need review.
- You navigated to another post: verify the current video and source. The previous video’s captions are not evidence for the new one.

Save text subtitles or a burned-in video
For a separate subtitle file, choose SRT or VTT and original, translated or bilingual content. Review generated coverage and the quote, confirm when required, then download. The file contains text and timestamps, not the X video.
The desktop beta video export reads the selected actual MP4 source and burns the chosen subtitles/style into an MP4. Keep the original page open and inspect source quality, output size and coverage. A larger output resolution cannot create detail absent from the source.
To keep subtitles throughout a clip, complete the supported full-video preparation first and check for remaining windows. Exporting or sharing never generates missing subtitles by itself.
- Choose between SRT/VTT and an MP4 with subtitles
- Inspect a self-authored local input and illustrative subtitle files
Sharing a link is another separate action
A public subtitle share exposes the video’s share metadata in the subtitle catalogue and can be indexed by search engines. It is not a private download, a copy of the original video, or proof of complete subtitle coverage. Review the current completion state and public-sharing warning before choosing it.
FAQ
Do X videos need native captions?
No, the supported audio path can generate text from speech when a native track is unavailable. Audio and source access still need to work.
Can I export bilingual subtitles?
Yes. Select bilingual content for SRT/VTT or the supported video export. Check that generated cues contain the needed source and translation text.
Why are there gaps in my downloaded subtitles?
Only generated content is included. Quiet sections may contain no speech, and unprocessed or failed windows need to be distinguished from completed empty windows.
Is an MP4 export the same as an SRT download?
No. SRT/VTT are text files; video export produces an MP4 with selected subtitles burned into the picture and has additional browser/source/resource requirements.
