Subtitles for creators and social video

Choose a language for an actual audience

Start with viewer requests and the languages you can review. Audience geography can suggest a question to investigate, but a country is not a language preference. Ask which version would help and begin with one. Translated subtitles make the words available in another language; they do not guarantee recommendations, more views or sales.

Same-language captions and translated subtitles serve different needs. For a version in the spoken language, choose that language as the target. For a translated version, select the language your intended viewers read. Vid Hub keeps the original audio; it does not dub a new voice.

A repeatable workflow for each language

1. Start with your original video

   Upload a video you own or have permission to process. Use the clean source before adding subtitles, so existing burned-in text does not compete with the new version.

2. Generate one target version

   Choose the target language and run the job. Each job transcribes the audio again. Corrections in one job do not carry into another language, so plan review time for every version.

3. Check meaning and timing

   Compare names, numbers and key phrases with the audio. Ask someone who understands the target language to check the meaning. On Pro and Studio, edit wording and timing in Vid Hub and reburn the MP4 after changes.

4. Publish the right file

   Download the MP4 for text that is always visible, or the SRT for a destination that accepts a caption track. Upload the files to your publishing platform yourself and preview the result there.

SRT or burned-in subtitles?

A burned-in MP4 carries its subtitles as part of the picture. A separate SRT lets a compatible player display a caption track, which viewers may be able to turn on or off. X documents SRT upload on the web; other destinations have their own file and player requirements. Check the current publishing controls before choosing. See burned-in versus soft subtitles.

Editing a downloaded SRT does not change an MP4 you already exported. Use the reviewed SRT with the matching source video, or reburn the revised subtitles with Pro or Studio before downloading a new MP4. Recheck timing if you trim or otherwise change the video after generating subtitles.

Review on the screen viewers will use

• Watch the published preview on a phone, with and without sound. Check that platform buttons and your own graphics do not cover the text.
• Read the longest cue at normal playback speed. Shorten wording carefully when the translation cannot be read in time; use timing and reading speed for review guidance.
• Automatic speech transcription is a starting point. Check any meaningful sounds or speaker changes a viewer needs; generated subtitles alone are not a reviewed accessibility caption track.
• Keep the original and translated SRT and TXT downloads with the source video. TXT is useful for reviewing wording, but it has no subtitle timing.
