Export an SRT for the exact video you will publish, review the text and timing, then add it through the destination’s caption controls. YouTube, Facebook, Vimeo and LinkedIn document subtitle-file workflows, though their controls differ. Uploading the caption file is a separate step from exporting it on your iPhone.
What should you check before uploading?
Keep the video and captions together in a clearly named folder. An SRT for a rough cut will not necessarily match the finished edit. Check names, numbers and the first and last spoken lines before uploading either file.
Transcribe Audio to Text can transcribe a local video’s audio and export SRT from Captions after you review the transcript. It does not publish to social platforms. Transfer the caption file and original video to the computer you use for publication.
Where do you add the file in YouTube Studio?
In YouTube Studio, open Subtitles, select the video and choose or add its language. Use Add under Subtitles, then Upload file > With timing > Continue. Select your SRT and save.
Preview a line near the start and one near the end. If you publish a different cut, check the captions for that cut again; a changed opening or removed passage can shift the timing.
YouTube can also generate automatic captions. Review any available result in Studio before relying on it; this is YouTube’s own recognition, separate from importing an SRT.
To retrieve captions from your own video, use Studio > Subtitles, open Edit for the language, then Options > Download subtitles. Keep the downloaded format unchanged until you know which editor will use it.
How does the Facebook upload work?
For a profile video on a computer, Facebook documents Edit post > Edit > Add captions, followed by uploading the SRT and saving. Its help also links to filename conventions.
Use the caption controls for the kind of post you are editing. A normal video’s instructions should not be assumed to apply to every Reel, Story or mobile composer. Check any filename or language error before changing the caption text.
Where are the controls in Vimeo and LinkedIn?
In Vimeo, open your Library video and choose Languages > +. Select the file and its language and type, click Upload, then activate the track. Check the video with captions enabled.
For LinkedIn’s documented desktop route, add your video, open Edit in the preview and use Select Caption to attach SRT before posting. Keep your reviewed file even after the upload succeeds.
How do you know the published captions work?
Open the finished video as a viewer. Enable captions and check the selected language, accents, line breaks and synchronization at several points. A successful upload only confirms that a file was accepted.
Keep each language in its own reviewed file. Choosing a different language label does not translate the words. If you need permanent text in the picture rather than a switchable caption track, make that version in your video editor before uploading.
Questions you may have
Does exporting SRT automatically publish captions?
No. Export produces a file. You still attach it to the video using the destination’s caption controls and save or publish there.
Can I use the same SRT on every platform?
The same reviewed timing and text may be reusable, but check each platform’s format, naming and language requirements before uploading.
Why are no captions visible after uploading?
Check that processing has finished, the track was saved and enabled, and the viewer has selected captions in the correct language.
Does choosing a language translate the SRT?
No. That setting identifies the language already in the file. Prepare and review a separate translation if you need another language.
