Text that remains visible in the MP4
Burned-in captions travel with the picture. They do not depend on Facebook loading a separate subtitle track, and viewers cannot toggle them off in the file.

How to add captions to a Facebook Reel
Open the short video
Paste a public Facebook reel or video URL and import it in Creator Studio, or upload your local recording. The source limit is 180 seconds and 100 MB.
Add or generate the subtitle lines
Import an SRT, type captions manually or generate them from speech when available. Review each line, adjust start and end seconds and choose a caption style.
Burn captions into the export
Enable Burn subtitles into video and export the MP4. Inspect the processed preview for text placement. Download SRT too if you want an editable copy of the captions.
Captions you can change line by line
Correct the words before publishing
Edit names, punctuation or mistranscribed phrases. Importing your own SRT and manually adding lines are available even when automatic recognition is unavailable.
Add a label at the right time
Use the Timed inserts panel for a brief note or label that was not spoken. Its times refer to the finished video, while source captions follow your cuts.
Before you start
The current editor accepts videos up to 180 seconds and 100 MB. Cloud imports, AI processing and exports require sign-in. Portrait video exports use a 720 × 1280 canvas. Only upload material that can be public: the editor uses a public asset bucket.
Frequently asked questions
Are captions and subtitles both supported?
You can add timed text for spoken dialogue and extra notes. If you need another language, translate the subtitle text in the editor before export.
Will the subtitles appear in the downloaded reel?
Yes, when subtitle burning is enabled. SRT can also be downloaded separately, but downloading only SRT does not add visible text to the MP4.
Do I have to use automatic captions?
No. Type your own captions or import an SRT up to 128 KB. You can edit every line and its timing without speech recognition.
Can I edit the captions of an existing Facebook post?
This creates a new captioned video or SRT file. It does not change a published Facebook post. Cloud processing requires sign-in; use a file upload if Facebook prevents importing your public link.
