How to put permanent captions on a video
Choose the matching video
Use the same edit that the subtitle timings were written against.
Add your SRT
Load the timed subtitle file and choose a caption size that fits the frame.
Render the captioned MP4
Check a long line and a fast exchange in the exported copy.
Give viewers captions wherever the video plays
Burned-in captions are useful when the destination accepts a video file but does not carry a separate subtitle track.
Send a client proof
Share one MP4 that displays the approved wording without asking the reviewer to load an SRT.
Prepare a kiosk loop
Bake instructions into the picture for a display that plays local video files.
Share a translated interview
Load your translated SRT and check that longer lines fit before handing off the export.
Subtitle burner FAQ
Can viewers switch the captions off afterward?
Burned captions become part of each frame. Play the result at phone size to check line breaks and keep the clean video and SRT for any future revisions.
Does this transcribe or translate speech?
No. Supply an SRT that already contains the words and their timings.
Can I change the caption size for portrait footage?
Yes. Set the font size before you burn the SRT file. Preview the exported clip at phone size and check long lines against the frame edges.
Will my SRT styling carry over?
The renderer uses white lettering with a dark outline near the bottom. It strips markup from the cue text.
What should a valid SRT timestamp look like?
Use a start and end time such as 00:00:01,000 --> 00:00:03,500, followed by the caption text on the next line. Separate cues with a blank line.
Where will the captions sit on the video?
Each caption is centred near the bottom with white lettering and a black outline. Check the sample against a busy shot before choosing the font size.
My captions all appear one second early. How can I fix them?
Shift the SRT forward by 1000 ms in the subtitle timing tool, then burn that corrected file into a fresh copy of the source video.
