Burning subtitles into a video creates a new video file where the subtitle text is part of the image. The subtitles stay visible wherever the video is shared, even if the platform does not show caption controls.
For the full public tool page, see Burn Subtitles Into Video. This help article explains the practical workflow inside Subtitling.net.
When to use this workflow
Use the burn subtitles workflow when you already have:
- a final video file
- an SRT subtitle file for that same video
- a need for subtitles that are always visible
This is useful for social clips, sales videos, training snippets, embedded videos, client deliveries, and files that will be shared outside a platform with reliable caption settings.
If you only have a video and do not have subtitles yet, start with the AI Subtitle Generator. It can generate subtitles first and also create a burned-in video.
What you need before uploading
Before you start, check that your video and SRT match each other.
- The SRT should belong to the final cut of the video.
- The subtitle timing should be correct.
- The SRT file should use UTF-8 text encoding.
- The file extension should be
.srt.
If the video was trimmed, re-exported, or edited after the SRT was created, the subtitles may be out of sync. Fix the SRT first in the free SRT editor or in your own subtitle editor.
Option 1: Use your own SRT file
If you already have a subtitle file, use the burn-only workflow.
- Open Burn Subtitles Into Video.
- Upload your video file.
- Upload your SRT file.
- Select the subtitle language.
- Create a free preview or render the full video.
The result is a new video file with permanent subtitles. Your original video and SRT file are not changed.
Option 2: Generate subtitles first, then burn them into the video
-
Upload your video.
Our AI generates subtitles and gives you both an SRT file and a video with burned-in subtitles. -
Edit if needed.
Open the SRT file in our free SRT editor or in any text editor. Save your changes. -
Upload the updated file.
Go to My Videos and upload the updated SRT file. We will render a revised version with burned-in subtitles at no extra charge.
Preview before rendering the full video
You can create a free preview before rendering the full video. Use the preview to check:
- whether the subtitle text is correct
- whether the SRT timing matches the video
- whether the selected language is correct
If something looks wrong, fix the SRT file first and preview again before rendering the full video.
Free re-renders after SRT edits
If you find a subtitle issue after rendering, correct the SRT file and render again. Re-renders are available at no extra cost for the same video, so you do not have to accept a permanent typo or timing mistake.
Use this flow:
- Download or open the SRT file.
- Correct the text or timing.
- Upload the updated SRT.
- Render the burned-in video again.
Multiple subtitle languages
Each language normally needs its own SRT file and its own rendered video. If you need three language versions, upload three SRT files and create a separate burned-in video for each language.
This is useful when you need separate deliverables for different audiences, platforms, or clients.
File limits and formats
The burn workflow supports common video formats including MP4, MOV, MKV, and WebM. Files can be up to 4 GB and up to 60 minutes long.
The subtitle file must be an SRT file. Other subtitle formats should be converted to SRT before uploading.
For more detail, see Supported video formats.
When not to burn subtitles in
Burned-in subtitles are permanent. Viewers cannot turn them off, resize them, or switch language tracks inside the same video file.
For long YouTube videos, online courses, or accessibility workflows where viewer control matters, a separate caption track may be better. Use burned-in subtitles when consistent visibility matters more than viewer control.
