Captionate

Embedded subtitle export

Embed styled subtitles directly into your video.

Generate or translate a caption track, style it against a movie, interview, or video preview, and embed the open version permanently into an MP4. The subtitles become part of the video while the output keeps the original resolution.

From track to finished video

Embed subtitles into MP4 online from the same caption editor.

There is no separate burn-in project to rebuild. The caption version open in the editor, its timing, and its style settings are used together when Captionate renders the final video.

01

Preview before rendering

See the current caption text and appearance over the media player while you adjust the style.

02

Style for the frame

Control position, size, maximum width, text treatment, outline or background, and shadow.

03

Export the version you opened

The export flow clearly uses the caption currently open in the editor, including translated versions.

Three steps

Generate, style, and render captions onto video.

  1. Create or open captions

    Generate subtitles from the video or open the translated caption version you want to publish.

  2. Adjust the appearance

    Preview size, position, color, outline or background, width, and shadow against the video.

  3. Choose Video File

    Open Export, select Video File, and render an MP4 with the captions permanently visible.

Practical style control

Style and embed subtitles into video without leaving the project.

Captionate stores the appearance as an ASS-backed caption style. The browser preview and rendered output use the same settings, so the styling work remains portable when you export an ASS file, embed subtitles into video in original resolution, or create a captioned movie or interview.

  • Place captions on the frame. Choose a screen anchor and adjust the vertical offset.
  • Fit the available space. Change font size and maximum width for the source video.
  • Improve contrast. Use text color with either an outline or a semi-transparent background.
  • Finish the treatment. Add bold text, letter spacing, and a shadow preset where needed.

Adding subtitles to video.

How do I add subtitles directly to a video?

Upload a video, generate or translate captions, adjust the style, and choose Video File in Export. Captionate renders the open caption version into an MP4.

What are hardcoded subtitles?

Hardcoded subtitles are rendered into the video image. They remain visible even when a player or platform does not load a separate subtitle track.

Will the exported video keep its resolution?

Yes. The captioned MP4 is rendered at the original video resolution.

Which subtitle style settings can I change?

Adjust size, screen position, vertical offset, maximum width, text color, bold text, letter spacing, outline or background, and shadow.

Can I preview captions before rendering?

Yes. The editor displays the current caption version over the video while you make style changes.

Can I download only the subtitle file?

Yes. Choose Subtitle File in Export and download the open caption version as SRT, VTT, ASS, or TXT.

Can I add subtitles to a movie or interview video online?

Yes. Upload the movie or interview, generate or translate its captions, review the timing and style online, then export a captioned MP4.

Can I add an existing SRT or VTT file to a video?

Yes. Import the subtitle file, choose Upload media in the caption-only project, attach its matching video, and review the timing and style before exporting a captioned MP4.

Can I add subtitles to video online for free?

Sign up to receive free credits and test caption generation. The editor, subtitle styling preview, and subtitle file export are part of the same online workflow.

What should I look for in the best tool to add subtitles to video?
