Auto-Subtitle Generator

Kapwing's AI Subtitle Generator provides an editable and downloadable transcript alongside your auto-generated subtitles. Generate or upload your subtitles, then click the download icon above the subtitle editor. You can download subtitles as an SRT or VTT file for use on video platforms and media players like Facebook and X (Twitter), or as a TXT file if you only need the transcript.

You can also export the entire video with the subtitles hardcoded, adding SRT to MP4 so the text remains visible wherever the video is uploaded or played.

Kapwing provides an in-built video translator that can translate to and from over 100+ different languages, including English, Spanish, Russian, and Arabic. Here's how: Upload your video and use the "Auto subtitles" functionality to generate subtitles. Then, select the translate icon above the subtitle editor and select the foreign language you'd like to translate to. Kapwing will translate your subtitles and automatically update your video.

If you already have an SRT file, you can easily add it to your video in Kapwing. Follow these steps to upload and customize your captions:

1. Upload a video file via a URL link or the files folder.
2. Open the "Subtitles" tab in the left-hand toolbar. Then, select "Upload SRT/VTT" to upload your own captions file.
3. Once your SRT subtitles are uploaded, proofread and customize. When you’re finished editing, click "Export Project" and download your video with embedded subtitles.

Editing subtitles is done through the text transcript on the left-hand side of the screen. Simply click on the transcript to manually edit the subtitle text or adjust its duration. To customize the style, use the right-hand panel to choose a font, size, color, background, animation, and transition.

When you generate subtitles in the Kapwing Studio, they are automatically synced using AI. If you need to fine-tune your subtitle timing or fix alignment issues from an uploaded SRT or VTT file, you can use Kapwing's Sync Subtitles tool. You can manually adjust the timing of each subtitle line by editing the transcript on the left-hand side of the screen. Here, you'll find start and end time columns that allow you to fine-tune the duration of each subtitle for perfect alignment. You can also regenerate your subtitles to perfect the timing.

Kapwing's subtitles workflow ensures videos under 30 seconds generate captions within a few seconds, while short-form videos take 1-2 minutes and longer videos (60 minutes or more) may take a few minutes to process.

Yes, Kapwing's AI Subtitle Generator automatically detects multiple speakers and separates them into individual subtitle sections, allowing you to edit each one separately. You can customize the color, speed, fonts, and other visual elements of each individual speaker.

Yes, in addition to subtitles, Kapwing also supports full closed caption creation. That means you can include non-spoken audio, speaker labels, and other accessibility features — ideal for meeting legal requirements like the European Accessibility Act.

To add subtitles to your files, start by creating a new project in the Kapwing Studio. Click or use drag-and-drop to upload your video or audio file. In the left sidebar, click "Subtitles," then choose

A subtitle is timed on-screen text that represents the dialogue in a video. Subtitles can be written in the same language as the original audio or translated into another language, helping viewers understand speech when they cannot hear or understand the audio.

Subtitles can be added directly to the video or downloaded as a separate SRT or VTT file that compatible platforms and video players display during playback.
