Add Single-Language Subtitles
When you’re in a noisy place like the subway—or in a quiet public space like a library—it can be hard to hear a video clearly, and sometimes you can’t play audio out loud at all. In moments like these, subtitles aren’t just a “nice-to-have”—they’re essential for making content readable and easy to understand.
In this tutorial, you’ll learn how to:
Create an Add Subtitles project in Add Subtitle
Add single-language subtitles
Adjust subtitle styles
Creating subtitles in Add Subtitle is simple: prepare a local video file or a video link, upload it to the cloud, and you’ll get subtitles quickly—then preview and edit everything right in the editor. You can also access the workflow anytime via AddSubtitle.ai.
Create a Project
Go to the Projects page and click Add Subtitles.
Click Upload to select a local video (or drag and drop your video into the upload area), or click YouTube Link and paste the video URL.
Click Select Language, set the video’s original language (and translation target language if needed), then click Submit to start uploading.
Add Single-Language Subtitles
After the upload finishes, you’ll be taken to the editor automatically. Here you can preview the video and configure subtitle settings.
In the Subtitles panel, click the subtitle settings at the top of the panel and choose how subtitles display:
Source: show subtitles in the original language
Translation: show subtitles in the translated language
Bilingual: show both original and translated subtitles
Off: turn subtitles off
Adjust Subtitle Styles
Once the upload completes and you’re in the editor, you can preview and edit subtitle text.
Click Style on the left, choose a subtitle preset, or click the pencil (Edit) icon in the top-right of a style card to customize the style settings.
When you’re done, click Export in the top-right corner, choose a resolution and format, and export your video.
