To add subtitles in PowerPoint, you need to use one of two distinct methods depending on your goal: live captions for a real-time presentation or closed captions embedded into a video file on a slide. This article covers both approaches, so you can choose the right one for your needs.
How to add subtitles in PowerPoint: the two methods
PowerPoint offers two main ways to add subtitles: live captions during a presentation and closed captions for embedded videos. Live captions transcribe your speech in real time as you present to an audience. Closed captions are text files you attach to a video file that plays inside a slide, so the subtitles appear whenever the video is played. Knowing which method you need is the first step.
How to use live captions during a presentation
Live captions and subtitles require PowerPoint for Microsoft 365 (version 16.0.11601.20178 or higher on Windows 10+, or version 16.22.127.0 or higher on macOS). A reliable internet connection is required, as the feature is cloud-enhanced and powered by Microsoft Speech Services. For best results, a headset microphone connected to the device running PowerPoint is highly recommended.
- Open your presentation and go to the Slide Show ribbon tab.
- Select Subtitle Settings.
- In Subtitle Settings, choose the Spoken Language (the language you will be speaking) and the Subtitle Language (the language to display or translate to).
- To start, begin your slide show. The live captions will appear automatically based on your settings.
If you are wondering how to turn on subtitles during a live presentation, this is the exact process to enable them. The feature will transcribe your speech as you speak.
How to customize the look of live captions
You can adjust the position of live captions (e.g., top, bottom, overlaid, or docked above/below the slide) and other appearance settings like color, size, and font style. To change these, return to the Subtitle Settings menu from the Slide Show tab before or during your presentation. Experiment with contrast and placement to ensure the text is readable without obstructing key slide content.
How to add closed captions to an embedded video
Closed captioning for embedded videos is available in PowerPoint 2016 (Click-to-Run installations only), PowerPoint 2019, PowerPoint 2021, PowerPoint 2024, and PowerPoint for Microsoft 365. PowerPoint supports closed caption files in WebVTT (.vtt) format and, beginning with version 2411, also SubRip Text (.srt) format with UTF-8 encoding.
- Select the video on your slide.
- Go to the Playback tab.
- Select Insert Captions, then choose Insert Captions from the dropdown.
- Browse to your .vtt or .srt file and select it.
Alternatively, you can generate captions for embedded videos automatically within PowerPoint. On the Video tab, select Edit Captions, then Generate captions. This creates a caption file from the video’s audio track. If you need to know how to put subtitles on YouTube, that is a separate process done on YouTube’s platform; this method is only for video files inside PowerPoint. If your slides live in Google Slides instead, you can download Google slides with audio to PowerPoint and caption them here.
Editing and syncing your video captions
Captions for embedded videos can be reviewed and edited within the Captions pane. To open it, select the video, go to the Video tab, and choose Edit Captions. Here you can review each caption line, edit the text, and adjust the timing to match the spoken audio precisely. If you need to know how to embed subtitles into video permanently in vlc, that is a different tool, PowerPoint does not burn captions into the video file itself, but rather attaches them as a separate file that plays when the video is shown in the presentation.
Tips for readable and accessible subtitles
Whether using live captions or closed captions, follow these best practices to ensure your subtitles are effective for all viewers. Choose a clear, sans-serif font like Arial or Calibri. Ensure high color contrast between the text and its background, for example, white text on a dark background or black text on a light background. Position subtitles where they will not block important visuals, typically at the bottom of the slide or video area. Keep the text on screen long enough to be read comfortably, and avoid overcrowding the screen with too many words at once. Live captions and subtitles improve accessibility for audiences who are deaf or hard of hearing, or who are more familiar with another language.
