PowerPoint Slideshow Recording: How to Re-Record Single Slide

You recorded a slideshow in PowerPoint, but one slide has a mistake in the narration, a timing error, or a missing animation. Rerecording the entire presentation from scratch wastes time. PowerPoint lets you rerecord a single slide without affecting the audio and timing on the other slides.

The Record Slide Show feature captures your voice, pointer movements, and slide timings as a single continuous video per slide. When you rerecord one slide, the old recording for that slide is replaced. The rest of the presentation stays unchanged.

This article explains the exact steps to rerecord one slide in PowerPoint for Microsoft 365 and PowerPoint 2021. It also covers what happens to existing narration and how to avoid common errors.

Why Rerecording a Single Slide Works Differently From Rerecording the Entire Show

When you record a slideshow, PowerPoint stores each slide’s narration and timing as a separate media object inside the slide. The Record Slide Show tool does not create a single video file of the whole presentation. Instead, it keeps per-slide audio clips and timing data in the slide’s transition settings.

This design allows you to replace the recording on one slide without touching the others. The Clear command on the Record Slide Show menu lets you choose between clearing the current slide or all slides. After clearing, the Record from Current Slide command starts a fresh capture for that slide only.

One important detail: the new recording will overwrite any existing narration and timings on that slide. It will not merge or layer audio. If you want to keep the original audio and add a voiceover later, you must insert an audio file manually instead of using the recording tool.

Steps to Rerecord a Single Slide in PowerPoint

These steps work in PowerPoint for Microsoft 365, PowerPoint 2021, and PowerPoint 2019. The Ribbon interface is the same across these versions.

1. Open the presentation and select the target slide
   In Normal view, click the slide you want to rerecord in the thumbnail pane on the left. The slide appears in the main editing area.
2. Open the Record Slide Show menu
   Go to the Slide Show tab on the Ribbon. Click the small arrow below the Record Slide Show button to expand the dropdown menu. Do not click the main button directly because that starts recording immediately.
3. Clear the existing recording on the current slide
   In the dropdown menu, select Clear. Then choose Clear Recording on Current Slide. This removes the narration and timing for that slide only. The slide number remains unchanged and the other slides keep their recordings.
4. Start the new recording from the current slide
   Click the Record Slide Show button again to expand the dropdown. Select Record from Current Slide. PowerPoint switches to full-screen slideshow mode with the recording toolbar at the top left corner.
5. Record the narration and pointer actions
   Speak into your microphone. Use the on-screen pen, highlighter, or laser pointer if needed. The recording toolbar shows elapsed time for this slide. Pause by clicking the pause icon. Resume by clicking the microphone icon.
6. Stop recording and save
   Press the Escape key on your keyboard or click the End Show button on the recording toolbar. PowerPoint returns to Normal view. The new recording is saved automatically. You do not need to save the presentation file separately at this point, but it is good practice to press Ctrl+S after finishing.

If You Want to Rerecord Multiple Non-Consecutive Slides

Repeat the process for each slide individually. Clear the recording on each slide before recording it again. Attempting to record over a slide that still has a recording will not work the first time because PowerPoint will play the old recording instead of starting a fresh capture. Clearing is mandatory.

Common Problems When Rerecording a Single Slide

PowerPoint Does Not Let Me Select Record from Current Slide

This happens when the slide has never been recorded before. The Record from Current Slide option is available only after a recording exists on that slide. If the slide is blank of narration, use the Record from Beginning option instead and advance to the target slide manually during the recording. Alternatively, record the entire show once, then clear and rerecord the specific slide.

The New Recording Does Not Replace the Old One

If you skip the Clear step, PowerPoint may play the old recording on top of your new narration. In some versions, the old and new audio play simultaneously. Always run Clear Recording on Current Slide before recording again. If audio still overlaps, close the presentation without saving, reopen it, and repeat the clear-and-record sequence carefully.

Timing on Other Slides Changed After Rerecording One Slide

This occurs when you have Use Timings enabled in Set Up Slide Show and the new recording has a different duration. Other slides keep their original timings. The overall presentation length changes only by the difference in duration of the rerecorded slide. To keep the total time predictable, match your new narration length to the original recording. You can check the original duration in the Recording toolbar before clearing.

Microphone Not Detected During Recording

PowerPoint uses the default input device set in Windows. Open Windows Settings > System > Sound > Input and confirm your microphone is selected and working. In PowerPoint, the recording toolbar shows a microphone icon with a red dot when audio is being captured. If the icon is gray, click it and select a different device from the dropdown.

Recording a Single Slide: Slide Show Recording vs Screen Recording

Item	Slide Show Recording	Screen Recording
Purpose	Captures narration, timings, and pointer actions per slide	Captures any on-screen activity as a video clip
Output location	Embedded in each slide as narration and timing data	Inserted as a video object on the selected slide
Replace single slide	Clear and rerecord the slide directly	Delete the video object and insert a new recording
Timing control	Advance slides automatically based on recorded timing	No automatic slide advance; user controls playback

Use Slide Show Recording when you need self-running presentations with automatic slide transitions and voice narration. Use Screen Recording when you want to capture a demo or tutorial as a standalone video that stays on one slide.

Conclusion

You can rerecord a single slide in PowerPoint by clearing the existing narration with Clear Recording on Current Slide and then starting a new recording with Record from Current Slide. This method keeps the rest of the presentation intact and avoids rerecording the entire show. Always verify that the microphone is working before you start. For presentations that require consistent timing across slides, match the new narration length to the original recording. After rerecording, preview the slide in Slideshow view to confirm the audio and pointer actions play correctly.
