Summary

Exporting a deck as an MP4 turns a presentation that needs a presenter into one that plays itself — for people who missed the meeting, for a stand at an event, or for anyone in a different time zone. This article covers recording narration and timings, choosing a resolution, running the export, dealing with a file too large to email, and producing an animated GIF when you need a short silent loop instead.

Before You Start

• Microsoft PowerPoint, desktop version. Create a Video is not available in PowerPoint for the web.
• A microphone if you want narration. A built-in laptop microphone works; a headset sounds noticeably better.
• Free disk space of roughly 100 MB per minute of finished video at 1080p, plus room for PowerPoint's temporary files during the export.
• No admin rights required.

Instructions

1. Record Narration and Slide Timings First

Skip this step if you want a silent video on a fixed timer. Do it if you want the video to sound like you presenting.

1. Open the presentation and click the Slide Show tab.
2. Click Record in the Record group, then choose From Beginning. In PowerPoint 2019 and some 2021 builds the button reads Record Slide Show, with the same two options under its dropdown arrow.
3. The recording studio opens full screen: your current slide fills the middle, the next slide sits to the right, and a red circular Record button sits at the top left.
4. Check the microphone and camera icons at the bottom right. Click the microphone icon to pick a specific input device. Turn the camera off unless you want your face in the corner of every slide.
5. Click Record. A 3 - 2 - 1 countdown runs, then recording starts and a timer begins counting under the slide.
6. Speak your commentary and click the arrow at the right edge, or press the Space bar, to move to the next slide. PowerPoint stores the audio and the elapsed time separately for each slide.
7. Use the pen, highlighter, and laser pointer icons along the bottom to mark up a slide while you talk. Those marks are captured in the recording.
8. Click Stop, then Esc or the X at the top right to leave the studio.

Verification: Back in Normal view, a small speaker icon appears in the bottom-right corner of every slide you narrated, and the timing in seconds appears under each thumbnail when you switch to View > Slide Sorter. No icon means no audio was captured on that slide.

To redo a slide, select it, click Record > From Current Slide, and record again — the new take replaces the old one. To wipe everything and start over, click the Record dropdown arrow and choose Clear > Clear Timings on All Slides or Clear Narrations on All Slides.

Tip: For timings without audio, use Slide Show > Rehearse Timings instead. You click through the deck at presentation pace and PowerPoint saves how long you spent on each slide.

2. Open the Create a Video Screen

Every video setting lives on one screen.

1. Click File in the top-left corner of the PowerPoint window. The backstage view opens.
2. Click Export in the left-hand list.
3. Click Create a Video in the Export column.
4. The right-hand pane fills with two dropdowns stacked above a Seconds spent on each slide box and a Create Video button.

3. Choose a Resolution

The first dropdown sets the picture size. Each option names its pixel dimensions and its file size trade-off.

The video is rendered at the aspect ratio of your slides, so a 4:3 deck exports with black bars down the sides on a widescreen player. Fix that before exporting rather than after — see How to Change Slide Size in PowerPoint.

• Ultra HD (4K) — 3840 x 2160. For a large screen, a video wall, or footage that will be re-edited later. Produces by far the largest file and the longest export.
• Full HD (1080p) — 1920 x 1080. The right default for almost everything: Stream, SharePoint, Teams, YouTube, and anyone watching on a laptop or monitor.
• HD (720p) — 1280 x 720. Roughly half the file size of 1080p with text still comfortably readable. Choose this when the file has to fit an attachment limit.
• Standard (480p) — 852 x 480. Smallest file. Fine for a phone-screen preview, too soft for slides carrying small text or detailed charts.

1. Click the first dropdown, which reads Full HD (1080p) by default.
2. Select the resolution you want. The text below the dropdown updates to describe the choice.

Note: Exporting at 4K does not make blurry images sharp. The output resolution cannot add detail that was not in the pictures on your slides — it only enlarges what is there and inflates the file.

4. Choose Recorded Timings or a Fixed Seconds Per Slide

The second dropdown decides what drives the pace of the video.

If you recorded in step 1:

1. Click the second dropdown and select Use Recorded Timings and Narrations.
2. Each slide holds the screen for exactly as long as you spoke over it, and your audio plays with it.
3. Any slide you did not record falls back to the value in the Seconds spent on each slide box, so leave that box at a sensible number rather than zero.

If you did not record:

1. Click the second dropdown and select Don't Use Recorded Timings and Narrations.
2. Click the Seconds spent on each slide box and type a duration. The default is 05.00. For slides carrying a paragraph of text, 08.00 to 10.00 gives a viewer time to read.
3. Every slide holds for that same duration, and the video is silent.

Note: The seconds-per-slide value includes any transition time on the slide. A 3-second Morph transition on a 5-second slide leaves 2 seconds of static viewing. Raise the number, or shorten the transition on the Transitions tab.

5. Create the Video and Wait for It to Finish

This is the part that takes real time. Start it when you can leave the machine alone.

1. Click Create Video. A Save As dialog opens.
2. Choose a folder and type a filename.
3. Set Save as type to MPEG-4 Video (*.mp4). Choose Windows Media Video (*.wmv) only if you are handing the file to a system that specifically requires it — MP4 plays everywhere, WMV does not.
4. Click Save. The dialog closes and a progress bar appears in the status bar along the bottom of the PowerPoint window, reading Creating video followed by your filename.
5. Leave PowerPoint open. Closing it, or closing the presentation, cancels the export and leaves an unusable file.

Expect roughly one to three minutes of export for every minute of finished video. A 20-slide deck with 10 minutes of narration at 1080p commonly takes 15 to 30 minutes. Embedded video, Morph transitions, and 4K output all push it toward the longer end.

You can keep editing other slides while the export runs, but PowerPoint will feel sluggish and the export will take longer. To stop it, click the X beside the progress bar in the status bar.

Verification: The progress bar disappears and the status bar returns to normal. Open the folder you saved to and play the file. Confirm the audio starts on slide one and the last slide is present — a truncated file means the export was interrupted.

6. Check the File Size and Send It

Video files are large, and email attachment limits are not.

1. Open the folder containing the video in File Explorer.
2. Right-click the file and select Properties to read the size, or switch the folder to Details view to see it in a column.

As a rough guide at 1080p, expect 50 to 150 MB per minute depending on how much motion and imagery the slides carry. Outlook rejects attachments over roughly 25 MB, and encoding adds around 30 percent in transit, so anything above 15 MB is safer sent another way.

When the file is too big to email:

• Send a link instead. Upload the MP4 to OneDrive or a SharePoint document library, then use Share > Copy link and paste the link into your message. The recipient streams it without downloading. Full detail is in How to Send Large Files Without Email Attachments.
• Export again at a lower resolution. Repeating steps 2 to 5 at HD (720p) roughly halves the file with little visible loss on a laptop screen.
• Trim the dead air. Long pauses at the start and end are pure file size. Open the MP4 in a video editor and cut them — How to Edit Videos for Free Using Microsoft Clipchamp covers the free option that ships with Windows.
• Shrink the deck before exporting. Full-resolution photos inflate the video as well as the .pptx. See How to Shrink a Large PowerPoint File.

7. Export a Short Loop as an Animated GIF

For a few slides that need to loop silently — a product teaser in an email, a banner on an intranet page — a GIF beats a video.

1. Click File > Export > Create an Animated GIF.
2. Choose a size from the quality dropdown: Extra Large 1080p, Large 720p, Medium 480p, or Small 240p. GIFs grow fast, so Medium 480p is a sensible starting point.
3. Set Seconds spent on each slide. The default is 01.00.
4. Tick Make Background Transparent if the GIF needs to sit on a coloured page rather than its own white block.
5. Under Make GIF from slides, set the From and To boxes to the slide range you want. Leave this at the full range only if the deck is genuinely short.
6. Click Create GIF, choose a folder and filename, and click Save. A progress bar appears in the status bar as before.

Verification: Double-click the finished .gif file. It opens in Photos and loops continuously. Check the size — a GIF over about 5 MB will load slowly in an email client and many intranet platforms reject it.

Note: GIFs have no sound and only 256 colours. Photographs come out banded and blotchy. Keep GIFs to slides made of text, shapes, and flat colour, and use MP4 for anything with a photograph in it.

Troubleshooting

INFO

PowerPoint renders the whole deck frame by frame during an export, so the application stays busy for the duration and the progress bar is the only signal that anything is happening. A window that looks frozen mid-export is working, not crashed. Give it the full expected time before assuming otherwise.

Symptom / Error	Potential Cause	Solution
Create a Video is missing from File > Export	Using PowerPoint for the web	Video export is desktop-only. Open the file in the PowerPoint desktop app.
The exported video is silent	Timings dropdown set to don't use, or nothing recorded	Set the second dropdown to Use Recorded Timings and Narrations (step 4), and confirm a speaker icon appears on each narrated slide in Normal view.
A slide flashes past before its animation finishes	Slide has no recorded timing	Record that slide again with Record > From Current Slide, or raise the Seconds spent on each slide value (step 4).
The export finished but there is no file	Export cancelled, or the disk filled	Check available space on the save drive, close other applications, and run the export again at a lower resolution.
An online video on a slide is missing from the export	Only embedded media is rendered	Download the clip and insert it with Insert > Video > This Device, then export again.
The file is too large to attach	1080p or 4K output	Export at HD (720p), or share a OneDrive link instead (step 6).
Narration is quiet or picks up room noise	Wrong input device selected	Re-record after clicking the microphone icon in the recording studio and choosing your headset rather than the built-in array (step 1).
