You can change the size of a video in PowerPoint by compressing the media directly within PowerPoint or by resizing the video frame on the slide.
Here's a breakdown of how to do both:
Compressing the Video (Reducing File Size)
This method reduces the overall file size of the video, which can be helpful for sharing and presentation performance.
-
Open the Presentation: Open the PowerPoint presentation containing the video you want to resize.
-
Access Info Tab: Go to the "File" tab in the PowerPoint ribbon and select "Info."
-
Compress Media: In the "Media Size and Performance" section, click on "Compress Media." You might see options like "Compress Media".
-
Choose Compression Quality: Select the desired compression quality:
- Full HD (1080p): Good for large screens but may result in a larger file size.
- HD (720p): A good balance between quality and file size.
- Standard (480p): Suitable for online sharing and smaller screens.
- Low Quality (240p): For the smallest file size, but the video quality will be significantly reduced.
PowerPoint will then compress the video based on your selection. Note that compression permanently alters the video within your presentation file.
Resizing the Video Frame (Changing Display Size)
This method changes the size of the video as it appears on the slide without altering the underlying video file.
-
Select the Video: Click on the video in your slide to select it. You should see sizing handles (small circles or squares) appear around the video.
-
Resize: Click and drag one of the sizing handles to resize the video frame:
- Corner Handles: Dragging a corner handle resizes the video proportionally, maintaining its aspect ratio. This is generally the best way to resize to avoid distortion.
- Side Handles: Dragging a side handle only resizes the width or height, which can distort the video. Avoid doing this unless you intentionally want a distorted effect.
-
Reposition (Optional): Click and drag the video to reposition it on the slide.
Important Considerations:
- Aspect Ratio: Be mindful of the video's aspect ratio when resizing. Distorting the aspect ratio can make the video look stretched or squashed.
- Video Quality: Enlarging the video frame significantly beyond its original size can result in a blurry or pixelated appearance.
- File Size vs. Display Size: Compressing the media reduces the file size of the video embedded in the presentation. Resizing the video frame only changes the display size on the slide; it does not affect the underlying video file size.
- Original Video: Compressing a video within PowerPoint permanently alters the video file embedded within the PowerPoint file. Make sure you have a backup copy of the original video if you want to revert to the uncompressed version.
