PowerPoint 2013 accepts more video file formats than previous versions, and can do a lot
more with videos, including trimming of video clips. However, it also embeds
all inserted video clips by default -- and this can result in huge presentations that contain huge video files! This ultimately occupies oodles of
disk space and may also make PowerPoint work a wee bit slower. To tackle this problem, you can explore the media compression abilities built right
inside PowerPoint 2013 -- you no longer need any third-party media compression tool since PowerPoint's native Media Compression
options make this task very easy indeed.
Note: Although the techniques explained in this tutorial pertain to video compression, they work for audio files too.
Follow these steps to learn more about video compression options:
- Open a presentation where you have already inserted a video clip that
you want to compress. Optionally, save your presentation as a new file if you also want to have an original, uncompressed version of the presentation.
- Now, access the File menu, and choose the Info option, as shown in Figure 1. Thereafter, click
the Compress Media button, highlighted in red within Figure 1.

Tip: Do not see any
Compress Media button? This option shows up only if you have video or audio clips inserted
within PowerPoint. There are exceptions too -- you will not see the
Compress Media button if you used an
online video. Also, if you choose to link a video clip rather than
embedding it, this button will be visible, but grayed out. To learn how to link a video rather than embed it within a presentation, look at
step 3 in our
Insert Video (Movie) Clips in PowerPoint
2013 tutorial.
- This brings up the Compress Media drop-down menu, as shown in Figure 2.

The top three options within the Compress Media drop-down menu are explained below:
- Presentation Quality: Helps save space and also at the same time maintains the overall audio and video quality.
- Internet Quality: Video quality post compression is comparable to video typically streamed over the internet.
- Low Quality: Produces video of very low quality hence can be used when file size is more important than quality.
Click to choose any one of the compression quality levels.
- This opens the Compress Media window which shows the compression process. Once the compression is done, you can see the disk
space you saved at the bottom of the Compress Media window, as shown in Figure 3.

Click the Close button to get back to Backstage
view.
- Preview your video after compression, if you are unhappy with the compression result you can undo the compression. To do so, click the
Compress Media button again, and select the Undo option from the resultant drop-down menu, as shown in
Figure 4.

Note: The Undo compression option will be available only till the presentation is open. As soon as you save and
close the presentation, the compression will be permanently applied to your video clip. Close your presentation only if you are happy with the
compression.
Note: Compression of any type will finalize any
Trim Video
options you chose -- after compression, all parts of the video that were trimmed away will no longer be available. Also, the
Reset options will only reset the appearance of the video.
- Make sure you save your presentation.
