Any help would be greatly appreciated.
Do you have any recommendations on how to fix this?
Alternatively, are you aware of any third party toll that can scan and reduce the media in PowerPoints?
I’m trying to find a way to compress videos in PowerPoint. We have hundreds of PowerPoints we’ve designed over the years, some of them hundreds of slides long, many containing 1 or 2 gigabytes of video. The PowerPoint’s embedded video is taking up the majority of our file server space, in these PowerPoints. We need the videos embedded, although the quality should be reduced. Linking the media is not an option. The time it would take to manually export, compress each video, then embed again could take us many days or weeks. PowerPoint should already have this feature built in as described.Compress your media files does not work.
Compress your media files - Microsoft Support
When we attempt to compress video at any resolution, no videos can be compressed.
When attempting to compress, we get these notices:
“Unsupported”.
“These media files could not be compressed”
I thought the PowerPoint file format, video format or resolution may have been unsupported, so I exported and viewed the video properties. The videos are already in a standard format:
MP4 video at Full HD 1080p.
PowerPoint file version is already modern, (.pptx)

If your files are on a shared area, copy a few over to local storage and try again.
If the codec in use is unable to work on UNC paths it’s going to fail.
The media files may also already be optimized, it wont run again if they are.

The PowerPoints are copied onto my local computer’s storage, (no cloud sync).
There are no problems playing back the videos. I can tell the videos are not compressed because when I export a video and view the properties, it shows it’s 1,920 x 1,080 pixels (or 1080p) The options in PowerPoint for compression are 1080p, 720p, 480p. This means that a 1080p video has room for compression, so compression should be supported.
The link shows PowerPoint supports the following video compressions for PowerPoint embedded videos. After research, trail & error, this is why I’m stuck.
Full HD (1080p)
HD (720p)
Standard (480p)

I think you have some concepts confused here.
Video IS already compressed. You can’t compress the videos any further. To get smaller file sizes, you have to change either codec (compression method), bitrate (rate of data flow), or dimensions. The encoding parameters determine the final size in bytes.
I’d be surprised if any compressor software would work with embedded video. You’ll need standalone files unless there is a product out there to specifically work with embedded video and change the parameters.
You may have to write a script to export video, then another to compress and save with different parameters (for example, downsample 1080p to 720p), and finally to re-import the new video. Lots of products can compress video- Adobe Media Encoder and Apple Compressor are purpose-built for video output, plus free stuff like VLC and DaVinci Resolve can handle it.

Sorry to say, although I think I didn’t explain properly. I am not looking to change to bitrate, I’m simply looking to compress the video from 1080p “which is 1920x1080” to 480p “which is 640×480”. Can you help me understand how are the videos already compressed?
According to step 3 of the Microsoft article, Compress your media files - Microsoft Support , the discussed procedure can compress the size of embedded videos:
Step 3. To specify the quality of the video, which in turn, determines the size of the video, select one of the following:
Full HD (1080p) Save space while maintaining overall audio and video quality.
HD (720p) Quality will be comparable to media which is streamed over the Internet.
Standard (480p) Use when space is limited, such as when you are sending presentations via e-mail.
That said, when I manually export a video from the PowerPoint, save it to my computer, then check it’s properties, the properties is reporting 1080p as such:
Frame width 1920
Frame height 1080
Note: We know that 1080p “is 1920x1080”. So why isn’t compression working?
Spiceworks asking if this was resolved. Unfortunately no. Per the supplied Microsoft link I still don’t know why PowerPoint is reporting “Unsupported”, when attempting to compress: Full HD (1080p) INTO → Standard (480p)
