Hi Mu,
Good day. Thank you for posting your question in the Microsoft Q&A Forum.
To better understand your request and assist you accurately, could you please clarify what you would like to do with your MP4 file?
Do you want to:
- Remove only the audio and keep the video?
- Remove the video and keep only the audio?
- Remove both the audio and video from the MP4 file?
Please note that if both the audio and video are removed from an MP4 file, the file may no longer contain any playable media content.
- Also, could you please confirm whether you are using PowerPoint for the web or the PowerPoint desktop application?
Please feel free to share the information in the comment below. Once I have it, I’ll be better positioned to guide you through the next steps.
Thank you again for your patience and cooperation.
I’m looking forward to your reply.
