1. Prepare your PowerPoint presentation that you want to upload. Ensure it is fully edited and at the quality level you want published, then click File.
2. Go to Export > Create a Video. Set the video quality to Full HD (1080p) using the quality dropdown, adjust the seconds-per-slide duration to your preferred timing, then click Create Video.
3. In the export panel, If your slides include recorded narration or timings, select Use Recorded Timings and Narrations.
4. Choose a save location, and confirm the file format is set to MPEG-4 Video (.mp4). Click Save and wait for PowerPoint to export the file - this can take several minutes for long presentations.
5. Go to studio.youtube.com and click the Create icon at the top right, then select Upload videos.
6. Upload the exported MP4. Add a title that matches your presentation topic, a description, and relevant tags while the file processes.
7. Under Audience, select No, it's not made for kids, if the content is business-facing.
8. Set visibility to Public, Unlisted, or Private depending on your distribution plan. Click Publish (or Schedule if setting a future date) to complete the upload.
