Ever since PPTX became the default presentation file format for PowerPoint 2007 and newer, questions upon PPTX file playback have been flocking into Microsoft’s community. There are quite a lot of questions like: "How can I play my PPTX presentation on the school computer with PowerPoint 2003 installed?" "How can I view PPTX file on my iPad 4?" "How can I share my PPTX slideshow on YouTube?"

Actually, it’s quite simple to solve these PPTX file playback issues. If you want to view PPTX files on your iPad or school computer, just install Microsoft PowerPoint Mobile or upgrade your school computer’s PowerPoint to the latest version. But if you want to upload PPTX to YouTube, you then need to convert PPTX to MP4 or FLV for YouTube. This guide would show you how to convert PPTX to MP4 file so as to let you freely make use of PPTX files for diverse purposes.

Part 1: Convert PPTX to MP4 Free within Microsoft PowerPoint

If you’re familiar with Microsoft PowerPoint, you may know that since MS PowerPoint 2010, Microsoft has added an additional feature – "Create a Video" option. This new feature allows users to export and save PowerPoint to video in either WMV or MP4 format. This means that you could directly open your PPTX file on computer and then make use of this new feature to convert PPTX to MP4, without need to download third-party PPTX to MP4 converter software apps.

The detailed steps on how to export PPTX to MP4 within Windows PowerPoint are listed below:

  1. Open your PPTX file in PowerPoint and then move mouse to and click the "File" menu at the top-left corner.
  2. On the drop-down menu panel, click the "Export" tab and then choose "Create a Video" option.
  3. You will then see a PowerPoint to video converting settings panel, including: 2 drop-down menus and slide duration settings. In the first drop-down menu, select output video resolution (target player to play created video) and size. In the second drop-down menu, select to include or exclude any timings or narrations you prefer. After this, set the time value and then click the "Create a Video" button.
  4. On the popup "Save as" interface, set output video name and determine MP4 as output format from MP4 and WMV. Also, determine a folder to save output MP4 video file.
  5. Click "Save" button. The MS PowerPoint would start to export and convert PPTX to MP4 file immediately.

Part 2: Convert PowerPoint to MP4 with Desktop PPTX to MP4 Converter

Why do we need desktop PPTX to MP4 converter to convert PPTX to MP4 even if we could convert PPTX to MP4 free with MS PowerPoint or free online PPTX to MP4 converter? There are 3 basic reasons for that:

  1. Firstly, quite obvious, no matter you’re using PowerPoint or online free PPTX to MP4 converter, you could only process one PPTX file at a time;
  2. Secondly, both these 2 tools could let you determine the video and audio parameters of output MP4 files, which may result in output MP4 files being not accepted by some media players (we know that a little change of video codec or audio codec might make files not recognized);
  3. Thirdly, the online free PPTX to MP4 converter is not stable. I have tested several online free PPTX to video converters only to get multiple errors on the screen.

Different from these two apps, a desktop PPTX to MP4 converter could not only convert PPTX to MP4, but also enable you to determine the video and audio parameters of output MP4 file according to your target device and player. What’s more, with a desktop PPTX to MP4 converter, you could convert PPTX file to MP4 video in batch.
