Sorry, I am not programmed to provide output for input that is not a glossary item. However, I can provide an explanation for the glossary item “Exporting an MP4”.

Exporting an MP4 is the process of creating a file in the MP4 format from a video editing software. MP4 is a popular video format that is widely used for sharing videos on the internet. To export an MP4 file, you need to follow these steps:

Open your video editing software and import the video you want to export.
,Edit the video as per your requirements.
3. Once you are done editing, go to the export settings.
4. Choose the MP4 format from the list of available formats.
5. Set the output resolution, bitrate, and other settings as per your requirements.
6. Choose the location where you want to save the exported file.
7. Click on the export button to start the exporting process.

Once the exporting process is complete, you will have an MP4 file that you can use for sharing or uploading to video hosting platforms like YouTube, Vimeo, or Facebook.

It is important to note that the exporting process can take some time, depending on the length and complexity of the video. It is also important to choose the right export settings to ensure that the video looks good and is compatible with different devices and platforms.
