   and convert it to MP4

   Alternatively, you can use a software suite such as Camtasia to achieve a similar result.

   Finally, you can use any meeting software, as long as you have a recording of good quality and your final file is in the MP4 format. Here are some links to instructions on recording a meeting on common platforms:

Audio/Video File Requirements

• All files must be in MP4 Format
• Duration: A maximum of 5 minutes for multimedia presentations; A maximum of 10 minutes for oral presentations
• Format: MP4
• Dimensions: Minimum height 480 pixels
• File size: Maximum 100 MB
• Aspect Ratio: 16:9 (widescreen format)

Tips for recording

1. Check that your final video and audio plays directly in common web browsers like Chrome/Chromium, Firefox, etc. by dragging the video file onto a browser window. You may need to re-encode the video file with different parameters if there is no audio or video portion played on the web browser.
2. Use as quiet an area as possible.
3. Avoid areas that have echo:
1. Rooms should be fairly small;
2. Sound dampening with carpeting, curtains, furniture.
4. Hardline internet connections are highly recommended, but if unavailable, a strong Wi-Fi connection should do the job.
5. A good headset with a microphone set close to your mouth BUT away from direct line of mouth to reduce “pops”. Try to avoid using default, built-in microphones on your computer, if possible.
6. Do a test recording of a couple of minutes and review the sound and picture quality, in the MP4 format, and check the bit rate before recording your entire presentation. Make adjustments as needed.
