Small file sizes are ideal as they don't hog server resources or frustrate dial-up users. Posting audio and video information online is convenient, but you must also consider the variety of platforms, media players, settings, and connection types that your audience will have. For audio only, MP3 files are small and fairly universal. Video files are not yet as standardized, but MPEGs are generally playable on most machines. If posting video online, try to keep it to a reasonable length (10 minutes or less).
Save video files as an MPEG4. Save audio files as an MP3. Upload the file to the course content. Create a link to the file that can either be played online in the browser or saved as a file on the users local machine, so they can listen to it later, offline.
Upload the file to YouTube.com. You must first have an account, and all content on YouTube becomes publicly available. If restricted access is a concern, give the video an obscure title so it can't be easily located with a search. Then, manually provide the URL link to the intended audience.

- Use a USB microphone
- Have the microphone between 6” - 2' away from the audio source (e.g., your voice)
- Do all recording from the same distance and position to maintain a consistent sound profile
- Read from a script
- Export as MP3 file types (32 kbps for voice-only narration; 192 kbps for music or more complex audio recordings)
- Record short segments
- Make sure the sound waves are large enough to indicate a good moderate volume level without extending past the top and bottom of the track container. See the image below for an example of good volume levels in a recording:
- Set a screen resolution no larger than 600 x 800 for web distribution
- Relatively short videos and audio files that introduce, explain, etc.
- Recorded lectures (audio, mostly)
- Media that fills a need
- Video clips in multiple formats
- Linked media files (suitable for right-click)
- Media also available via CD
