  3. Select High.

Just an experiment, play any song on loud speaker and record in High, Mid and Low voice quality. Now, playback the recorded sound to notice the difference.

After recording, open the file with audio editing software like Audacity to make any necessary changes. One of the main edits will include noise reduction. Now, export the sound in format like mp3, etc. Use this exported audio in your video maker.

The above video will explain you the concept. Rest is practise. Now, get ready for better quality screencast.

One more tip, before making screencast longer than 30 seconds, first create a word document and write whatever you have to speak. Then use a parallel screen or printout this will make video shorter.
