How to made a screencast?

3. Preparing before the record

Preparing to record can be long and complicated process, but you will gain confidence while you are recording.

Begin with clarifying the audience and objectives of the record.
Create a storyboard of your video to sketch your video. You should see where and how the content elements and other effects will go.
Check out the basic terminology and concepts of screen capture. A bit of understanding about video sizes, video file formats, screencasting will make you feel more prepared and confident.
Very importantly, you should think about the file size of your screencast. If the video is too long, your audience may lose interest. It is recommended that you keep the length of your video to no more than 6 minutes.
Choose the program you want to record screencasting.
Arrange your desktop computer to clear unwanted icons, programs, bookmarks, etc.
Find and arrange the necessary files for the recording: graphics, videos, texts, etc.
Create a folder for each of your video projects. In that folder, put all of your recordings, project files, produced videos, and media files.

Recording could be done by recording your own voice to the screencasting process or by any voice recording application. You can choose between a live, real voice with possible pronunciation mistakes or a properly spoken text of the program, which, however, will be more difficult to reconcile with the on-screen events.
