You can record an audio clip using your mobile phone itself, using any audio recording app, such as ‘[https://play.google.com/store/apps/details?id=com.sonymobile.androidapp.audiorecorder Audio Recorder]’. You can copy the audio file from your phone to your computer for editing and re-mixing to create OER. While recording, make sure that no copyright music or sound is playing in the background. We have recorded a short interview with a teacher on why Digital Storytelling is important, using a mobile phone. We  have copied this audio clip to our computer, by connecting the mobile phone to the computer with a data cable and renamed the file as ‘Interview - why Digital Storytelling.’

We saw earlier that audio clip can be cut and pasted like text documents.  A similar moving and combining is possible for video clips also.  You can do this in Open Shot video editor application, by cutting and using drag and drop options of the video file. You can also delete a part of the clip also using delete key from the keyboard (or right click and remove clip) and remove any part of the video clip you do not want. You can move a part of a clip from one place to another (for instance if you want to re-order responses in an interview).

To demonstrate this we have edited a video where two teachers (one male and second female) are speaking about their work in integrating technology in their subject teaching. (Author of video - IT for Change).  We have used this option to move the interview of the male teacher after the interview of the female teacher.  Watch the two videos below.

Often you want to add images or text to a video.  These can be inserted as slides.  By inserting the slides at different times in the track, we can add images or text to a video.  To demonstrate this, we have worked with our video of teachers and introduced a  title slide introducing each teacher before they begin speaking.  You can add slides as required to introduce your own narrative in your video to practice.
