2.9.3 Audio-visual files

You can include the following within your question:

  • flash animations - files ending in .swf.
  • audio - files ending in .mp3.
  • video – MPEG4 (ending in .mp4) or Flash (ending in .flv) video files.

Adding audio-visual files to questions

  1. Within your text highlight a word or words.
  2. Click on the link icon.
  3. Browse to the a/v file on your hard-disk and upload it into your question.
  4. By default the link to the file will be displayed at run-time as well as the audio-video player containing the file. If you change the link to the ‘.’, character at run-time the ‘.’ will not be displayed and you will simply see a clean audiovisual player.

Adding audio-visual transcripts to questions

  1. Place the editor into HTML mode (so that you can see the HTML code).
  2. Insert <h4>TRANSCRIPT_START:512:Name of video</h4> ...arbitrary HTML that is the content of the transcript... <h4>TRANSCRIPT_END</h4>

Once inserted into the question the transcript is included in the question. On display the student just sees a ‘display transcript’ link. Click on it and the transcript appears in situ.

Placing a static image over the video prior to playing

  1. Add the image to the text field in the normal way.
  2. Place the editor into HTML mode (so that you can see the HTML code).
  3. Append the following to the end of the video link ?d=<width>x<height>&subtitles=empty.srt&image=<image filename>
    • <width> and <height> are the size of the video window
    • empty.srt is a placeholder. It need not exist.
    • <image filename> should be the file name of the image that has just been uploaded.

    Example: <p><a href="http://learn3acct.open.ac.uk/draftfile.php/267/user/draft/117435983/NG_02.flv?d=400x300&amp;subtitles=abc.srt&amp;image=daj.png">video</a></p>

  4. Save the question and try it. If all is well the initial image can now be removed.
