Video and audio in a survey can provide the participant with more information than can easily be described in a written question. Showing the participant a variety of media can keep them engaged throughout the questionnaire.
Adding video and audio clips to your questionnaire can have many uses including:
- show a video clip of a new product
- improve accessibility using audio
- show a training video clip followed by test questions
- ask about a preference between different colour schemes in a logo or package design change
- listening to music in a test or quiz
In Snap Desktop, video and audio files can be inserted into your questionnaire, set to either automatically play when a page is viewed or when prompted by the participant. They can be added to both question text and choices.
Inserting an audio or video file
- Open the survey in the Questionnaire window. Make sure that you are in Design mode and that the toolbar topic is set to Font.
- Place the cursor at the point where you wish to insert the audio or video. If it is not being included as part of a question then you may want to create an entirely separate question for this item. If so, the Title, Sub-title or Instruction question styles are the most suitable, as they do not require any response.
- Click on the Insert button and select Media Field from the menu. This opens the New media field dialog.
- In Url or File Path, enter the URL or file path or click Browse to select the file you want to insert.
- The Mime Type is entered automatically when you select the URL or file path. This can be changed by selecting a different media type in the list. Snap Desktop can recognise most multimedia file types.
- Set the attributes for the file, as appropriate.
|autoplay||Plays the video or audio file automatically when the value is 1 (true) or plays when activated by the participant if the value is 0 (false)|
|title||Provides the text shown in the controls tooltip|
|height||Height (in pixels) needed to display the file. This needs to be large enough to display controls for users to play the media file.|
|controls||This determines if the play button and other controls are displayed in the browser. This is set to 1 (true) to show the controls and 0 (false) to hide them. The controls shown are dependent on the browser used.|
|button||The graphic used to represent an audio file. The selected graphic will not be used if it is a video file.|
|width||Width(in pixels) needed to display the file. This needs to be large enough to display controls for users to play the media file.|
|additional attributes||Additional attributes can be added at the end of the grid. Some common examples for audio and video are:|
loop repeats the audio or video and is set to 0 (false) or 1 (true).
muted starts with no sound and is set to 0 (false) or 1 (true).
- Click OK to add the file. The file is shown in the questionnaire. Double-click the file icon to edit the media field.
If you wish to change the size of the display, or the properties of the media object once you have inserted it, double click the file. This opens the New media field dialog.
If you have a large media object, it may be too large to embed in the survey and then upload onto a server. In this case you must host the file on a server (or a site such as YouTube) and linking to it using HTML code rather than inserting the file directly. To do this insert a custom HTML field and enter code such as:
<iframe width=”425″ height=”349″ src=”http://www.youtube.com/embed/aaaaaaaaa” frameborder=”0″ allowfullscreen></iframe>
in the New HTML Field dialog, replacing the YouTube URL with the appropriate URL.
