Working with Multimedia Data

In this section, the following options are discussed:

  • Creating multimedia quotations
  • Creating multimedia quotations while listening to the audio file or viewing the video file
  • Display of multimedia quotations
  • Coding multimedia quotations
  • Activating and playing multimedia quotations
  • Adjusting the size of multimedia quotations
  • Renaming a multimedia quotation
  • Capturing video snapshots as image documents for further analysis

Creating Multimedia Quotations

You can also immediately code multimedia files. However, as especially video files contain so much more information as compared to text, it is often easier to first go through and segment the audio or video file, i.e. creating quotations before coding.

To create an audio or video quotation, move your mouse pointer on top of the audio waveform and mark a section by clicking on the left mouse button where you want it to start. Then drag the cursor to the end position. The times of the end and start positions are shown, as well as the total length of the segment.

As soon as you let go of the mouse, a quotation is created, and you see the blue quotation boundary in the margin area

Creating Multimedia Quotations while Listening / Watching

You can also create an audio or video quotation while listening to or viewing a document. For this, you can use the buttons Mark Quotation Start and Create Quotation buttons in the toolbar above the timeline; or the short-cut keys (see below).
Continue with listening or watching, and setting quotations.

Using Short

To mark the start position: use (<) or (,)

To create a quotation: use (>) or (.)

Which short-cut key to use depends on your keyboard. Use those keys where you do not have to use Shift.

Play the video. If you find something interesting you want to mark as a quotation, click on the (,) or the (<) key. This sets the start position.

To set the end position and create a quotation, click on the (.) or (>) key.

  • A new quotation will be listed in the Quotation Manager, the Project Explorer or Quotation Browser. The quotation ID consists of the number of the document plus a consecutive count in chronological order by time when a quotation was created in the document. The quotation ID 15:5 for examples means that this is a quotation in document 15, and it was the 5th quotation that was created in the document.

  • After the ID you see the quotation reference, which is the start position of the audio or video quotation. The name field is empty. You can for instance add a short title for each multimedia quotation, see below.

  • Depending on the media type, the quotation icon changes.

Audio and video quotations can be easily recognized by their special icon.

Coding Multimedia Quotations

Coding multimedia quotations is not different from coding text or image documents:

Right-click the quotation and select Apply Codes. For further information see: Coding Data.

Activating and Playing Multimedia Quotations

In the Margin Area

To play the quotation, double-click on the quotation bar, or hoover over the audio waveform with the mouse and click on the play icon.

You can move the play-head to any position within an audio or video file by scrolling.

From other Places

  • When you double-click on a multimedia quotation in the Project Explorer, the Quotations Browser or the Quotation Manager, the multimedia document opens at the position where the quotation starts. Click on the space bar to play it.
  • You can preview a multimedia quotation in the preview area of the Quotation Manager or the Quotation Reader.
  • You can preview a multimedia quotation in a network.
  • You can preview a multimedia quotation if it is part of a hyperlink. See Working with Hyperlinks.

Adjusting the Size of Multimedia Quotations

To adjust or change the length of the quotation, drag the start or end position to the desired position.

Renaming a Multimedia Quotation

If you add names to multimedia quotation, they can serve as titles. Short summaries can be added to the quotation comment. This allows you to create a meaningful text output for audio and video segments.

Select a multimedia quotation and add a name in the inspector.
Use the comment area to add further information, e.g. describe the segment and offer a first interpretation

Capturing Snapshots of Video Frames as Image Documents

If you want to analyze particular frames of your video in more detail, you can capture a snapshot.

Move the play head to the desired position in the video.

Click on the camera icon in the toolbar.
The snapshot is automatically added as a new image document to your project. See Creating Quotations im Images for further information on how to work with image files.
