Automatic coding in audio and video sources

---

If you have added custom fields (columns) in your audio or video transcripts, you can use them to quickly code an audio/video source.

For example, if you added the custom field Speaker, NVivo can create a node for each speaker and code the content at that node—this way you can gather everything said by a specific person.

Understand automatic coding in audio and video sources

NVivo provides ways for you to auto code your audio and video sources. You can auto code based on:

• Custom transcript fields  If you have added custom fields (columns) in your audio or video transcripts you can use them to auto code the transcript.  For example, if you added the custom field Speaker, NVivo can create a node for each speaker and code the content at that node—this way you can gather everything said by a specific person.

• Existing coding patterns  If you have NVivo 10 for Windows Service Pack 4 (or later), you can also code the text in the content column using existing coding patterns.

For example, if you have already coded some sources to the nodes Water quality and Habitat, then you can automatically code additional content containing similarly worded text passages to the nodes Water quality and Habitat.

Auto code a transcript using custom fields

To auto code a transcript using custom fields

1. In List View, select the audio or video source you want to auto code.

NOTE When auto coding multiple sources, you can only select the same source type—all audio or all video sources.

2. On the Analyze tab, in the Coding group, click Auto Code.

The Auto Code Wizard opens. Follow the steps on the Wizard.

 

Wizard step	What to do
Step 1	Click Auto code using source structure or style.
Step 2	From the Available Transcript Fields list, select the custom fields you want to use for coding. Click the right arrow button >> to add the custom field to the Selected Transcript Fields list. Click the right arrow button >> to add the styles to the Selected paragraph styles list. NOTE A node is created for each unique text string in the custom field and the text in the Content field is coded at the node. The order of the custom fields in the list determines how they are nested in the node hierarchy—the first custom field is the parent of the second and so on.
Step 3	Select where you want to store the newly created nodes. Choose: Existing Node to store the created nodes under an existing parent node—click Select and choose the parent node. New Node to store the created nodes under a new parent node—in the Name field enter a name for the new parent node. Click Select to choose a different location for the new parent node. Existing Folder to store the created nodes in an existing folder—click Select and choose the existing folder. New Folder to store the created nodes in a new folder—in the Name field, enter a name for the new folder. Click Select to choose a different location for the new folder. (Optional) Select the Aggregate coding from child nodes check box, if you want the content coded at child nodes to be shown in the parent node.

Auto code transcripts based on existing coding patterns

You can also use pattern-based auto coding in conjunction with the other coding techniques. For example, you gather multiple interview responses into a node for each question.  Then, you could use pattern-based coding to 'code on' from a question node.
