Audio and videos
Import your audio or video files and analyze the content in NVivo.
A video or audio file consists of a media file and a transcript:
1Media timeline—you can play, code and annotate the media using the timeline.
2Media—you can resize the display and use the controls to play, pause and rewind
3Transcript—you can import a transcript or play and transcribe the media in NVivo.
You can also have your media automatically transcribed using the integrated transcription service NVivo Transcription.
You can import files with the following formats:
- MPEG-1 Audio Layer 3 format (mp3)
- MPEG-4 audio format (m4a)
- Microsoft Windows Media formats (wma, wav)
- MPEG formats (mpg, mpeg, mpe, mp4)
- Windows Media formats ( avi, wmv)
- QuickTime formats (mov, qt)
- 3G Mobile Phone format (3gp)
- AVCHD High Definition Video formats (mts, m2ts)
NVivo relies on the codecs installed on your computer to decode media files. If the required codec is not installed on your computer, you will not be able to import or play the file, even if it is in a supported format.
You can use Windows Media Player to see a list of components including codecs installed on your computer:
1. Start Windows Media Player (from the Start menu, click All Programs>Windows Media Player).
2. On the Help menu, click About Windows Media Player. If the Help menu is not visible, you may need to show the menu bar.
3. On the About Windows Media Player dialog box, click Technical Support Information.
Your web browser will open a page that includes information about related binary files, codecs, filters, plug-ins and services installed on your computer. You may be able to see that the codec you require is missing or you might give this information to a technical support person to help troubleshoot your problems with importing and playing particular media files.
If you know the name of the codec or its ID (Known as a FourCC identifier for video codecs or a WaveFormat identifier for audio codecs), you can try searching the Internet. You may be able to go to a codec manufacturer's website and download the most recent version of the codec.
CAUTION We recommend you install only codecs from trusted authorized files
Import an audio or video file
- In Navigation View, click the name of the files folder that you want to import the audio or video into.
- On the Import tab, in the Data group, click Files.
- Browse for and select the file you want to import.
- Click the Open button.
- Click OK.

- (Optional) Click the Audio or Video tab to set options for storing the media file—you can embed it in the project or store it outside the project on your computer or a network.
- Click OK.
- If you receive a message indicating that the media file cannot be imported, check that your media is in one of the supported formats.
- If the audio or video contains the responses of a particular case, you may want to code the entire media file at a new case node—click the More button, and then select the Code files at case nodes located under check box.
- The new case nodes are added at the root level of the Nodes folder, unless you click Select and specify an alternative location.
- If you want to classify the new case nodes—click the Select button and choose the classification. All attributes will be set to default values.
- You can import multiple files at the same time.
- If you want to edit audio or video material, you will need to do this before importing it into NVivo. For example, you might want to import only a short segment from a longer video, or hide the identity of participants. Determine what editing software you will use and check the equipment manuals for information about downloading media files from a recorder to your computer.
- Consider where you want to store your media files. If you are going to work with large video or audio files, you may want to store them outside of your project.
- If you want to import transcripts for your audio or video files, ensure that they are correctly formatted. Audio and video transcripts
- If you want to create case nodes for your audio and video files as you import them, your files should be appropriately named.
What can I do in an audio or video file?
When working in an audio or video file you can:
- Create a transcript—you can transcribe the media in NVivo yourself, you can import an existing transcript, or you can have your media file transcribed using the integrated transcription service NVivo Transcription. If you don't need a transcript, you can leave it blank
(and hide it if you want to).
- Play, pause, forward and rewind the media—you can go to an exact location using the timeline
- Code the media directly on the timeline or code the text in the Content column of the transcript
- Annotate the media directly on the timeline or annotate text in the Content column of the transcript.
- Create see also links from the timeline or text in the Content column of the transcript
Can I work with the transcript only?
You can work with a transcript, even if the audio or video is not available.
- You are working in the field and the media is stored on a network drive at the office.
- You are working with a video file containing YouTube content, but are not connected to the Internet.
When you open an existing audio or video file where the content is not available, you are prompted to work without the audio or video. If you choose this option, the file opens and you can work with the transcript.
You can also create an audio or video file without the media content. This is useful in situations where you have a transcript, but do not have the original recording.
Work on the transcript and import media content later
You can create an audio or video file without importing the media file. This is useful if you want to work on the transcript and import the file later on.
In the blank area of List View, right-click to display the shortcut menu and then click New File > New Audio or New Video.
- In Navigation View, click the folder for the new file.
- On the Create tab, in the Files group, click Audio or Video.
- Enter a name for the file.
- (Optional) Enter a description for the file.
- Click OK.
The new audio or video file is opened in edit mode and you can add content to the transcript.
- Open the audio or video file.
- Make sure you are in edit mode.
- On the Edittab, in the Import group, click Media Content.
- Select the file and click Open.
Where are media files stored?
The media content in an imported audio/video file can be embedded in the project or stored outside of the project on your computer or network. Storing media outside of the project is useful when you are dealing with many or very large media files—embedding large files can impact on project performance. If you subsequently move the media file to another location on your computer or network, you will need to re-link it.
The way you work with audio and video (coding, linking and annotating) is the same whether the media file is embedded or stored outside the project.
- Open the file that contains the media file.
- On the Home tab, in the Item group, click Properties.
- Click the Audio or Video tab.
- Under Media, click Not Embedded - file location, then click Browse to specify the location for the stored media file and click OK.
You can store media files outside of your NVivo project, either on your computer or a network location. If you move these files to a new location, you need to 're-link' them in NVivo:
- In List View, select the source that references the media file.
- On the Home tab, in the Item group, click the arrow below Properties, and then click Update Media File Location.
- Locate and select the file in its new location.
- Click Open.
NOTE If you have moved a media file, an error message will prompt you to relink the file.
If you have moved a folder of media files to a new location, you can re-link them as a group:
In List View, select the sources that reference the relocated media files.
On the Home tab, in the Item group, click the arrow below Properties, and then click Update Media File Location.
Locate and select the new folder that contains the media files.
NOTE A message is displayed listing any media files that cannot be found in the selected folder.
If your media files are stored outside the NVivo project (on a CD or network location) there may be times when you do not have the CD or are disconnected from the network.
You can still work with audio/video transcripts, even if the media is not available.
- Open the audio or video source. An error message is displayed.
- Select Work without media file.
- (Optional) Select the Remember this for current NVivo Project Session check box to work without any unavailable media files during the current session.
- Click OK.
Working with YouTube videos
A YouTube video is not embedded in the project or stored on your computer or network. The video file has a link to the video on YouTube.
You need an Internet connection and Internet Explorer 10 (or later) to play the video in NVivo. You can still work with the video transcript (if you have created one) without an internet connection.
You can work with a video file from YouTube in the same way as you would a video file containing imported media—however, there are few minor differences. For videos files from YouTube:
- You cannot display a waveform.
- You cannot adjust the playback speed.
- The video size always scales to fit the player window.
NOTE You cannot embed a YouTube video in NVivo. You create a video file that links to the original content on the YouTube website. This is a restriction that is imposed by YouTube.
