In case you experience issues when importing audio/video files to NVivo and receive error messages like
"File format is not supported" or
"Startindex cannot be less than zero"
you might have to update your codec pack. A codec is a software that is used to compress or decompress a media file. There are many different codecs in use today.
What media file formats can I import?
Audio
-
MPEG-1 Audio Layer 3 format (mp3)
-
MPEG-4 audio format (m4a)
-
Microsoft Windows Media formats (wma, wav)
Video
-
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)
Codecs
NVivo relies on third-party codec software to decode media files. If suitable codecs are not installed on your computer you will not be able to import some files, even if they are in supported formats. In this case you need to install a suitable codec pack.
We suggest a package such as K-Lite Basic: https://files3.codecguide.com/K-Lite_Codec_Pack_1499_Basic.exe
NOTE The link above opens Windows/File Explorer to immediately start the download. Or you can go to the K-Lite download site here: https://codecguide.com/download_kl.htm
Alternatively, any of the codec packages at this Softpedia web site should work.
After installing a codec pack, close and reopen NVivo and try importing your files again. If the issue persists, try another codec pack.
