You can of course also use Azure Blob Storage as a regular Vidispine storage, including importing and storing high-res and proxy copies in Azure, as well as transcoding to/from Azure storage. This is easily achieved by registering a storage in Vidispine with a method that has a URI on the form azure://:{accessKey}@{accountName}/{containerName}/.

When doing this Vidispine will monitor and use the storage according to current storage rules. Vidispine transcoding media is proxied by the Vidispine application server. Azure storage is supported for destination of transcoded files. For formats where headers are rewritten after transcoding is done, the transcoded file is cached locally and transferred to Azure after transcoding. During transcoding, the files are available via the Vidispine API function and are served by the application server. All Vidispine codecs are available, including H.264, ProRes, VC-1 (WMV), VC-3 (DNxHD) (subject to license)

You can find more information on the different storage methods in the API documentation.
