Cam works through one or more watch folders that you configure on your axle server, or on storage accessible by your axle server. To re-wrap camera files, simply place them in the watch folder. Cam will detect and re-wrap the files automatically, and place the finished file in a folder of your choosing. You also have the option to create proxy files, ingest metadata from XML, and create a backup copy of the original media.
When you create a folder for rewrapped files in the Cam settings, axle automatically adds it as a catalog. If you've enabled proxy generation and metadata import in Cam, then axle will also get proxies and additional metadata from Cam.
