You can submit a batch of media files to the CatDV Worker for processing by providing a list of file names (optionally with metadata) in the CatDV XML file format. You can create an example XML file in the format the worker expects by exporting clips from CatDV using File > Export As > CatDV XML File, though not all the fields in that file are used when you reimport a CatDV XML file. The main field you need to specify is the MEDIAPATH of the file to import but you can also specify additional metadata, for example:
<CLIPS>
<CLIP>
<MEDIAPATH>/Volumes/Media/Folder/File1.mov</MEDIAPATH>
</CLIP>
<CLIP>
<NAME>My clip name</NAME>
<MEDIAPATH>/Volumes/Media/File2.mp4</MEDIAPATH>
<NOTES>This is a clip with metadata</NOTES>
<USER1>User field one</USER1>
<TAPE>Tape001</TAPE>
<BIN>Bin name</TAPE>
</CLIP>
</CLIPS>
