Examples

To upload a directory of videos, accepted file types are mp4 and mov:

recognize upload directory path/to/directory/of/videos --tag some_custom_tag

The tag is useful for if you want to organise the uploads. You can search for labels associated with the tag and you can upload files using this tag at a later stage, and they will be automatically grouped.

After uploading videos it will take a few minutes to process them all. After which you can start querying.

recognize search keywords --output results.csv some interesting words

The --output argument is optional, if ommited you will be asked what to name the output interactively instead.
