@dirtmaxim are the contents in /metadata used to label the mini-scenes? when I run track_extractor.py its creating the mini-scene videos clips but not /metadata or /actions. not if this is an issue, or what /actions is used for. thanks!

@jennamk14 /metadata should contain a timeline image and a file to generate the image. /actions is supposed to be empty. This folder should be filled manually with annotations for mini-scenes if you want to create a behavior recognition dataset in Charades format.
