Access to Category Metadata

[MoSalama98]

Hey,

Problem

I need metadata with:

1. Category/class labels for each video/object

The meta_train.json and meta_valid.json files only contain basic video info (frames, dimensions) but not categories or challenge flags.

Questions

1. Is there a metadata file/API that provides category labels and challenge flags (NC, MS, CE, DV)?
2. How should I access it? (specific file, custom script, different method?)
3. If available, could you share the file location or a code example?

Use case: Filter out non-physical targets (NC=True) and organize remaining videos by category for manual review.

Thanks!
