OpenCS2 Local Snapshot

This repository is an unofficial, unmodified data snapshot assembled from two public OpenCS2-related Hugging Face datasets. It contains 18,087 data files (642.29 GiB logical size). Download caches and local download logs are intentionally excluded.

File counts in this snapshot:

• 12,120 POV MP4 files.
• 5,910 per-POV tick Parquet files plus one upstream index Parquet.
• 56 CS2 demo files.

Join POV and tick data with (match_id, map_name, round, player_slot). Demo files can be associated at (match_id, map_name) level. There are more POV videos than tick files in this snapshot; absence of a sibling ticks.parquet is expected for part of the collection.

index/pov_rounds.parquet is the larger upstream index (165,270 rows), not an index limited to files mirrored here. Use manifests/all_files.jsonl as the authoritative path-and-size inventory for this repository.

Manifests and integrity

The matches_05_08* files are a legacy subset manifest covering 5,910 POV/tick pairs, 28 demos, and the index. Local absolute paths were normalized to repository-relative paths for publication. manifests/all_files.jsonl covers every uploaded data file and records exact byte sizes.

Binary content was not decoded or altered during mirroring. Videos and demos may display player names, chat, audio, or other in-game identifiers. Users are responsible for complying with the CC BY 4.0 attribution terms and any applicable game, tournament, privacy, and platform rules.
