CS2 Demo to Dataset — Pipeline Output Samples

Sample archives produced by the open-source cs2-demo-to-dataset pipeline, which converts a single CS2 .dem replay file into per-round, per-player first-person video aligned to tick-level state, input and event tables.

This release is not a dataset contribution. The point of the upload is to demonstrate that the pipeline produces a coherent, reproducible archive format. Please see the GitHub repository for the recorder code, configuration options, the alignment contract, and the full documentation of the per-match layout.

What's here

.
├── complete/       # 6 matches recorded with the standard 10-POV configuration  (~82.8 GB)
└── partial_3pov/  # 13 matches recorded with a 3-POV-per-round configuration  (~30.9 GB)

• complete/ — full ten-perspective recordings, the default mode of the pipeline.
• partial_3pov/ — casual / non-professional matches recorded with only the three players with the longest expected survival per round. In casual play participants tend to die early, so capturing all ten perspectives wastes most of the recording budget on dead-player views. The number of POVs to capture is a pipeline parameter (see the GitHub repo); these matches are included as a demonstration that the archive format is the same whether you record 3 or 10 perspectives.

Video is 16 FPS / 1280×720 / H.265 (libx265, CRF 16). Each video frame corresponds to exactly four 64 Hz replay ticks. Full schema, alignment contract, and example loader are in the GitHub README.
