Each clip contains rgb.mp4, depth.mp4, depth/000000.npy, timestamps.csv, and metadata.json. Depth arrays are float32 in meters, spatially aligned to the rectified left RGB image. NaN, infinity and nonpositive values represent invalid depth. The colored depth video is for visualization; use the NPY arrays for measurements. Videos use constant FPS; CSV timestamps record actual acquisition times.

The snapshot includes one clip marked failed because the recording writer could not keep up. Its 330 saved frames are retained; check each clip's metadata.json before selecting data. The initial empty session is represented by .gitkeep.

recordings_manifest.json inventories all source paths, byte sizes, clip statuses, and frame counts. It does not contain credentials.
