Update video encodings and native dimensions (1/1329)

Standard SDR H.264 Main4.0, 8-bit YUV420 / BT.709. Native image dimensions, frame counts and timestamps are retained. Action/state data and existing source qualification annotations are unchanged.

 Episode provenance and original diagnostic labels are retained in [meta/episode_provenance.jsonl](meta/episode_provenance.jsonl) and [meta/qualification.jsonl](meta/qualification.jsonl). Signal origins and alignment are recorded in [meta/component_origin_index.json](meta/component_origin_index.json) and [meta/alignment_conventions.json](meta/alignment_conventions.json).

+In progress: 1/1,329 videos in this encoding update. See [encoding manifest](meta/video_encoding.json).
 
-Videos retain their source camera resolution. Synthetic black padding is removed without resizing camera content; examples include 640 × 480, 1280 × 800 and 848 × 480. Actual per-episode dimensions are listed in [video dimensions](meta/video_dimensions.jsonl). Spatial dimensions are `null` in global feature metadata when episodes have different sizes. The portable loader resolves a selected episode's concrete shapes in memory. For mixed-resolution training batches, explicitly configure your model's image preprocessing or group episodes by resolution; padding is not reintroduced by this dataset.
+Videos use native camera rectangles, including 640 × 480, 1280 × 800 and 848 × 480. Actual per-episode dimensions are listed in [video dimensions](meta/video_dimensions.jsonl).

-RGB H.264 streams with unspecified color primaries/transfer tags could render green in Chrome. Corrected files declare full-range RGB, BT.709 primaries and the sRGB transfer function. Every corrected video is fully decoded and its retained RGB pixels are compared against the previous release, with exact equality and unchanged frame timestamps. Some unaligned crops require lossless RGB re-encoding; most files use stream-copy metadata edits. Numeric action/state data, task identities and original qualification annotations are unchanged. This repair is presentation validation, not new physical-success or owner approval.
+Updated videos use MP4 / H.264 Main level4.0, 8-bit YUV420, limited-range BT.709 SDR with web-optimized metadata placement. Encoding includes normal chroma subsampling and quantization. Frame counts, timestamps and native image dimensions are retained. Numeric action/state data, task identities and original qualification annotations are unchanged.
 
-The previous presentation remains available at revision `cfdc72460733616ad216db60410d2c49dbf4e832`. There is no archive to unpack on Hugging Face; the files under `videos/` are individual MP4s.
