CRF <-> VMAF training data

Training datasets behind Alice-1 - a LightGBM model that predicts the CRF value needed to hit a target VMAF score for a given video segment, codec and resolution.

File	Rows	Description
`training_table.parquet`	1,762,232	Main table. Feature aggregates -> CRF for a target VMAF, per codec/resolution.
`probe_data.parquet`	52,316	Probe-encode data. Two 2s probe encodes per (segment, codec, resolution) cell with measured VMAF + bitrate.

Schema: `training_table`

One row = (video segment * codec * target resolution * target VMAF) -> the CRF that achieves that VMAF.

Column	Type	Description
`source_key`	string	Source video identifier (`dataset/filename`)
`dataset`	string	Corpus subset (`main`, `hc`, `ext`, …)
`split`	string	Train/validation/test split
`segment_start`	float	Segment start time (s)
`codec`	string	`x264`, `x265`, `vp9`, `av1`
`preset`	string	Encoder preset (mostly `veryfast`; null for some rows)
`source_width` / `source_height`	int	Source resolution
`target_width` / `target_height`	int	Encoded resolution (720/1080/1440/2160)
`fps`	float	Frames per second
`segment_duration`	float	Segment length (s, ~10)
`vmaf_model`	string	VMAF model version
`fit_method`	string	How CRF was extracted from the encode ladder (`logistic` fit)
`si_mean` / `si_std`	float	Spatial Information (ITU-T P.910) mean/std over segment
`ti_mean` / `ti_std`	float	Temporal Information mean/std
`vmafmotion`	float	VMAF motion feature
`target_vmaf`	int	Target VMAF score (60–95)
`crf`	float	Label: CRF achieving `target_vmaf`

Schema: `probe_data`

One row = (segment * codec * resolution) with two cheap probe encodes.

Column	Description
`probe_crf1`, `probe_vmaf1`, `probe_bitrate1_kbps`	First probe encode (2s): CRF, measured VMAF, bitrate
`probe_crf2`, `probe_vmaf2`, `probe_bitrate2_kbps`	Second probe encode (different CRF)
`probe_sec`	Probe duration (2.0s)
`probe_vmaf`	= `probe_vmaf1` (primary probe feature)
`probe_slope`	VMAF slope between the two probe points
`probe_log_br`, `probe_log_br2`	log10 of probe bitrates
