Natural and HD are styles
For Standard and Pro, metadata.enhance_style supports natural and hd. Natural reduces enhancement intensity for softer texture; HD emphasizes sharper detail. Lite does not accept this field.
Scene controls
Standard exposes metadata.scene: common, ugc, short_series, aigc, or old_film. Pro and Lite do not accept scene.
Up to 16-bit color-depth processing
Pro supports metadata.bit_depth. API Guide v2.6.0 accepts integer values 8, 10, 12 and 16 for the Professional/Pro routes. The gateway forwards 16 unchanged.
There is no 16-bit-specific duration, codec or bitrate cross-validation at the LSF gateway. Provider-profile limitations remain unverified: acceptance of the field does not guarantee that every media profile is compatible. Confirm the required media and playback configuration with LSF.
