# kVTCompressionPropertyKey_ProfileLevel The profile and level for the encoded bitstream. ``` let kVTCompressionPropertyKey_ProfileLevel: CFString ``` ## Discussion Available profiles and levels vary across formats and among video encoders. Video encoders should use standard keys where available, and follow standard patterns when standard keys are unavailable. ## Topics ### HEVC
