## Discussion

This property is supported by the DV25/50 family of encoders. If false, content is encoded as interlaced. If true, content is encoded as progressive. The value of this property fixes the [`kVTCompressionPropertyKey_FieldCount`](/documentation/VideoToolbox/kVTCompressionPropertyKey_FieldCount) and [`kVTCompressionPropertyKey_FieldDetail`](/documentation/VideoToolbox/kVTCompressionPropertyKey_FieldDetail) properties.
