When video is stored digitally in aYUV colorspace,Luma andChroma information can be stored either interleaved to keep individual pixel components together or as planes, keeping individualFrame components together.
Packed Formats store chroma (U and V) information forPixels either directly preceding or following the luma (Y) information for the same pixel. Because the spatial positions of all chroma samples line up directly with a single vertical position (horizontal line), chroma samples stored in Packed Formats can't be co-located (located between lines of pixels) as they can in planar formats.
