Color-bars-vegas-dv.png (605 × 93 pixels, file size: 970 bytes, MIME type: image/png)

Description
English: This image demonstrates luminance shifting as a result of chroma subsampling. Image was generated from Vegas using it's color bars. It was shifted one over to get the chroma subsampling happening (i.e. the transition doesn't straddle the 4:1:1 sampling). Vegas' DV codec does some filtering on encoding, so this is not a 'pure' demonstration of chroma subsampling!
