Chroma subsampling
Chroma subsampling is the practice of encoding images by implementing less resolution for chroma information than for luma information, taking advantage of the human visual system's lower acuity for color differences than for luminance.
It is used in many video encoding schemes — both analog and digital — and also in JPEG encoding.
Rationale
Digital signals are often compressed to save transmission time and reduce file size. Since the human visual system is much more sensitive to variations in brightness than color, a video system can be optimized by devoting more bandwidth to the luma component (usually denoted Y'), than to the color difference components Cb and Cr. In compressed images, for example, the 4:2:2 Y'CbCr scheme requires two-thirds the bandwidth of (4:4:4) R'G'B'. This reduction results in almost no visual difference as perceived by the viewer for photographs, although images produced digitally containing harsh lines and saturated colors will have significant artifacts.

Fast Lane
by: E-40(E-40)
[Verse 1]:
Livin' the life in the quick lane
Only the strong can survive
These streets'll swallow you up man
and eat you alive
Cain't be no poodle
Run tuck yo tail and hide
They'll spaghetti yo noodle man
Element of Surprise
It's goin' around man!
Death in the air
Better not be scared
Cause ay-henas can smell fear
It's not a lot of love but it's a whole lot of hate
Beware of your surroundings
They starving, they ain't
The lake of fire awaits for those with no souls
Hot like a stove
Hotter than hot coals
That's the thought processer of soil soldier
6's on the note and postholer, spinach and yola
I'm talking realer dope money this hustla making
(E-40)
[Hook]:
I'm deep off in this game
Wherever money and I get to it (whatchu living?)
In the fast lane [x8]
[Verse 2]:
Looking up with greenbacks on your mind is a good sign
My name ringing like a high school bell, like a church chime
This ain't chameleon, but go get a glass of wine
Listen to me preach my rhyme, sit back and recline
I'm too real to be unreal to truthful to be fake
Daddy and mommy when they separate ways when I was eight
But it made me great, more stronger and God willing
A few years later, I'm worth a few million
Top billion, killin em with my independent grip
Got rid of my digital scale and started making hits
Flipping all kind of whips visits cutlass and Lexus's
Me and the Clickers St. Charles, God was blessing us
Successfulness, all praises due to Allah
Jesus Jehovah the most highest almighty God
Reverend Therman them other Therman I miss you much
I know you up in heaven watching over us
Get back and help people that's what they taught me to do
Can't save the world but I can help save a few
People talk behind my back laugh and smiled all in my face
Saying my voice was too squeaky and my style was a disgrace[Hook]
