well I doubt it can be told easier than this, you have to know a bit about 
video coding to understand it, it means:
"no yuv": codec does not support video output in the yuv colorspace, where 
colors aren't coded as red, gren, blue compinents, but instead as grey-scale 
luminance, red chrominance and blue chrominance. This coding requires less 
bit's then rgb and is thus better suited for video compression and also 
decompression as lower memory bandwidth is required (usually 50% the 
bandwidth of true color rgb).
"flip required": means that the image is output with top and bottom of the 
image flipped, so the video out must flip it back on displaying or you'll 
have to live in australia to see the video the right way (choose what you 
like best).
