I would like to share my experience of shooting video in xvYCC color format (labeled by Sony as x.v.Colors): here are few short clips I recently recorded with x.v.Colors (my camera is AX2000):

Colors of Beersheba

Neveh Ze'ev, Johana Jabotinsky Street

It isn’t that the difference is overwhelming (in comparison with footage shot in the causal YCbCr color space), but it’s there and you can feel it: the colors become more realistic and saturated.

Thanks a lot for sharing the video.

Interesting. Maybe it gives a better range of colors for grading or color correcting... just a thought.

My experience with xv color is that I've only sees a difference when displaying the footage on a Sony TV that has the XV capability and, so far, the difference has been as described: subtle. Using xv also seems to disable any "picture profiles" presets. (See the FX1000 manual at p. 72 and the NC 5 manual at p. 75). From the manual, I gathered that xv is mainly for highly saturated bright images such as blooming flowers.

Thanks guys for your comments.

Yes, right, theoretically speaking, to watch video recorded in the xvYCC color space you should have an xvYCC-able TV set or PC monitor. However, you can appreciate the difference between standard colors and xv-ones even without this function enabled in your TV.

It’s the same as it is with color and black-and-white video.

When watching footage on the screen of a black-and-white TV, can we notice the difference between video shot with a black-and-white camcorder and video which was shot with a color camcorder but later converted into the black-and-white format?

The answer is yes, we can. As a rule, the black-and-white encoder processing two different colors that have equal brightness will convert them into two different shadows of grey. But with the black-and-white camcorder, those colors would come out indistinguishable.

Analogously, we can see the difference between video shot in standard colors and video shot in xv-colors and then converted into the standard format.
