Why no V DETAIL

V Detail really only does anything for you on certain images.

Keep in mind also that "0" isn't "nothing." The range goes from -7 to +7 (I think it's still 7 on the AF100; if it's a different value high and low, the principle is the same), and 0 is the middle setting. At -7, there's no enhancement. At +7, there's maximum enhancement. At 0, you're in the middle.

Thanks for that and yes, I did know 0 was default. What type of images does it do something for and is there a bigger drawback than DETAIL. Wondering why people who are using detail +2 are using V DETAIL of 0?

V Detail only affects images with a lot of vertical detail, but not much horizontal detail. Like, maybe, a ladder or a Venetian blind.

OK, but hen I look around the world I see a lot of verticals as horizontals so if it has no side affects worse than DETAIL would it not make sense to have it the same. Maybe we are all vertalist;). also what happens to lines that are neither, or even circles. Would not setting both be more likely to sharpen there edges?
 
Would V Detail also be important for skyline shots in the background of say scenes with a detailed downtown in the background? i.e. glass windows, lines, and details of skyscrapers

I had a look at https://eww.pass.panasonic.co.jp/pro-av/support/content/guide/EN/AG-HMC150handbook_e.pdf and it has a chapter on detail. I have noticed some pople are using +2 for DETAIL but no one seems to be using above zero for V DETAIL. Reading the above it kind of seems having them both the same makes sence?

Well, I grew up in the days of analogue cameras with totally separate adjustments for V and H detail - the link you quote indicates that for this camera it's a bit different. An overall detail level, then the "V detail" affecting the balance between horizontal and vertical line sharpening. As the book puts it: "If the balance of resolution between horizontal and vertical seems to be unmatched, adjust "DETAIL LEVEL" first and then adjust the "V DETAIL" level."

So yes, normally you would want them to match, so normally leave the V detail in it's default "0" setting.

But whilst that may be true for progressive video, then think about interlace, and how the enhancement works in that case. (And most broadcast TV, even HD, is probably still interlace, though it varies by genre.) With an interlace system, too much vertical enhancement can give rise to an irritating "interline twitter", and controlling that may be a small price to pay for the softening on one axis.

But most important, do realise that "VERTICAL DETAIL" means "operates in the vertical sense" - *NOT* "effect on vertical lines"! In other words - and maybe confusingly - "VERTICAL DETAIL" affects the apparent sharpness of *HORIZONTAL* lines!

In the good old days of broadcast analogue cameras with CCUs, "V detail" was achieved with two delay lines of a TV line duration each, "H detail" with two delays of much less than a microsecond.
