some details:
shot with dvx100b (25p) f6, saturation turned down to -7, master ped +3, everything else factory f6 preset. yes, i know it makes look flat but its better than blocky colors :) used F~2.4-3.2...can too open iris cause that stuff?

i have had that same stuff in some highly detailed shots too. for example alots of trees. never had this problem with my older cams, dvx do this only :( i love dvx's look (!) but its picture clarity isnt the perfect one :(

but back to those clips: i got curious what causes that, i dont want to ruin anymore my shots with this stuff, can anybody please help me?

thanks!!
 
are you talking about the stobe-ing ?
it's when there is high contrast changes (black and white checks)
that are as small/or smaller than the lines of resolution in the camera.
 
yes strobeing is that problem..

joshua: should i put detail/v-detail more blurry or more sharper?

my canon optura 20 and gl2 has never shown this kind of stuff in similar type of situations. does dvx have lower lines of resolution than those cams?
 
GL2 is lower.

It's more detail that's the problem. Lower res cameras will "blur" that effect.

Set your detail to thicker.
 
i tried out to put v-detail thick, it seems to take off that soft glow which f6 preset is good for.. i shooted out with thick and thin to compare results, and thin seems to have more blurry/soft glow look than thick.. also thick brings out more clearly noise. thin v-detail smooths noise out..

if gl2 has less lines of resolution and blurs out that flickerin effect, shouldnt thin v-detail blur flickerin out more better than thick? and thick brings flickerin out more clearly?

im very confused now..
 
Did Barry Green's book come with your DVX? He explains it much better than I ever could.

But "thick" makes it less resolution (sort of), so the tiny details don't get a chance to strobe against each other.

But you have to watch out Deatil and the V.Detail. They affect different things. (Again, I don't know off-hand which is which...I haven't run into a situation where it was necessary...yet.)
 
no, barry greens book didnt come with my dvx :(
but actually, there wasnt any "more detail" in tiny or bigger objects in thin v-detail, only slight blur cover over the picture.. but maybe that soft blur blurs thin lines to look a bit thinner and that creates strobin effect..
