High detail scene file

Hi everyone im new to DVX user i did a search on this but didnt find to much.

I film skating and i want a very high detail look similar to HD, Ive experimented with the detail levels and detail coring levels and i set the detail to +7 and the detail coring levels to -7 this looked grainy on the LCD but when I viewed it live on my computer it looked extremely good but when I went into full screen mode it was still very grainy.

can some one give me some good scene file settings for high detail shots with out the grainyness.

also i was wondering why things can look grainy on the LCD but fine on the computer or TV is this my settings or does this happen to everyone?

THANKS!
 
Make sure you shoot in 60i to reduce grain and never shoot in 24p because that generates film grain.
And make sure you bring down the color a little when you are shooting indoors and check your master ped. and make sure its not too low.
When you see it on a t.v. it looks great but with a dvx you are always going to have a little grain.
As far as the DV and HD thing is you cant really imitate HD resolution with DV period.
But you can still play around with the color to give you somewhat HD color.
I suggest take down the master ped. and turn your gamma level to cinelike v and bump up the chroma level a little for good color.
But remember you can always do some editing too:)
GOOD LUCK
 
Thanks Jdmoviemaker but i have a few more questions.

do you think my detail level and detail coring level are set a little to extreme? also what about the V detail levels?

I have already set my lcd colors, brightness, and contrast levels to match the TV but why does the picture look grainy on my LCD/ Viewfinder but not nearly as grainy on the tv or computer is there any way to make them look the same in that aspect. Thanks again!
 
I have tested this and found that you should keep the detail coring a little low maybe at 4 because if it goes too high it gets too sharp and the interlace lines can go out of sort when there is fast movement.
Me personally I keep it at -1 for the movie aspect look ( not to obtain too much sharpness in my movie ; to make it look more like film) but for your sake , keep it at least 4.
The v detail will do the same thing , if you crank it up too high you are going to have too much vert line problems.
In quick movements it looks kinda like there is some de-interlacing or large pixels that float behind the subject that is moving quickly when you have any detail level set too high.

YOUR LCD PROBLEM: Try shooting in switching into the 60i mode and then set the shutter speed to 1/60 and taking down the iris level a bit if the screen goes bright.
But this may look too bright on you t.v.
But really in conclusion on the whole LCD and t.v. issue is that a tv screen is different from a lcd screen.
LCD screens do not handle black as well as a tv would because the color and lcd lighting is different from a tvs color and lighting. I know this because I have a lcd tv and a standard tv which handles black better than lcd tv.
when I watch a dvd on my lcd tv I have alot of grain in dark spots, but if I watch the same movie on my standard tv , all the black grain is cleared up.
Its just LCD design.

Noise (it's not grain; it's noise) happens in ANY frame rate. It only seems more apparent in 24p at times because the standard shutter speed for 24p is 1/48, as opposed to 60i's 1/60, and therefore only about half the amount of light is being let in when you shoot 24p as compared to 60i. Less light equals more noise, and that goes for any mode. You deprive the camera of light when shooting 60i, you get noise. Or, you shoot 24p with a 1/24 shutter, you're letting in the same amount of light as 60i, and you get the same amount of noise.

The DVX produces gorgeous, eye-popping footage at any settings or frame rate, but you have to feed it an appropriate amount of light. Your eyes can't work without enough light; neither can a camera. Understanding how much light you need for the shot you want is one of the basics of learning to shoot.


And make sure you bring down the color a little when you are shooting indoors

Why? The only reason you might think you want to do this is because you're shooting in available light, and there's less available light indoors, so the footage is darker and therefore the colors look more saturated.

The better thing to do is to add more light when you're shooting indoors.



and check your master ped. and make sure its not too low.

It's an artistic choice, but most experienced shooters seem to prefer the master ped at -5 to -9. But it's important to understand what the master ped does so that you choose an appropriate setting.

There's really "HD" color -- it's whatever the people creating the content want it to be.

This is a good way to get a more film-like picture. :)
 
Well as far as noise goes I just got into a habit in calling it "grain".
Noise sounds like there is something wrong with a connection on the camera or something :grin:
When you have the color up too high on the camera when you are shooting indoors can also create noise in dark areas.
I have tested this :thumbsup:
Remember when you take down the master ped you darken shadows and black areas which causes noise in dark areas.
This also works with the color because when you have the master ped too low and the color too high , you get noise almost all over the screen basically.
This is only a fact when you shoot in low light:)

That's fine, but understand what it is. It's random fluctuations in your signal, so it literally is "noise" -- the exact same sort of thing which would produce "noise" in an audio signal.


"Grain" is something that happens in film because of physical imperfections in the film itself. They're not entirely dissimilar, but one is produced through electronic means and the other through physical means.

It's about the available light. More light will alleviate the problem (BOTH problems). It's not because of being indoors or outdoors; it's about the light.
 
Yes that is why I said this is a fact when shooting indoors or in low light
because it is all about available light.
Thanks for your clearing up and input:)
 
But it's not because your color is too high; it's because your light is too low. Your solution should be to add more light, not to lower the color level. Maybe it's a stop-gap solution in an emergency when there's no possible way to add more light, but it sure would be a bad habit to develop. If your footage is too dark, your first thought should always be to increase the light.
 
There's another reason why 60i is less noisy than progressive; the way an interlaced chip scans, it employs row-pair summation which results in a 6dB reduction in the amount of noise in the signal. So footage off a pure progressive chip is going to be noisier than interlaced footage (one of the few benefits of scanning in an interlaced system).
