Infoseite // Relationship between image quality and resolution?



Frage von n.d.escher:


Hello
Thank you once s.diese great page, it has helped me a lot next.
The beginner articles are great.

But one thing I have not got it: How good image quality depends of the resolution?
Specifically: since the second hand market as a once available to 4,500 ¬ Canon XL1 for under 500 ¬ hergibt I wanted to buy me such as I have read only good about you.
But then my shock: does indeed "only" with 720x576. How can it arise that a good picture?
Now I've read several times on this page, that good image quality has not only do something with the Resolutionzu, but if I can explain it again, exactly?

When I look at DV footage of an admittedly cheap camcorder for about 600 ¬ new price then look at the picture is grainy even if I only minimal magnify. If I did my full size on 24 "monitor, I can draw almost count the pixels. That would change in AUC but with a camera is not very expensive or Optics?

Synonymous have read that it is the Independent Film Makers with the Canon XL1 even movies have rotated. But at 720 pixels on big screen? Since then the pixels would be so large matchbox?

Where is my misconception?

Provides a used XL1 for 500 ¬ or a new camera for current but also 500 ¬ for a better Full HD Picture?
Is it worth even buying a cheap old professional camera, or perhaps I should invest in a current Full HD Camera?

Many thanks for your help

are asking four:

Turn what you want?
for whom you turn?
where you want to show it?
for whatever purpose you film at all? private or commercial.

These are all questions that, everything else is hypothetical:

I want to create German oak wood from the felled, I'll buy a tractor. I want to deliver pizzas in the big city, a scooter or mini. I have important papers in the original of hamburg to munich chauffeured, I buy a Swabian stuttgart from mini-Feuerbach.

And another thing: the technology is only means of transportation, synonymous though many here do not admit it. decides the content. which can be bad, then the most expensive camera synonymous change nothing to it.

The relationship is not direct. Resolutionist Pixelzählerei, quantitatively. It is also important to note whether each pixel that is writing a camcorder into a video frame, a pixel in the scene recorded equivalent. The answer is no. Average Full HD camcorder can dissolve about 720p. But that is in Comparison to the XL1 DV very much. It would be purely nominal schonmal twice as many pixels. But one expects of interlaced DV to the real and the lack of 16:9, calculated to four to five times as many pixels.

SD is fine for YouTube with 240p or 360p or even if you only have an analog tube 4-3 at home and you never synonymous want HD TV purchase one. Relative to the modern display devices is so important to the resolution.

The most famous example is Danny Boyle with 28 Days Later. He has so synonymous as one of the first DSLR used for Slumdog Millionaire. A philosophical background is synonymous, namely, that man with simple means in the design is free, just independent. Orson Welles is quoted as saying "The enemy of art is the absence of limitations." That means that we con-and Prosumerheinis have very good conditions to create art ...

A very large screen would have a width of - say - 15 meters (am a projectionist). An individual pixels (somewhat mitigated by the fact that it is round and similar in each frame by the random arrangement of the crystals slightly offset - EDIT: Additionally, would a pixel by four to five photo represents grains) would have about 2 inches in diameter. As the relative viewing distance about equal to that that you would a modern TV einnnehmen before, there is no difference.

Then there were as at 28 Days is the possibility to use other lenses and the external DV footage recorded as uncompressed. There are professional lighting, there are methods of dealing in post-production friendly with the footage, the whole thing.

I highly recommend the Book DV Rebel , see how far the quality unbefarften user is away synonymous, and how it can be saved. After reading it you will laugh at pixel number of camera manufacturers as a selling point just yet - but you probably still buy an HD camcorder or a DSLR ...

Antwort von Frank B.:

The image quality is determined of a number of factors. One is the Resolution. Sweeping a statement, the higher the resolution, the sharper the picture. An SD (standard definition) - Picture is blurred or pixelated as a HD (high definition) - Picture. This of course will only be available if the Picture is considered synonymous to a high-resolution screen. That is, the chain of recording, editing and presentation must be kept in HD. In the case then an HD picture is much sharper than a SD picture. If the films are used only for Demonstrations on a website or on a Röhrenferseher or to burn to DVD, it may suffice to standard definition.
I personally, however, today no one more, the acquisition would recommend a camera in standard definition.

Antwort von Pianist:

Perhaps we should mention that belongs to a good image quality is not only a good camera, but synonymous a good front of the camera lens. The camera can take up so only what comes through the lenses. This is often the first hurdle. And then synonymous crucial, as the camera follows the processed signal. The pixels alone do not tell the whole story.

In the imageable input dynamics, the noise ratio, probably synonymous to color fidelity and in any case the manual adjustment of the XL1 will be very superior.

In the resolution, depending on which HD camcorder you choose current, inferior, more or less clear.

Hello
Thank you very much for your answers.
Helped me a very next.

My Conclusion:
Old Canon XL1 despite very good quality time today to recommend no more.
Cheap Full HD cameras take any more.
So rather save on a Panasonic HDC 700th

Is this correct thinking?

Greetings

Do not think that this might work properly. As already mentioned next, it comes out s.für what purpose do you want to buy a camera.

My private holiday movies that I have 15 years ago with my 110E-SonyPC Mini-DV mill rotated, have nothing of lost its charm, simply because they were rotated in 720x576. I look at the still gladly. Best on my tube, because DV is simply a 4x3 SD signal and I can not complain about a muddy picture.

I think you can not just make sweeping, SD is not good, HD is great.
For example, watch DVD's, who are SD, not just synonymous grottig clever beeen at HD screen, if the scaler has a decent built.

If the budget is limited for the camera, I would rather take a very ordinary DV-mill, all the technical data. Freedoms provides as a HD Handycam, which is limited in its operation and equipment.

For as above synonymous written before, the quality of the film / video is not in the camera, but behind the camera.

young man - as you unfortunately do not say what you plan to tapps obscure the speakers in an advisory capacity. shame really.

but just put your egg and say, turning what you want!

photographing you have a theater group that wants to control their services later on the monitor?
will you be creative? Do you travel by other countries?
where to run your art? berlin on Vimeo or on the tube tv with mama or cinemax palace?

if you want to engage in the visual manual, I advise you of so nervous filming can of Coke (the shape). you need lots of extra to buy accessories that to some extent to work with. pfrimelige mini switches and a lack of wide angle and so on are really annoying.

The content will decide, not the camera. and if you want to work technically, buy panasonic dvx 100 ne be ne or sony pd 150 for 1000 euro. you will have to work s.professionelleren more fun.

now all will cry hd-trailer.

The old man

4:3 DV turns and see Staring at the tube-tv.
