Infoseite // HDV format in quality by 25% boost



Frage von alles:


Hello dear community, I need an exchange relating to resolution.


HDV FullHD took over a 25% reduction in the quality of bolted resolution ((artifacts, etc., are different matter)), ie 1920 to 1440 offers 25% more logically sharpness. If I but the 1440 - HDV signal artificially in the editing program by 25% in sharpness (with plugin) and boost as 1920 x 1080 render, the lack of sharpness of the HDV format again ironed out, or I am mistaken?

Greetings

You confuse a bit, HDV has fewer pixels in the written file and the Luminanzauflösung an HV30 (; HDV), for example, is higher than in some FullHD cameras.

The Optics of the current consumer is anyway rather than 1280x720 at 1920x1080. As the question arises whether the difference of 1920 1440 pixels in the horizontal can ever perceive.

... and clear, you can use any picture to sharpen, but nothing like this is better - even the impression Picture shall be subject to negative connoisseur noticed.

Look at the times Slashcam comparison test between SonyEX3 (1920px) and the Canon XH G1 (1440px) to.
Under normal lighting conditions, for me the Canon is much sharpener from.

Everything is relative. Particularly sharp!

Hm .. this was rather a bad example, because you can in the circle of the ISO test image very well see that the EX3 more Resolutionhat:

Antwort von ed-media:

visually looks much better, is often synonymous halt s.den eye and s.Screen as synonymous viewing distance.

In any case, the material I would not sharpen the gaukelt again unnatural sharpness and falls out more than normal.

Antwort von alles:

Other plugins such as magic-bullet-instant-hd and similar claims to convert the low to higher resolutions, there seemingly magic to happen to any where should the missing pixels come
because the intermediate pixels to expect that it can work.

When I became a 1440er-HDV format to render final in 1920, what happened here? (here are the missing pixels or calculated?)

Antwort von Axel:

If HDV 1080 (i or "p") as the 720p (25 or 50) outputs, one sees little difference to the original, synonymous in larger perspective. That speaks to what deti writes. Even more significant is this issue when the original pre-scaled. Man thinks, so a bit einskalieren yes 1080, I can if I will output as 720p. But really just a bit, otherwise it will very quickly synonymous the 720er version suboptimal. Whether the EX-1 real Full HD offering, is another question, in any case "more".

Bruno,
Klär me .... which has a codec with sampling to be done?

Since I am totally with you ... and not before at least 6Mpix in play, no preference whether or 3-chip 1-chip are not 2k anyway. (; times provided that the optics create bonsai ever 150 Lp / mm depict (; or the synonymous of the EX1 / 3))

@ Deti

I thought this chart is not synonymous but the overall picture with head dolls and robots, etc.
Look at the nochmal exactly, it is a good example!

Why is such a writer always an interlace image recording hergenommen (Film coil or what it should be)? The F-mode, the Canon has over a pixel-interlaced resolution loss of 11% (admittedly only for stationary subjects, while others could be synonymous to a bad Rate Still Image). The Sony CMOS dignity with "p" show a clearer difference. In addition, everyone uses a preset, or at least a White Balance, or, in the case of Canon, AEShift what the sharpness impression directly or indirectly affected. We know a warmer effect of synonymous Picture sharpness her always softer than a cold. How meaningful are these images do not. In everyday life, the EX ahead, but maybe you wanted to say, they let the Canon is not as old as you would expect.

Antwort von TiMovie:

I have now about 4 years with a SonyFX1 HDV Cam and worked for 6 months with its EX3 - there are worlds in between!

And the factory setting of a cam to assess, for example EX1 / 3 where 10,000 images settings can - I do not know?

HDV aufzublasen caused only a reinforcement of the existing compression artifacts!
