Seitenverhältnis von 4:3 in 16:9 wandeln.

Walk in 16:9 aspect ratio of 4:3. "Mixed approach" sought



Frage von newsart:
Juni 2009

Hello,

There are indeed different ways of 4:3 to 16:9 WITHOUT bar on the left and the right to change.

Either one makes an image area, then parts of the image fall away s.den photo pages long and there is a decrease in quality.

Or you can distort / stretch the image, then oval, round objects and the display is unnatural.

Or you can combine both methods.

To my question: There is a percentage, to the stretching of images of the human eye does not notice. How much can I stretch, so that is not visible?

And there are obviously (methods, equipment / software) that do not stretch the picture evenly, but the edges more than the center. So people who are usually placed more centrally remain, of course, and the lines fall on wniger. The eye is tricked, so to speak.

Does anyone know these techniques / equipment / software, which enables not only simple Sterecken and / or clippings?

THANKS

Do this at its eye. Some people do not fall on it anyway, because they rolled their 4:3 program watch on the 16:9 TV.

IdR does not come on so much when landscapes are shown, total, etc.. When people contribute very bold, which falls immediately - even if it's just a little.

I know so far only from Stillimage software and in theory, there would be no problem applying it synonymous to moving images. BUT that would be noticed if it is really strong swiveled around. Then it looks like a tunnel effect (; similar) as a very strong wide-angle lens.



The best way to generate from 4:3 to widescreen from the Ranzoomen. So it synonymous to the sender. Then they just cut straight into the heads, but that's still better than fat people get on.



Antwort von david2:

You often hear that 2. .3% (not really noticeable, it can synonymous) only occur in one direction. But if you find it has a circle head for ever.

I know that the new Photoshop (CS4 function with the zoom, without counting such people with) has, one would have to stop with individual pictures.

Always comes to the target group (; what you want to object to how big is the Buget, etc.) to.





Antwort von actvideo:

If you want to pull up 4:3 to 16:9 you need the Y-axis scale factor of 1.333 at.

If you want to push 16:9 to 4:3 letterbox you must scale the y-axis by a factor of 0.75.
