Wann 50i wann 25p ?

When 50i when 25p?



Frage von mr-ludi:
Dezember 2008

Nabend,

unfortunately I could about the search found nothing useful.

My camcorder can record 25p and 50i.
The technical difference, I know, but what are the pros and cons of both formats and when I use what?

Greeting
Pierre



Antwort von Axel:

My standard answer to this question, and as true:

Self-test!



Antwort von beiti:

25p is useful if the final product as a full-format needs (eg web - video or movie on closing date). In addition, you can use it as an effect (as part of the movie look to 'old film' to simulate, etc.).

Whenever there is no good reason, to 25p, 50i is the better choice.








Antwort von Conducator:

Shooting at 25p brings little quieter, the moving objects Picture (because without a line jump) while the 50i has better motion resolution, ie, movements (eg synonymous pans) are unnecessary play.
Ie as synonymous with sports never 25p - always with 50i.

Technically the picture is optimum 50p :-)

... and how the members here have already written: 25p corresponds rather to our viewing habits of (chemical) Film ago, where 24 images / sec. through the "box" running. It is capable of 25p synonymous to "film look" to produce.

Because players with Skip slowly but surely become extinct, depends the quality of presentation of Motion deinterlacer from the output device. Without movement, there is no difference between "i" and "p". With movement, and especially with a lot of motion (sports), the direct image on a calculator for this:

If the deinterlacer of the output device 50 represents phase (and only then would the better motion resolution), it has every other line dazuerfinden, resulting in a very clear sharp slump leads, more than by the natural motion blur with "p".

With 50p you're right. The fact that a film look 25p generated around so I would not sign. However 50i produced a video look.

... but only if the 25p really be represented. Today's Television can best represent 24p directly, while for 25p no standard exists. 25p is only a detour on the 50i are presented, and it can (depending on the signal processing of the TV) back to the old familiar lines fibrillation lead. The other said: 25p sees on television today, unfortunately, synonymous with unmoving scenes not quiet than 50i. A full-advantage with just 24p - and as synonymous only if the Television is explicitly supported.

Must he not necessarily. It can be synonymous without deinterlaces the lines represent 50stel and every second of a half of the exchange - that is, in principle, what makes a tube synonymous. The only difference is that the picture as a whole and not displayed line by line is written. I suspect that most of today's Television with interlaced material to avoid - because they show neither a dissolution, burglary with calm interlace material, nor can they s.dünnen horizontal lines flickering lines prevented.



Antwort von KrischanDO:

Hi,

I infer correctly that if I like small sports clips (handball, not chess) wishes, with 720 / 50p'm better off than with 1080 / 25p?
Or if I, instead of a cordless screwdriver übermotorisierten vans can imagine?
Output target will always be a PC monitor his.

Christian

Absolutely. Whether the PC format will actually show to 50 phases can, of course, is another question.

I film only with extreme sports 720p/50 and the difference is enormous.

In what format are you using it?

Are several possibilities. Quicktime. Mov with h.264 and 50fps or AVCHD or Blu-Ray with 720p/50. Depending on who it should look. In the worst case, it is still at 25p or 50i convert, but then of course the whole advantage is lost.

If the output destination of the PC monitor is true - but woe betide if this is not the case. On my plasma comes around 1080 25p as synonymous 720 25p and 576 25p over rather badly - much worse than 1080 50i. So I would be careful, something still very much depends of the vision equipment.

And another question under the acquisition format is ideal - the clear, from 50p you can make perfectly 50i, even if one of 50p to 720 (ideal would be unchanged 1080 50p, but it's affordable halt virtually not at all).

If I am not mistaken, then the plasma television but synonymous artificially deinterlace. That means it poses the question what you mean "worse" understand. Is the movement "jerky" or suffer the sharpness of the image? 1080p is what the picture quality is concerned, superior to 1080i, only for fast movements are noticeably jerky 25fps halt. Have you ever 720p/50 viewed on your plasma?



Antwort von wolfgang:

Of course everyone deinterlaced HDTV - whether plasma or LCD. And yes, at least on my older HD-Ready 25p when the material is massively jerky - during 1080 approximately 50i allows smooth panning.

That basically 1080p is superior to 1080i, is a fairy tale - since 1080 when massive jerky 25p, 50i and 1080, however, a smooth picture impression leaves, then I would at this specific vision device is 1080 50i preference.

As for me I only use the device, the 1080 50i record, I have not bothered with that 50p to 720 - including synonymous? That would only make sense if the software deinterlacer and the Umskalierung losses would have been less than equal to the 1080 50i signal einzuspeisen. And apart from the JVC HD200er series because we have so little equipment - ok, now a few about the real 720 50p can. But the 720 25p JVC HD100er of the series was from this point of view, unfortunately, quite forgetting.

Yes I meant in terms of individual quality. Obviously, the fluid movement synonymous with the impression a large role.

Yes I would not want to make synonymous if I do not necessarily have to. I said if you already have native 720p/50-Material viewed.

So I'm pretty impressed of what my Panasonic AG-HMC151 delivers in 720p/50. Since I filme nothing else, look at me the whole but almost exclusively on the computer. So of course I am interested in whether the more synonymous otherwise you can play properly, so my question.

I'm really glad that we finally liquid progressive movements can record. Naturally 1080p/50 would be one more step next, but you can not have everything ;-)



Antwort von wolfgang:

No, I have 720 with 50p material is not seized. Before I some time ago bought my FX1, I had almost a 3 / 4 year on the equipment of JVC maintained, whether the 720 with at least 25p would come to us after it has long been the 720 30p camcorder in NTSC countries existed. And then only the Pro-series - and initially only synonymous with 25p. The I had tested, and of the Rucklerein was not thrilled. Then it was holding the FX1.

The 151er, I believe unchanged for interesting synonymous when I test the results somewhat disappointing to find, just what the picture sharpness is concerned - because I do not understand what Panasonic has in mind. Otherwise the device would be really worth.

I have a trial course times synonymous 1080 50p material created over the Canopus Procoder does it perfectly. Is obviously not the same as recorded 720 native 1080 50p or 50p, but you can indeed dream.
