Frage von Sören:
Hi,
have recently acquired with the HF100 the first image is captured.
Usin XP + and FXP. When playing s.PC using the software (Image Mixer 3 Player) I noticed that the windows were always the same size. (Setting: actual size)
Recording resolution is 1440x1080 or even 1920x1080.
If the low resolution Always auto extrapolated? The Picture of XP + was definitely not smaller.
Between XP + FXP and struck me in these 1st Synonymous recordings not great difference in quality. What are your experiences here? Are there any recording situations, where the quality differences should be very clear? I had already, for example maximum zoom with extra tiny details, but previous was little difference noted.
Thank you,
Sören

On a monitor for what you did the views, ie the resolution. If the monitor is a smaller resolution than your video, can it be that the two because of the "few" more or less pixels in a standardized play window, so that the difference is not noticeable.

But it can be synonymous, that the sensor no 1920 being made .... old topic ...
Age Zaubertrick ... how do I 1x 2:07 MP 1920x1080:
Answer: never, I say it.
Observation may therefore synonymous vote and even the 1440 is not 1440 but only around 1200 ... the rest is interpolation.

Can you put your assertion with facts relative to the Canon HF100?
Antwort von ruessel:
From my HF100 comes in the best mode on the same resolution as Picture of my HDV HV20/30 out, I can practice in the film mostly no difference. Only the image contrast of the HF100 is crispy and plays in my opinion, a better resolution picture before .....
According to my information, an image angelesenen chip manufacturer, a camera with only one image chip through the Bayer color requires only factor 0.7-0.8 (0.8 only with very high electronic expense) in the color of:
1920x0.7 = 1344 pixels which is expected to be the best Resolutionsein, theoretically should be the mode 1440er entirely sufficient.
Antwort von Sören:
The monitor offers sufficient resolution - is a 24 "monitor with resolution 1920x1200er.
Antwort von WoWu:
Hi Bruno,
The thing with the Resolutions is actually a very simple calculation:
If one of a 3.31 Mpix chip, it is only once the 4:3 ... Baufom These are 1576 vertically and 2101 horizontally. Usable converted to 16:9 would be 2101 again, but only 1182 horizontally vertically.
Bayer mosaic of Wolfgang goes from 0.7-0.8.
I expect more because of 0.6 in (40% loss) and come in relation to the 4:3 entire surface of 945 x 1260, because the filter is indeed on the whole chip is located. (Be the birefringent filter is used, it is 0.5)
The sticking point is synonymous with the vertical resolution.
Even if I have a 16:9 Picture 0.8 start, I am also on 945 (1182x0, 8).
The 1080 will therefore not only reached the horizontal Resolutionist and then a ratio thereof.
As it so turns and turns, 1920x1080 never emerged.
Antwort von Meggs:
Recording resolution is 1440x1080 or even 1920x1080.

Because they're rectangular pixels in the game. If it would be displayed in 1440x1080, it would be so warped to 4:3.
Since the 16:9 flag is set, the player so it is synonymous, and interpolates the missing horizontal pixels. Just as in SD.
Antwort von WoWu:
There is no sensor on rectangular pixels!
Antwort von Meggs:
There is no sensor on rectangular pixels! Of course not, I have not said yes synonymous. But I think that you know how it is meant. The Picture is playing stretched horizontally so that the 4:3 Resolutionein Picture is 16:9.
Antwort von Bruno Peter:
Hello Wolfgang,
As it so turns and turns, 1920x1080 never emerged. The file on the memory card contains clear 1920x1080, the image processor will be produced. I went there garnicht matter what input of the CMOS chip supplies, and you obviously have so Mißberständnisse arise. The image quality of this camera is in my opinion, very convincing and the camera has manual synonymous many ways unlike the Sony cameras where you can fully automatic sets.
Currently I do video with my HD camera tape around 14fach cheaper if I Prices of tape and memory card and see each other archiving to tape of the cut is possible.
Sure, I will once again synonymous to buy something new and will be with this new video - and the memory system will have to live. But at present there is no reason for me a camera change, since everything is available, the best and trouble free with good quality work.
Antwort von WoWu:
Hello Bruno ...
no question about it ... each system, with which the user is happy is necessarily the right system ... I am totally with you and the diversity of the reasons is probably as diverse as the users.
That is just as well and will continue in the future, not synonymous change.
The 1920 can be stored is quite rubbish and probably only due to the fact that the finished "FullHD" File must be given, unlike the real-time-off, where the interpolation only when the playback can be made.
Thus, each storage media synonymous its weak sides. One has to imagine the times, approx. half of the store is "stopped" with false data.
Otherwise I had your answer differently.
Can you put your assertion with facts relative to the Canon HF100? ... proboscis but probably synonymous ...
...... na, good times that we have talked about that ...:-))))
What interested me, but times would be your impression if you somehow 3MOS times one of the Panasonics in the fingers can get (and it was synonymous only for a few hours).
To the extent that it should be, mail me at times. I would have dedicated a few questions.
@ Trunk
... Please just great ...
@ Meggen
I'm sorry ... I had understood differently. Nothing for ungut.
Antwort von Bruno Peter:
One has to imagine the times, approx. half of the store is "stopped" with false data. This is very well done by the excellent results speak for themselves yes. But clearly, we get the result of the image processor is served, not what the Optics "looks" ...
Which Camera in the consumer storage of supplies of Optics memory to a 1:1 result?
Antwort von WoWu:
At present, probably not ..... Only then will the Manufacturer is not always synonymous impudent claim and are slightly more committed to the truth.
Then they do not format this HD with 1920x1080 define, but better with
"great pictures" when they do not create synonymous to deliver what it is.
For each detergent package is now the "Bear" started when a few grams less in it, as it is ..... the camcorder is nothing to remember them ... perhaps synonymous, because the Consumenten not critical enough and expensive for any money everything can turn on.
Antwort von wolfgang:
What strikes me s.dieser Talk: 1920s in the first AVCHD camcorders were pretty much all the tests that between 1440 and 1920 the quality is virtually no difference.
Since the SR11/12 and the HF10/100 has changed, here is now said that these devices, the 1080i would be entirely out. Even with Nachfoldern the JVC HD7, I have seen Testmateril, where the quality of the 1920 material was better than of 1440er material.
What explains these findings with the approaches discussed here?
Antwort von Sören:
Probably was just the pressure from the Manufacturer to the editors bigger, but at last of a significant difference to write ... ;-)
I see nothing in any case, but yes it may be only technical. Measurement methods endeavor.
Antwort von WoWu:
It remains in the basic physical quantities:
1x 3 Mpix chip and Farbmaske. It is as if someone from half a liter 1 liter of water makes lemonade .... the other half is foam ...
Apart from that people naturally tend to be synonymous to see what they see w (s) ollen ... especially the testers.
It may be that the HF100 a better working edge sharpening has. Or the picture is generally slightly contrasting.
Meet such as testers never expected to ... why not?
Otherwise I give because Sören right. Where only half a liter of it, may no longer be synonymous to come out. Otherwise, the Canon in order to earn the Nobel Prize for Physics.
Otherwise there is the possibility of synonymous yes 1440er the material to be treated slightly differently, so that even a difference is to be seen ...
Antwort von ruessel:
It is as if someone from half a liter 1 liter of water makes lemonade .... the other half is foam ... The comparison is of you? Find ich richtig gut ... is so ... Conceivably well as plastic. ;-)
Antwort von wolfgang:
No, there were some in the corresponding HD6 Pictures - mode of the 1920s was better. What not to say that the theoretical limits, but probably only that the 1440er mode was even worse. Nobel Prize is not interested in me - but the explanation for the observations.
Regardless of testers come in HF100 on a vertical resolution of 730 LP, and a horizontal resolution of 626 LP - as well go with 1080i?
Antwort von WoWu:
Per LP WHAT?
TVL / ph or LP / mm or is it now something Own?
Test results to come like that except them understands None.
Even the TVL / ph is a measurement method from a time when it still was the cathode ray and no pixels.
You could beam the electrodes with the different values of distractions and synonymous in its brightness as fairly light / dark as possible.
It came out a variety of results.
TV lines describe (by definition) the maximum number of recognizable changes made on a horizontal line (TV line) can be produced.
If there is TVL, then have the synonymous to the number of changes on the horizontals relate.
Besides lacking the size, so a ph?
Because the measurement method but still synonymous from analog time comes, covers the entire process on a square window of 75% of the entire 5 MHz range of a TV transmission.
You can see already, as measured experts around HDTV, with methods that are by definition HDTV with nothing to do and so must necessarily come to results which are comparable with NOTHING.
I share your surprise, therefore.
But maybe yes, they have invented their own values.
But even if I look at the values of the carrier bandwidth of HD conversion, this would be for HDTV (1080) 30 MHz 872 TVL / ph .... 626 TVL would have too much and if there are indeed LP, would be the 1252 TVL, so Ultra-HD.
For 720 would be 582 TVL / ph, so 730 or 626 would be far too much already and if it is Lp, then a fortiori. (However, the camcorder has no 720).
Even if the reference 27.5 MHz accepts, in 1080 when the format should be 45%, which should still be 800 TVL.
Am I even believe that now no LP The 626 TVL but are, however, confirms that the resolution far below the target (800) is.
You see, testers wursteln as to himself, and write stuff together, not with the measurement methods (except their own) correlated and certainly no values is that we compare with other methods might.
What should therefore be such tests at all?
So, as I said, I share your astonishment.
Antwort von wolfgang:
Well, what the tests s.sich, is already clear - I am interested about already, which horizontal and vertical optical resolution actually implemented. In order to get this info, yes there are testing laboratories - but should correct the already measured (which I suspect is already the case - only the details are rather unclear).
Antwort von WoWu:
Well, yes, inclusive of all mistakes, errors in video cables, PC's, Prefilteringfehler, narrowing the bandwidth and of course all optical synonymous crutches, such as edge sharpening and increase (or change the course of the gamma levels, without taking account of the S / N distance and of course, all interpolations .
So what do you measure that, if such a transfer test image (paper / Lighting), Lens, Sensor, Signalprozessing, interpolation, monitor ... actually measure?
These deserve as much Measuring self-confidence, as the President of the United States.
When a value comes out of the ninth to interpret and white curves, only to be chic, but the statement of a refrigerator, then some consumers so obviously on the table quickly withdrawn.
There are benchmarks which would allow comparison. Only dare None at present such a comparison to be made, certainly not the editorial staff, because the next advertising contract or Gerätebeistellung then delayed.
No, no, because I prefer to stay in the good old calculation. This is understandable and correct in most cases, as you can see again and again.
