Newsmeldung von slashCAM: Advertising with Nikon D90 clip of rob - 20 Nov 2008 09:36:00 Martin Crespo has a fairly sizeable advertising / promotional clip with the Nikon D90 for Henkell rotated. Used Nikon Lenses were 400 2.8, Nikon 80-200 2.8, Nikon 50 1.8, Nikon 17-55 2.8, Sigma 10-20. According to the director came S.2 filming days 60 min material, which average 20 days required. In YouTube quality is the clip

The Nikon costs synonymous, however, only half and the majority looks at the whole theater s.Ende in Pal to. Although I have a FullHD monitor synonymous in the bedroom, but 99% of the programs running in Pal :-)
The same problem has more than 2k Red. needed None really ....
Antwort von SixFo:
So I must agree with the critics here. Booyah! A movie, with the camera rotated nem ... was really great. The Reverie clip, however, is a monument! Give me a budget, the girls from the clip and I am turning to you the same miniDV just as much ... and DoF was not (is perhaps s.schnellen cut, but nothing is what amazed me).

I wonder more why Henkell rotates a movie with his camera? You had to rent the camera for 2 days to save?
Are we already there, the commercials are synonymous loss, as expressed in the television industry is almost normal?

Antwort von rainermann:
I would simply say Henkell shot the film on a camera, because it is now "in the talk" and are thus once again a full promotional pack more attention getting.
A year ago it was the Red, which had raised a lot - there are now cameras like the D90. What may come next year? Scarlett or something from an entirely different corner?
Who here writes disparagingly, the whole could be synonymous with a normal camera hinbekommen, did not understand what it is.
Namely ultimately absolute pioneer and a very big technical hitch to the front! Reminds me s.die Scoffers 2 years ago with the Red and laughed about a colleague of me blaspheme, because he is 1000, - dollars for a CameraLink angezahlt was that it did not exist.
Currently he is preparing 2 (!) Films, where he makes Camera. With his own red-equipment and laughs now about the "left behind" with its dinosaur technology.
I give it to him!

Yes, and you can all see the pictures? I can not. Yes, because I do not see a big difference to a spot with a "normal" camera.
That alone for me is already an enormous step forward. I myself Fummel so synonymous with my EX1 and the Letus adapter and various film optics rum - of photo-optics to film optics. And when I see what this ollen with 900, - (+ Lenses) camera now manage that one hand in his pocket can support, I say only "Heidenei".
And yes, so great (especially in the cut) I found the spot is not synonymous ... because we already agree ....
Antwort von ruessel:
Yes, because I do not see a big difference to a spot with a "normal" camera. OK then, we agree that I felt with the HV20.
Last week I was able to D90 material on a 5 meter canvas view (SonyFullHD Beamer), 95% of the material shown was for a ton and showed only painful sharpness with partially pulling heavy "Optics breathe," of the bad codec and the constant brightness fluctuation times apart. But two small samples were truly outstanding, in the film look very similar, no idea whether these were handled ... they come from the D90 Vimeo Channel.

The main theme back.
The press office of "Henkell & Söhnlein" has given us the following
Searching for our telephone station:
The above clip using Nikon D90 was in Paraguay under the Directing

Antwort von MarcBallhaus:
So, I feel the Getummel to the D90 much against the grain, because I think it is now designed for.
I definitely do not think that the clip with the D90 has arisen because it is completely illogical. Illogical because the clip is sure to 150,000 to 250,000 EUR has cost. I count a bunch of young actors and extras, costumes, fireworks, road blocks, hotel lock, lighting, Gripper, and a competent cinematographer and and what should these expenses with a poor camera jeopardized? It burns not a single highlight, here schwobbelt nothing, the edges do not have the typical stair-D90.
Each of the D90 ever had in his hand and tried to order a movie to make, do what I'm talking about. The D90 is catastrophic and has blurred staircase formation of diagonal lines, and is so intense that they still synonymous with a reduction in this size would have to be seen. The overall uncertainty can not be made synonymous to the Compression her move, because if you want a decent 720p picture with the same rate in MJPEG compressed blocks, while there has been training in the area, but is s.den ratten sharp edges.
In addition, everyone knows advertising turns, especially the customers great value on big cameras and big lenses specify precisely Henkell and no preference should have been? I think all that for a bad marketing gimmick and find it sad that so many fall for it instead of the times things critically.
For the rest I say that the D90 is not HD, but any similar material hochskaliert SD. Any doubters should a Siemens star with a D90 filming this to PAL again downscaling to 720p and the results compare with the original. The same process then please with a real HD camera, and then compare synonymous.
I wish much fun with the enlightenment.
Nikon should be more energy put into the technology than in questionable marketing. For me, these actions are a reason to sell everything on it is where Nikon and Canon to change, because I come to me highly vermeiert before.
Toller Film unlike Reverie. The story has a beginning and an end. The Nikon does do is "720" and makes the Canon "1080".

The same problem has more than 2k Red. needed None really .... A misconception really hurts and renimmierten in such a forum must not remain uncommented. What does it mean for Full HD, so 2k? It means that 1920x1080 pixels with 8 bits (HDMI) so YUV 4:4:4 sampling displayed. Call me a CameraLink which can?
Right. There are none. This creates only the film scanning. Have you ever noticed that movies always somehow better "look as the best TV recording in so-called Full HD?
The Consumer HD Camera from the market makes Blöd 4:2:0, and even the SonyEX1 can only be 4:2:0, ie, only at a scaling and interpolation to 495x270 pixels, that is not even SD, you have the full color - sharpness and detail that your HD Television can. This means, conversely, that you are in 4:2:0 Farbsampling the 4x Resolutionbrauchst to fully auszureizen Full HD, so 8k! Or just 4k for 4:2:2 sampling, and exactly what makes the RED One. The Scarlet is a little bit more so that you can then Nachkadrieren or zooming without having to lose s.Schärfe, incidentally, another reason for more resolution.
Do you still believe that no one needs more than 2k?

There are a number of cameras that can record uncompressed HDTV. The Viper, the next and so Origin: http://de.wikipedia.org/wiki/Digitale_Kinokamera#Die_relevanten_digitalen_Kinokameras_und_ihre_wichtigsten_Eckdaten
Apart from that, "2k" not identical with "1920 x 1080". The fact that films look better, has less with the sub-scan video, but rather with the chemical properties of the film material. For film-look is much philosophises. If all is the chroma sub-sampling a small factor in why film looks different than video.

For film-look is much philosophises. If all is the chroma sub-sampling a small factor in why film looks different than video. Nonsense. Digibeta is synonymous to PAL uncompressed. But does not uncompressed 4:4:4, but in the case of 4:2:2 Digibeta. And just because the film is chemically different is designed, it does not look much better. I know a lot of the movies look like shit anyway. Ucompressed refers to the data after the sampling.
Reducing yourself on the facts rather than on Philosophizing: = 4:4:4 film scanning, video = 4:2:0 or 4:2:2 or 3:1:1 ... and the Full HD is not exactly 2k is just about, I know perfectly. No worry. It must be synonymous clear that a picture that of 4k scaled down to HD was simply s.Informationen has more than one is the right was filmed with HD.
Philosophy or rather advise you only if you do not know better. I'll show you some of our productions, where you'll never come out so that it is rotated. Film Look is primarily a matter of experience. I have much synonymous incredible 35x stuff Free people of talent seen the man with a video camera would be better achieved. So simple is not.
If we are the best of 60 minutes to see material I find that while in principle not a bad ratio, but two full rotation days? So for scenic work in advertising are 60 minutes for two days filming joke. We miss usually 120-180 minutes per day, and that at a ShotList, the attention to detail is prepared and a team that is recorded. That makes s.zwei days five to six times its. Again, this is any indication, the spinning of the truth with very secure has nothing to do.

In addition, the "specialists" are not even managed to turn off the automatic exposure. This is probably synonymous clear that the DoP was not.
A better solution is there only the choice of the brains, because there was something that represented what makes her, car-rig, Steadicam. That's all. The rest of this whole movie is bloody amateur level.

@ Marc ball home
Marc, I'm in the majority opinion of your score, but a few corrections are needed:
Digibeta is synonymous to PAL uncompressed. False, DigiBeta features block-DCT-compressed component video signal with a 10-bit YCbCr 4:2:2 to (compression 2:1) ... this is far from being uncompressed, otherwise it would have to fact (including vert Blank 270 Mbit / s to record, however, is: 126 Mbit / s). The D5 stands for transparent and uncompressed.
(BTW the RED is not synonymous to uncompressed)
Digibeta is synonymous to PAL uncompressed. Again wrong: Digi Beta PAL is not on, but an SD signal according to ITU-R BT.601.
PAL is an analog method, Beta SP PAL has recorded.
But does not uncompressed 4:4:4, but in the case of 4:2:2 Digibeta. uncompress has nothing with the color to be done.
The perk here is confused with "transparent" and is transparent, in fact, only 4:4:4, synonymous if the relevant prospectus happy 4:2:2 as "transparent" call. It is wrong.
Each sub-sampling, ie synonymous 4:2:2 is the reduction of data, no preference, be it digital, or analog is happening. In 4:2:2 are already 50% of Farbinformtionen omitted, ie reduced.
4:2:2 can thus no longer transparent. (Signal content-no interface transparency)
that of 4k scaled down to HD was simply more s.Informationen has. The richness of detail of an image is always in accordance with the resolution of the lens.
A Picture, whose origin lens for example, 100 lp / mm resolution on the sensor block dissolves detail has the identical content as a 100 lp / mm lens on a sensor unit of the x-fold higher dissolves! Only that the Moire on the higher-resolution chip is stronger!
And in addition to scaling down all high details (as they should be present), is lost.
A herabskaliertes 4k to 2k has less detail than a content natively in 2k (without Farbmosaikmaske, ie 3-chip) recorded 2k Picture.
Unless, of course, on the 4 K chips, a windowing made.
Each image interpolation leads to deterioration.
Added to the problem of Objektivgüten for 4k, because Lenses in the area around the 250 lp / mm should not everyone in his suitcase and have only law can not pay.
Picture qualities are very largely determined by the pixel pitch and less on how many pixels on the sensor are.
So when comparing images with each other, which succeeds only if one of identical values in the Pixel-Pitch out.
The disadvantage of the 4k are synonymous with respect to the mentioned Moire formation and thus the necessary filtering, as well as with regard to the requirements of the optical mapping errors .... all problems which arise when 2 k is not in the sharpness and thus provide better images to contribute.
I donated my time here the problem of non-visible light sensors with large minority ...
So you can not just say, 2k or 4k were better.
It is always important to ....
This means, conversely, that you are in 4:2:0 Farbsampling the 4x Resolutionbrauchst to fully auszureizen Full HD, so 8k! Or just 4k for 4:2:2 sampling, and exactly what makes the RED One. The bill I did not understand and recognize the connections do not.
The sub-sampling can not be a linear relationship with the resolution Bring ... or have I misunderstood something?
The Scarlet is a little bit more so that you can then zoom Nachkadrieren or without equal s.Schärfe to lose. When zooming you'll always lose considerable sharpness (interpolation). Unless your target format is no longer the original resolution. (So if you come from 4k and 2k a product creation).
Then it is no longer so, but the sharpness is

The hype around D90 & Co. is synonymous but simply be sure that we are after all an affordable HD Picture yearn. Not because it is not in reasonably good quality already exist, but because we could have for us in the affordable price regions wish. Not many of us are working with 'its 60.000, - ¬ Cam.

The Digibeta with knew I could not, thank you, now I am wiser.
But that a native recording with a 2k chip will be better than 4k and runterskalieren, which I can totally agree ncht, reversed out of a shoe.
You need at least 3K Resolutionum ever Full HD to be able to exploit, because even if the chip is only the beginning of this Resolutionbzw. Number Photo Sites, you must be very vorgefiltert, so no Alias | Wavefront Mayaing arises. Moiré is not due to too many pixels, but by too few. I know that the RED for example, despite a real 4k chip Resolutionvon "only" 3.2 k, which currently sharpest Prosumer Cam, the EX1 comes to just 800, not to 1080th These are the metrics that do not rate values.
What we do is always on top, is the Abstastung. And, yes gabs as synonymous nor a misunderstanding. In fact, it is that by sampling interpolation of a bad make up, wants to say, if I with the EX1 in 4:2:0 HD recording and the size of the image by half and interpersonal polish, my result is a theoretical sampling of 960x540 in 4:2:2.

I would s.verschossenem material quantity is not necessarily synonymous in some context with professionalism put more with perfectionism, and I believe there can be advertising film and not compare, not even because you're in the film per day on average, just 2-4 minute need to be in advertising rather 15 seconds per day. At the film there is always a next scene, and you look him 1x, maybe 2 or 3 times, but in advertising, there is only one scene, and which is so long and so often on TV or anywhere else again until it hurts.
@ Tillbaer
You say it. The problem is that Nikon underprivileged us something which is not, and people running around with blinders and do as it would be totally ok.
An HD camera is so HD, HD because it dissolves, so the necessary sharpness at the corresponding Resolutionzeigt, and this is where things just do not close the case. In the corresponding test is then of a beautiful soft spoken Picture, this is just stupid.
Imagine times before, a manufacturer like Samsung LCD Television sold as HD, but they are only SD, and where just a bunch of pixels are missing. I would say that would be false labeling and all would be upset over it, except that the manufacturer is so easily would not allow. But all are doing here as it would be okay, and that's just silly and stimulates me.
It is quite cold where the problem comes, the fact is and remains, that is not HD because what comes out, but some vague crap about the still treppt. From the horrific handling times quite apart, that is when the price so get over.

You need at least 3K Resolutionum ever Full HD to be able to exploit, because if the chip is already the beginning of Therefore, I had extra 3-chip mentioned and the use of a Farbmosaikfiltern turned off. One must of course always the effective number of pixels compared to those adjusted filter actions, otherwise of course you compare apples with pears.
Moiré is not due to too many pixels, but by too few. Wrong. Moire is caused by reflection of the contrast transfer function s.der maximum line pair number wiedergebbaren.
Ideally it would be if the contrast transfer at the maximum line pair number abruptly would fall to zero.
One must therefore ensure that the entire transfer contrast (from Lens and Image Sensor) for the maximum line pair number is small enough so that interference is negligible. It grows but (s.der sealing function), if the number of pixels of the sensor compared to the resolution of the optics increases! So more pixels!
But, you're right, of course,
synonymous with drastically reduced number of pixels compared to the lens resolution (same function).
The contrast at the highest transmission through the sensor wiedergebbaren line number pair must be small enough so that no false information is transmitted and therefore requires no Moire.
We see from the fact that Lens + Image Sensor precisely coordinated to be a good picture to show.
The unilateral change of the lens level, synonymous with a ver-meintlich higher
synonymous Lens may lead to quality loss, as well as the unilateral increase of sensor resolution.

I would simply say that Moire by the regular arrangement of pixels on a sensor chip is constructed and quite in contrast to the randomly arranged grains in the conventional silver film.
Thus, it kristallmäßig so regularly bred sensor chips always have any type of interference phenomena, precisely because the individual pixels are not arranged irregularly or in an infinite number of resolution are available.

This is true for film course, because a frequency is not constant!
For video, we have but with 2 frequencies to be done and, as we all know the physics lesson, a Schwebung from two frequencies ... and that is precisely in this case (the frequency) of the sensor and the lens.
But we have not just the difference Video> <edited film to work, but the Moirebildung and their cause with different image sensors.
