Frage von Thomas Petschel:
For video recordings with 1080x1920 Resolutionmacht the EOS 5D Mark II, unfortunately ugly flickering s.Kontrastkanten (Contrasting lines, such as at windows, rooftops, railings, etc.).
The lines in the picture need not be horizontally or vertically in the motif, synonymous with oblique lines flicker occurs. It may look something like line flicker in interlaced.
At the low video resolution 480x640 the problem does not occur, or the lower one does not Resolutionsieht him.
The image errors are not yet see in Live Picture s.der EOS as soon as we have not introduced a clip, and s.der EOS happening, you see the mistakes s.der Camera.
I suspect that the image errors occur when scaling of internal 5.616x3.744 at 1920x1080, but of course not know it exactly. On the H.264 codec, it is not. When I mean taking from the Panasonic HVX200 Comparison, there are no aberrations. After the conversion of DVCProHD in the H.264 codec are also no Flimmerfehler available.
Canon to improve with firmware update??
Or are we not wiedermal the non plus ultra??
Maybe someone knows a solution?
Many greetings in our forums!
Antwort von B.DeKid:
Well, we're probably still not in Non Pros Ultra ;-)
No clue hear them the first time
Alternate views Sampels online.
Nen update if that could resolve the aforementioned Prob, you have to just ask Canon,-P

With what you mean film lenses?
Antwort von carstenkurz:
It is well known that the Canon has an extremely underdeveloped scaling mechanism. The need to reduce in real time at 30fps on their 21Megapixel tenth for HD, without having to have adequate computing power. So you have to dodge. It's possible that Canon with the 5D because some days later is doing something to it, but otherwise seems to 7D outset because of better equipped. In this regard, I have seen but still no real comparison shots.

I film with the included kit lens Canon EF 24-105mm 4L IS USM, then the EF 70-200 2.8 L IS USM (with the selective focusing is super-lock) + EF Extender 2.0 (for even more of Deep Field), and EF 16-35 2.8 L USM (for stand up or steady hand, since no image stabilization is built). Sound via external Micro Shure VP 88 (condenser, stereo) Since image stabilization in lenses with IS always hums, is an external Micro essential. Unfortunately, the microphone input of the EOS 5D Mark II roars very strong, this is a denoising in the audio editing software is necessary.
Antwort von MarcBallhaus:
This is known as Alias | Wavefront Mayaing and it is really old hat. Screw nen soft diffusion filter in front and is good.

Antwort von meawk:
Soft diffusion filter - which was good. Exactly!
Take the cam to take pictures and buy yourself a good Film-/Videocam weeks ago I would have sarcastically said, but now that I may still reflect a purchase, I say that any more. . .
Antwort von MarcBallhaus:
But why shoot the people with one bescheurten Kit Lens Aperture 4.0 for me will probably always remain a mystery. For the money this is costing the optics, you get 4 lenses synonymous with significantly higher intensity on eBay.
All strengths of the action makes with this strange illogic immediately niece, because it gives away the extraordinary sensitivity to light and through the smaller aperture, the unusually high synonymous Bokeh - the only two strengths of the action.

Absolutely right!

Alaising wirds meant to be. Thanks for the hint. According Heliopan UV-IR cut filter to bring help, have tried, but it is unfortunately not so. Anti-Alaisingfilter or soft diffusion filter to alleviate the problem sure (have not tried it yet), unfortunately at the expense of sharpness. Max.Bildschärfung) When setting sharpness s.der EOS at 7 (edge flares is extreme, when set to 0 (minimal sharpening) have significantly alleviated. Unfortunately Picture impression is then somewhat blurred, which is not the point of it.
For "normal" shots, I think the kit lens suited quite well at high ISO brightness 4 and I get usable photos, which in Comparison to the Panasonic HVX200 at +6 Gain and Aperture 1.7 is almost all black. The kit lens has IS, stabilized better than HVX, except it moves too fast with. For sharpness / blur Like Hollywood, it is of course nothing.

Anti-Alaisingfilter or soft diffusion filter to alleviate the problem sure (have not tried it yet), unfortunately at the expense of sharpness. A UV-IR filter will not help you with security. Where should I stand? Of course, a soft diffusion goes to the sharpness, but not negative. The Alias | Wavefront Mayaing is produced only because not every pixel is read from the chip, but only for the alleged Resolutionbenötigten. The sharpness is so anyway "not real", because pixels are missing. It is like a painting that is incorrect without interpolation (=) digitally reduced. With a soft diffusion du counteract positive and take the digital harshness out, but you do not lose really s.Schärfe.

Do you think sharpening polishes the lens? It increases the contrast s.den edges, precisely what makes each measly digital sharpening otherwise synonymous. This parameter, of course, belongs to zero, as other s.jeder Camera synonymous when one does not revolve grad ne reportage. It distorts your picture.
The 5D creates approx. 550 pairs of lines which it creates, regardless of what you s.dem controllers rotate the avatar. But if that is too blurred, you can help the controller is not synonymous, because he lied to you only.
It is nachzuschärfen much smarter in the post to the relevant Full Resolution Sample, it looks a lot better.
For sharpness / blur Like Hollywood, it is of course nothing. Yes. Because of the full-frame sensor the Cam creates even a bokeh that does not synonymous, and no Arri Red riff. If you Billiglinsen and visors with 2.8 and up the road, however, are not.

The image errors probably call themselves "moiré"

Antwort von carstenkurz:
Moiré is a grid overlay. This is the Canon as I have said more Alias | Wavefront Mayaing-effects due to the poor scaling / filtering.
Diffusion filter with a suitable one already comes next. The right have produced uncertainty in the field of film / photo resolution, and should be in the area of the FHD video resolution is only slightly softer edges.
Actually have to sit most of the good DSLRs such filter ( 'OLPF') already on / in front of the sensor, because of course synonymous s.FullRes signal such effects occur. Only the very cheap for the FHD Resolutionder Canon runterskalierte to 'fine' as to lead to something else.

Wrong. Let's tell you something. The test can forget you.
