Frage von k90:
Hello,
had previously worked with a XM2 and I now XH A1 purchased. As a newcomer HDV I like a basic question:
I work with Premiere Pro 2.0 and a Matrox RT.X2. For all HDV recording is a slight "noise" or "surface fibrillation in low-contrast regions. I work with an HP 24 "LCD 1900x1200 and can accept this on the RT.X2 synonymous directly as a preview monitor use. The HDV quality with 1:1 representation is contrary to other opinion-quite-bad. Is the effect described in HDV recording normal (due by Compression MPEG2) and: you can see this "noise" on the right TVs synonymous with the corresponding resolution?
Thank you in advance for the answers!
Gruß Marc

Moin,
the A1 is not a pack from and going to film Camera.
You need only look at the camera, or this Page bsuchen and download presets. With the factory setting is nix.

Is the effect described in HDV recording normal (due to the MPEG2 compression)? At 1:1 reproduction of the original material on an Apple Cinema Display, I see at 6 dB Gain a mosquito swarm-Grisseln
in unmoving image parts. This noise is not a compression artifact, and it looks far from natural, such as noise in computer hardware, such as film grain. When movement is no longer perceive it.
For
faster movement and gain blurred transitions occur when light Posterisationseffekte (no smooth transition of light after dark, but gradually). That has probably something with the temporal compression of HDV to do. So I would not gain general permit. With good lighting, there is no noticeable CAs, neither land, nor in detail or fast movements. Pixel noise is only at double magnification to see if you and with your nose practically on the display sticks.
Wheat is right. Without the material for your post again very critical to have, I would have said, there is no noise. Now I say, the camera produces in 25p a look, for example in comparison to the FX1 immediately pleasantly conspicuous. Better detail, brilliant colors. And for someone who has umpteen times a day to photograph the grain is sharp, a nice "analog" look (caution: Subjective assessment, I am a bit biased).
In direct comparison to FX1 also produces noise. To recognize at its original size and as a rectangular pixel blocks. The Posterisation is here in the Still Image motion and high contrast (lighter flame) are very massive, overwhelmingly synonymous Scanlines 50i, far into the black sweater of the smear, the flame effects in the video subjective grell.

Thanks for the answers!
That with the presets I have thought ... Incidentally, Axel: have not rotated with Gain. Noise, which comes from the booster, I know.
Under http://www.visionice.com/download/xha1.wmv you can her a clip in 5 seconds to download format WMV9. The forest in the background and the facade of the structure in the foreground "flicker". Would be grateful if I resonance of you to acquire.
Have the intervening presets of dvinfo downloaded and viewed. Which presets using their preferred?

Antwort von WeiZen:
And what is with the presets on www.fxsupport.de/14.html?
Antwort von Axel:
The film is for me not to play clever. What makes her just always with your HD-Wmvs? WMP9 In short, I see a high
4:3 Picture (anamorph squashed) of any concrete tower on a meadow, then crashes into the tower two or three phases, looks like a series of photographs. Is this now s.Mac, which already lacks any codec, or what is going on here?
Why do not you exportierst directly from the timeline Mov than 5 seconds?
Antwort von the machine:
Do you still AGC?
Antwort von Axel:
Do you still AGC? What is AGC?
Antwort von k90:
Hello,
AGC (Auto Gain Control) is not acceptable with the presets of fxsupport I play around a bit now. The WMV is actually only 5 seconds. It was directly from the timeline of Premiere with the Matrox Media Encoder created. You may be missing the appropriate Codex VC1, if on the Mac is not running.
Thank you first, if I new insights regarding the presets I have to register again.
Gruß Marc
Antwort von wolfgang:
The export as WMV-HD is anyway inappropriate to anything on any artifacts can say. If that original m2t material. Equally inappropriate is the analysis frame in order to be able to judge something - because little about how the moving video will actually look. Artifacts found in each compressed video - you just need to go looking entsprechedn.
Antwort von k90:
Hello,
it is actually a noise and no MPEG compression artefacts. At-3dB, they are much weaker.
Now I have the presets of fxsupport made. Many settings influence each other and so I wonder how it is going to be the optimum setting to be found. Things like Color Gain, Sharpness and Noise Reduction are clear. But: Who found the perfect combination between things like horizontal frequency and detail of the detail balance. Sure try, but it is not synonymous is important to understand ...
In the MPEG fsxupport XH A1 is my demo clips Effect (surface noise) are not visible now and I would be interested with what the presets are MPEGs.

Hello,
when NR1 is set to LOW, the picture is very good. Has anyone experience with regard to the setting Nachzieheffekten in practice?

... when NR1 is set to LOW, the picture is very good. Salut Marc,
ever, the
fine tuning range custom presets that can, depending on the lighting situation quickly retrieve it? Thanks in advance.
Antwort von k90:
Hello Axel,
XH-tuner I know works very well for creating the presets. For the fine, I would either use the Canon Console (preview option presets the same software to be modified) or so I make it, the A1 via firewire to connect to the desired recording mode and in the premiere recording start. Then you can quickly s.der Camera presets to change and see an immediate picture. Works quite well.
The noise comes only when one 10cm in front of the screen sits.
