Newsmeldung von slashCAM: The SonyHVR Z1 in the Test of rob - 14 Jan 2006 18:44:00 > By the Z1 has Sonyvor introduced almost exactly one years many of the long-awaited professional brother, the FX1. Since then, the Z1 has penned a similar success story, as then, the VX1000 and its successor, the professional PD150. Hardly a video rental, the Z1 does not result in the range, hardly an HD production, which does not use the Z1 as cheap back-up cam or for special shots as außenmontierte Camera. Similar to the Introduction of DV to HDV Sonyebenso has managed to occupy a relatively early stage with imported product, the market segment HDV / Professional impressive too.
Antwort von svenson:
of good quality in downkovertierung (HD-> SD), I can agree only as long as you rausschickt an anamorphic image - once the camera to compress, thus letter box "" should, it is awful. I think.
Otherwise, I agree with the test for the most part, synonymous if I am (since months with no errors obscure visual drop-outs) to wrangle, which no one can explain to me, and seems to occur during extreme lichtwechseln ....

After about 15 hours Rotate I can agree with this report fully and completely. A great camera with an excellent price / performance ratio.

1080 HD to VHS standard
Normally, HDTV has 1080 one Resolutionvon approximately 2.07 Megapixel (1920 x 1080 pixels). For the commonly specified Resolutionvon HDV 1440 x 1080 pixels, a 3-chip camera would need around 1.56 megapixels per chip. The HVR-Z1, Sony's flagship HDV, but only 1.07 megapixels usable, representing a Resolutionvon 990 x 1080 pixels. HDTV 1080 compared to the Resolutionalso by almost 50% is reduced which in Comparison with a correspondingly large projection but is clearly visible. That is) then about VHS level (60% compression. Even in the small HD 720 mode is reduced Resolutionum about 23%, since only you can work with 990 x 720 pixels.
In addition, the lens of the HVR-Z1 is not particularly strong, and the camera slightly weitwinklich Sensitive to light. Beleuchtungsbedigungen bad as it finds the amateur filmmakers often reduce the sharpness greatly.
Comparison of DV in the lower light sensitivity is a general problem of compact HD cameras, caused by the fact that significantly more sensors need to find space on the small chips.
The SonyHDR-HC 1 E, a single-chip HDV camera with 3 megapixels creates real synonymous less than 1 megapixel. Equipped with a sensor Beyer she would be able to create with 3 Mpx loose the HDV 1.56 Mpx. One wonders why this is not done. Even Sony's HDCAM system operates the way, with the exception of HDCAM SR in the 1080s Resolutionmit a 25% compression.
Antwort von deepcode:
the Z1 roars at +12 db gain less ale one DVX100 at zero gain.
look, however, a different matter ..
Antwort von Armon:
Signsoft intelliBO uses for more than a half-year with the Z1.
the pictures are good, the handling very used to. For me, the handling is a disaster.
For example: As a hand-held camera, the aperture can not change during the turn without having to blur the picture. The Aperture is much too heavy.
All the buttons are too small and too close together. Try to time at minus 20 degrees with gloves to turn. This is only for fully automatic mode.
Comparing the images with what you see in the viewfinder or on the LCD, but agrees with the cut!
In the 4:3 screen you can see more sides will be included as, although the mask is exactly 4:3. What is sony thinking there! Of these, but I have never read something in a test. But this is a huge problem and not akseptabel for this price range!

Hello,
So, I would want to see exactly on my LCD DAS, which receives the cam!
To Overscann I will take care yourself ...

The HVR-Z1E HDR-FX1 and the use sogn. Pixel Shift process. In the green CCD is offset by half a fitted blue and red pixels from the CCD. For this horizontal difference can then be twice the luminance Resolutionherausrechnen. From 960x1080 to 1920x1080 so, which is then heruntergefiltert for HDV compression at 1440x1080. Since HDV is sampled at 4:2:0 only, is half the chrominance Resolutionkein problem. Pixel shift is not a new spell but we have used for years in professional camcorders. Another advantage is that the pixels can have a larger area, which is good for the minimum illumination is prevented and Noise.
The viewfinder of the Z1 and FX1 is working with overscan, just like most of television. If you want to see the whole Full Resolution Sample, then there is in the Z1 (and only there) the all-scan mode, which can be easily attached to one of six freely-assignable buttons.
Antwort von prem:
As for the problem of the viewfinder and the LCD display of the Z1 is not about overscan.
The Z1 has there actually a problem!
It shows more horizontal than it absorbs, but not vertically. This I have checked in a professional monitor (of Sony) synonymous in the overscan!
I suspect that with the Optics, which is designed to HD (16:9), has something to do. Filming is 4:3 because a problem arises during conversion.
The camera is not filming what I want to shoot! Why this is so, I'm really no preference. If Sony knows this, Sony should correct this!
Antwort von Udo13:
Hello,
who's filming HDV in 4:3?
Antwort von Max 100:
An old experience teaches that one should never be in the market has come new products, it camera or editing software, buy immediately. To wait several months until the teething problems are ironed out. Only then can useful models come out. The competition encourages this to.
By the way was already drove in Issue 115 of Video Media is a not very flattering SonyHVR field test of the Z1. Obviously now come synonymous band still problems with the HDV system added.

who's filming HDV in 4:3? that's impossible.
