Respectfully, I would suggest that it doesn't matter a hoot who goes to the cinema -- a movie is a movie no less if a viewer chooses to watch it at home on their big screen surround sound set up.

Same as a book is a book, whether you buy the hardcover or the paperback, the film industry has been forced to review a release model that saw a rigid theatre first, followed by 'second string' release to other options -- the theatre is no longer the necessary step beyond the launch; highly successful, very good films have had only 'limited' theatrical release in a handful of key cities, primarly to ensure that reviews and street buzz got started -- the dollars then generated from DVD, cable and other distribution are not just 'cream', as they once were, but now bread and butter.

I won't present a list of the 'good ones' from the last ten years, beyond saying IMHO there have been good ones -- if you really do like films, it is a shame to stop seeing them for arbitrary reasons, and even more of a shame to buy into a misleading and pointless argument that 'adults don't go to the cinema' anymore. It doesn't matter who goes to the multiplex -- it just matters that films get made, and their audience gets to see them, however they chose.

Cheers,
GB

Excellent points, Geoff, and I fully agree with you right down the line.

However, we have now drifted far off course of the original topic of this thread. I'm tempted to break out this portion of the conversation and move it to our "Awake In The Dark" forum where it's more appropriate. Meanwhile, we really should try to steer this thing back to the subject of the HVR-V1E... somehow.

Late 1950s foreign films are big because of Janus Films and their division, Criterion.

Would it not be possible to live capture via HDMI with the Blackmagic Intensity to get full 1920x1080 4:2:2 colour space uncompressed images?

I used to think so, too, but then I was made to feel like an idiot when proponents of spatial offset (aka pixel shift) explained its benefits. It came down to the putative compromise between pixel density and light sensitivity. What is rarely said, however, is that, all other things being equal (that is, chip designs and manufacturing processes/materials), larger pixels will yield greater sensitivity. But the technology is improving all the time. I fully expect the third-inch version of the ClearVid CMOS sensors (predicted to be used in the Z1 successor) to have a higher pixel count and greater sensitivity -- and yield a greater resolution -- than those of the third-inch CCDs used in the Z1 or HVX200.

"I used to think so, too, but then I was made to feel like an idiot when proponents of spatial offset (aka pixel shift) explained its benefits."

You were most likley told the overlapping pixels argument. This is a lie.

In terms of resolution, a pixel shifted sensor array behaves more like a mosaic sensor. To get higher luma resolution you must throw away some chroma resolution with post processing.

To get a 4:4:4 1920x1080 image you need 3x1920x1080 pixels in total.

No magic wand can avoid the fact that Sony are using a sensor with enough pixels to make a (good) 4:4:4 720p image and calling it a 1080 line camera. The only question is what aspect of the picture is going to suffer as a result.

That topic will be covered in my upcoming HDV@Work Newsletter.

Panasonic HVX200 (SD 24P resolution with pixel shift to achieve 720P)
JVC 100 (720 60P resolution)
CANON H1 (1080i resolution, BUT no real Progressive framerate)
Sony V1 (720 24P resolution with interpolation to achieve 1080P)

We can assume that, at least for the time being, its not possible from any manufacturer to produce a 1080 24P camcorder with full resolution sensor at the sub $10000 market. And since neither Canon, nor JVC have opted for one, its not another market trick from Sony and Panasonic to protect sales of their high end cameras.

Probably, either the sensor and/or the circuit needed for the extra bandwith, are very expensive for the asking price.

Does anybody has any suggestions about the reason of this limitation-besides of course the cost factor.

Where did you come up with 720? The sensor is 960x1080, like the FX1 and Z1, NOT 720. Yes, the HVX's sensor is 960x540, but it does a very nice job going to HD.

I was on the assumption that the sensor of the FX1/Z1 was 1440X1080 with rectangular pixels instead of square in order to achieve 16:9. Correct me if I'm wrong.

Panasonic manages to extract from an SD 16:9 sensor (960X540=518400) through pixelshift, a HD 720P (1280X720= 921600) image with a factor of 1.77 or the 1080P (1920X1080= 2073600) spec with a factor of 4.


Sony, from an almost square sensor(960X1080= 1036800, which is very close in resolution to the 720 spec of 1280X720= 921600) with the diagonal placement of the pixels attains the 1920X1080 with a factor of 2. In any case Sony uses double the pixels (although not all of them because of the square shape) so it is possible to produce a better picture compared to Panasonic.

Writing all these it dawned to me that Sony did something ingenious which also explains the strange decision to use 1/4 inch chip in the V1 instead of 1/3 inch chip which even the A1 incorporates.
The almost square sensor of 960X1080 are two SD 16:9 chips from the consumer models glued together and turned 90 degrees. Thats huge economies of scale for Sony, because he didn't have to develop a new sensor from scratch.

Part of the reason for a camcorder to use fewer pixels while using pixel shifting to compensate for that is because having to many pixels on the chip would sacrifice the low light capabilities of the camcorder. It would have been a very big mistake on Sony part if they used 1.6MP per ¼ of an inch chip.


-EDIT-
I erased this part because it was already explained in another section.
