HVR V1E + NeoHD & Intensity Pro

[Ben Butler]

Hi,

Hoping you can help. What is the resolution of the output of the Sony VIE via it's HDMI port?

The camera says its outputing at 1920.

The NeoHD capture files opened in Vegas are 1920.

Cinform is set NOT to resize anything & capturing at 8 bit 1080 25P -> 24P.

I have seen a fair few posts saying this camera only does 1440 on HDMI.

So which is it, 1920 or 1440?

TIA

Ben

Ben,

The HDMI output is 1920x1080 4:2:2 8-bit.

When recorded to tape the signal is 1440x1080 4:2:0 8 bit.

The internal sensor/signal processing is designed for 1440x1080, and when outputting to HD it is up-sampled to 1920x1080 (there is no 1440x1080 spec over HDMI).

It is important to note that there is no additional spatial detail from the camera at 1920x1080 compared to 1440x1080.

Neo HDV can capture at 1440x1080 max resolution with 8-bit I/O. Neo HD can capture at 1920x1080 10-bit. Despite my comment that there is no additional spatial resolution when capturing at 1920x1080, this resolution is more standard for HD post-production so it is often more convenient. Also, the 4:2:2 chroma interpolation performed by CineForm upon capture, and the 10-bit files created offer substantial headroom for your post workflow.

Probably more detail than you required, but the point is your 1920x1080 capture is a wise choice.

Hi,

I have Neo HD + Sony V1 - should I set capture in Cinform as 8bit or 10 bit. 8 bit looks good on the preview - will it create 10 bit files through (what I want it to do and reason for paying extra for HD over HVR). If I set the capture at 10 bit the preview has lines all over it.

Is there a way of change the Cineform default capture mode by editing the registery or and INI file so that I dont have to keep re-selecting 25P rather the 29.97P which is a bit of a pain when I have to do it between every shot.

Kind Regards

Ben

The Intensity video mode of capture is now sticky, so it will your last capture mode. This will be in the next build (3.1.2 out soon). Currently the HDMI cameras out in the market are only using the 8-bit mode. Internally CineForm compresses this data as 10-bit 4:2:2 YUV.

The Sony Web Site:

They make the following claim:

The ClearVid CMOS Sensor™ has been developed using the most advanced technologies in the semiconductor industry. Thanks to the unique grid arrangement of the photo diode sensors, in which each is rotated by 45 degrees, sensor resolution has been optimized while maximizing the photosensitive surface area. Combining this imaging system with its associated Enhanced Imaging Processor, has enabled the use of a sophisticated interpolation scheme original to Sony and entirely different from conventional spatial offset techniques.

The "3 ClearVid CMOS Sensor" system is the core element enabling the 1920x1080p video signals. Also, unlike CCD sensors, there is no vertical smear when shooting high-intensity subjects, which further reduces shooting condition constraints.

And:

This special imaging processor has been developed to bring out the full power of the 3 ClearVid CMOS Sensor by handling the video signal output in 1920x1080p and 4:2:2 color space. Its unique signal processing separates the image data into its texture and brightness components and processes these independently. This makes it possible to reproduce images with a high level of clarity, from the very darkest to brightest areas of the image.

So while they do not come out and say 1920x1080 spacial resolution they are clearly hoping people will think so from this glossy carefully worded stuff.

But look at the specs:

http://bssc.sel.sony.com/Broadcastan...-V1U/spec.html

Picture elements Approx. 1,037,000 pixels (effective), approx. 1,120,000 pixels (total)

and it would appear they do not even have 1440x1080 spacial resolution.
That would be 1,555,200 effective pixels.

All I know is, the V1 has lovely output and when CF'd to 1920x1080 for post work, the final results are beautiful, even when projected to a 7ft x 4ft image!

Whatever Sony is doing with the V1, I hope they keep on doing it...
