Ron Wilber · August 24th, 2009, 10:37 PM

does nano flash capture x.v.color data? Also, anywhere in san diego I can rent one?

Dan Keaton · August 25th, 2009, 03:39 AM

Dear Ron,

I will obtain an answer to your first question about x.v.color. I believe that the answer is no.

Video Equipment Rentals (VER) in Los Angeles rents the nanoFlash at this time. They have multiple units in stock and I know that they have been rented out to locations all over the country.

Abel Cine Tech in Los Angeles and New York City both have nanoFlashes. They are are not currently listed on their websites so a call is in order.

Wexler has Flash XDR's for rent and may have nanoFlashes in the future. Their business model is to have equipment based on customer's demands. They just completed the "vetting" process for the nanoFlash, so a call is in order.

Individuals/Companies in San Diego have purchased them, but I do not know if they rent them or not.

Indiegrip.com on the East Coast also rents nanoFlashes and Flash XDR's. They handle "last minute" requests if at all possible.

In the Northeast, Jeff Silverman of Inertia Unlimited Ltd. rents nanoFlashes, www.inertiaunlimited.com. Jeff has multiple nanoFlashes for rent.

Roscor may or may not have added nanoFlashes to their rental fleet at this time.

Rule in Boston rents Flash XDR's but does not have nanoFlashes in stock at this time, as far as I know.

Camera Department in Toronto and Vancouver and Department Camera in Montreal have nanoFlashes. I do not know if they are in their rental fleet at this time or not.

Showcase in Atlanta may rent their nanoFlashes.

TV Specialists in Salt Lake City may have nanoFlashes. I do not know if they are in their rental fleet at this time or not.

David Rogers in Nashville, drpro@sonusclarus.com, 615-866-5745 rents Flash XDR's.

(I hope I have not left any rental company with nanoFlashes out of this list!
If I have, please let me know.)

Hi Ron. I'm up in Orange County. I'd be glad to bring my XDR down to SD, connect it up to your camera and let you run it through it's paces, no charge. That sure beats a rental!

Dan Keaton · August 25th, 2009, 11:26 AM

Dear Ron,

The nanoFlash does not record x.v.color, I checked.

Hey, Dan:

Shouldn't it record whatever comes off the camera head?

But if not, is x.v. recording a possible future firmware upgrade?

John

If, for example, x.v. color required a full 4:4:4 and 10 or 12 bits to fully represent the data, there is an explanation why the CD box can not capture it.

My Sony Z7 HDV camcorder records x.v. color. (Or claims to, anyway.) So why can't the Nanoflash?

Dan Keaton · August 30th, 2009, 04:04 AM

Dear John,

I may have been incorrect about x.v.Color.

x.v.Color is not the same as Deep Color.

Here is a very interesting article about the Sony PS3. It includes a section about x.v.Color and Deep Color. I can not confirm the accuracy of the article.

This gets fairly deep. I recommend reading starting at the following section, it is a long way down.

PS3 Color Space (sRGB to x.v.Color)

PlayStation 3 Secrets

Dan Keaton · August 31st, 2009, 08:57 PM

Dear Friends,

We do support x.v.Color.

Hi Dan,

So do you mean that the nanoflash & XDR do record in this xv color mode automatically?
Thanks

Dan Keaton · September 1st, 2009, 01:20 AM

Dear David,

Yes, I am sorry that I was not clear.

RGB Pixel Color numerical values of 16 to 235 have been standard legal values for years.

Values below 16 and above 235 have been "out of range" and illegal for years.

As I understand it, x.v.Color allows values below 16 and above 235.

Many would interpret this to be 0 to 255. But since values of 0 and 255 are reserved for other purposes, I feel that it actualy means that 1 to 254 are valid. I have not found this information anywhere.

We now support, in our current releases for both the Flash XDR and the nanoFlash values of 1 to 254. 0 and 255 are still reserved as these have been assigned special meanings (not by us, but by other standards committees).

We made this change some time ago in order to support the Cumina camera which was giving us these values.

Many cameras output above 235 including Sony's XDCAM EX when using Cinegammas and the HDCAM and XDCAM HD cameras if the clipper is off or set above 100%
