Hi Aaron,

I'm sure you're right however, I have worked with both and the difference between 8 and 10 bit has been worth fretting over - particularly when it comes to process work.

Obviously other factors are important too.

So you prefer to keep working in 36Mbps 420.
160 Mbps 422 is not good enough because is just 8b.
Or 10b Uncompress or nothing.
I don't understand nothing. Suddenly everybody wants 10b Uncompress.
How many of us can afford an Uncompress workflow in HD?
If I would be able to maintain a 10b Unc workflow I would be looking for a different solution than the NANO.

S.two does 4:4:4 10bit Uncompressed. So does the Thomson Venom. I think the KG UDR-D100 does too. If you want to tether you have lots more options too.

Do you spend much time grading EX1 material in post?

As soon as you have some material that is very motion intensive (i.e. very codec stressful, and yes, you can still break XDCAM EX 35mbs fairly easily) and have to push the image a great deal because it's underexposed and desaturated, then have to render back out from your multi-generational ProRes or CineForm intermediate to mp4 at less than 19 mbs for your final Blu-ray distribution copy....welll, you may appreciate starting out with full 4:2:2 uncompressed quality acquisition.

Barlow, Thanks for the vote of confidence for the Nanoflash. I do some color balancing and exposure correction, but usually, not more than that. So far, I have little need for an intermediate format. My material is motion intensive, so that is my interest in the Nanoflash over native EX1.

Glints,
I'm not trying to sell any NANO, and no need of any vote of confidence for the NANO-Flash.
Many of us we are working with the NANO already since a couple of months ago.
Don't need to be an engineer to see the difference NAO/No-NANO.
Nothing easier than what Paul suggests:
Record whatever you want in the SxS and in the NANO and make an split-screen with both pictures.
No more tests needed, believe me.

Dear Gints,

Just the week, Paul Cronin was in a customers office and they have two high-quality, calibrated identical monitors.

He showed the native 35 Mbps 4:2:0 footage and the nanoFlash 4:2:2 footage.

The client asked, "Did you use two different cameras for this shoot?"

Side by Side, the difference is readily obvious on good equipment.


Last year, Paul, in his own editing suite, with two identical monitors had two frame grabs up. His wife walked in: "Paul, why did you color correct one image and not the other?"
His answer, "Neither was color corrected, one is 4:2:0, one is 4:2:2". (an approximate quote).

Gints Klimanis October 31st, 2009 05:28 PM

Thanks Dan and Rafael. If only the frame grabs from your experiences were available to those that do not already have a Nanoflash or XDR ...

Dear Gints,

We are working on your request.

1. Paul Cronin sent us some files on Friday. These are on our server and our plans are to work with these on Monday, so we can setup links to the files.

2. Alister Chapman sent us some files today.

We will also work with these on Monday.

Paul Cronin November 1st, 2009 09:08 AM

Dan your quotes are accurate. Hope the files work out. I am on the road shooting through next Sunday so not FTP while on the road. If you need more files let me know, happy to help.
