Thanks again. We’ll see how it goes. CIAO!!!

I tend to enjoy my consciousness more when I choose to keep the veil over my psyche. – Jerry Miles
Hi Jandro,
There are so many things to consider I hope the following helps your understanding.
Some definitions first:
DVCPRO HD over firewire = compressed format (contains digital algorithm that presents itself as a blocky artifact if messed with to much in post production) Walter witnessed this phenomenon and chose to go uncompressed for final color corrections.
DVCPRO HD over HD-SDI = the deck has removed (decompressed that algorithm) and is sending out raw data that can be placed into an uncompressed file format which can be either 8 bit = 256 levels of stepping or 10 bit = 1024 levels of stepping. Choosing between these levels depends on content and how much space in hard drives you can afford. It could also depend on how much the client is willing to pay you for those additional in the future projects you wrote about.
The firewire acquired footage involves that digital grid that for most basic editing purposes will be fine. Of course this to will depend on content and the discerning technical eye.
Editing = cuts, dissolves and basic transitions. I know it involves far more so please don’t bust my ….s. =)
Compositing = placing images and/or parts of images over other images that may or may not be of the same resolution and attempt to make them seamless or as one.
Color Correction = functional correction for wrong white balance or could = forcing the color that was acquired to a different value to invoke a style or feel. It could also help the story move you to a place where you might feel safe to unveil your psyche. =) don’t laugh. I dare you…
STORAGE needs:
DVCPRO HD = 5.6MB/sec to 14MB/sec depending on resolution and frame rate. Hour of compressed at highest data rate = 50GB give or take for lack of scientific calculator at my deck.
Uncompressed file format:
8 bit = 120MB/sec give or take a few MB for additional audio tracks. 432GB for an hour.
10 bit = 160MB/sec give or take a few MB for additional audio tracks. 576GB for an hour.So…
If your passionate about your project and you have spent countless and endless hours of time setting up your shots and waiting for that perfect moment in time to capture that special glow of light. Or maybe you have mastered the ability to create your own reality with blue and green screen shooting and will composite later you probably don’t want to finish in a compressed format. You will want and desire the ability to at some point in your workflow pull all your selects into the computer in their uncompressed glory for final manipulation and output. If this is your goal ProMax will help you achieve it.
We offer many storage solutions from Fibre Channel to our SATAMAX line of storage products. Please keep in mind these additional storage notes that need clarification: RAID 0 products are less expensive and provide incredible performance but should be used with Timecode and proper workflow guidelines. RAID 3 and RAID 5 solutions are more expensive but provide an additional level of protection from a single hard-drive failure. NONE of these products protects you from a crash that causes the Operating System to scramble the directory structure of your drives. RAID 3 and RAID 5 are NOT backup solutions!! PLEASE remember to always make backup copies of all your project files and other important data that can’t be easily re-digitized via time-code.
As you can see Jandro this is pretty involved and it appears we probably need to talk on the phone and get to the bottom of your specific needs which is how ProMax Systems, Inc. came to be so successful over the years. We cater to your custom needs and want you to be successful.
Thanks for reading and I will contact you tomorrow or feel free to call me at your leisure.

Have you tried dropping native DVCProHD into an 8 bit uncompressed timeline and rendering? I would guess it would acccomplish the same thing?
Our film takes has a lot of scenes in one room with red / pink hued walls. The DVCPro HD codec is not very happy with that color when I start color correcting, it gets very blocky and some vertical banding starts showing up. By coming in at 8bit uncompressed, the blockiness and banding goes away.

Nope, it doesn’t work. When the footage comes in via DVCPro HD, you can see the beginnings of the blockiness and vertical banding. Apply any filter to this footage and it’s greatly enhanced.
It’s not visible playing straight off the deck via Component to a monitor, it’s only when it’s captured into the system via DVCPro HD either by Firewire or HD-SDI.
Capturing 8bit Uncompressed eliminates the issue.

No— it does not
it actually screws with the image due to the different aspect ratio of the 2 file types.
UC 8bit is the full 1280×720 where as DVCproHD is 960×720Gary Adcock

See, that’s why I recommend ProMax so much, they take the time to explain things and listen to your specific needs.

I wonder if you would still see the problem. What it sounds like to me is that when the image gets scaled to the correct aspect ratio in FCP the chroma is not getting scaled well. But if you are outputing with a Kona the Kona would handle the scaling coming from the video outputs(if you are using a DVCProHD timeline). You would still see the bad FCP scaling if you put DVCProHD into an uncompressed timeline like you say because then FCP is doing the scaling internaly. -
Walter, can you send me some footage that exhibits this problem, and the uncompressed version that does not, so that I can do some investigations.
