Highest Quality Resolution in hd110u
 
30p 720 I believe is the settings for the highest resolution you can attain on a HD110u. Am I correct?

I haven't slept for 3 days as I write this so feel free to chuckle amongst yourselves.

Eric Darling April 13th, 2007 11:48 PM

In both visual and temporal terms, yes.

Carlos Rodriguez April 14th, 2007 01:38 AM

wait a second, I thought the HD110 provides live 720/60P analog component output (4:2:2 equivalent), which should be higher quality? Unless you're talking about what goes on tape.

Bill Ravens April 14th, 2007 06:55 AM

Carlos...

How do you propose to capture 4:2:2 component while in the field?

Antony Michael Wilson April 14th, 2007 08:57 AM

I was thinking generator, Mac, Kona card, RAID array mounted in a rack with wheels, tethered to the HD100 and an assistant to push it all along. But if you're actually in a field you'd need bigger wheels. You could just use a cheap plug-in to filter out the generator noise and fix right up in post. Blackmagic instead of the Kona card for those on a budget...

Higher quality in chroma perhaps, but lower in final pixel detail out component.

That's what I'm doing wrong, I keep forgetting to budget one of those. ;)

Hey Daniel,

Why do you say lower final pixel detail? Because it's no longer digital?

Also, I keep forgetting that I need to get to know you. I live/work only about 2 miles away from digital media one in west knox. I know you all are getting a RED cam, and my company is also looking at getting. I actually did a little work for you guys while I still worked at HPVideo--I helped Josiah Morgan pull some footage off of the HVX-200 P2 when you first shot HD for Patricia Cornwell. Shoot me an email at matthew@macvilleproductions.com

Thanks,

Matthew

For me the best quality you can get from hd100-200 is recording in 24p and converted to 8-bit 4:2:2 for more accurate color correction and fx

Bill Ravens April 15th, 2007 05:14 AM

Glad to see that reason prevails...duh, why didn't I think of that..i.e. having a video processing facility tagging along with me....uhhh, maybe a real lo-o-o-o-ong umbilical so I can get into the bush...hehehehe. Lord knows being able to chroma-key is the difference between a backyard production and the real thing, eh?

I know that chroma keying is actually pretty good with the 110U. I just shot some food that I bluescreened and it looks like it was shot on a varicam in 4:2:2. The real key I think is making sure the detail is turned down (I know it sounds strange, but you don't get jagged edges) and converting your footage into a 4:2:2 or 4:4:4 format (I chose Sheer video.)

It would be nice if someone came out with a DTE device that had component imputs--then I could shoot 60P HD on my 110U!

Yeah, that would be a HOT seller. Unfortunately, it's a very difficult problem. The solutions are expensive, bulky, and power hungry. The most realistic approach is to capture component from the camera, convert to a compressed format before writing to disk or CF memory. Compression techniques are destructive, so, this part needs to be done carefully. Only Cineform seems, so far, to have this technique commercially available. Something like 12 bit, 4:2:2 is needed, and that means a lot more storage space than is practical, currently, from CF memory. Hard drive storage is power hungry and very fragile.

Sorry, off topic for a sec here...
How about that. Neighbors indeed! Closer than you know... Westland. A lot of production people in this town thanks to Scripps Network and HPVideo. ;) Josiah, Danny, all good people.
I didn't know we had any other HD100/110 shooters in the area besides Joey Davis and myself? You missed out on a shoot a couple weeks ago, a New York production company hired us for a 4 camera shoot (JVC cams only), most fun I have had all year.

Back on topic.
And yes, I mean the image starts to degrade (goes soft) when pushed out component and the cameras DAC compared to even HDV/Mpeg stream. It's a trade off of more color for degraded image detail. Hardly worth the trade off when keying. Capture 2 seconds uncompressed, while also going to tape as HDV, then compare the two frame by frame. If uncompressed via component works for your application, then you are very lucky.


Peace!
