[Jim Krause] “I’m going to try to keep it updated as best I can. If you have any corrections or comments on how to make it more useful please let me know. (I’m already working on a better presentation)”
some corrections
the DVCPROHD spec for 1080 capture is 1280×1080 @ 4:2:2 8bit
D-5 is not 100Mbps I believe it is 220Mbps
HDCAM SR is MP4 compression not DCT.

[jbrad2] “When you are capturing set the preset the way you have and check the box(FCP5) that says, ‘Remove advanced pulldown”. Everything should come out just fine. Remember that digital will always record at either 29.97 or 59.94 no matter what frame rate you assigned.”
What???
No– there is not advanced pulldown cadence in any way, shape or form with progressive material.
the advanced cadence (2:3:3:2) is used to alleviate the “mushy” C-Frame issue when reverse telecine is done using the standard 3:2 pulldown. It does not exist with “true” progressive capture720p content is always 60 frames on tape- it cannot be 29.97
It always has to be 59.94 – that is the SMPTE spec (for North America).Gary Adcock

[David Berez] “Can I use the HVX200 to record DVC PRO HD via firewire out to a DVC PRO HD deck? The 8 gig cards aren’t long enough to capture what were looking for.”

I will be covering a couple of the alternate workflows as part of this session.
To be clear — you will not be able to bring your 1200A with you to the session, but I have a couple of answers to this issue.Gary Adcock

[tony salgado] “One last note did you check the hours meters before and after the vtr left to verify the client did not use the deck non stop and possibly captured via firewire only to return it complaining that it would not work for their needs in effect getting a free rental. Such a tactic is typical of the “hollywood shuffle”.”
Excellent point Tony….
one reason I do not rent my gear.

[Gunleik Groven] “One thing that sold me on the BM solution was that they announce a PCI-X to PCIe adaptor, which would make the card survive an upgrade of my system at a later stage.”
In reality that is never a good idea, buy the best you can afford and run it into the ground. by the time you need to upgrade a new machine – that $2000. (US) Capture board will have new features and you will want to upgrade again.
[Gunleik Groven] “Does AJA have a similar solution which also covers monitoring through DVI?
It seems that AJA boxes support up- and downconversion in hardware. Is this true?
What about sound? I’ll need to mix surround from Cubase/Nuendo.”Yes AJA’s product is called the HDP and offers scaling of the video that the BMD does not.
All aja boards do conversion in Hardware only – that is correct alsoSound is supported for both of those apps on all Kona products.

[Sean ONeil] “he needed to return it {1200a} and was getting a deck that has SDI because the client wants to edit in uncompressed. I explained that they could use Media Manager to convert it to uncompressed, and the end result would be identical quality.”
not in my experience,
Apple’s software conversion of DVCPROHD material is not what it could be and this may actually cause your client some issues for delivery, depending on the material and delivery method.Consider too, some of the conversion functions of the 1200a deck are not active except when both the HDSDI and FW boards are installed. Maybe they needed something that you did not have in your config.

[Sean ONeil] “Advanced 3:2:2:3 Pulldown is something different and is only for certain NTSC DV formats. Don’t ever use it unless you know it is advanced pulldown. Regular 3:2 pulldown must be removed using other methods.”
Please Note that the HVX200 camera can record 1080 content using the Advanced algorithms, this is the ONLY high def content I know of that is captured with advanced pulldown. [Sean ONeil]
“Regardless, there isn’t ANY type of 3:2 on your footage. It’s just 24p recorded with redundant frames making it 60p”
all 720p video runs at 60 frames on the tape, panasonic uses the standard 3:2 pulldown on all 24 frame content — thats why FCP can remove the additional frames when capturing – however the cadence or timing of the additional “duplicate” frames varies dramatically when the content is shot frame rates other than 24. Hence the reason for a frame rate converter.

[tangier Clarke] “Folks, I am using the DVCPRO HD 720p24 preset to capture taht type of footage via firewire from an HD1200A deck. When my capture is done, none longer than 25 minutes, the clip turns up at 59.94 frame rate.”
you are sure that the footage is all 23.98?
/ no color bars / no speed changes / you’re using the easy set up for 720p24?[tangier Clarke] “is there a way to remove the pull down after capture, because the REMOVE ADVANCED PULLDOWN format on the tape doesn’t allow that because it seems it works only for NTSC video.”
you need to go to the panasonic web site to get the Frame Rate Converter {FRC}
https://catalog2.panasonic.com/webapp/wcs/stores/servlet/ModelDetail?displayTab=R&storeId=11201&catalogId=13051&itemId=70438&catGroupId=15767&modelNo=AJ-HD1200A&surfModel=AJ-HD1200Athe link for the frame rate converters is listed at the bottom right of the page.
I was told that Panasonic does not support the advanced cadence for true progressive capture.
However , the 24pA format is supported in HD when using content recorded as 1080 / 24pA from the HVX200 camera.Gary Adcock

[gingerbreed] “1. If I bought the HVX200, but didnt buy any p2 cards, would I be able to capture DVCPRO compressed 720p24 footage direct-to-FCP?”
yes, but that is the slowest way to acquire footage from the camera
[gingerbreed] “1. If I bought the HVX200, but didnt buy any p2 cards, would I be able to capture DVCPRO compressed 720p24 footage direct-to-FCP?”
the “Capture Now” in FCP will accomplish that but the footage will be at 59.94 fps and need to be run the software FRC which will extract the flagged frames. –this will be easier when the Firestore FS100 and other units ship around march.
( this also answers the other 2 questions)

[Kevin Lang] “I use the Kona 2 because we have been in the Varicam business a long time and still have a old 130deck and I cant see spending 20 something grand for a soon to be obsolete tape deck.”
Kevin,
Know too, that by using the Kona 2 you can capture all of that offspeed content direct into your suite!
whether you want to work in DVCPROHD or in uncompressed.Gary Adcock
