XDCAM HD Settings?

[Mactrix]

It’s not possible … HDV and XDCAM HD are using the same 25 Mbit Codec
and the 35 Mbit version is only available with XDCAM HD.

Due to the MPEG-2 GOP structure you can’t capture HDV as 35 Mbit XDCAM HD.
You can only transcode it after capturing …

[Jay Chance]

I almost had it working using the analog component out of an HDV deck into a Kona LHe card…but I was dropping frames on the capture….I’ve got an email into AJA support on this issue. Here is a link to a white paper from AJA on using HDV footage.

Take a high detailed image scene and compare the analog to whatever conversion
with your native HDV import. You will cry, I promise you … the analog outputs on
HDV camcorders or decks are questionable at best …

While I fully understand that XDCAM HD is totally different from XDCAM, I did use HDV captured thru my Kona 2 into the XDCAM IMX50 codec. It works superbly.

[mactrix] “Due to the MPEG-2 GOP structure you can’t capture HDV as 35 Mbit XDCAM HD.

To answer this…. I can digitize into ANY codec except the XDCAM HD codec. At the moment, I’m haing to capture everything in the DVCPro HD codec because its the most compatible codec I can use at this time.

My problem seems to be where FCP and the Kona meet. Nowhere in FCP settings is there a scene aspect ratio of 1440×1080 except with HDV and I don’t want to work in HDV.

This is another story. Capturing thru the Kona will disengage the GOP structure. It’s no
HDV anymore, it’s a transparent signal.

“To answer this…. I can digitize into ANY codec except the XDCAM HD codec.”

Again, via the Kona 2 it’s possible to capture any codec, depending your system speed.
You can also capture DV formats via FireWire to any codec, however not native HDV.

“My problem seems to be where FCP and the Kona meet. Nowhere in FCP settings is there a scene aspect ratio of 1440×1080 except with HDV and I don’t want to work in HDV.”

If you are using the Kona card than you will input a transparent signal via HD-SDI.
It’s not recommended to use analog inputs. A Convergent Design cross-converter
can convert HDV to HD-SDI resulting thru a pure digital transfer. Also 1440 x 1080
subsampling from HDV is upscaled to 1920 x 1080 full res. You can use the Kona
than to capture to uncompressed or DVCPRO HD.

Yeah, I’m sure it has something to do with the aspect ratio conversions – converting from 1440×1080 to 1920×1080. I’m not too sure that FCP really has full support for XDCAM HD just yet. This is similar to what was going on when XDCAM came out last year in FCP.

But I’m glad to see that someone else is working on this issue.

“Yeah, I’m sure it has something to do with the aspect ratio conversions – converting from 1440×1080 to 1920×1080.”

When capturing thru the Kona card the signal is already 1920 x 1080.
This is done on the analog outputs of the HDV deck and has nothing
to do with FCP …

“I’m not too sure that FCP really has full support for XDCAM HD just yet. This is similar to what was going on when XDCAM came out last year in FCP.”

What do you mean by full XDCAM HD support? All codecs are fully
supported. But XDCAM HD is an import format, no capturing format.

I’ve already been doing this for the past year… The problem is you can’t digitize ANYTHING into XDCAM HD at any rate. I’ve even tried to render out animations from After Effects with no success of stable video.

[mactrix] “You can use the Kona

YES… I’m very well aware of that and have been doing this already. BUT I’d like to capture into XDCAM HD so that I can use the transfer software to import and export. At the current moment, I have to edit in DVCPro HD and make a new sequence of XDCAM HD and render it out for about 6 hours for a 35 minute program (bars, tone, slate, and black after the show).

It’s is and was never a feature of FCP or AJA to capture into XDCAM HD.
XDCAM HD with variable frame rate and GOP structure is no capture
codec …

“I’d like to capture into XDCAM HD”

It’s not possible.

I understand its capabilities completely… I preach on here about the misgivings of HDV all of the time.

BUT, what you are missing is the fact that I can create files in HDV in Compressor and After Effects all day long. I understand that the nature of XDCAM HD is still a form of HDV but why is it that I can create 25 mb/s HDV files but not XDCAM HD files. That is my whole quandry.

When support for XDCAM SD came out last year, I was having similar problems with it in FCP until an update came out to help with this issue.

[mactrix] “It’s not possible.”

Then explain how I can create files in After Effects and Compressor in HDV. FCP looks at HDV as something completely and totally different than anything on the market. Why is that?

Don’t get me wrong… I love FCP and will continue to use it BUT its behind on current technologies that should be working.
