NEW Apple HDV 1.4 codec

[Jeff Carpenter]

I don’t know anything about this in particular, but a lot of alternate format specs are designed and then no cameras or VTRs are ever made to record in that variation of the format.

I suspect this is something that was invented at some point but no one ever put it in a camera. I guess someone, somewhere might find it useful in Final Cut, or perhaps they’re just being safe on the theory that someone MIGHT put that into some equipment some day.

[Wes Koetje] “Does anyone have knowledge on this? I’m just a little confused on how this works, I was under the impression that HDV is 4:2:0…. Any explanation would be great”

It’s probably just like ProRes. ProRes is a 4:2:2 codec that you can capture to or convert to from any format, including HDV.

So “presto” your 4:2:0 HDV codec is now “ProRes 4:2:2”

It’s just a codec conversion thing.

So I’m glad to know that I’m not the only one reading release notes on a Friday night.

This one line in the notes has me really curious since I work with HDV all the time. Does this mean graphics rendered in HDV sequences will suddenly be “better”? Does it also mean that you’ll now be losing visual information by outputting an HDV sequence to tape?

Walter is probably right that this just involves some on-the-fly format conversion or something. But right now I just don’t “get” what this means, if anything, or any impact this may have on now-standard HDV workflows. Does this replace the render HDV to ProRes option?

I see it as a prerelease announcement of some new camera that will have 4:2:2 HDV…?

[Devin Crane]

Is it not Sony’s new Mpeg422? 50mb/s 4:2:2 Codec. They are showcasing there new higher end XDCAM camera and Deck at NAB this year that supports this codec.

[Andy Mees]

Yes. Sony’s new PDW-F700 shoots to MPEG HD 4.2.2 – a 50 Mb/s VBR variant of the original 25 Mb/s CBR HDV standard. Without hard facts to the contrary this would seem to be no more than that.

[Zak Mussig] “Does this mean graphics rendered in HDV sequences will suddenly be “better”?”

Doubt it, you’re still working in a lousy long GOP heavily compressed format.

[Zak Mussig] “But right now I just don’t “get” what this means, if anything, or any impact this may have on now-standard HDV workflows. Does this replace the render HDV to ProRes option?”

This is most likely some sort of NAB pre-release statement. You should have more information tomorrow night and definitely first thing Monday morning.

Ah the long GOP myth being trotted out for a bit of a run again! been using long GOP with XDcam HD for a while now with Zero problems, I’m looking forward to using the new 422 50mb flavour as well.

And yes you could use this codec to replace ProRes as your HDV render codec.

That’s interesting… simplest explanation is usually the right one. I hadn’t heard about a new variant of HDV. I’ll check out that new camera, but depending on the price, I don’t know that I get the point or understand why this has a place in the product line. It would seem strange to potentially lessen the value of the EX1 as a sort of high-end HDV camera so soon after the launch.

[Andy Mees]

the EX1 and the F700 are very different cameras … the EX1 is at the low end in their XDCAM HD product range, the F700 is at high end.
now, if you’re on the lookout for something to trump all the EX1 early adopters then maybe you want to pick up an EX3?
