Will I be able to record true 16:9 SD images ? Will I also be able record 4:3 SD images if I wanted to as well with this camera ? :laugh:
Widescreen SD ?

Yes, to both questions. And you'll have two different recording formats for SD (both DV and DVCPRO50), all in 24P, 30P, or 60i, in either 16:9 or 4:3.

So many options !!!!!!!
Barry, will DVCPRO50 look noticably better to the naked eye when compared to DV ?
Also, what was the first camera you ever owned ?

That remains to be seen, but it should look noticeably better, especially on DVD as compared to how DV would look on DVD.microsupercosym said:

If you shoot 1080P and crop in post you get as much resolution as they they had when they shoot SW E2 and E3.
So what i do hope is they put cropping bars on the HVX as they have with the XLH1.

1080P may be a waste
1080P may be a waste
Yes, it does.
I think another question that's gone unasked is, will it shoot SD at 100 megabits per second? If not, why not? If you're shooting for SD only and you want maximum quality, it would be silly not to use the full data rate supported by the camera.
Also, for those talking about shooting 1080P, it remains to be seen whether that will make any sense on this camera. If the chip resolution is only 960x720 (as seems likely), it makes little sense to blow the picture up. In fact, this could very well reduce the picture quality, because you're bloating the data payload that still has to be carried in a compressed 100-megabit stream. Better to use that data capacity to encode fewer pixels at a lower compression ratio, and then resample the image upward on your computer in an uncompressed domain if you want.

The reason why you dont shoot 100mbs SD is 2
1 The codec don´t support 100 mbs DVCPRO SD.
2. 1 GB/ min is a lot of storage. And if your final output is DVD (the standard SD delivering format) You still gonna downconvert to 4:2:0.
As for 1080P.
We dont know what the chip res is gonna be. But there isnt native 1920*1080 and it doesnt has to be that. In the DVCPROHD codec the res is gonna be 1280*1080 (pixel aspect ratio 1:1,5) with chroma res 640*1080. So even if you have higher res CCDs its not gonna help. With pixelshift they can acomplish full DVCPROHD res.
But you will on the other hand need a 1920*1080 projector/TV to be able to show the DVCPROHD material. Because of the pixelratio 1:1

Resolution isn't typically determined by the codec.

It's weird that people have this conception. That's not correct. I just rendered a 720x486 DVCPro HD QuickTime file out of Shake, and it plays back fine.
Then I rendered a full 1920x1080 clip. Also fine.
Again, the codec alone doesn't tell us what resolution they're going to encode. We're told that the camera will offer a 1080P mode but with frames split into two "fields", which means that half of each frame is going to be carried in the data stream. We know that the camera only supports three codec flavors, DV25, DV50, and DV100. So right there we have at least two different resolutions in DV100: (something)x720 and (something)x(1080/something).
Huh, I really wonder what this 1080P data is going to look like, and how it can be recombined into single frames without recompressing.

You can render out using a codec, but that doesn't necessarily mean it supports it natively. By rendering out a SD file with the DVCProHD codec and keeping it with SD res, you haven't really done anything but create a larger file size (your footage has gone through whatever compression it has already and trying to "bump" it up using the DVCProHD codec will only "bump" up from what information is there. So your footage is only really as good as its original codec.

It'll be handled exactly the same way as the DVX.stokestack said:
1080/30p will be all single frames with no need to be recombined to anything.
1080/24p with 2:3:3:2 pulldown won't need to be recombined either: it'll be four full progressive frames, followed by one disposable "split frame". Editing programs will just ignore or throw away the split frame, and work on the remaining four frames from each five-frame group.
1080/24p with 2:3 pulldown would need to be uncompressed and have the fields recombined.
