  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

ProRes422, no 1080p???

ProRes 720p is 1280x720, square pixels. 1080i is basically always broadcast 1440x1080, non-square pixels.

Interesting,

I did not know that, and it explains why they would make HDV 1440.

It still seems like a scam on the consumers, but whatever. I just need to be able to deliver something that looks as good as the rest of the stuff they are watching.

Is there anything out there that is actually 1920 x 1080? TV sets, signals, Blu-Ray, HD-DVD???
 
It shouldn't be broadcast as 1440, but for long enough, even though the HD format was 1920x1080, some people in their infinite wisdom thought that 1440x1080 was good enough. Others thought 1280x1080 was good enough. SO there was no point in broadcasting HD at greater resolution. Daft really as anything decently telecined from 35mm film would be the full 1920x1080 (if they had a deck that supported that rate to telecine to, which for long enough, they didn't).

So let me see if I can get this straight,

HDTV is broadcast at 1920 x 1080, but they usually only provide 1440 x 1080 content?

*EDIT*Radio reference removed so as not to insult the overly sensitive:)
 
Nope, it's usually broadcast as 1440x1080.
 
That's too bad.

Do you know if that is true of all broadcast? And what about HD-DVD and Blu-Ray?

Is there a reason I should care about full raster if it will never see the light of day???

By the way, I plan to use this camera for at least 5 and hopefully more like 10 years...

Thanks,

Tim
 
No, Apple are wise and ProRes is full raster, ie 1920x1080.

Sony's HDCAM is 1440x1080, Panasonic's DVCproHD is 1280x1080 (or 1440x1080 in PAL) and 960x720 in 720p. None of which are full raster.

Ok, so just for the sake of argument, what benefit is there by going with full raster 1920 x 1080 if the only thing that consumers will ever see is 1440 x 1080? Going below it makes no sense of course, and obviously higher rez means good down-rezzing when you are talking about 4k scaled down to 2k or HD, but what about 1920 down-rezzed to 1440? Any benefits???

Thanks,

Tim
 
All (or close to all) Blu-ray and HD DVD's are full raster 1920x1080p23.97 4:2:0 8 bit.
 
Thanks for the info Anders...

What is HD

What is HD

At least CBS insists that all their prime time material is broadcast as 1920 x 1080, hence they will only accept material delivered on D-5 HD or HDCAM SR. i.e DVCPRO HD and HDCAM are not acceptable.

Of course once their 22Mbps MPEG-2 1920 x 1080 HD signal hits your local cable company all bets are off.... but I guess the point is CBS are more likely to be buying or commissioning your content than the cable company.
 
Yes, 480x1080 chroma. Yummy. Don't you just love it. Not that they were upfront and told people about HDCAM's little "secret" though. Nice of them.

Are you sure about that ? Aren't mpeg-2 HD specs 1440x1080 ?

I don't know about H.264 or VC1, are they 1920x1080 ?
