If this is correct I think it is a major loss.

If 1080p/720p is to be a low-cost, lower work flow option, it would be good if it could be shoot in 4:4:4 single drive with the red codec. I think, if you can't afford 4K drive arrays, it would make better Cinema/Blueray options for footage.

There is some strange 2K windowed and scaled modes that can do 4:4:4, what are they about?

I think it's a bit early to start nitpicking specs at this level.

Besides, if you look at this page:
http://www.red.com/products/cameras/redone/specs.html, it says 1080p 4:4:4 and 4:2:2.

The oversampled 2K at 4:4:4 Redcode video sounds pretty good to me, wonder what the datarate for this would be like at 24 fps. Have to do some digging. Or what about just cropping or scaling the 4:4:4 2K video to 1920x1080 in post? Which would be kind of nice because you could actually shift the frame if needed.

Steve Gibby's article gives some info on those mode. Per 1080p, I think it's a no brainer to shoot 2K 4:4:4 for that and crop/scale as needed. Just like the RED's 4K oversize 35mm frame. You've got some extra stuff to use to adjust.

I managed to post a reply to this subject in the wrong thread:

Interesting, this is also strange:

If you look at this page, it lists the "video output" as 4:4:4 at 1080p, but note that the Red codec only goes upto 2K which is the only one listed at 4:4:4

http://www.red.com/products/cameras/redone/specs.html

I read, I think at hdforindies, that 2K has low horizontal resolution but great vertical (maybe 3:2 format I didn't look at it). So, upscaling to 1920 is not the option I would like. But as you can record HDSDI (video output) I supposed that it doesn't matter. I just hope the Red codec is not restricted to 4:2:2 1080p, or to 2K. One should definitely be doable at 100Mb/s wavelet, the other should have room for higher resolutions, especially if 200Mb/s thing pans out. But some drives can do 50MByte/s sustained these days, so I hope they do 400Mb/s.


Now look at this page, this was the one I was looking at:

http://www.red.com/products/cameras/redone/formatoptions.html

Notice that the higher resolutions are "Raw" and the ones 2K/1080/720 are given formats (4:2:2 for 1080/720). I wonder if the Raw modes have compression options?

Maybe the wrong data is on the pages.

I think 2K isnt what you think it is Wayne.

2K is 2048x1080.

1080p is 1920x1080.

So if you want 1080p 4:4:4 recording in 2K and then discarding such a tiny amount of data is trivial as Stephen has said.

2k full aperture is 2048 x 1556.

Ok. Thanks, good news. Wrong, twice in a day ;) Been sick, I checked at hdforindies and can't even find it.

If the moderators would like to delete this thread, it would be most appreciated.


Thanks

Whoops, yes it varies with the aspect ratio (slaps forehead). Many more scan lines for full apature 'Acadamy' or certain anamorphic formats, but for a super 35 sensor like in the RED somewhere around 1150 lines 'probably'.

If you do the math (i'm too lazy) you could figure it out here:

http://www.red.com/products/cameras/redone/formatoptions.html

I think I'm in the right ballpark and coming up with the exact answer will be more tricky than knowing the sensor area, the formats tend to be designed so that they are a multiple of 8 high and wide (so they fit neetly into compression methods like 8x8 DCT) with the exact aspect ratio encoded being the thing thats aproximated.

I'll hang back and wait till we hear from RED on the basis I don't want to make any more avoidable mistakes today :)
