Besides the different AR? No.

My cams shoot UHD so the aspect is still 16:9 so there is no problem but will/are consumer TV's 4K or UHD ???

Yes, there are exceptions, but they are very few.

That's almost the same issue as we had between HDV and HD with files that were 1440x1080 and 1920x1080!!

Not at all the same issue. HDV was 1440x1080 put with pixels having a different non-square shape. This helped preserve bandwidth in the 25Mbps MPEG-2 8ibt 4:2:0 encoder (which is about half as efficient as MPEG-4 / H.264). It was still 1920x1080 when you brought it into your NLE, provided it picked the correct pixel AR.

The last thing we need in a new format is having to ask the question do you want UHD 4K or full 4K ???

You won't have to ask that question. No one will ask for DCI 4K because it will be letterboxed on their display. No one is asking for Cinemascope from 1080 generated material are they? Or DCI 2K?

I wouldn't call it "more cinematic". DCI 4K is the resolution container that movies delivered digital through a DCP use, regardless of their aspect ratio. It has nothing to do with being "cinematic"...that's more in line with lighting, art direction, and the work of your colorist.

The difference is not as great as 1440 by 1080 which is the 4:3 version of HD. Oddly I can get a 4:3 ratio on my GH4 by selecting the 4K photo option, but the average punter won't really care.
|
They would care if you gave them a 4:3 video to play on their 16:9 LCD TV because it won't take up their whole screen and be pillarboxed on the sides. What the 4:3 mode on the GH4 is for is shooting with PL anamorphic lenses, which will give you 2.40:1 aspect ratio when you correct for the AR.

Whether UHD or 4K, it'll still be seen and described as 4K by most. Especially as most resolution formats are defined by vertical rather than horizontal resolution.

Exactly. |
