John,

As a follow-up of our previous discussion on using Samsung SUHD for monitoring your editing and viewing final production: you're now saying you can play back your 4k movies with no higher than 60 mbps bitrate - how about chroma subsampling and number of bits per color? Do you render out keeping the 10 bit, 4:2:2 format, and does it still play back well (and in all its glory) from a PC, hard drive and /or flash drive? Thanks,

Piotr

Hello John.
Thanks for your reply. I also read the additional comments, which make me realize that I am still a beginner. All I know is that I rendered in Vegas PRo 12
using XAVC S 4K 3840x2160 Long -GOP-25p format.

My ( slow) Dell Inspiron PC plays this movie using the VCL media player.
I can actually export this movie back to my RX10 and RX100 they can't play it.
The TV is a Samsung UE48JU6000 As I live in France, it is all in PAL of course.
The strangest this is that if I render the movie in 29.97p, my RX10 plays the movie albeit shockingly It also shows in 4k on the TV. but it is not a good experience. . . .

This makes me think that there should be some way to make the camcorder read edited 4k movies and play them back on a UHD TV
Sticking the SD Card with the movie in the card slot of the TV does not work unfortunately.

I guess I may need to be more patient and wait until 4k home movies become a more interesting business for Sony

Just a little addition. April 25/2016
My never ending efforts to try and show my 4K home movies on my UHD TV have resulted in an experiment whereby I loaded 2. 4 k movies of 10 minutes on my Xperia Z tablet phone and to my great surprise I could play the movies without a problem.
Next I used an adapter and connected it to the TV with HDMI and it worked . . . . . for.5 minutes then is crashed on lack of RAM probably.
If I don't connect it to the TV it plays the whole movie without problems. I wish I understood this???

looking forward for PS4 4K edition...

Piotr- 95% of the time, I play 4K content on my Samsung via the DisplayPort on my computer, the video card is an nVidia Quadro K2200 and the TV is capable of displaying 12-bit 60fps YCbCr 4:2:2.While the TV is limited to playing MP4 files at 3840x2160-30p, it will play UHD HEVC (H.265 - Main, Main10, Main4:2:2 10) at 60fps at up to 80mbps.

When playing through the computer, there is no practical limit on the bitrate of the files and they look spectacular.

Thanks John; I'm also going to play my files from PC mainly - but out of curiosity, how do you render to UHD HEVC (H.265)? Is there such a template in Vegas Pro 13?

Piotr

Cyberlink Power Director will let you render your project to H265. You can play back h265 on your 4K TV

Handbrake will also render h.265.

Interestingly, even Mercalli 4 SAL can render in this format.... Unfortunately, VP 13 cannot read it! Not even Catalyst Browse can - what's up, SCS?!!

Piotr

PS. Unfortunately, Prodad downgrades to 8 bit 420....

h.265 is relatively new and not that widely used yet, it requires quite a bit of computational horsepower. As far as Vegas not supporting it, I'm sure there are licensing issues and financial considerations.

First of all, my apologies to the OP of this thread for stealing it :), but just one more question to John:

John - as you know, I'm about the purchase the Quantum Dot Samsung SUHD TV. I was already close to pull the trigger on a 2015 model (UE455JS9000), when I learnt the 2016 model line-up is soon to hit the shelves (instead of "JS", the have "KS" in their names; K like Quantum of course - so basically SUHD is becoming KUHD). From what you explained to me in another thread, basically there is no difference, but now I see there is one: the 2015 models were NOT rated as HDR (for High Dynamic Range), while the 2016 ones are (like e.g. HDR1000 for the 9500 series). Please tell me: do you think it's another marketing trick to kick-starts the newest models (obviously more expensive than the 2015 ones), or is there something important to it? I have doubts, because I just cannot imagine even the 2015 models were not HDR - this is one of the basic high-end characteristics! So, is 2016 even High(er) Dynamic Range, and thus worth to wait and pay more? Thanks, John!

Piotr

h.265 is new technology. Whether it is to become the Kitty Hawk flyer of the 2020's is about a 50/50 shot right now.
It is still terribly slow to encode and terribly hard on CPU/GPU playback capabilities. It is historically accurate that those hardware considerations will determine the eventual outcome and winner of the codec wars, if again only temporarily.

The bell sounds for round three of the long-GOP encoder battle; without naming the competition, h.265/x265 faces an uphill battle.

Note to the uninitiated: h.265 technology presents a compression/bandwidth advantage, generously 15% or so over h.264, and nothing else at this time. The monstrous increases in encoding times and playback system load are curiously the two things that never get mentioned. The "quality" line is only hype to cover up the actual losses from more and more extrapolated compression schemes during encoding. The only legitimate recipients of that real bandwidth advantage are streaming broadcasters, who stand to save billions in infrastructure costs as the thrust towards UHDTV for the masses advances. When is enough "good enough?".

To home and prosumer users, however, the advantages of h.265 are trivial, owing to cheap hard disks and cloud storage, taken against the expense of system hardware upgrades needed to reliably play back the newer formats, especially at 4K and higher resolutions.

When are we going to stop obsessing on the hype, and realize as otherwise conscientious professionals, that higher quality and lower bandwidth come with a price tag?

That price tag always seems to turn out to be time. What's that worth to you guys?

The Samsung 2015 JS series TVs do indeed do HDR. The new KS series is an incremental improvement with some new operational features relating to their "Smart Hub".

One more question if you will, John: are you using a DisplayPort to HDMI converter, and could you refer me to the one you're using? TIA

Piotr

John, could you please advise on a good DisplaPort _> HDMI 2.0 adapter/cable that you're using? Thanks, mae :)

Piotr

Naïve me thought I would be able to burn a 4K video to Blu-ray on my Blu-Ray burner and play it on my 4K UHD Blu-ray player and watch it on my 4K UHD television, only to discover on my first attempt that there is no option to burn a playable 4K UHD Blu-ray disc in any Magix Vegas version (if I have read this forum correctly).

Yet, posters here dangle the tantalizing prospect that it can be done with some workarounds.

Can someone offer a step-by-step method for getting a 4K UHD video to be watchable on a 4K UHD television?

You are right - no option to make a UHD Bluray with any software available to consumers. Big business only for now.

Couple of options: (1) render a UHD h264 or h265 ( HEVC) file and put on a thumb drive; stick that in your TV.

or (2) use a networked device that runs a media server. I use a QNAP NAS with server software that my TV can "see" so it can play back whatever files are on the NAS.

Disappointing to be sure.

I will try the first option.  I have rendered a UHD file for uploading to Vimeo.  Not sure which Codec I used but shouldn't be difficult to figure out.

 

The second option is also intriguing.  I have a Synology server but I have barely scratched the surface on its functionality.  Both my TV and the server are networked so I will give that a try too.  Thanks.
