I’m not sure whether it’s my TV that needs some very specific settings in order to view the 4K content, and as such PSP doesn't support that "flavour" of 4K, or it's something else. I think compatibility may be better if PSP7 could output H.265 (HEVC) but that's only an assumption, and I don't know if Photodex have any plans to include H.265 into PSP7.
Also, I've noticed with PSP7, the render times for 4K are abysmal. A 30s video takes around 6 minutes to render (Intel 4930K CPU, 6 core (+6 virtual cores) overclocked to 4.2GHz and 64GB memory.
Has anyone found a solution to Samsung TV playback.
mikey (PSP6, Photoshop CS6, Vegas Pro 14, Acid 7, BluffTitler, Nikon D300s, D810)
Lots of PIC and Arduino microprocessor stuff too !!
The Supported Codecs for my Samsung TV are as follows:
4096 x 2160 (maximum 30fps) & 3840 x 2160 (maximum 30fps):
4096 x 2160 (maximum 30fps) & 3840 x 2160 (maximum 60fps):
Exporting video as HD 1920 x 1080 from PSP7 causes no issues at all with TV playback.
As I subscribe to Adobe Creative Cloud, I successfully re-rendered the video from PSP7 to a H.265 codec using Adobe Media Encoder, and it played back on my TV just fine. Downside is of course re-encoding the video twice over, plus the additional rendering time on top of that, so I'd rather get it right straight out of PSP7 if I can.
Having PSP7 use H.265 would really be beneficial, so I hope that's in development.
I've also opened a support call with Photodex, regarding 4K output but haven't received a reply as yet. I'll post the response when I receive it.
For those who want to give it a go, and have a 4K TV (this works on a Samsung), try the settings below. Photodex support also said they'd be looking into supplying 4K pre-defined presets going forward. No news on whether they'll support H.265 however.
Compression: MPEG4 AVC
Resolution: 3840 x 2160
Aspect Ratio: 16 x 9
Framerate: 30 fps
Quality>Average Bitrate: 35000 kbps
Video Profile: High
Audio Format: AAC
Bitrate 256 kbps
Sampling Rate: 44100 hz
When I built the file using "Custom Video File" I did not see anywhere to set the Audio parameters other than bitrate. Where did you adjust these audio settings?
I very much appreciate your perseverance!

How close is "very close"? If you have to be very close to notice the difference, is it worth upgrading?
As for viewing 4K, I'd agree, there's not a lot of difference overall, and it's not discernible for every slide. What is noticeable is some images, depending on the slide style chosen is they tend to take on an almost 3D like appearance, and really look like they're floating in space. Content plays quite a large part here, with high contrast images really looking that much more detailed and sharper, but I guess that's more a human perception thing than science.
I'd say 4K is better, but not so show stopping that you would wish to exclude anything else. I'm happy to stick with full HD, and just keep my slides shows archived for potentially re-creating in 4K if there really was a burning desire. It was an interesting experiment to create a native 4K video, but having done that, seeing the results, and of course how much longer a slide show video takes to render, HD is still the preferred choice - unless of course you're premiering your slide show on a 90" TV or something!
Joe, I had to have my face within 3 ft of my 60 in. 4K screen to really see the difference. I agree with Steve's comments above. The differences I noticed (at 3 ft) were the lack of any "jaggies" on large text titles, and a less "flat" look on images. The upscaled 1080p/HQ images had a slight oversharpened look to them compared to the much more natural look at 4K. Fine details were better resolved. At my normal viewing distance of ~9 ft. any difference I saw might be wishful thinking - i.e. perhaps a slightly less harsh look due to the oversharpening-like edges of the upscaled 1080p/HQ. Based on what I saw, I wouldn't run out to buy a 4K TV just yet to view slide shows. Just for completeness, building the 4K test show I built with Steve's parameters vs the identical show in 1080p/HQ was:
Length of slide show: 1'42" 1'42"
Number of slides: 14 14 (10 image slides, 3 title slides, one blank slide)
Time to build the show: 13'13" 2'50" (Using PSPv7 "Video for Web, Devices, and Computers")
File format: .mp4 .mp4
File size: 391MB 70MB
(My preview shows the comparison in my reply rather disheveled even though it was typed in, but if it ends up that way after posting I think you can still figure it out. Sorry in advance.)
Essentially, 4K is fantastic, amazing, stupendous, (insert superlative), for movie theaters and other very large formats, but the advantage is not so great for your average home TV viewer.
And I suppose that also will be true when the 8K and 16K TV's come out in the next 4-5 years. Surely, the human eye has a limit to what it can perceive and our pocket books have a limit too.
4K videos straight out of the Sony camcorder (via HDMI) played back fine on the Samsung TV, picture quality was great.
My ProShow Producer generated file didn't play back on the Samsung TV (via USB connection using a USB hard drive), got the message "Frame rate not supported". I played the same file back without any problem using the WD HD Multi Media Drive hooked up to the same TV. I bought this drive as a did run into file compatibility issues in the past, trying to play back videos directly into the TV via USB. The WD Media drive works perfect for me, no more compatibility issues with any TV (old or new) and the video quality on the screen is great. So I continue producing shows with PS Producer as usual, even when 4K or XAVC S HD videos clips are included.
