Yes, it takes 6X longer probably because the SVRT and the hardware acceleration is greyed out. I will discuss it in the Power Director 13 forum. I Think they will allow HEVC to become faster in future firmwares or PD14,15,16 etc..HEVC takes up half the space (compared to H.264) on the HDD which is no big deal when one has 2-3Tb HDD:s.
The Zappiti 4K player only allows HEVC 4K <37Mbps but the picture quality is outstanding. Simply gorgeous...I have a slot in my pc and the internal WD Caviar Green HDD goes into the slot of the Zappiti 4K. It upconverts my MP4 and AVCHD 2.0 1080/50p videos very nice too.
Chris, You cannot play H.264 4K files in the Zappiti 4K without stutter and judder. One must convert the files to HEVC H.265. At least that is my experience and the advice in the Zappiti Forum.

Ok thanks,my tv only plays H.264 4Kedited files direct from my externals,i said my renders take 2x which is true but not 32m for a 30m film i meant 64m.

Chris, You can download HEVC videos from the Zappiti forum via Dropbox to check if you really cannot play them.

Anders i have done a H.265 HEVC MPEG.4 4K 37Mbps render of a short 3m 51s flm and it took 34m 58s to render and the film only plays jerky start stop on my PC,it does not seem to work for me.

You could join dropbox.com. There one has 2Gb free uploads which would be enough for the HEVC file. Then I could test it in the Zappiti4K and my pc.
When you render FZ1000 videos in Power Director I would advice to use the smart rendering option(SVRT) which makes a profile of around 97Mbps with 2160/25p. Then render with hardware acceleration on. I read somewhere that you use lower bitrates (correct me if I´m wrong). It works to render in XAVC too. PD13 often render 1-4 clips badly with MP4. Does that happen to you too?
I think one has to use only original clips from folders to succeed with HEVC not the rendered videos.

Sadly smart renders of MPEG.4 3180X2160 will not play from external drives on my Samsung tv[they play on my pc] only normal 3180x2160 renders play on the tv,but they look fine the trouble being the problems playing the drives can give on the tv as i explained previously.
you are welcome to download the film from vimeo,it plays normal at 720P on my pc,not good quality focussing very difficult in the conditions.Just thought i dont know if you are able to download vimeo films or if you have to be a paid member.

Chris, I downloaded your HEVC 4K video from Vimeo and it plays fine on my UHD TV Panasonic AX800 from the Zappiti 4K player and also from my pc with WMP (Win 8.1) and MPC-HC.

So, what I found out from lurking in the Cyberlink forum is that to get faster HEVC encoding I must wait for Power Director 14 and sell my card GTX970 and by the cheaper GTX960 that will support Hardware acceleration encoding. My GTX970 does support decoding because HEVC looks stunning in my pc:s with WMP.
Eugene, I saw that you have the GTX960 and have tried HEVC. Do you get faster HEVC renderings or do you wait for PD14?

Edit: I got a reply in the Cyberlink forum. If and when Power Director 14 will support H.265 HEVC both the GTX960 and GTX970 cards will do Hardware acceleration decoding and encoding. Hence faster renderings.

Chris, I think you should use the same email and login as when you purchased the PD13. After you are logged in to Cyberlink you can choose a username for the forum.. That is how I recall it from 2011 when I joined.

If you saved the emails that you got from Cyberlink when you downloaded PD13, then you will find all the information there, I think..

This is a very interesting topic.

Here are a few observations from my end:

1.) x264 UHD 29.97fps (at twice the bitrate) looks just as good as HEVC, and plays fine on my Samsung HU8550 without a player. I just put the file onto a flash drive and plug it into the USB port on the Samsung.

2.) h.264 UHD 29.97 fps plays at up to 100mbps on my Samsung UHDTV just fine, and can FFWD and FREV.

3.) h.264 UHD 59.94 fps will not play on the Samsung. For that frame rate, it has to be encoded HEVC.

4.) The Samsung plays my UHD 60fps HEVC buttery smooth at 50 mbps but you cannot FFWD or FREV. I have not tried 100mbps but it really does not seem necessary, looks great.

5.) HEVC is painfully slow to render. I use x265.

Time to follow up on this thread. I sold the Zappiti player long ago. I now have around 20Tb of 4K files on 2Tb HDD:s both H.265 and H.264. I used to watch them from my HTPC in the theater and from my pc to the UHD TV with the MPC-HC player. Sometimes instead direct via USB to the TV Panasonic DX900. I have external HDD:s or I put the internal HDD:s in a cabinet when using USB....
In july I bought 2 Oppo 203 UHD BD players and found out that the image quality from my 4K files to the USB:s (both 2.0 and 3.0) is breathtaking! Better motion, clarity and depth than the other methods.
