Hi all,
Just want to know if anyone has done any 4k video yet using the H-265-Codec, and if PD13 will handle it from what i have read one need a very powerful computer, and I mean top of the range with a 900 series graphic card

can anyone enlighten me on this subject,

I have had to put my new Samsung NX1 Camera on the back burner until they get this codec sorted,
here is part of the review i read

( The extra required horsepower is a big issue because while every modern graphics card supports H.264 natively, hardware HEVC support isn't widespread. This requires software-based encoding and decoding, which is far slower. For example, even brand-new Maxwell 2 GeForce 900-series cards from Nvidia will only offer a mix of hardware and software support for HEVC. Worse still, in practice we couldn't edit the footage in either Final Cut Pro or Adobe Premier Pro. Forget editing—even playing back the footage on a PC was a pain in the neck.

The only ways we could view what we shot were directly from the camera (which was plagued by artifacting and choppiness) or using Divx 10—VLC, Quicktime, and other common players couldn't play the footage smoothly at all. And even with Divx the only computer we found that could run it was the Razer Blade Pro, a $2,500 high-end gaming laptop. Even our i7-based Macbook Pros struggled. HEVC footage is the future of 4K streaming, but with hardware support at least 18 months away we recommend using a 4K-ready external recorder or converting the footage to H.264 before trying to work with it.)

thanks for looking I hope PD brings out a patch that improves the H265 CODEC

No wonder, they are using Macs
My old Core2Quad computer with a GTS480 was able to play 4K smoothly in Windows Media Center Classic (CUDA playback selected).
Newer to me Dell T3500 (with a six core Xeon) and a Quadro 6000 doesn't break a sweat to play.
Newer gen i7 with a GTX970 is needed to do editing - Maxwell2 cards have a full h265 encoder inside, but is not yet fully supported in drivers. My guess is that it will come, and then maybe (not guaranteed) PowerDirector will support it.

However... 4k is overated.
- First of all, you NEED to have a 4k display. How many people have that?
- Second of all, even for 1920x1080, the viewing distance necessary to fully perceive the resolution was too small - most of the people have the view distance too big for their screen sizes, reducing the actual vision to some 720 or even lower. For a 4K perception, the screen has to be huge and view distance small. Nobody will follow this.

I will have to try and edit a 4K clip and encode it in h.265. Some of the people on a forum I go to are posting 4K clips on Vimeo and I can download a the original clip. I don't have a 4k screen or TV, but I just build a new system this week. I used the new i7 5960x on a Asus x99 board, but only got the GTX 760 video card. Might be a good test for it.
Intel i7 5960X overclock to 4 Ghz 16 GB of ram.

This morning a download a 4K video file from Vimeo. It was the original clip before Vimeo did there thing to it. Media info said the file was 3840x2160 pixels and bit rate of 119 Mbps. I imported it to PD 13 and produce it to h.265 mp4 1080p with a bite rate of 5050 kbps. It took PD 13 2 minutes 12 seconds to produce it.

The video clip was 1 minute and 23 second long. I don't know if that is good or bad. I have not play with the HEVC H.265. Oh the original clip file size was 1.16 GB and my produce file size was 52.6 MB. That was all cpu encoding.

Screen shot after PD 13 was done.
