Question to our GPU gurus.
I have some problems with 10 bit UHD HEVC 265 video that my GTX960 is unable to handle. Will tle GTX1050 do the trick and how much memory for video?
Eugene

128 apperas to be overkill even for 4K UHD.
HEC265 gives you a better image at a lower bit rate. For my 4K videos, increasing beyond 60Mb produces no further, readily discernable picture improvement. Even 35Mb looks ok in the absence of much motion.

In this mornings mail I got the samw exactly worded answer as well. If only more people asked for UHD authoring and burning, most are resigned that it may not happen.
If CL made this a self supporting program (as they have in the past), then it could be used with ANY OTHER EDITING PROGRAM !!!!!
And as a self supporting program it could be released at ANY TIME !!!
And I would gladly pay $$$$ for it!
So $%(%@! obvious!
That XF400 should last you a long long time as will my FDR AX100

Congratulations!
Any methods for UHD burning?
I hope DVDFAB UHD Creator will keept its promise and that sooner than later.
Then there is TSM2UHD, but it does not work with my 265 HEVC 4K produced by PD. Cannot get TsMuxer to complete it's job in the first step.
Both are a work in progress.
These are the first feeble attempts that I know about.
Very impressive camcorder, the XF400

Interesting things are finally beginning to happen in this field.
Google something like: UHD Creator.
4K burning is getting closer. Burning your own UHD video material to disc

There seems to be some debate as to whether shadow files are of any real benefit.
As a relative newcomer I always understood the value was that producing lower resolution files for use in editing when you might want to drag fowards and backwards on the timeline would produce a smoother and more responsive visual effect, but it now seems this may not be the whole story.
Issues of pc power - quantity of memory - power of GPU etc seem to bear relevance - and now Support are actually recommending turning off shadow files as a possible cure to the "Audio wave does not display in PD16" thread.
What is your opinion? Apart from the possible affect on the above threads issue - do shadow files really improve the visual appearance when dragging back/fowards through the timeline? Is available RAM an influence on the shadow file debate? Are other parameters of the host system relevant?
Like most - I love a smoothe scroll when dragging backwards or fowards on the timeline trying to locate a particular point, it feels and looks most professional, but is at the end of the day so much easier to work with than constantly wondering if the visual position you're at actually matches where the grabber is.
Try using NewBlue Titler Pro (even the free old v1.5) and you will get a beautiful demonstration of just how sweet live scrolling back and forward can be when the coders took the trouble to write sweet software. not that I am expecting PD16 to equal that demo, I still think smoothe scrolling is a very nice feature - but whether shadow files on any particular setup help or not is where I would value the thoughts of this forum.
Cheers
Alan.
The appearance is likely better w/o SF but a lot depends on your pc. Mine will do HD w/o SF but for UHD it is a must for anything longer than 10 min. See specs below. For most laptops it is a must.

Google TSM2UHD and you learn all about a TsMuxer modification by JDOBBS that allows burning of HEVC UHD Blu RAY.
Great news indeed.

Converting the frame rate from 60 to 50 or 50 to 60 or 25 to 30 etc will have a major impact on video quality, especially if there is motion. This jitter is unavoidable with this kind low cost software.
Make a 1 min test .
Stay with your orignal parameters, 30P or 60P

I have been shooting 4K MP4 at 100 Mb with a Sony FDR AX100 and after editing output in 265 at 60Mb. My Pc can do it in 2 to 3 times real time, work done by the GPU GTX960.
PQ is such that it is difficult to discern differences between MP4 original and the HEVC edited output.
As to NTSC/PAL, I own a lot of European videos, my 3 yr old 75" TV will play them all at the original frame rate without even a hint of flicker. I would never convert their frame rate.
BBC World II uses 24P, here too no TV flicker.
So I would stick with the 60P frame rate.
The only problem would be mixing videos shot by a friend of yours that uses 50 FPS

That is interesting about de-interlacing always,I did not know. Likely good idea.
Nothing is gained by storing videos on a SSD, a external regular HD will do just as well, just as fast for a lot less, better yet, use two for insurance.

264, pick 720x480 24fps. click + then video
It can be set to720x480x29.97P
You can also change the bit rate, that will determine your file size (and quality)
See if the TV will play that format, a pc will.
Eugene
@Eugene - THANKS! This is exactly what I was looking for! I just generated a clip doing that... It seems to still be interlaced, though. When I pause, the frame I see still has interlacing... and if I set VLC to do unconditional deinterlacing, it gets better... Would PowerDirector automatically de-interlace the AVI data if it was set to generate 30p output? I didn't see any option to specifically trigger deinterlacing of the video data itself. I'll look more closely in this area later today... But now I'm seeing more about how to do this stuff.
@Carl - yeah, I know the old interlaced history. : That's why I kinda want to get to progressive on these older videos. I generated a test on the 720x480 60i setting... it was reasonable... and interlaced... And VLC did a reasonable job of de-interlacing. So that's always an option.
One last question on this one (it's somewhat related to this subject so I think it's OK to continue on this thread).
I'll be doing multiple "batch production" runs to generate all video output files.
It seems that when I select, say, 10 "projects" for the batch, that they all default to generating using "MPEG2 720x480 60i."
This happens even if the individual projects themselves are saved with, say, my custom 720x480 30p setting.
Is there a way to set a 'default' so that it will use my new custom 720x480x30P output? Or whatever default ultimately decided to use for all these separate videos? Looking through the various options I've found, I'm not seeing anything...
Right now, I'm having to do a bunch of separate clicks and stuff to adjust each entry in the batch.
Over and over for each entry... it's kinda painful and repetitive. :
But this might just be how the batch production works... And if it is, life goes on.
Again, thanks!!!!!
Don
You may want to download MEDIAINFO a free program that will tell you exactly what format a video is. It identifies close to 50 items, like bitrate , frame rate, P or I, etc

TOMASC is correct, you do not want to change the recorded image format, it always is bad for PQ.
Use 720x480 30fps, 24fps will give you stutter. the 264 format allows custom frame settings.
Since you are not going to burn, the TV is the only criteria as to playback. Gives you far more latitude.
As to file size, storage is cheap, I would not worry about it.
Anyway , the obvious is to make some 1 minute test samples and use the one you like best.

Yes, it is burned as a file and some UHD players like the Samsung will play it as a file. HEVC works best, other UHD formats may have some hickups.
To my knowlledge the Samsung and the Oppo are the only ones that will play this material. Phillips will not.
I use a bitrate of 50Mb and up, the playback PQ is very close to the original. Surprisingly HEVC recorded on a 4.7DVD works fine too!
CL could design a UHD burning plugin, paid for seperately not part of a PD, that would also burn UHD files produced on other brand NLEs.
I use a 1 year old internal LG player/burner, it will read the data on ALL of my UHD discs but will ot course not decode. One, Rocky Mountain Express an IMAX copy is out of this world, produced on a 50GB dissc. Most others are 66Gb and the LG sees them too.
If you read the wish list you will find some good arguments why this would be easily to do, the file structure and names are the same as BR and only the content is different. And ony a few files are pertinent. Something along the line of TsMuxer.
Do not forget to put you name on the wish list please

Wow, thanks gang.
I'll sift through your technicals a bit later, sounds great!
To clarify, I'm not talking about camera footage. I do a lot of fractal animations/zooms; usually for an animation I render a couple thousand frames up to 20,000 x 10,000 px each, then I load those in PD as images and set each for a duration of "1" frame, so that there are 30 of those images a second (adding music and/or narration). So, naturally I'd like to render video that's the highest rez/quality possible, e.g. 16K or even higher. (PD7 didn't even have the ability to put a picture in for a duration of 1 frame; the minimum duration was 2! So I could only have 15fps animations which looked choppy. I did figure out a trick, though; I could produce the 15fps animation, then load that BACK in to PD and set speed to 2x, re-produce a final vid, but of course that lost a bit of quality to produce twice. Fractals have extraordinary detail and encoding can mutilate it.)
Since you like to have 8K, a step in the right direction might be to ask for 4K burning on the wish list. Just a wee step.
Happy Thanksgiving to All

Well, I am in the same boat. All my videos are in 4K and no means to put them on a BR like you can with HD BR. All we can hope for ist that an inovator like Cyberlink will add it to their features, like in PD17.
In the meantime I burn a UHD HEVC file to a BR disc and it works in a Samsung UHD player. No titles etc.
CL has a list were you can request any features for the next edition and please do so, the list will close VERY SOON.

Do you burn any of your edits to DVD or BR?
Eugene

Like how high is up?.
W/O any idea what you are editing it is hard to judge.And your PC too. I assume HD since you are not using shadow files.
I still have PD14 but my WOW moment came app two yeras ago when I added a GTX960 GPU that works well with PD 14.
Rendering a 90 min 4K video to 4k HEVC went from app 3 DAYS to app 4 HOURS ! The CPU at that time was an Intel i7 960, it was doing the rendereing. After installing the GTX960 CPU usage went from 90+% to less than 10%.

My favourite subject again
Why not have 4K burning as a seperate plug in, same as you now have for audio and video.
It would be worth a few hundred for those that really want it.
And it would be a killer if it is compatible with other editors like Pinnacle etc.
Similar to what TsMuxer does now for AVCHD and Blu-Ray, just add UHDHD.
Eugene
PS. And a audio level meter, I asked for that years ago. Thanks for the reminder Treysvideo.

Hi John -
The shadow files option is still in the same old spot - Preferences > General.
With PDR16, you can select the shadow file resolution. Screenshot attached.
Cheers - Tony
Well Tony, you now got what you had been asking for for many years, the ability to modify Hanumag

Thanks for the info.
There are now... WOW.......... 4 requests for UHD video on the future feature site, WOW.
That site had 16 users, requests for some items already incorporated and 1100 viewers.
Does that show that 25% of users requested UHD..............
It closes soon, so make your wish now, or you have to wait an other year, over 300 days!!
Still puzzled by the UHD burning absence in PD15. Should have been relatively easy to implement.
Would have been a nice feature for the CL advertising department to list in the "WE HAD IT FIRST" collum.
Just editing an other video of a very recent vacation cruise, I enjoy the editing just about as much as the original. And PD14 on my PC is so stable that I cannot remember the last crash I had. And 99% of my editing is in UHD.
That does not speak well for PD16, it needing over 20+ patches only a month after its debut.
