I think the biggest asset in my setup of PD14, is its ability to fully make use of the GTX960 abilities.
Still amazing to see it encode HEVC 4K in an hour what used to take days.
There is free software called MEDIAINFO it will give you data of a video file, better than WP
Tony, that would be similar to my "harbor shot". As mentioned I was rather shocked as to how bad it was, primarely because that had never happened before.
I will start using custom settings too from now on to maintain the 60Mb that the camera puts out rather than go down to 50.

Thanks good to know. Maybe that fact might be mentioned too?
I was referring to posts like "all my paid CL apps are now gone" etc

Fairly often the question arises as to what PC to buy for video editing.
That is especially important when editing 4K inluding the around the corner HEVC UHD BR format.
My personal experience favours the tower desktop design, making it easier to update and customize.
My computer, specs below, was bought in January of 2010.
By replacing the video card with a GTX960 and the C drive with a SSD, it was possible to increase the performance with PD14 to near the state of the art as far as video editing is concerned.
This resulted in vastly faster 4K rendering, in the case of HEVC from days to minutes. 60 min vs 2 days! All for under $300.
And the HD display was updated with a UHD 24" Viewsonic HDMI 2.0 monitor.
With a laptop that would not have been possible.
Not to mention that there are few if any laptops that can challenge the performance of a desktop for video editing. And most likely none that can render the new UHD HEVC format at all, or within a reasonable time. The design bottleneck is much higher GPU power consumption and the resulting heat and lower battery life.
Any thoughts ???

Bought my PC, specs below, in January of 2010.
Before PD14 I was looking into the purchase of a PC with a faster CPU, but decided not too because of PD14 making use of available GTX960 features.
So by simply adding a $200 GPU card and a $90 SSD for the C drive, my over 5 year old computer is close again to the state of the art as far as video editing is concerned. By that I point to the vastly reduced rendering times. Most other PD14 editing functions would not be materially improved by a faster CPU anyway.
An other update was the shift from a 23" HD monitor to a 24" UHD Viewsonic HDMI 2.0 monitor
WOW

Dafydd,
on your beta patches, you might consider putting in a caveat, like
"back up your PC before doing this"
Not having the guts to try beta patches I have a question. After installing the patch, can you revert to the previous version by installing the previous patch?

Yes, that copter shoot looks pretty cool.
I actually do not follow my own rules by using 50Mb, the default PD14 rather than the cameras 60Mb.
A month ago I was shooting the take off in Juneau harbor of a small plane. The entire water surface had very fine ripples on it as I followed the plane with the camcorder.
Later looking at the scene on a 4K PC monitor I could not believe my eyes, the shot was unusable, full of "mosquito noise".
After several thousand 4K shots this was the first time that happened, most likely caused by the rippled water. Just too much picture detail and not enough band width to carry it. Very much like the copter shot.
The camera allows 100Mb, a number of members on the AX100 forum too feel that 100 is overkill, so the final output for me is 50Mb VBR.

For a 4K video and a frame rate of 30 the bit rate of 20 Mb is much too low.
The pixelation is typically of a too low bit rate.
I have a 4K camcorder, it uses 60Mb, that is the minimum for an image that does not have too much motion. Also use variable bit rate if you have it.
What is the bit rate etc of the original video? As a rule, do not change the original format to get best possible PQ.

Bingo!
I had Google Drive on my PC w/o knowing. Works fine, able to mail and download the original video files.
Thanks Tomasc

Actually the SSD drive is 3 partitons, C for important programs like win7, PD14 MSxx etc, D for less important items like video players, format factory, email files etc, and E for PDS files from PD12 13 14.
My weekly backups using TrueImage are the entire SSD drive, C D E, NOT incremental. Of the total 250Gb SSD only about half is used.
In 3 or so month time I delete some weekly backups (on external drives normally powered down) and keep 1 for each month, after a year one for each 6 month. I can still restore my PC to what it was on day 1, over 5 years ago, or the day when I first installed PD12. Storage is cheap!.
And if I had to go to day 1, it would be on a different drive, the current drive unplugged and sitting on a shelf ready to go back in operation within a few minutes.
And, to simpify and speed up editing, the other two HHD's are partitioned as well. In fact of the over 12 hard drives I use, depending on what I am doing, only two I think, are NOT partitioned.
I learned all this the hard way in over 16 years of PC video editing, like OH NO, the C drive just died, have to install everything all over, lost all email addresses. Been there, done that. But not again, ever.

Some members use beta patches to help CL evaluate software patches. Reading the forum, predictably this involves problems like having to re-install previous versions etc
This can be avoided by the simple expedient of a C drive backup made before the patch is installed. There are many free programs available, I have used TrueImage for at least 12 years with excellent results. Still use Ver 2010.
I have gone a step further by installing 3 Kingwin 3.5" Internal Tray-Less Hot Swap Racks on my desktop computer so that the three HDD can be swapped in the time it takes to re-boot. Cost under $20 ea, have used them for at least 7 years.
So to test a patch (or other equally dangerous excercises) a clone of the C drive is made, that clone is then used for the evaluation, reverting to to the original version can be done in minutes. My C drive is a SSD drive and kept very lean by using the 2 other removable drives to store videos, data etc.The C drive holds programs only.
So cloning the SSD C drive can be done in minutes, I do that every few weeks including weekly C drive backups to two external drives.
My SSD drives have a 3 year warranty, I was assured that they would last longer than that, even with the bi weekly cloning. And who cares with a clone and backups on hand. I paid less than half for the 250Gb SSD drives than for the 2 , 300Gb 10 000 RPM HDD I used before .

I have access to unlimited Amazon cloud storage, it works great when up/downloading regular HD material but not when using 4K. The videos in each case are from a camcorder.
I wanted to pass on some original 4K camera clips, without the heavy compression YouTube employs.
Hopefully not too far off subject.
Any suggestions?

No 4K at all.
I confuse easily, you want some 4k AX 100 material?. If so can you add a AX 100 location.
Eugene

No Sony FDR AX100 4K material ? I assume you have one or samples.
Great idea to provide samples from known sources and formats AND original QUALITY rather than Youtube downloads.

Shadow files or Proxy Editing Files, are lower resolution to reduce CPU load while editing.
The original resolution, imported files are used when rendering the output to DVD or what ever.

4K HEVC MKV files? 30 min long? With transitions, titles etc. ?
When I try that, PB from the time line will stutter w/o SF. Producing, rendering 4K HEVC is not a problem and works at app double real time.

PD14 will not generate shadow files from imported 4K 265 HEVC material
W/O those files it is impractical to edit 4K HEVC files.
However PD14 will import and convert that material to SD format, those files can then be imported into PD and edited normaly.
Shadow file generation is turned off.
Replacing those SD files with the original 4K HEVC will allow final output produce in that format using the same file name.
Using a GTX 960 GPU will do both conversion and produce in about twice real time, with hardware encoding, (no transitions etc used).
This method has been mentioned a few times on this forum during the past years as a means to speed up the inherently slow PD shadow file generation.
It will also allow editing of 4K HEVC video in PD14 if a GTX 960 GPU is used.
The process works on my 5 year old computer and just about as fast as editing in 4K 264.

I believe that PD14 is not suitable for editing 265 HEVC because it cannot generate shadow files from that format at this time. And without them it is not really possibe to edit those 265 files even with a fast PC.
PD14 makes use of the GTX 960 codecs, I found that it is possible to produce a 1 minute 265 output file just as fast (1.7 min) as a 264 file when editing 264 material with outstanding quality.
The 960 does nothing however for playing the video on the time line, at least on my set up.
There may be a way to edit 265 video by first converting to SD and edit that, then substitute that file with the original 265 video and using the same file name.
It took 2 min 8 secs to convert a 1 min 4K 265 HEVC MKV file to SD using PD14, that SD file could then be imported and edited and replaced by the original file in produce. Hardware video encoder mode was used.

Amen!!
Would be nice if SF generation could make use of the codecs in 9xx GPUs.

Jeff, Paul, Tony
At the moment the lack of SF for 265 HEVC does not impact me. However that will change since they now take no more time and look just as good as 264 videos, using the GTX9XX codecs. Also we are getting closer to UHD BR.
I have used the file substitution method a few times when in a hurry. Usually I just wait or let PD generate SF over night.
I did look at the PD13 post, nothing has changed. Unfortunately.
Eugene

Jeff that would be a good idea. Hopefully Dafydd will take note and pass it on.
The other problem is the speed at which the SFs are generated.
