What is libx265 encoder codecs? Did you try it? Which software can use it?

[vhelp]

@ Marchand, ffmpeg libx265 works quite well. but you need to add a -preset name in there for maximum quality. i tried several variations without -present and i was not impressed. the quality had pixelation and other compression artifacts. but when i added a -preset ultrafast (my usual setting) (but, use the one you usually use in your test encodes) the quality was as good as x265 on its own. i did not do any quality comparisions between ffmpeg_libx265 and x265.exe or anything. i used the script in post # 19 above.

[Marchand]

Ok vhelp
Thank's

In case anyone has a computer powerful enough to play it at full 23.976 fps (I don't), here is a 4k encode. I managed 2.2 fps using ultrafast - crf=25 in ffmpeg 64-bit.

No, it's a trimmed section of a 4k mp4 I downloaded from youtube awhile back. I can't seam to find the original link, so it may be taken down now. I can post the trimmed source I used if you want.

No thanks. If it was uploaded to YouTube, it will certainly not be in a reference quality.

XP-compatibility is back

Many many thanks to Mr. Borho

[LigH.de]

And to Nabajit Deka who fixed the assembler register usage; and to everyone else who contributed solutions.

So x265 is already approaching the next milestone of version 0.9 ... soon™.

[ezcapper]

very simple command that has worked with all of my videos. Good if you don't want to/know how to tinker around too much but just want to test libx265 problem free.

ffmpeg -i D:\1.avi -pix_fmt yuv420p -c:v libx265 -x265-params crf=28 -c:a copy 2.mkv

The only thing you have to change is the name and location of your input file and the crf number to whatever quality setting you want. The "-x265-params crf=28" part is redundant and not necessary since 28 is the default quality setting, it's just an example. The "-pix_fmt yuv420p" is the most important line to improve compatibility as x265's default input colorspace accepted is i420. I have not had good luck changing the default, it is easier to just comply to it by using the command. You can replace bitrate instead of crf if you wish with "-x265-params bitrate=1500". The pause button on the keyboard pauses the encode, enter resumes.

If you would rather use x265.exe which is updated more often instead of libx265, I can post a bat file for that if anyone needs it. You pipe the file from ffmpeg to x265.exe.

Alternately, to avoid the command line altogether you can use libx265 with the avanti gui, which works well. There is an option to set the pixel format to yuv420p on the main page.

Handbrake nightly builds are the simplest gui for x265 but I don't like the output quality. Hybrid is extremely customizable, you can get whatever output you want, but it is a little bit slow. Mediacoder requires the internet to finish the encode, but doesn't tell you until you are 99% finished.

Here is a link on how to make the .bat file if you want to use x265.exe directly in the simplest way.
