Hybrid(Windows/Linux/Mac): Input -> x264/x265/Xvid/VP8/VP9

Hi
Im not too familiar with x265 encoding !!!
I wanna encode a video by x265 with this detail:

so what should I do ?
cause I raise up bitrate but nothing has change !
sorry for my bad english !!!

[Selur]

a. Assuming the problem is caused by banding in dark scenes (which is a weakness of current x265 8bit encoding) using 10bit instead of 8bit should help
b. otherwise using '-tune grain' and or modifying the adaptive quanitzation strength should help with bit rate distribution
as a side note: Better stick to aq-mode=1 instead of aq-mode=2 and in general using more bit rate will help.

Cu Selur

[litoo]

tnx it was very helpful !
one more question:
Is there any preview in your programe ?
for example:encode 30 second of video with current encode option to see how its look like !!!
sry for bad eng !

[Selur]

If your input has multiple chapters, you could only encode a single chapter (Main->Primary Input Selection->Chapter) or you could enable cut support (Config->Internals->Cut Support) and select a start&end (Main->Handling->Cut).

[Gravitator]

Hi litoo,
You should take a look at my settings for dark video > result (fast coding & quality).

[Gravitator]

aq-mode=1 is now the default in x265

newbie here to Hybrid. Worked on first attempt after installation but still crashed after halfway encoding. Then never worked again, crashing at startup.
I uninstalled but even that was not successful as a reinstall indicated the program already existed in C:\Program Files\Hybrid
I guess there's no way to completely uninstall / reinstall , is there?

why does it work perfectly for some and crashes all the time for others.
I'm on an i5 dual 2.67ghz, 4gb memory.

[Selur]

Normally the uninstaller should deinstall everything. (it does here)

A crash half way through a job might be related to:
a. not enough memory. (check you memory usage during encoding)
b. a buggy source
c. some strange virus scanner (from time to time McAfee seems to cause problems)
d. hear problems
e. some thing else
-> can't really say without a debug output (see: http://www.selur.de/support)

Cu Selur

[texas1]

hmmm... never even thought about McAfee. Maybe that's why some people crash at startup while others have perfect operations.
Memory was good, about 2.0gb - 2.5gb.

[Selur]

I just from time to time spend days hunting strange, for me not reproducible bugs, and in the last few month, one of the main culprit after memory or heat problems was McAfee. (no clue what they do, but my guess if that they somehow meddle with the inter process communication of Hybrid and the pipes between decoder&encoder)
-> no guaranty that it is McAfee, but especially crashs in the middle of a conversion are normally not directly Hybrids faults.

Hi
I faced with a strange problem !
when I Encode a video with x265 on Hybird its ok !
but problem is here that there is nothing in encode option when I look at detail with media info !!!!
this problem happened very suddenly due to change some of the encode option that I cant remmeber them now !
so whats problem about encode option not showing in media info ???
sry for bad english !

[Selur]

Hybrid itself doesn't offer an option to modify whether or not the encoding settings are embedded.
The .265 files Hybrid produces still have the info in them.
-> x265, when used with Hybrid does embed the SEI info you want.

If such a raw .265 file is remuxed with:

• tsMuxer, MediaInfo does still show the details. (this happens if .m2ts is used as output)
• MP4Box, MediaInfo does still shows the details. (this happens if .mp4 is used as output)
• MKVMerge, MediaInfo doesn't shows the details. (this happens if .mkv is used as output)
  If the video stream gets extracted from the mkv file, all details are gone.

Seems like mkvtoolnix doesn't preserve the SEI infos for HEVC streams and thus MediaInfo doesn't report them.
-> So either don't use .mkv as container, or report the problem that mkvmerge doesn't preserve the SEI info from HEVC streams to the mkvtoolnix developer. Since this is not a bug in Hybrid there's nothing I can do about it.

You are absolutely right !
Now I remmember that since I change the container this problem happen !
anyway tnx for all of your hardworking !<3

[sophisticles]

Have you removed support for x265? For some reason the last 2 builds of Hybrid I tried don't seem to have x265 available.

[Selur]

will be fixed in the next release (tomorrow), accidentally the version id couldn't be read which is why Hybrid assumed x265 wasn't present

[sophisticles]

Before you release a new version I found an issue that you may want to look at. I downloaded the file named "Beauty" from here:

http://ultravideo.cs.tut.fi/#testsequences

Beauty 1920x1080 8bit YUV Y4M (877.22 MiB) <--Specifically this one.

When I try to import it into Hybrid it incorrectly sees the properties:

As you can see it sees it as an interlaced bff and it also sees it as 30fps but it's obviously 120fps and progressive. This is repeatable across all 120fps y4m sources I tested.

Thought you should know.

[Selur]

Okay, got it, inside the 7z archive

[Selur]

Not A Hybrid bug, looking at the file with a Hexeditor shows:

YUV4MPEG2 W1920 H1080 F30:1 Ip A0:0 C420jpeg XYSCSS=420JPEG.FRAME

and F30:1 indicates 30 fps not 120fps.
looking http://wiki.multimedia.cx/index.php?title=YUV4MPEG2 you see the content is flagged as 30fps (F30:1) progressive (Ip).
But you are right that the interlace detection fails and detects the content as interlaced. (not sure if I can fix that, 600 frames is a rather short sequence and on short sequences the interlace detection isn't that reliable)

[sophisticles]

You're right, I should have checked Media Info, it also reports it as 30fps. I wonder why these guys claim it's 120fps and why it plays as if it's in slow motion.

[Selur]

Since the scene is rather artificial it's hard to guess if 120fps is the correct fps, but changing the fps to 120fps is easy with a hex editor.

[sophisticles]

I found a new oddity, when I load up Elephant's Dream y4m, choose x265 and try to make any changes to any setting I get a pop up with the message:

And it also says 'error'.

It only happens if I attempt a bit rate based encode, no error on CRF based encode.

[Selur]

Got it happens only with 1pass average bitrate, it's a typo should be 'strictCbr' instead of 'strictCBR'. -> fixed locally.

[sophisticles]

When are you releasing a version with the fix?

[Selur]

Not sure. If you tell me your OS I can compile one for you.

[sophisticles]

Win 7 64bit.

Thanks.

[sophisticles]

Latest version complains about out of date AviSynth, disables it. Since it comes included with your software I thought you should know.

[Selur]

Ahhh,.... forgot to update the version.txt -> simply change 20150119 to 20150208 and everything should work again
(uploaded a fixed Windows installer to my download page)

[sophisticles]

Found a much more annoying bug, for some reason installing Hybrid results in a avisynthPlugins folder where I don't have permission to write to the folder, which results in not being able to save any modifications to version.txt or even copying a new file into that folder. This despite being logged in with an Admin account.

[Selur]

Strange works fine here. -> deinstall Hybrid, download latest version again from selur.de/downloads and install that version

[litoo]

Hi Selur
few weeks ago you tell me that the not showing video info when you use mkv as container is from mkvmerge so I send an email to them and they
say its a bug in GUI and they gonna fix it in future... stil nothing happen !
yesterday I want to download a movie so go to this site => http://psarips.com/
they encode the movie & TVshow in x265 mostly mkv ! I download my movie and when I check media info
there was encode info however they use mkv for container !
how it is possible ?
here is the movie info :
