Hello. Of course it is possible, but I don`t think that it`s needed. 10-bit
encoding is not for "every day using", and if you really need 10-bit for some
reasons, you can manually replace existing 8-bit x264.exe with 10-bit one (see
\apps\x264 folder or drag-and-drop appropriate version of x264.exe into preview
area).

Hello.
Thanks for your answer. I'm gonna do that.
Reason why I asked is because the 10 bit depth x264 offers a really better
video quality and also it encodes faster than the 8 bit depth x264.
As for decoding, I plays great with the latest CCCP build on windows 7.

Hello again.
I did tried your suggestions, while they worked, they weren't perfect.
First, I can't properly tweak the settings (like CRF) and also choose a 10 bit
level (High 10@L4.1 or High 10@L5.1).
So the encoding results aren't exactly what expected when compared with another
encoder.
Another thing, the current version of xvid4psp can't decode a 10 bit depth x264
encode (if you wanna re-encode a 10 bit depth to 8 bit depth), it shows a grey
image. In order to get it to work, ffmpegsource has to be replaced with a newer
version (that supports 10 bit) and the decoding options for mkv and mp4 have to
be changed from directshowsource to ffmpegsource2.
So that's why, it would be nice add a proper 10 bit option in the encoding
settings, and if it was possible to add an option to use ffdshow as decoder it
would be great too.
I'm asking this because CCCP now released a 10 bit depth filter pack version,
and the fansubs groups started to move to 10 bit, it won't be long before they
stop doing 8 bit encodes.
Thanks again for your hard work and support. ^^

Hi.
Well, just tested it a little bit.
"I can't properly tweak the settings (like CRF) and also choose a 10 bit level
(High 10@L4.1 or High 10@L5.1)." - not sure what do you mean by "tweak the
settings"; if you want High10 profile - just leave it as "Auto", or add\edit
"--profile high10" to CLI - both will work the same way.
Current versions of FFMS2 (r484, r494) can`t decode 10-bit samples, it requires
colorspace specifying when calling. Without it we will get an error
"FFVideoSource: No suitable output format found" - I don`t know is it bug or
not, so not gonna change anything about it untill it will be clear.
"and if it was possible to add an option to use ffdshow as decoder it would be
great too." - no, its impossible. Well, it is possible by tweaking the
registry, but this is not what XviD4PSP must to do. If you want to use
DirectShowSource and if you want it to use ffdshow, then it is your mission to
tweak your (system)decoders merrits\settings accordingly (using Win7DSTweaker,
DSFMgr or something similar).
I will add a "--output-csp" key and "High 10 Profile" option, probably it will
be good to auto-use a 10-bit encoder when the user switching to this profile.
But in this case we must have 4 different version of x264 (32bit, 64bit, 10bd
32bit, 10bd 64bit) - nothing special except a few extra mbytes for the
installer :)
"Thanks again for your hard work and support." - well.. my support currently is
very limited. We need a fresh blood, a new programmers! :D

Thanks for your reply.
By tweak I meant, CRF for 10 bit goes up to 61 (50 for 8 bit). As for the
level, I'll try to leave it at auto and see how it ends.
As for FFMS2, I replaced the one from xvid4psp with this one
http://sourceforge.net/projects/mplayer-win32/files/FFmpeg/git-N-30656-g23a29a3/
and that way I was able to re-encode a 10 bit encode into an 8 bit one without
problem, I just had to select FFMS2 in the decoding option.
Thanks for adding the "--output-csp" key and "High 10 Profile" option, it will
be useful. ^^
Greats

Oh yes. You're right about the settings, I didn't know about this.
-q, --qp <integer> Force constant QP (0-69, 0=lossless)
-q, --qp <integer> Force constant QP (0-81, 0=lossless)
--crf <float> Quality-based VBR (0-51) [23.0]
--crf <float> Quality-based VBR (-12-51) [23.0]
--qpmax <integer> Set max QP [69]
--qpmax <integer> Set max QP [81]
I'm not sure yet how to resolve it..

http://rghost.ru/private/15091431/6f5e09f4405796ce94c7750d62cc5fa8 - here is
exe from r240. 10-bit depth x264.exe must be placed to \apps\x264_10b folder.
Different limits\defaults also must work.

Thanks a lot.
It works better now. Just the max CRF needs to be modified also, 8 bit has 51
max and 10 bit has 61 max.

You`re welcome :) As stated in --fullhelp for a 10-bit version (2019 at least),
CRF range is -12-51, so maximum is the same (51) as for 8-bit. You can encode
with (say) --crf 57.0 and then check with MediaInfo that this value was
lowered\limited to 51.
Original comment by forc...@gmail.com
on 20 Jul 2011 at 2:42
Yes, you are right, they changed it again.
But, CRF -12 won't work. http://pastebin.com/uicpgNrj
And why I try to encode using command lines it tells me this:
"x264 [error]: high10 profile doesn't support lossless"
-11 is the maximum you can use (tried -11.1 and crashed also with the same
error)
So, I think, that the lossless option should be grayed out when using High 10
Profile.
Original comment by Okocha1...@gmail.com
on 20 Jul 2011 at 5:04
CRF = -12 (from -12 to -11.1) - is lossless range for 10-bit. So you have some
problems (crashing x264) in 10-bit Lossless mode. Sorry, I can`t help you with
this. You better ask about it someone from the x264 team. But first try 32bit
10bit-depth version or version compiled by someone else (from here for example
http://www.xvidvideo.ru/x264-video-codec/x264-video-codec-rev-2019-x86-x64.html)
. Anyway, this is not the reason for graying out Lossless checkbox if 10-bit is
selected.
How did you get this error "x264 [error]: high10 profile doesn't support
lossless"? It could only happen if you passed --crf -12 (or --qp 0) and
--profile keys both at the same time. But XviD4PSP (uploaded above) will
remove* any --profile keys from the command line if Lossless mode is active.
Well.. It must, at least :D
* - remove from the command line that will be passed to encoder right before it
calling; your encoding preset remains unaffected.

When I select lossless, xvid4psp automatically selects Constant Quantizer, if I
choose Constant Quality it refuses to use lossless.
In order to get CRF -12, I've to do like that:
Select Constant Quality, then choose high10 profile, then set the CRF to -12
and then the lossless button sticks from itself
"--crf -12.0 --preset medium --profile high10 --ref 8 --deblock -1:-1 --b-adapt
2 --trellis 2 --no-fast-pskip --psy-rd 1.0:0.1 --partitions all --me umh
--rc-lookahead 50 --extra:"
I can't choose CRF -12 without having chosen profile high10 before.

Ok. Do you have any problems right now? Because all what you described above -
this is how it should be, and I don`t see any problems here. 10-bit x264
crashes for me too with your settings (from this log
http://pastebin.com/uicpgNrj). But since you`re trying to encode in Lossless
mode, most of this settings is probably pointless anyway, so leave just "--qp 0
--preset medium --profile high10" on the CLI tab, the key "--profile high10"
will be removed from this line when encoding starts.
Original comment by forc...@gmail.com
on 21 Jul 2011 at 10:29
OK.
I tried like that:
"--qp 0 --preset medium --profile high10 --level 5.1 --aq-strength 0.6
--deblock -1:0 --b-adapt 2 --no-fast-pskip --psy-rd 0.4:0.0 --threads 4
--partitions all --me umh --extra:"
And the error is still happening. If I remove --profile high10 from the profil,
then xvid4psp encodes using 8bit depth x264.
But what's strange is that http://pastebin.com/PRKdM9NB (x264 [info]: profile
High 4:4:4 Predictive, level 5.1, 4:2:0 10-bit)

But I'm only using lossless for testing purpose and to find possible bugs.
I don't use it normally.

Oh, btw, this is unrelated, but I tried a new MT version of avisynth which can
be found here http://xhmikosr.1f0.de/index.php?folder=YXZpc3ludGg=
So far that version works great but only with new processors.
That site has some nice patches

"And the error is still happening." - x264 crashes, I can`t help you with that..
"If I remove --profile high10 from the profil, then xvid4psp encodes using 8bit
depth x264." - yes, you don`t need to remove this key. But XviD4PSP will remove
it when encoding starts, if Lossless mode is active (because --profile is
incompatible with Lossless and --profile high10 is only required to determine
what version of x264 must be used).
"But what's strange is that" - and what`s strange? x264 crashes in 10-bit
Lossless mode :) Or what?
P.S. New MT-builds of AviSynth 2.6 also can be found here
http://forum.doom9.org/showthread.php?t=148782 , but I didn`t test it myself..
Very interesting, what`s the difference between current 2.5.8 MT (by SEt) and
2.5.8 MT from your link, except compiler.
Original comment by forc...@gmail.com

Yes, whatever is chosen, x264 crashes in 10-bit Lossless mode. Can't say why
though.
As for xhmikosr avisynth version, it seems to have been tweaked for Intel
processor.
But I'm gonna test the aviSynth 2.6 MT and let you know, but it may need a
couples of encodes before I can give you an opinion.
So, I think the only thing left to do for 10-bit depth would be the decoding in
case someone wants to re-encode a 10 bit to 8 bit.
I tested xvid4psp 6 and it seems this one can decode 10-bit encoded videos, but
I can't say what filters it uses to do that.
Also, I've to say that I'm not really found of xvid4psp 6. It's not user
friendly and lacks advanced features.

AviSynth 2.6 is still in Alpha stage, so be carefull..
Decoding 10-bit files is possible with DirectShowSource and DirectShowSource2,
but you must have all requiered codecs\splitters installed and properly tuned.
FFmpegSource2 also can decode such files, but currently it can`t be used
without forcing the colorspace (autoforcing is broken in FFmpeg code, see here
http://forum.doom9.org/showthread.php?p=1513636#post1513636). So.. 1.) someone
will fix this bug or 2.) I will add an option to forcing the colorspace or 3.)
you can modify \dlls\AviSynth\plugins\FFMS2.avsi (find colorspace =
default(colorspace,"") and put YV12 between quotes).
XviD4PSP 6 is based on FFmpeg libraries, so I think it decode such files the
same way as FFmpegSource2 does. I have very outdated version and don`t want to
upgrade (don`t want to install Framework 4.0 :p ).

I tested a bit avisynth 2.6 MT, what I can say is that it is a bit faster than
2.5.8 MT but crashes more often. So it's not good for now.
Thanks for your trick (\dlls\AviSynth\plugins\FFMS2.avsi), I modified it.

No Problem :) I`ve made some more changes to x264 settings window, adding
--tune and --subme 11 (r2036+). Not committed yet.

OK, thanks a lot.
I tested it and the tune options are working, when selected they enable,
disable and modify stuff were needed.
--tune grain will be really useful for some movies and animes.
--subme 11, I can't test that one yet, the new revision of trellis isn't out
yet (I think).
