Ut Video Codec Suite - a new lossless video codec for Windows! [Archive] - Page 3

How is Ut Video Codec Suite 7.0.2 compared to MLC 0.7, cause I couldn't install it on Windows 7. Might be a workaround to make it work, but I wonder if it's worth it... I'm new to lossles codecs, so far MLC is the only one i tried (not famous as others, i know - but I heard to many bad things about the rest). Since is "lossles" I don't see any room for quality comparisons, so that leaves Encoding speed, compression and end results (as in "completed successfully").

I can't get UT 7.02 to install on Windows 7 either, but version 6 works just fine. Hopefully the author will fix this (hint, hint).

I haven't tried MLC, but UT is much faster than either Lagarith or Huffyuv (about 2x as fast as either), at least on a Core i7. It is the best lossless codec I have tried.

I translate and reprint the content from author's blog (http://umezawa.dyndns.info/wordpress/?p=1468).

January 22, 2010
I have heard the case of failing in the installation on windows7 several times before.
Houever, the cause doesn't turn out.
Then, I want to ask users for cooperation in the investigation.

Respondent to a survey:
User of windows vista/7

How to:
1: Uninstall UtVideo that has already installed (Please use the control panel).
2: Install ver.6.1.0
3: Use vcavail.exe and confirm whether UtVideo can used.
4: Do from 1 to 3 of ver.7.0.0 , ver.7.0.1 and ver.7.0.2 similarly.

Content that should be reported:
1: your windows version (vista or 7 , 32bit or 64bit)
2: Video codecs that installed beside UtVideo.
3: whether to complete the installation of UtVideo safely.
4: whether UtVideo can be used ( result using vcavail.exe ).

note:
・Please uninstall all UtVideo before the investigation.
・Please use vcavail.exe for the check on whether UtVideo can be used.
・The user of 32bit windows must install only Utvideo for 32bit.
・about ver.7.0.0 , ver.7.0.1 and 7.0.2 ,the user of 64bit windows must install only Utvideo for 64bit
・The user of 32bit windows must use only vcavail-x86.exe.
・The user of 64bit windows must use both vcavail-x86.exe and vcavail-x64.exe.

link:
vcavail.exe (http://umezawa.dyndns.info/archive/vcavail/vcavail-20100121.zip) (tool for investigation, the installation is unnecessary)
UtVideo ver.6.1.0 (http://umezawa.dyndns.info/archive/utvideo/utvideo-6.1.0.msi)
UtVideo ver.7.0.0 for 32bit (http://umezawa.dyndns.info/archive/utvideo/utvideo-7.0.0-x86.msi) / for 64bit (http://umezawa.dyndns.info/archive/utvideo/utvideo-7.0.0-x64.msi)
UtVideo ver.7.0.1 for 32bit (http://umezawa.dyndns.info/archive/utvideo/utvideo-7.0.1-x86.msi) / for 64bit (http://umezawa.dyndns.info/archive/utvideo/utvideo-7.0.1-x64.msi)
UtVideo ver.7.0.2 for 32bit (http://umezawa.dyndns.info/archive/utvideo/utvideo-7.0.2-x86.msi) / for 64bit (http://umezawa.dyndns.info/archive/utvideo/utvideo-7.0.2-x64.msi)

Translation from author's blog
This change point is only a change of the installer.
If the codec is not registered to your system with this installer,please double-click utvideo-x86.reg (or utvideo-x64.reg).
reg file is in C:\Program Files\utvideo .

Hi UMEZAWA san!
In this thread,
http://forums.virtualdub.org/index.php?act=ST&f=6&t=16116&st=0

squid_80 compiled a version of Huffyuv that could accept the HDYC output from the Blackmagic Intensity capture card.
There was some problems, as
>>>
the BlackMagic codec uses Rec. 601 coefficients if the width is 720 or less, and Rec. 709 coefficients if it's greater than 720
>>

squid_80 responded
>>>
for SD resolutions the intensity only offers UYVY. For 1280x720 and 1920x1080 it only offers HDYC. You can request UYVY@HD using the set custom video format dialog and it will succeed, but still delivers HDYC (or occassionally a blue screen error, something about driver has locked pages IIRC).
>>

I do not have access to my PC at the moment, and I will try Ut with Blackmagic Intensity and Virtualdub for capture in a few days.

I was basically wondering if you have tried Ut codec with HDYC input and if it works fine that way..

For Intensity and virtualdub capture, another important issue is from here...
http://forums.virtualdub.org/index.php?act=ST&f=6&t=18348

described well here..

http://www.etfinder.net/capturepics/

It looks that either Virtualdub or Huffyuv (or both) mess up the HDYC colorspace conversions.
So UT Video may need to be checked with color bars from a camcorder to confirm that the color values are correct..

>>>
I'm beginning to suspect that the issue is aliasing between the HDYC and UYVY formats. The HDYC format is a similar format to UYVY, except that it uses the Rec. 709 (HD) color space instead of Rec. 601 (SD). It looks like you have a couple of programs/codecs involved that are attempting to handle HDYC by simply pretending that it is UYVY.
>>>

>>>
Okay, I discovered the solution: Enable the filter chain, leave "Skip 24-bit conversion" unchecked, and clear the filter list.
This provides Huffy with 24 bit RGB I guess.

Bad news - it still doesn't work for me. Even after running the registry file it does not appear. I reverted again to version 6.1, which works fine.

Here is the error I get if I try to manually register the DLL (using regsrv32). My user is an Administrator and UAC is off:

"The module utvideo.dll was loaded but the entry point DLLRegisterServer was not found. Make sure that utvideo.dll is a valid DLL or OCX file and then try again."

For all users who meet problems with the official MSI installer, i have created a little package for you including latest 7.0.4 codecs, a batch file, an inf script and all the other files from the author.

Open a command prompt (in admin mode for Vista/7 if UAC enabled) and run the batch script "install.bat" : il will copy codec files to the right directories and then call the inf script to write all the necessary registry entries, including uninstall entry in add/remove section of the control panel.

For 32-bits systems (9x / NT) : install only 32-bits version of the codec
For 64-bits users (XP / Vista / 7) : install both 32 and 64-bits versions of the codec

Register DLL file with full path name.
Fix significant performance decrease in Athlon/Phenom-series processors.

Thanks for continuing to develop this. I still am unable to get any version after version 6.1 to register on a Windows 7-64 bit machine. I have tried all the different versions posted since then, including the special version which Leeloo Minaï
built. I am really sorry about this, especially as I would like to get some 64-bit version of UT Video to work. If there is anything I can do to help testing please let me know.

On Windows XP 32-bit it installs perfectly.

JoeH : what program do you use to encode and is this a 32 or 64-bit version ?

I will check again my script, i didn't try yet the last release of utvideo codec.

JoeH

27th April 2010, 07:05

I use VirtualDubMod, but also have VirtualDub (32-bit) and VirtualDub (64-bit) installed. If I can get UTVideo 64-bit version to register, I will use VirtualDub 64-bit.

From the error messages that Windows gives if I try to manually register the codec using regsvr, it seems to me that the problems is that Windows is not recognizing it as a valid DLL file. So, from the little I know anyway, I don't think the problem is the install procedure / batch procedure, etc., but is some change in the code or compilation that is making some Windows installations think the DLL file is invalid. Just a guess.

VFW codecs aren't installed by registering them.

Midzuki

28th April 2010, 04:50

VCM and ACM codecs must be registered through regedit —

— either manually,
or by double-clicking a properly-written .reg file.
A .INF installer will register the file(s) and will copy it/them to the system directory.

JoeH

28th April 2010, 17:02

OK, thanks for clearing that up. So, it's not a regsvr incompatibility then anyway.

Boolsheet

28th April 2010, 17:35

Edit: The VCM interface was moved from utvideo.dll to utv_vcm.dll in 8.5.1 version and above.

Have you checked the registry if there are the strings vidc.ulrg, vidc.ulra, vidc.uly0 and vidc.uly2 with the value utvideo.dll in "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32"?
The 32-bit codecs on 64-bit Windows are in "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32", but you already said they're working.

http://img168.imageshack.us/img168/184/vidc.png

Check C:\Windows\SysWOW64 for the 32-bit utvideo.dll (126'976 bytes - MD5: CC280F83C3BEE5E122F2A3B69D224507)
and C:\Windows\System32 for the 64-bit utvideo.dll (133'632 bytes - MD5: 0FB9C204339909A6FFB2075E1B30E98F).
Sizes and hashes are for version 7.1.1.

That should be all you need to get it working.

JoeH

29th April 2010, 19:25

Thanks for the info. I checked, and all registry keys and files are exactly as you stated. However, the UTVideo codecs do not appear, neither in the 32 bit version or the 64 bit version.

When I said that the 32 bit version appeared, I was referring to when I install version 7.1.1 on a 32-bit operating system. On Windows 7-64 bit, I have never gotten any UTVideo to work after version 6.1.

Ah ok, mixed something up there then.

Don't know how you could track the error down.
Does it show up if you simply overwrite the utvideo.dll with the 6.1 version? Extract the files from the installer with this:
msiexec /a c:\utvideo-7.1.1-x64.msi /qb TARGETDIR=c:\out

Try absolute paths in the registry to link the vidc.ul* to the dll, somewhere outside the system folders.
Or you could use Process Monitor (http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx) to check if VirtualDub even touches the dll.
To rule out your specific configuration of Windows 7 you'd have to reinstall Windows on a second hard disk and test again. Or in a Virtual Machine, that's easier.

I only have a 32-bit version of Windows 7 running in a VM, all I can say is "it works there". :/

JoeH

1st May 2010, 07:43

I fixed it! Thanks for your help, Boolsheet, I never would have figured it out otherwise.

All the registry talk gave me the idea of searching through the registry to see where else utvideo.dll appeared. There were some other registry keys that were messed up - I'm not yet sure if from previous installs or from an error in the current installer - that were preventing Windows 64-bit from finding the codecs.

Here are the changes I made to enable the 32 and 64 bit versions:

Fixing this key enabled UTVideo 32 bit:
HKEY_USERS\S-1-5-21-445962267-61098652-3305859534-1000\Software\Microsoft\Windows NT\CurrentVersion\Drivers32
(the keys in this registry were set to the old "program files" directories; once I updated them the 32 bit versions appeared).

This key enabled UTVideo 64 bit:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Installer\Userdata\S-1-5-18\Components\641C5E112721E173C1CAE65BB3935D9B
Key: BB418FCA7B304794A947F5C82578888A
(this key was set to "C?\Windows" (etc.) instead of to "C:\Windows" (etc.). Once I changed the ? to : it worked.

Now, one more comment - I have never touched the registry as regards UTVideo before, so these changes, or lack of changes, were almost certainly all done by UTVideo's different installers (I've installed and uninstalled just about every version). So, it might be worthwhile to update the installers to fix these bugs if they are still present, or to remove them if left over on some computer from previous installs.

If someone could make sure the developer of UTVideo knows about this, that would be great - I know some of you are in contact with him. Thanks!

JoeH

1st May 2010, 09:11

It just happens I had to install a Windows 7 - 64 bit Enterprise in English this morning. I installed the latest version of UTVideo 7.1.1 64-bit and both the 32 and 64 bit codecs showed up just fine. So, I image my problem was related to a previous version of UTVideo causing conflict.

Leeloo Minaï

1st May 2010, 15:44

Damn, i come too late with my latest INF script :devil:

Good news for you, you finally got to resolve your install problem !
Surprisingly, the registry key you mention does not appear anywhere with official installer or in my INF scripts... certainly an old entry from a 5.xx or 6.xx release.

I promised i will continue to update a far simpler INF installation script, here is the new one for release 7.11 :
http://www.megaupload.com/?d=L0F8JWW5

It is designed for NT systems only (32/64 bits), i didn't put Win9x support, i don't think it will suffer to anyone. :p

Very happy that the author is supporting UT as a DirectShow (or DMO as he calls it) codec!

Just one problem: the DirectShow components do not support the encoding options as a property page. It seems we can only change them via the VFW component. This is a bit of a pain.

Can encoder properties be added to 8.0.1? And please can encoder settings be retained in registry so we don't need to change them with every session?

Just one problem: the DirectShow components do not support the encoding options as a property page. It seems we can only change them via the VFW component. This is a bit of a pain.

A new post was written in Umezawa's blog two days ago.
I think that it is answer to your question.
http://umezawa.dyndns.info/wordpress/?p=1860

Reasons for UtVideo8.0.0 to use not ISpecifyPropertyPage/IPropertyPage interface but IAMVfwCompressDialogs interface are...

1.It takes serious time to mount ISpecifyPropertyPage/IPropertyPage interface.
　I think that a great internal change is necessary because UtVideo is originally made as VCM codec.
2.It was considerably easy for me to mount IAMVfwCompressDialogs interface on UtVideo.
3.The DirectShow capture software that I am using now can use only the IAMVfwCompressDialogs interface.

I want to mount ISpecifyPropertyPage/IPropertyPage interface on UtVideo. However, I can't get a good design yet.

Zarxrax

26th July 2010, 02:24

The vfw codecs don't save the settings. Is it supposed to?
I have to change the compression mode every time I use it.
The fast mode seems barely any faster than the high compression mode, but you can save quite some filesize with the high compression mode. So I don't see much reason to default to the high speed mode.

Edit: oops, I guess that was just mentioned 2 posts above :p

JoeH

27th July 2010, 07:43

I personally much prefer the high speed mode, as I notice a healthy speed up (maybe 10-20% if I remember correctly) when encoding to X264 through Sony Vegas.

New features
* Encoder is now able to save configuration globally by encoder itself.
* Encoder is now able to ignore setting of cofiguration from codec client (e.g. editing software).

NOTE:
If you want to use these new features, check the checkbox that exists in "Global Configuation (start menu -> UtVideo codec suit -> Global Configuation)" beforehand.
When both are checked, the behavior of codec becomes like huffyuv,etc.

This will invite making to low speed oppositely in CPU whose size of L1-cache is smaller than that of 16KB(e.g. Northwood).

First time I read about this codec. Seems really interesting, but the help says it only supports limited range YV12. Because avisynth outputs full-range, when using this codec for an intermediate file, quality will be lost :(

Anyways, I will be able to use it for Vegas temporal renders, because that's RGB. So thank a lot.

I just tested it and YV12 [0-255] input = YV12 [0-255] output

Perhaps the documentation is old, or what it is saying is if you allow UT to do the RGB=>YV12 conversion (instead of doing it yourself e.g. through avisynth, the range is limited (ie. it uses Rec.601 matrix)
