UT VIDEO editing and playback

[netquik]

Hi all... I'm capturing using UT VIDEO ULY2


is there any way to playback , edit and authoring this type of video before encoding?


i read this on last VLC changelog:
* Support for CDXL, Ut Video, VBLE, Dxtory codecs via libavcodec.but don't know if it is useful
Thanks

depends on your editor. make a test video and try it.

Edit and encode first. Author last. Whether your desired output is SD DVD or HD, you can't author if the vid isn't encoded properly for the desired format. DVD, BD and AVCHD are YV12 colorspace; they can't be anything else.

thanks guys... the problem is that no app can "read" ut video files

actually i need only to cut parts of captured videos before encoding

[sanlyn]

VirtualDub can't open this UT Video file?

Avisynth can't open it with AviSource(), or ffVideoSource(), etc.?

If you have the de-coder installed in your system, a player like MPC-BE should be able to at least display it.

But we're guessing. Get the free MediaInfo utility, open the UT video with it and export MediaInfo's report as a text file, then post it here. Otherwise, we don't have the slightest idea what you're talking about except that you have some kind of video file that's compressed with UT Video Codec.

Maybe you need to update your codec. The newest version of the codec includes VCM/VFW, DMO, MFT & QT (though QT doesn't fully support all the colorspaces of the others). That's encoder & decoder. So you shouldn't be having trouble, as that pretty much covers most of the bases, unless you are using an editing system that uses it's own codec suite/infrastructure.

Yup, once again: MediaInfo!

this is Medianfo
btw i manage to playback it with WMP .. also in generic system


can' figure out how to decode it in VLC or AVIDEMUX


GSPOT says it can be decoded like this:


AVISPLITTER -> VFW:UtVideo YUV 422 BT.601 (ULY2) VCM - Video Renderer


can i force VLC to use this chain?


thanks

It says "via libavcodec".

Libavcodec is an open source binary codec library. It's pretty good but it is not specific to vlc. It's actually part of the ffmpeg project. A number of good open source media programs use it. Like avidemux, though I admit I don't use libavcodec in avidemux myself.

I suspect any good ffmpeg based program should also handle ut files.

BTW, if WMP will play ut files, I suspect that may be because you have a 3rd party codec pack installed. Which is not the same as having libavcodec included with vlc etc. Friggin' WMP won't even play flac files without one of those stupid codec packs ...

[Cornucopia]

Since VLC uses libavcodec for utvideo, and since libavcodec uses ffmpeg architecture, just (uninstall & re-)install new version of ffmpeg, and then make sure in the ffmpeg filter configuration that libavcodec is used/turned-on/defaulted to.

@HoserRob, I completely agree about the need for avoiding codec packs, however, it's quite easy to get WMP (and any other simple directshow-supported player app) to accept flac (without the need to resort to getting a codec pack). The FLAC site itself specifically mentions & provides for WMP/Directshow plugins.

@Cornucopia, I tried but VLC seems not using FFMpeg for that decoding... and syas it can't playbacl ULRA filesi will try again


i use shark007 win7codecs on my machine and for AVI is already set to use FFMpeg and libavcodec

[infinite.loop]

Basically every DirectShow based software is able to edit/play the recorded UT Video files.

I am using Adobe Premiere, but i.e. Sony Vegas works with these files just fine as well - if you install the codec.

[Cornucopia]

Just so you understand: VfW/VCM, Directshow, Quicktime are all underlying architectures or 'ENGINES' for running multimedia. Those are all system-wide.
While it can be configured to be commonly used by MANY apps, ffmpeg (an application and an 'ENGINE SHIM') is NOT system-wide - apps that call it may call different versions (from various locations, and with varying degrees of utility & bugginess).

Also, win7codecs may install a LOT of things (probably too many), but it still relies primarily on ffmpeg (which may be one of the reasons it is less invasive & upsetting than some of those other codec packs). As has already been previously stated, you need to get the DIRECTSHOW (or other engine)-appropriate codec plugins directly from UTvideo site. And do NOT get another codec pack - all you need right now is this ONE codec, and you would gum up the troubleshooting by adding in other complicating variables.

[netquik]

yeah i know that... thanks

btw some apps seem not very kind to customization when they have to speak codecs...
looking for a way to have VLc and AVIdemux work with UT Video files...

[Cornucopia]

Well, one of vlc's strengths (or weaknesses, depending on your situation) is the fact that its use of codecs is fully "self-contained".

There are lots of apps. Don't be tied to one if it doesn't work for your needs.

[netquik]

thanks... yes you are right... any suggestion for a "free" tool that let me cut parts of an UT Video file? (i used to use avidemux)

[smrpix]

Try virtualdub as Sanlyn suggested earlier. Doesn't get much easier or freer. (okay, if you like it, donate.)
