Description:

KmPg2 is a user friendly MPEG2 encoding wizard that enables the user to easily create high quality DVD compatible MPEG2 streams from any input video file.

Creating high quality MPEG2 streams involves a lot more than simply feeding the input video to mpeg2enc/transcode/mencoder/etc. The input video needs to be carefully prepared by pulling it through a chain of stream processing tools like low-pass filters, color correction filters, static and dynamic chroma and luma noise filters, scalers, and so on. This processing chain needs to be tuned in such a way that all irrelevant data (like noise) is removed before the video enters the encoder. KmPg2 uses the video processing / encoding tools from the MJPEGTools project to achieve this.

KmPg2 features a 'profiler' that enables the user to interactively create custom pre-processing pipelines that are optimised for a specific type of video material. These preprocessing pipelines (profiles) can be stored and used with the actual encoding wizard. For example, you could create a profile that is designed especially for restoring a single aging VHS tape, or you could create a profile tuned for your digital camcorder and re-use it for every new recording that needs to be encoded.


Features:

* Produces 100% DVD compatible MPEG2 streams from (almost) *any* input video
* Copy full surround AC3 soundtrack from AVI to MPEG2
* Supports adding subtitles
* High output quality by using MJPEGTools filters
* Create and store custom image processing presets
* Will use multiple CPUs when available
* Automatic conversion between NTSC and PAL formats
* Seperate chroma/luma noise filtering
* Low-Pass filtering support
* Contrast/Brightness/Saturation correction
* White balance correction
* Special black-and-white mode
* Crop image to Widescreen (16:9) or Panavision (2.35:1)
* Output conforms to Rec.601 specifications
* Both constant bitrate and variable bitrate encoding
* Unsharp masking
* Correct treatment of both progressive and interlaced input video
* Support for removing overscan areas
* Provides feedback to user about average/peak bitrates
* Show output on screen while encoding
* Generate encoding shell scripts
* Generate quick preview-encodings of parts of source video

Requirements:

* Kommander >= 1.0 (part of kdewebdev >= 3.3.0)
* FFMPEG
* Transcode
* Sox
* MJPEG Tools >= 1.8.0
* y4mscaler

Optional:

* SMIL Utils (for seeking in MiniDV recordings)

How to install:

Simply unpack the archive and run the 'Installer.kmdr' Kommander script. That's all.

I've got Archlinux.. I've installed all dependecies and the program starts. But when i choose the file to convertert, an alert says that my ffmpeg version can not decode Ac3 format who is necessary to DVD.. Why this?
I go to the shell and type:

ffmpeg -formats

And I can find in the output

ffmpeg -formats | grep ac3

DE ac3 raw ac3
DEA ac3

My version of ffmpeg is compiled from svn I think (but it's in the arch repository).. Maybe this is the problem?

Also I compiled ffmpeg with liba52 support
but kmpg2 keeps saying that cannot continue because cannot write AC3 sound.

What config params. should be used at ffmpeg compilation time ?

It seems there is a bug that prevent kmpg2 to recognize ac3 in ffmpeg. Got the same with Mandriva 2008.
I found a way out. In YUVdecoder.sh, in the TestAudioEncoding, you must change the value -ab 384 in -ab 384000 and reinstall kmpg2 to pass the ac3 test. FFmpeg cant encode ac3 with a value like 384 b/s, only with value like 384 kb/s.

But i get an error encoding video (**ERROR: [mpeg2enc] Could not read YUV4MPEG2 header: system error (failed read/write)!). Don't know if this is another bug or a sequel of my change in YUVdecoder.sh

Forget to tell that you have to change also the Audiobtirate in YUVMultiplexer.sh to 384000 in order encoding to work.

My error came from a different version of Y4mscaler and mjpegtools. i recompiled Y4mscaler with the new header and all went fine. so, all is working fine now.
And good new, the "cheat" -ab 384000 works fine. so enjoy this great tool.

Getting error "You don't have the utility "y4mscaler" installed!" But it is installed. What do I have to do so that KmPg2 can find it?

Yes I read the "read ME =" and the "install" documents, But they are, at best, confusing.

The command:

y4mscaler -h

should give you usage hints for y4mscaler. It this does not happen, the application is not installed correctly. Please ask your distributor.

is it possible to encode hd movies without scaling them to 576p?
Will this be possible in future? it would be amazing!!!!
Please!! :)

Hi,

good work. I'm using your excellent tool since months on a AMD64 Debian Etch system and I'm desperately waiting for a new version which supports mencoder as well as ffmpeg ???

Cheers

This is some good stuff for movies!
Not so great for a series though. Could you add:

File lists
projected finished size

So those of us who try to sqeeze a whole season of 1/2 hour video could do it with ease?

Thanks

As far as I know, DVDAuthor does not support colorful subtitles. You will have to live with plain white for now.

The issues with distributions using the CVS version of FFMPEG have been resolved.

KmPg2 should now work for everyone, hopefully. :)

Well, either you own a machine that is not suitable for video processing, or you have a configuration problem.

Personally, I run a 800 MHz Athlon machine, and it never takes more than 10 seconds after pressing 'Play Preview' before it is actually playing.

About batch processing: You can have KmPg2 write a script in stead of execute the encoding right away. This is a BASH script that you can submit to any job scheduler. You can even concatenate multiple scripts into one, if you want.
