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.

The main problem I have with KpMg is that it is very slow - to move from stage to stage it needs to run ffmpeg on the entire file (even for autodetecting meta-data and for preview frame), and that can take 10 minutes or more on my PC. So its nice that it is a wizard type application where I don't have to know up front what I do, but compared to avidemux (for example) I can complete what I'm doing and still learn everything I need by the time KmPg completes one stage.

Also, the main reason I would want to use such a program is to do batch encoding, which KmPg does not provide - again, avidemux offers jobs management which is a bother to setup, but at least it works.

Ok, I got the cause of the problem you describe. Some FFMPEG version seem to interpret the -t flag differently, causing it to decode the entire file.

Fixed in latest version.

Another update of KmPg2 has been released. Please send any bugs or suggestions to my e-mail address.

Happy encoding!

Are there any other tools that KmPg2 can use instead of the SMIL utils? I'm having a major problem compiling it under GCC 3.3.5. Just curious since I'd really like to be able to use KmPg2. Thanks.

I just uploaded the new rewrite which can also use FFMPEG to decode MiniDV.

The downside of using FFMPEG is that it cannot seek in video files.

Please ask your distribution to include a SMILUtils package.

Thank you very much! This works perfectly! As for the SMIL Utils well, I think the reason it's not available in Gentoo is due to the fact that is hasn't been updated to use a newer version of GCC in quite a while.

Do you have any plans to add H.264 to this application ?

As soon as the MPEG encoder from the MJPEGTools project supports it, sure...

You made so much DVD programms now, maybe you should make one big programm where all these programms are integrated. So you only have to start one and then you can choose what you want to do (extrac Musik, rip a DVD, ...) .

Well, Kommander is not very well suited for developing full-blown applications with menus, project management and so on.

Besides, I'm a fan of the "One App For One Task" approach. Combining everything into one big monster-app generally won't make things any simpler.

One thing that could be useful though, is some kind of project management that lets you store settings between uses.

I like the idea of a hand off capability to allow the apps to pick up where one left off.
I highly encourage you to do that.

Thank you for your series of great apps.

I agree. If you could additionally handle use cases like "make a DVD out of every video format supported by [backend programs] (e.g. avi, wmv, ...)" you would be The King Himself. The only thing I find kind of sad is that your programs are seperate ones and not integrated into K3b, where I think they would really belong (and you all know, DVD video support in K3b is _really bad_). But the very concept of Kommander applications doesn't fit into that very well, so there's no use in wishing, is it?

Just wait for KmPg2 version 2.0...

Well, that would require me to dive into full-blown C++ KDE/QT development. I'll stick to simple scripting for the moment. :)

The K3B developers are currently focussing on the Audio department of K3B, my guess is that the Video department will be next. We'll see what K3B 0.13 will bring...
