Versatile Encoder allows you to encode your own videos into good quality mpeg4 or h264. The input can be a sequence of files (as generated by blender), a file (if you want to recompress something) or a DVD/VCD (if you need to backup some movie).

This piece of software tries to guess good defaults and to help the user in his choices. It works at least under Windows and Linux, the coding platform is Linux.

It should work without a hassle under all BSD variants and probably under MacOSX too, report me if you get it working somewhere else.

KmPg2 is a very simple to use MPEG2 encoding wizard that allows the user to create high quality DVD compatible MPEG2 streams, without requiring any technical knowledge.
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.
At this moment KmPg2 accepts only one format of input video: Raw Sony DV video streams. This is the video format that most people use nowadays for high quality video processing and editing. Support for using AVI files for input is expected in future versions.
Main features:
- Produces DVD compliant MPEG2 streams
- 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
- Supports progressive and interlaced source material
- Support for removing overscan area
- 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

Javascript Search Aggregator allows you to perform all of your Web searches from one place.
You can create many categories of searches such as work and fun and customize search engines for your specific needs.
Javascript Search Aggregator remembers the last query and state of the tabs and works on any browser with JavaScript support.
Enhancements:
- Do not load last selected engine on first load

iPod Video Encoder is a command line tool for convenient encoding of video files for use on iPod video. iPod Video Encoder project uses the ffmpeg tool for the actual encoding.
It features recursive encoding of all files in a directory, and generating a podcast.xml file for convenient use in iTunes.
It can be used in a cron job that periodically checks directories for new files and encodes them without user intervention.
Main features:
- Encoding of single files
- Optional specification of a/v bitrates
- Recursively encode all files in a directory
- Generating a podcast.xml for convenient use in iTunes
Options:
--version show programs version number and exit
-h, --help show this help message and exit
-R, --recursive Process directories recusively
-f, --force Force re-encode existing iPod videos
-t, --test Only encode first 10 seconds, to produce test videos
-e EXTENSIONS, --extensions=EXTENSIONS
Comma separated list of input extensions. Default: avi
-i IPODEXT, --ipodext=IPODEXT
iPod extension. Default: .ipod.mp4
-b VIDEO_RATE, --video-rate=VIDEO_RATE
Video bit rate, in kbps (default: 1024)
-a AUDIO_RATE, --audio-rate=AUDIO_RATE
Audio bit rate, in kbps (128)
-W WIDTH, --width=WIDTH
Video width, in pixels (default: 320)
-H HEIGHT, --height=HEIGHT
Video height, in pixels (default: 240)
-P, --pretend Do not really encode, just print out the ffmpeg
commands which would be executed
-v, --verbose Enable verbose output
Podcast options:
-p, --podcast Generate a podcast.xml file for each directory.
--podcast-documentroot=PODCAST_DOCUMENTROOT
Podcast document root; eg. /var/data/Movies/
--podcast-baseurl=PODCAST_BASEURL
Podcast base URL; eg. http://localhost/
Enhancements:
- Only uses the -e option for processing directories.
- The default ipod extension is now _ipod.mp4 for Windows compatibility.
- The README file has been extended with information on the .ipod-encoder settings file.
- The program no longer crashes when HOME is not set on Windows.
- --width and --height parameters have been added.

Extend For JavaScript allows you to use traditional single-class inheritance in your JavaScript applications. Extend For JavaScript also gives you many advanced features such as runtime class modification, introspection, and change.
It is simple, and does not depend on any other library. It works well with Prototype, jQuery, or MochiKit.
Main features:
- Can be used as a drop-in replacement to the current Prototype Class.create function
- Flexible and reliable super-like functionality
- Rich class-meta information, such as the list of methods defined in class, and for each other method, a link to the class which declared it, and links to all subclasses.
- Dynamic reparenting, which allows to change an existing class parent class.
- Dynamic class change, when you want an object to change its class on the fly.
