What is KVCD?
"K Video Compression Dynamics"

KVCD is a modification to the standard MPEG-1 and MPEG-2 GOP structure and Quantization Matrix. It enables you to create over 120 minutes of near DVD quality video, depending on your material, on a single 80 minute CD-R/CD-RW. We have published these specifications as KVCDx3, our official resolution, which produce 528x480 (NTSC) and 528x576 (PAL) MPEG-1 variable bit rate video, from 64Kbps to 3,000Kbps. Using a resolution of 352x240 (NTSC) or 352x288 (PAL), it's possible to encode video up to ~360 minutes of near VCD quality on a single 80 minute CD-R. The mpeg files created will play back in most modern standalone DVD players. You must burn the KVCD MPEG files as non-standard VCD or non-standard SVCD (depends on your player) with Nero or VCDEasy.

Using KVCD parameters to create DVDs (KDVD), will enable you to create 100% DVD compliant MPEG-2 streams, capable of playing on any standard DVD player. This will allow you to put up to about 6 hours Full D-1 720x480 on one DVD, or about 10 hours at Half D-1 352x480.

CQMatic and CalcuMatic now Open Source! - by Kwag 12/09/2006 @ 08:50

Hello everyone,

It's my pleasure to announce the availability of CQMatic and CalcuMatic as Open Source software Smile
As I don't have time (at this moment) to maintain and expand the programs, I decided to release them to the world so anyone may enhance and expand them.
You need "PureBasic" version 3.x to compile. Visit http://www.purebasic.com for more information.
The license model I chose, is the new and standard "3-clause" BSD style: http://en.wikipedia.org/wiki/BSD_license
This basically permits it's use in any commercial or private programs, and the only requirements is that the copyright notice is maintained on the sources that are released, and any binary release must also attach the notice to any documentation and/or other materials provided with the distribution.
You can read the license text on the program sources.
IP (Intelectual Property) code is not required to be released by any developer who would like to modify the sources and create new versions, unlike the GPL !!*viral*!! effect, which forces every programmer to release every drop of code they create.
So, here you have it Exclamation

CQMatic Sources: http://www.kvcd.net/downloads/CQMatic-1.4.08_src.zip
CalcuMatic Sources : http://www.kvcd.net/downloads/CalcuMatic-1.1.16_src.zip

Have fun, and excuse some of the sloppy code Exclamation Embarassed
Remember that these programs were basically "cooked" overnight, so functionality was selected before code dressing, so feel free to "Dress-it-up" if you like Cool

480x480
528x480
544x480
704x480
704x480 - long GOP (24)
720x480
528x480 - 16:9
544x480 - 16:9
704x480 - 16:9
720x480 - 16:9

Want a cheap and superb satellite TV receiver?

Get hold of "dvbdream" (free!) and get a cheap Twinhan DVB-S card (~$­­75.00) and enjoy satellite television (and you can also record to HDD and later compress to KVCD/KDVD ;) )
