Encoding Quality Samples

KVCD is a modification of the standard MPEG-1 and MPEG-2 GOP structure and quantization matrix. It enables you to compress more than 120 minutes of decent quality video (depending on your material) on a single 80-minute CD-R. The extended KVCD x2 and x3 specs allow for up to 360 minutes on a single CD!

The same compression algorithms and visual tricks can be applied to the DVD-Video format, too! Using the KDVD encoding templates, you can create 100% DVD-compliant MPEG-2 video streams that will play on a normal DVD player. The KDVD specs allow for up to 10 hours of decent quality video on a single DVD-R or DVD+R (single-sided, 4.38GB single-layer burnable DVD).

Image quality is a very subjective topic. This page showcases some of the compression quality that can be achieved under optimal conditions, when using the KVCD or KDVD methods of MPEG-1 and MPEG-2 video encoding for optical media formats.

KDVD MPEG-2 Sample

This sample shows the quality you’ll get when fitting approximately two movies (4 to 5 hours) on a single 4.38GB (“4.7GB”) DVD-R or DVD+R. The sample was encoded with TMPGEnc using a minimum bitrate of 300kbps and a maximum bitrate of 9,800Kbps. It was encoded in CQ mode at a value of 75, at a resolution of 720480, full anamorphic, and using the KVCD notch matrix. No filters were used for this sample!

KVCD MPEG-1 Sample

These samples shows how the complete movie looks on a single 80-minute CD-R. The video encoder was TMPGEnc, using the KVCD Motion Adaptive (AviSynth) Optimal script, and and the KVCD Notch matrix. Note that these samples don’t have audio; these are video-only MPEG streams.
