MPEG-2 fast and high quality recompression

04-23-2005, 05:55 AM
SolveigMM MPEG2 Requantizer Component is an engine designed for a fast and quality recompression of MPEG-2 high bitrates video.
The component was implemented as DirectShow filter.One of its main purposes is a fast DVD back up.

The demo application inputs are MPEG-2 Video Elementary Stream, MPEG-2 Program Stream, DVD VOB files.
It splits video/audio streams, recompresses MPEG-2 VES in concordance with set compression ratio (picture 1) and writes audio/video streams to respective files.
Audio streams are dumped as is, without recompression.

Total audio/video files size is approximate size MPEG-2 or VOB of file containing these streams after multiplexing.
Such one can estimate potential VOB size decrease.

Can it handle High Def?

Sure the requantizer operates with HD MPEG-2 properly.

New version 1.1 is available

It accepts advanced parameters:
- a unique compression rate for each picture type I,P,B
- amount of macroblock DCT coefficients to be discarded
