SolveigMM MPEG2 Requantizer Component is an engine designed for a fast and high-quality recompression of MPEG-2 high bitrates video. The component has been 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 the set compression ratio and writes audio/video streams to respective files. Audio streams are dumped as is, without recompression.

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