MPressionst 3.0
Digigami today announced it is now shipping , with new tools for both high and standard definition MPEG, statistical and comparative picture quality, and bitstream analysis. Used by scientists working in the field of image and video compression, the frame-difference analysis features of make a "more reliable and scientific approach to DVD picture quality possible." The latest version makes finding compression artifacts easier. A new 'picture difference' or 'delta' feature, allows the DVD author to 'watch' the compressed movie as per-pixel differences from the original source material. In addition to 'per-pixel difference/delta' analysis, the comparative features of version 3.0 also includes side-by-side split monitor analysis for comparing the actual moving picture.
Users can also bring up two different compressed movies and perform a subjective left/right comparision by watching (in sync). Such a feature is "remarkably useful for determining if compressing a movie with a reduced bitrate has significantly impacted picture quality." Users can even compare movies compressed with different codecs (such as HD-DVD H.264 and MPEG-2).
"MPressionist Pro HD also includes metering and monitoring tools useful for finding common technical problems inherent in DVD authoring and production." An 'interlaced' playback mode, which can be combined with slow motion playback, makes it very easy to visually determine whether or not the field dominance of the compressed MPEG movie accurately reflects the field ordering in the source movie.
MPressionist "meets the expectations of consumers whose notion of quality has been shaped by Hollywood feature films."
"Although we design MPressionist to work with MegaPEG (Digigami's own compression software)," continued Digigami CTO, Gen Kiyooka, "since MPressionist conforms to the ISO/IEC 13818 and 11172 MPEG standards, the software works with all kinds of MPEG encoders and applications of MPEG-1 and MPEG-2 video.
The 3.0 version of MPressionist.X Pro is available now in two configurations, starting at $240.
