MPressionist HDTV for Mac

From Digigami:

Digigami MPressionist HDTV is an all-new version of Digigami's premiere MPEG video diagnostic tool. The new version has been extensively optimized for the G4 and G5 processors using the Velocity Engine. The tool gives the broadcast engineer complete access to the video bitstreams in MPEG-2 Transport or Program streams, with built-in demultiplexing features that can extract individual elementary streams from multi-program system multiplex files captured live or directly from encoder sources. MPressionist HD provides access to all sequence, group_of_pictures, and picture layer header values, allowing the engineer to check time code, determine if flags are set correctly and generally double-check bitstream requirements. Works with all DTV video formats, including 1920x1080i, 1280x720p, 704x480i, 720x480p, 720x576i etc. Graphics overlays are superimposed over the moving picture, providing access to both stream-level and picture-level statistics and compression values. Correlate bitrate fluctuations with compression changes.
