Product Description:

Digigami MPressionist HD 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.

What's new in this version:

  • Primary functional improvement in this version is support for HD (Digital TV) streams that have changes in resolution. Such streams can now be analyzed appropriately and changes in frame size at sequence_header boundaries is transparent to the user.
  • New in this version is a complete Aqua-fication of the user interface.
  • Numerous bug fixes.

Operating System Requirements:

This product is designed to run on the following operating systems:

  • Mac OS X 10.3
  • Mac OS X 10.2

Additional Requirements:

  • Mac OS X 10.2.8 or higher

I've been using MPressionist HD since it came out. I've found it to be a key tool in my MPEG encoding workflow. I verify virtually every encode with MPressionist to be sure the peak bitrate and quality are what I expected. It's especially valuable for determining if the top_field_first flag is set correctly. I haven't found anything else that gives me the same information.

The developer is very responsive to suggestions and help requests.
