Introducing MI - MPEG-Inspector

...a tool for DVD-Video experts!

If you are content to just drop a DVD into the player and use the navigation
structure via the menu to play the disk, and you do not care about the
technical details of how this is accomplished, then this new tool of ours is
not meant for you.

If you are a more advanced DVD user that is able to create DVDs from your
own footage or from material edited and authored by yourself, and have no
problems with the results achieved on the produced disks, then this new tool
of ours is also not meant for you.

If you are a person experiencing problems with some DVDs you created
yourself and are interested in discovering and tracing the origin of  the
problem, then our tool might be able to help you achieve your goal by
enabling you to investigate the quality of the MPEG compressed material
written on the disk.    
The DVD authoring process is quite technical, and requires the adherence to
fairly strict standards when considering parameters such as frame rate and
size in combination with the local TV color system (NTSC or PAL). Another
issue is the importance of keeping the audio and video streams in sync so
that there is no loss of synchronization between the video and audio on the
playback device (TV or monitor).

We believe that MI - MPEG-Inspector may be the answer to investigations
along these lines by enabling the user to view and analyze, in either
superficial or minute detail, all the relevant parameters involved in the
authoring of a successful DVD. Once a problem with the properties of a
specific parameter has been identified as the cause of a faulty DVD, steps
can then be taken to rectify the authoring process and to ensure the
production of only quality DVDs.

We have found that, while there are currently several software tools on the
market that claim to analyze mpeg streams, very few, if any, are able to
concisely present information on all relevant parameters involved in the
definition of a mpeg stream that conforms to the industry specifications.
Some  freely available analyzing tools only show partial views from a
predefined point of view. One tool shows the arrangement of the frames in
the stream and gives information about  bitrates and frame sizes, while
another tool gives information about the quantisation-level, and yet another
tool gives only global information about the video.
MI - MPEG-Inspector is a tool for analyzing MPEG files. Its usage can save
lost time because problems can be recognized and eliminated by oneself or
with the help of competent users in video forums.



The typical summary presented by one of the commercially available  tools
seen here does not enable one to determine the relevance of time when
looking at synchronization problems between the audio and video streams. 



Till now you would have not been able to analyze, in detail, all of the
relevant important mpeg stream parameters with a single tool, and that is
why we like to present MI - MPEG Inspector




MI offers information about MPEG files at a user-selectable detail level - from a very basic summary only, to a highly detailed bit level analysis of the file being analyzed.

Specific video information, e.g. the arrangement and size of the video-frames and the structure of the GOPs  represent the next step of detail level.
On this level one of the things you can do is to show the deviation between presentation-timestamps and standardized time in a diagram. This maybe helpful in the detection of critical scenes in the video.



This typical Details Level  information screen of MI offers the possibility
to show elements of the MPEG-stream and the arrangement of these elements
within the stream.
Additional information will be displayed for selected elements.

When conducting investigations on this level, knowledge and familiarity of
the structure of MPEG-streams (defined by ISO/IEC 13818 Part 1 and 2) is
recommended in order to make the information presented by MI useful.

Should you find yourself not so inclined as to get involved with the
technicalities, you can analyze the problem mpeg stream with MI, and then
use the built-in logging and reporting functions to transmit the relevant
important details to a more technical person for analysis. This person can
then import the MI reports you sent, and base analysis and conclusions on a
much smaller amount of data without him necessarily having access to the
mpeg stream himself - all by, for example, simply sending a small file via
e-mail. If you require more detailed information on the analysis data and
methods of presentation, please view

We offer a fully working and free trial version of MI - MPEG Inspector for
download The trial

The trial version is limited to the analysis of only the first 360 frames of the
source MPEG file under investigation. We would appreciate any feedback
should you decide to use the trial version, and a contact form is supplied
for your convenience at the top of this page.
Comments from other visitors to this site are available in our 
guest book
The commercial version of MI - MPEG-Inspector will be offered in the near
future, and will get posted here as soon as details are finalized.
