MI Export and reports


	One of the main aspects in developing MI was the support of users in sharing information in forums. Due to the size MPEG files aren't suitable for sending it by email or uploading it to web space, not even in the age of fast internet access via DSL or similar. The idea was to find easier dispatching formats and to find ways for exporting it by MI.

	MI's functions for exporting files and creating reports are integrated in menu Export.

Alle exported files are saved in the folder, the original video is located.
One exception is the Directory list. This report will be saved in the uppermost folder of the selected folder tree.
Reports will replace older ones with the same name without any request.
In the text files the individual fields are separated with the Tab character. For not re-interpreting numbers during import in e.g. Excel, all exported values will have a leading ' - character (single quote).


	All exported files will have the name of the video with trailing characters which will define the content of the text file. (e.g. GD = general data, GL GOP list, etc.)

Export / Index file
MI is able to reduce a MPEG file by skipping the real audio and video information, but saving the important header data to a MI indeX (MIX) file. By zipping the MIX file the essential information is stored in about 0.2 to 5% of the original MPEG file size, depending from it’s total size.

A MIX file contains the GOP and frame data of the source file (without the coded video and audio).
In addition it contains the information which is shown in Panel Details.
The selected range in panel Frames defines the amount of information. Is e.g. the frame range from frame 234 to 593 (360 frames) selected, the resulting MIX file contains exact the data of this part of the video for further analysis.
On the target system the MIX file can analysed fully for this range, but without decoding the frames or playing the video. The GOP structures and all frame related information are available. In Panel Details the same range can be analysed as shown on the original system.

	Export / General Data The data as shown in panel General will be saved in form of a report. These data e.g. can be fully or partially posted in a forum and can be important information for "helpers". TOP


	Export / GOP list The GOP list represents the GOP sequences of a complete MPEG file. Extracts of this list can be helpful for determining unusual parts of the video that may cause render hangs or compilation errors while producing a DVD.


	Export / Bitrates list An exported bitrate list, opened with e.g. MS Excel can produce a chart of bit rates reflecting the complete video file with a few mouse clicks. TOP

Export / Details list and Dump list producing reports with a very deep view into the internal structures of a MPEG file. For sharing information between experts these reports will a great help.
A report, produced with Details list doesn't contain the information of the full file, but only the filtered portion which is shown in panel Details. With this the user can determine the range of the report for his own demands.
The name of the details report contains the name of the MPEG file trailed with DLx-y, where x is the number of the first and y the number of the last frame in the report.
A report, created with Dump list, represents the range of the file shown in panel Dump.
It is an excerpt of the file with a size of 8KB, usually -4 KB to +4 KB around the header which was selected in panel Details. The name of the Dump report contains the start address of the dump.

		Export / Directory list This function expects a user selection of a "start" folder, e.g. the folder video_ts of a DVD structure. Starting at this folder, files and folders including sub-folders will be listed with name and size. In addition the report contains information concerning the drive and the accumulated file sizes.

	Export / Video Snippet Snippets are excerpts of a MPEG file containing interesting or problematic parts of a video. A snippet contains all relevant parts of the selected range of the source video. The range can be adjusted in panel Frames. (Zoom, Slider, Keys). The minimum range is less than 60 Frames, the maximum is less than 720 frames. The resulting size of a snippet demands on the content of the snippet. Example: A snippet of the first 56 frames of a MPEG rendered with 6,000 kbps (test video Pinnacle's Photoshoot) has a size of 1.8 MB. A snippet of the same test file, but 88 frames long results in 2.8 MB. A snippet start always with the first I frame of the first fully shown GOP in panel frames and ends with the last frame of the last fully shown GOP. The header data which are necessary for decoding the frames will be extracted and saved in the snippet. The same applies for the end of the video.. A snippet starting with the very first frame of a MPEG video contains all information leading the first frame in the file. A snippet ending with the last frame of a MPEG video contains all information which are trailing after the last frame in the file. No modifications of the contents will be done. Even the time stamps will not be modified. TOP
