bbMPEG.DLL, AVI2MPG2.EXE and AVI2MPG2_VFW Version 1.23. By Brent Beyeler. Released as freeware. Freely distributable. ABOUT bbMPEG and AVI2MPG2 are Windows programs that convert media files to MPEG files. They are freeware, and the source code is available although you will need Borland's C++ Builder 4.0 or higher and the ADOBE Premiere 5.x SDK to compile it as is. INSTALLATION To use the software WITH Adobe Premiere 5.x (will not work with version 4.2) copy the file bbMPEG.DLL to your Premiere 5.x plug-in directory and rename it bbMPEG.PRM. After doing this you should see it loaded when Premiere is started and it should be added as an output option. To use the software WITHOUT Adobe Premiere, just create a folder, copy all of the included files to it, set up a shortcut to point to AVI2MPG2.EXE or AVI2MPG2_VFW.EXE and run the shortcut. The file AVI2MPG2.EXE is basically a front end for the DLL so it can be used without having to have ADOBE Premiere. It just calls the DLL as Premiere would. AVI2MPG2.EXE uses DirectShow to access media files. AVI2MPG2_VFW.EXE is also included if you have problems with AVI2MPG2.EXE (see the help file) AVI2MPG2_VFW uses the older Video For Windows interface to access AVI file and it may not open newer AVI files. NOTE: Please delete all *.PAR and *.PRJ files created by previous versions of bbMPEG and AVI2MPG2 as they are not compatible with this version. This includes the DEFAULT.PAR file. REQUIREMENTS bbMPEG requires Win95, Win98 or WinNT. It may work with Win31 if Win32s is installed but I have not tried it. AVI2MPG2 also requires Microsoft's DirectShow to be installed. All programs require a Pentium processor. NOTES The speed of this software will vary greatly depending on the setting of the motion vector lengths. Generally, the more motion in the video the longer the lengths need to be to reduce artifacts. The maximum video resolution supported is 1920x1152 for MPEG-2 and 4095x4095 for MPEG-1 and the audio encoding only supports 16-bit samples sizes and either 32 Khz, 44.1 Khz or 48 Khz sample rates. The software generates MPEG-1 (ISO/IEC 11172-2) or MPEG-2 (ISO/IEC 13818-2) video streams, MPEG-1 (ISO/IEC 11172-3, layer 1 and 2 only) audio streams and MPEG-1 (ISO/IEC 11172-1) or MPEG-2 (ISO/IEC 13818-1) program streams or most combination of the above. The software can also just multiplex MPEG-1 or MPEG-2 program stream without doing any encoding. It can also multiplex AC3 audio streams into MPEG-2 program streams. CREDITS The video encoding was derived from MSSG (MPEG Software Simulation Group) MPEG-2 video codec, version 1.2. The audio encoding was derived from the MPEG/Audio Software Simulation Group's audio codec, version 4.0. The multiplexing was derived from Christoph Moar's MPLEX, version 1.1.
