bbMPEG - Version 1.22 bbMPEG and AVI2MPG2 are Windows programs that convert AVI files to MPEG-2 or MPEG-1 (including VideoCD and SuperVCD) files. The file bbMPEG.DLL is also a compiler/export plug-in for ADOBE Premiere 5.0 or higher (it will not work with version 4.2). The file AVI2MPG2.EXE is a front-end for bbMPEG.DLL so it can be used without ADOBE Premiere. The software generates MPEG-2 (ISO/IEC 13818-2) or MPEG-1 (ISO/IEC 11172-2) video streams, MPEG-1 (ISO/IEC 11172-3, layer 1 and 2 only) audio streams and MPEG-2 (ISO/IEC 13818-1) or MPEG-1 (ISO/IEC 11172-1) program streams (including VideoCD and SuperVCD compliant streams) or almost any combination of the above. You can just do multiplexing if you want to, you don't have to encode video or audio. It can also multiplex AC3 audio streams into an MPEG-2 program stream.
