ReMPEG2

ReMPEG2 is a reliable and easy-to-use program designed to transcode an MPEG-2 video file to half D1 resolution (352x480 for NTSC, 352x576 for PAL) or SVCD resolution (480x480 for NTSC, 480x576 for PAL). Alternatively, it can keep the resolution and just lower the bitrate.

There are several scenarios in which this might be useful. (no need to mention a special one...)

Until now the original MPEG-2 video file had to be decoded into an AVI file (or similar) in the first step and then reencoded to MPEG

ReMPEG2 is a combined decoder/encoder which avoids these problems by preserving the sequence of picture types (IPB) and trying to follow the original stream's bitrate flow. This means that the user can choose a bitrate scaling factor which is used to calculate the number of bits available for each encoded picture from the number of bits in the corresponding input picture.

To transcode a file, open up ReMPEG2, press the "Open" button and select the input file. Only elementary MPEG-2 video streams and VOB files containing such a stream are supported at the moment. If the input stream is spread over several files you can make a file list and open it in ReMPEG2. Take a look at SAMPLE.CFFL...

After ReMPEG2 has analyzed the file (this may take a while only the first time since an info file is generated containing all necessary information for further runs), the "Main" tab contains some information including the bitrate of the input file. All that needs to be done now is choosing an appropriate output bitrate in the "Options" tab by adjusting the first slider.

Requirements:

￭ Pentium processor or better (support for MMX instructions is needed) ￭ 96MB of RAM or more are recommended. Due to some optimizations, ReMPEG2 has become a real memory eater. ￭ Screen resolution of 640x480 or better
