MakeFilm TNG

The MakeFilm application was designed to join two AVIs (FM and LM) into one, using the best quality of both. Easy handling, accurate prediction of final size, suggestion bitrate for LM-AVI based on only the FM-AVI and fast processing (< 5 min).
System requirements:
You need the Visual C++ runtime libraries (MFC42.DLL-stuff). If you dont have them, get them somewhere else.
MPEG2AVI and MPEG2AVI GUI or Flask Mpeg to produce the DivX files. I suggest the first as you can batch-run it, all options are in one command-line and can therefore be copied for encoding the film with the same settings again, and it is the fastest MPEG-2 to DivX converter yet, but what you use depends on you.
BIG harddisks, since you need space for two AVI-files encoded in Fast- and Low-Motion (which will be about 2 x 650 MB) and another 650-700 MB for the final video.
Preferably, you should use TWO harddisks to speed things up to 40% and to save your read-write heads: one for the source and one for the destination files.
