MedianSoft Joiner-Converter allows you to merge, cut video clips and convert them (AVI, WMV, or MPEG) into different AVI and MPEG formats. In addition, the program lets you create video slideshows from your digital images with transition effects and accompanied by background audio.
You can merge the whole files or selected parts, even though they are in different formats. For example: you can use movies of your family, wedding or vacation, stored on your CD/HDD and combine them creatively into a single movie with funny transitions. Besides, any supported media files may be splitted into smaller pieces.

This program may be used with any codec installed on your system. Moreover, this provides you with preview before the conversion and lets you select the frame size and rate, set up NTSC or PAL for the output file.
