Hi,

the video has three parts and joined them with the tool moviejoiner.
Looks like this was best tool, the other joiners made even more complications. Now the movies is playing, but when one part is finished and the next begins, it stopps for just a moment and stutters. The videos when apart are ok. Tried it with different files like WMV files, Avi files and Mpeg files. The worst is with Mpeg files.
Is the problem the joiner? Do I need a filter, decoder, encoder or some kind of tool to fix the problem?
G-Spot says all necessary codecs are installed.

Thank you for every advice.

It won't be seemless unless all video parts are similiar in terms of audio, video compression, framerate etc.

I use VirtualDUb Mod to append similiar AVI segments and turn out seemless. You could trim/edit video portions using video editor like Adobe Premiere, but it would be tedious.

Should find many softwares that will join video clips 2gether.
