Grab this filehttp://files.getdropbox.com/u/1349444/m ... joiner.rar
un rar it to where ever now copy the two files to a folder where you have a 2 part movie
1.Open Notepad (you can use any text editor, but I am going to assume Notepad).
2.Type/paste the commands you want to be in your batch file. In this case Type everything in the brackets but not the brackets
["joiner.bat" "filename a.avi" "filename 2.avi"] make sure you change filename a.avi and filename 2.avi to the actual filenames of you two part movie
3. Select File > Save As.
4.In the dialog, browse to the location where you want to save the batch file.
5.Change the “Save as type” option to “All Files (*.*)” and then enter the file name ending with “.bat”, for example: 2part.bat
6.Alternate to step 5, you can enter the file name “2part.bat” (including the quotes) and this will ignore the Save as type setting.
8 Then browse to the folder with explorer and run the 2part.bat and hey presto movies are joined
This will fail if both parts of the movie are not exactly the same ie same resolution codec etc
to do the next one copy mencoder.exe ,joiner.bat and 2part.bat to the next folder edit 2part bat with notepad and then run it again
hope this helps
