Ok.. experimenting with a bit more complex editing techniques. 
 If current process does not allow 'pauses' between avi recording, I figured I can sort of go around that problem by picking the parts that need editing, split them up, and combine the files into a new film file so there's a bit of 'leftover/overlap' scenes between each joints so I have some plenty of time to move camera angles and positions, and cut the overlapping frames out later. 
 But the problem is, I CAN'T use the append function at all. After I add the parts together, and press the Append Films button, the program says 'Done'. But the program keeps giving out "Invalid or old format" message when I try to play it, and the 'newfilm.ahf' isn't saved. 
 Is it only me getting this problem? 
 Anybody succeed in using "Append Films" function?
