Hello, Maybe I'm trying to do the impossible using Avidemux and Win 7 64. I'd like to be able to add a video segment to the middle of an existing one. I see that I can ' append ' the file but that just puts my added segment at either end of the video. All other features of the program seem to work fine, I can deleted segments, or copy them and save them. Is it possible to use Avidemux for such a thing or must I use something else with more features? I am new to video editing, the answer might be obvious to those more experienced, but I'm stuck! Thanks to all in advance!
