I am looking for an easy to use video editing software that can do the following :
1- The ability to add text to the movie as with the translated films.
2- The ability to extract the sound from the movie and save as an external wave file.
3- The ability to replace the current sound inside the film in
some parts of the movie.
4- The ability to add video effects such as : Slow motion of some part of the movie, pausing the movie for some time.
5- Deleting some scenes from the movie. For example deleting five seconds that contain adult material.
6- Adding scenes to movie at any part inside this movie.
Please advice for a powerful video editing software to handle these functionalities.
Thanks in advance
