I know nothing about editing video files, and have tried a couple of videos with my 5DMkIII. I am using Photoshop CS6 (not the extended version) and LR4.1, and have been able to bring the .mov files into the Library module to view them in LR4, and into CS6. However, I can't seem to save the edited files as .mov or any other video file from CS6. The can only be saved, apparently, as Tiff files.
I am not going to get into video, but would simply like to shorten clips and possibly remove portions of clips, and maybe add a cross fade between 2 clips. Can PS CS6 do this? What about Premier Elements? I don't want to buy more software if I don't have to.
