My Panasonic FZ72 takes good stills and is occasionally used for video clips. Alas, the "Photofun" program supplied has reduced me to screams of frustration in hours of attempts when it comes to doing what I want with these clips. I bought Windows Moviemaker2 for previous XP/Vista PCs, but it won't work on Windows 8, and I need a simple, cheap (because rarely used) editor to cope with AVCHD and MP4 (and other?) format files. I have most old PCadvisor discs (not Disc+)and would welcome advice on choice of program.
