A:AnswerHi Dennis! You can record Dolby Digital 5.1ch surround sound with the built-in microphone (default
setting). Realistic sound can be enjoyed when playing a movie on devices that support 5.1ch
surround sound input. -Anthony
A:AnswerHi Chris, You may import movies and still images to a computer by connecting the camera using the supplied USB cable. The video recorded is in MPEG-4 AVC/H.264 format. -Jerome
A:AnswerI can't answer your question the way you probably would like. I love this camera but have had many sony camcorders for 20 years. I haven't had a battery issue because I have 2 batteries so one is always ready to go. just change them and recharge the one I take off. I have done this for years because when your traveling in places you won't go back to again you really want the video and pictures. Hope this helps
A:AnswerThere is a "star sky" setting or something like that which should work but I haven't tried it with fireworks yet.
Suspended below a drone would be amazing for fireworks. The camera automatically recognizes that it is upside down and corrects orientation for you.
