My guess is you never used this, (any?) camera before. What worked good for some guy with particular sharpness and gain would not necessarily work the same way for you. If you don’t understand how to use it and in what circumstances simply stick to default mode.
Yes, in fcp capture footage as HDV, drag and drop it time line and conform sequence to clip settings. After you’re done with editing change sequence settings (command 0): change compressor to ProRes and export your movie.
