I didn’t bother with the software you can just pull the vids and photos straight off it as you would a flash drive then chop it up with windows movie maker or the like.
the vids are recorded in .mov style which is quicktime . Viewing the vids or pics with anything else will reduce quality greatly and sound will be affected.
I like to when I get home plug it into my TV with the hidef cable and check the footage looks great to me?
I would just install quicktime and set it as default programme for the vids and pics you see on the atc9k when it is pluged into your pc and it should be good.
