Yes it will certainly work. Then you may be able to drag/drop those files into the video bars. Worst case, you may have to IMPORT those clips into Vegas 9. Just as a precaution, please ask him the video format he will have in the hard disk – AVCHD/M2TS, MPEG-2 etc.
Good luck.
NB: I normally shoot stage shows with my Sony HVR-Z5U camera. That can record in a HD tapes (65 mins/tape) cost $12.00 each. Since i am shooting from one spot, I also capture the entire show directly in a laptop’s hard drive using the firewire port of the camera. This way,
I get a complete backup. Another advantage is that, when I change the tape, the hard disk continues capturing non-stop. So there is less chance of any footage.
