That video goes back a few years and I think I was using Sony DV cameras at that time.
Now I use Sanyo Xacti cameras with 720 definition.
One is capable of higher full HD but it is very slow in processing the files on the computer and doesnt make too much diference in the end video.
Models:-
1 x VPC-FH1 (full HD), and 2 x VPC-TH1.
both very simple to use with SD cards these days of course.
