You can usually use their software for free for a while. Worth trying. Very lightweight but make sure you don't install the trials for other stuff you don't want
I'm trying to find a suitable video camera for capturing live video on a new PC (a consumer level one). Maybe using HDMI (but that'll take up loads of disk space). They don't have firewire any more :(
And doing Picture in Picture....
Any recommendations? Thanks.
