What are you using to edit it?
Windows Movie Maker.
It crashed earlier then restarted, but made all the files I put in it blank/corrupt.
So instead of jamming a stuffload of 1GB videos into such an unreliable video editor, I'm going to limit 4 per project.
I usually pause the recording at the ingame menu to look at a few things (steam chats, forums, etc.). I then resume when I'm done.
Also, change of plans. I will instead be recording myself playing the Homeworld 2 Campaign.
I haven't made it past level 3 yet because I'm lazy.
