Woop! Good news. I just installed FRAPS and gave it a quick test on my laptop. The previous youtube trailer was made on my super powerful desktop PC, but I was worried that my travelling laptop wouldn't be able to handle it. But all good baby. I can record at a perfectly smooth 1080p AND have the video saved directly to my external HDD. I was worried about that too as I have no spare space on my laptop. So we're good to go! The only catch is I have to record at 30fps, but that's alright.
I won't start making a video for another month or so because I want to release the 3D player and vehicle models first, but this is quite a relief. New video will be awesome. If anyone wants to help with storyboarding be my guest!
