Background Info: I'm using an intel imac 2.66 GHz, Mac OS X Snow Leopard, iLife '09 I have made some videos of me playing Heavy Rain for youtube, and it is a four-part series. I got the footage from a DVD I recorded (my method of recording video games) and for some reason iMovie would let me export in HD after I edited the footage. It did that for the first three videos, but now the fourth video will only export in what iMovie calls "large". I've been using the same video file for all four parts. My question is: How can I export an iMovie 09 project in HD, without it actually being HD? It would be really annoying to see three HD videos on youtube, and then have the fourth one be SD.
