The interview videos could do with a bit of editing if it is going to be text based, Mr. Squirrelz made the same mistake, and now I have a few minutes wasted waiting for words to be typed on either end of the conversation. It may be 10-30 seconds each time you wait, but it adds up to minutes gone. Private chat could be turned off, and the screen cropped and enlarged with a resizing algorithm for the pixel increases. Afaik, focusing on a section of the game window can decrease CPU usage and allow to increase frame rate, if it matters.
Some of these tips I got from Excl's RS movie making tutorial, which he still hasn't reuploaded, and some are common sense.
