So I am giving up on color-correcting Star Tours. That doesn't mean I don't think we should use it, but rather that I don't think I can fix it. I will make everything I've gathered available soon so someone else can try it. I did find the B-roll clip (this is it on YouTube) in better quality, and I believe it may be enough to suit our needs and slightly expand our footage, simply showing a couple of seconds from the Millennium Falcon's cockpit window cruising over the Death Star surface, as Ronster suggested. But if anyone wants to do anything further or preserve the whole thing, I will provide everything I have for your color-correcting pleasure...tomorrow, probably.
Also, Johannus was kind enough to gather items for the third and final vote for me. I will be arranging these soon and will post our third and final round very soon. Thanks so much for the help, Johannus!
