Did this ever get resolved? I’m also seeming to lose render info when I leave and return to a sequence. I’m using FC7 on a MacPro, I’m working with a DVCPro HD sequence, in unlimited mode. I render some different format footage with Pro Res that is “orange”. I save. And when I go to another sequence or project and return to the rendered sequence, the “orange” is back. Any suggestions would be greatly appreciated.
