sending files back from color to fcp 7, but experiencing issues
I have four sequences in a FCP 7 project. I sent three of them to color from FCP 7, completed my grading, rendered and sent back to FCP 7. I did the same for the fourth sequence; however, when I opened this sequence in FCP 7 it had over written one of the other timelines media into the same clip lengths as the one I just sent back. So it had media from another project, but with the same clip lengths as the I had just sent back from color. I have never experienced this before. I am working for an advertising agency and I am basically getting raw footage ready so that it can be send to an animation house who is going to be adding their animations, transitions and exporting the project. This project is on a tight deadline and need to figure this issue out quickly. Is this indiciative of corrupt files somewhere? If any one has had this issue please share how you rectified it.
Thanks.
