Final Cut Pro 7 Unexpectedly Quits When Sequence is open! Please Help!

It is possible your project is corrupt.

Open a new project(different name) and copy everything from the old one into the new one and then close the old project. Rename the old seq in the new project and see if it opens.

Do you have any stills that are over 4000x4000 or not RGB?

But did you TRY deleting your preferences? Do you want me to point you to posts here where it DID solve the problem? It doesn't solve every problem but there's a reason it's the first troubleshooting step. DigitalRebellion's preference manager allows you to back up your preferences so you can restore them if the reset doesn't help.

Personally, it has solved problems on my system. as I said not every one, but it's a good place to start.

You could also have a corrupt piece of media. If deleting preferences or darbypsnm's idea doesn't work, post back and we'll walk thru the steps to find the problem.

If you have a corrupt piece of media, try this.

Before you launch fcp, disconnect any drives where media for this project resides. If by some chance, media resides on your startup drive (generally not recommended) move these files to another folder. Duplicate your fcp project file (for safety sake) and launch the duplicate project. You will get a notice that your media is offline. Do not reconnect at this time. Will the sequence open? If so, more than likely you have a piece of corrupt media.

Reconnect your media drives. Make sure they are available on the desktop. Now gradually reconnect the media til you find the problem clip. Sometimes just doing this process will shake things up enough and you'll be able to reconnect everything. If you need more specific directions, or something's not clear, post back.

sorry you've got a deadline. When you have time, there's lot's of ways to set up your system to avoid or at least minimize these kind of problems.

In the meantime, here are some excellent troubleshooting steps.

What format are you working in? What are your clip settings and your sequence settings? Are you using any 3rd party plugins?

Many times, fcp will allow you to work with problematic material for a while, so just because things were working yesterday, doesn't mean that there weren't problems inherent in your workflow.

Let us know if you solve the problem. Happy to help get things set up better when you get past your deadline.
