Pro Maintenance Tools from Digital Rebellion can help maintain, optimize and troubleshoot Premiere Pro, Avid Media Composer, Final Cut Pro X and and Final Cut Pro 7
So I have talked about Digital Rebellion before and Post Haste and Preference Manager, but they have 2 packages of programs to repair and I have been a user of Pro Maintenance Tools since Final Cut Pro 7.0.
This suite of tools has a tool to Analyze Crashes, Repair Corrupt Files in a project (or at least help you see which ones are corrupt), Look up error messages, Manage Plugins, Schedule clearing of caches and preferences and a plug in installer.
It has a huge amount of tools (though of course Post Haste and Preference Manager are free), and most you don’t need until you do. This has saved me on a few projects where some media got corrupted, so it is a great tool to have around just in case, or to get in an emergency.
Corrupt Clip Finder also has often shown me bad JPEG’s, though I have had the problems a lot less since I stopped using JPEG’s due to corruption issues.
If you are having issues the $129 is quite worth the price of admission.
