Importing and Batch Renaming

When shooting a video project with a lot of video files, particularly weddings, what process do you use to import and batch rename your video files?
Sync cameras times, Adobe Bridge, file structure, etc.

I don't bother renaming files but try to ensure all media , including music, animations, titling etc. is all in one directory exclusive to the project. I may then move, or import, elements into sub directories of that directory. This ensures all the media is together and can be easily backed up. Also, if the project file goes pear shaped you know where everything is.

Vegas has a great facility with Media Bins this allows you to arrange different clips into different categories without worrying about renaming.

I ran into an issue once where two cameras were using the same file names/number sequence and the footage got mixed up when I had to re-link the media in premiere. I figure if I can find a solution to rename all of the files from multiple cameras from a single job, I will avoid this happening again in the future.

I believe adobe bridge will do it.

I do not rename files. I do not want to CHANGE the files or the file structure in any way. I import the top directory folder from the camera/card and rename it (just the top folder) according to the project. If I have six cameras and three recorders, I'll have nine folders total. Easy to organize and easy to import.

I use ACDSee for batch renaming even if it's not media related files it have great built-in tool.
