To create new proxy files, for a whole drive, it only takes about 30 seconds to a minute.
Here are the basic steps:
1. Import all files
2. Select "No Resolution Ext (_F,_H,_M,_P) under the QT Wrappers - Options menu
3. Change Destination folder under QT Wrappers - Destination Folder to Output Folder
4. Under Output, select folder to output proxy files to. I would suggest naming the folder with the type of proxy file that will be in it.
5. Now under QT Wrappers, choose the type of proxy file that you want to export. Don't choose make all wrappers.
6. From there, you can create another set of proxy files at a different resolution. Because each set will have the same name, you can you FCP reconnect media to force connect to the different resolution. Then if you change your sequence settings to match the new resolution, you should be in good shape. You can also reconnect to the new Log & Transfer files if you have them around.
There are a lot of options.
