Hello, I have a question I hope someone can help out with. I'm running Snow Leopard (10.6.8), and iPhoto 9.2.3. Currently my iPhoto library is 310 GB, and my boyfriend recommended I re-encode my hundreds of AVI and MOV files to H.264 to save space. We calculated about 140 GB in potential savings. The biggest concern before creating a batch operation to re-encode and replace all of the files is that the filenames would change from AVI or MOV to MP4. This would probably break the database. Any ideas or advice on how to go about this?
