"Works wonderfully in the background"
Automatically converts files to whatever format they need to be in
Makes QT so much more useable
Must-have if you download a lot of videos from varied sources
None so far
Switching PAL files to NTSC would've been nice though, for Toast.
I was wracking my brain and wasted so much time trying to convert downloaded FLV files with other programs, just to be able to view them on my old PB G4. This add-on completely eliminates this need. Now I can just double-click on ANY file (with Flip4Mac for WMVs) and it opens and starts playing as if it were a native QT file. Tried dragging some odd files into Toast 9 to burn a DVD-Video, and it even automatically converted them for THAT, with no degradation whatsoever. AMAZING! It won't do anything to improve the quality of your files or convert between NTSC and PAL, but not only does it allow you to view them, in whatever format they're in, but it also opens up so many more options for HOW they're viewed.
Without Perian, I'd still be sitting here needlessly converting video files (which can take several hours on my slow G4--overnight with some files), and further degrading their quality in the process. This has "dumbed down" newfangled video files on my Mac to the point where even *I* can view any file with confidence!
