The episodes that you buy through iTunes are big: 640×360 and around 300MB each. That’s bigger than they need to be just for the iPhone’s 480×320, because they are also made to be watchable on your computer as well as your Apple TV. So what can you do to fit more on your iPhone or iPod touch?
Well, you could start off by using versions of the videos that are only 480×270. They’ll be smaller than the iTunes downloads, and yet they’ll still look great on your iPhone. Unfortunately you can’t just resize the iTunes videos you’ve paid for because they are restricted by DRM, but hopefully that will change sometime in the not-too-distant future.
For now, your options seem to be limited to either ripping them yourself from your DVD collection or downloading them from the various “other” locations on the Internet. Once you’ve converted your videos into iPhone-formatted files, you’ll be able to fit more episodes on your iPhone than with the larger-format ones … But there is still a limit to how many you can sync at any one time.
This, my friends, is where iVid comes in.
