I've used TIFF sequences in the past, but they're not convenient because they're not user-friendly for novice editors, they don't include frame-rate information, and need to be zipped and unzipped for transfer (which is yet another area in which Macs and Windows need assistance in working together). I'd love to see Adobe provide a new default 'Lossless with Alpha' render setting, but while I'm waiting for that I need some new settings. I create a lot of animations that I send to Premiere editors on both Windows and Mac. These systems come fully configured, pre-loaded with the latest version of MediaShout (site license included), and ready to plug-n-play. MediaShout takes away the guesswork with computer bundles custom-built for church presentations.

I'm a motion graphics artist, but I'm not a technical guy. Worship software runs best on computers designed for media presentations. That is, it uses the 'Animation' codec which is a quicktime codec no longer supported by Apple. Renders encoded using After Effects' default 'Lossless with Alpha' settings can no longer be imported into Premiere (or any other program) on a Mac. Correct me if I'm wrong, but from what I understand:
