So you are going to be playing it back on an HDTV using an Apple TV or something?
Shake is the way to go if you want to upconvert. I’m a little rusty with it and don’t have the time to dig in right now. It’s not exactly user friendly either. You could try After Effects first to see if you like the results. It’s easier to use.
The “old” SD DVD Hollywood titles look better than your DV 4:1:1 timeline compressed to DVD using preset setting in Compressor because they really know what they’re doing and have the tools to do it. And did I mention that they didn’t shoot their features on a DV 4:1:1 camera? That might sound a little brutal. Sorry.
