Steve's book is excellent and has a very informative chart but I'm still not sure. If possible, I want to pick one combination, if possible, and stick with it, one that works great for everything getting great quality with my HFS21 -projects that wind up on dvds and youtube projects as well. What's the best combination? Should it be AVCHD HD 1080 30 and shoot with 60i or ?
Another thing that I find confusing is that youtube seems to prefer non-interlaced. I don't particularf I shoot in 24f, which I believe is the only p frame rate available on this camera, and all the possibilities on Elements 9 are 30.
60i produces 30 interlaced frames, nicholas, so yes, you should use the AVCHD 1920x1080 Stereo.
And you should only shoot in FXP or MXP mode if you plan to edit in Premiere Elements.
