Something is badly amiss here. FCP should (does) handle motion on stills and looks very good to boot. Something is not right.
Are you rendering your timeline? FCP will attempt to play your timeline in realtime by dropping the resolution in order to play the motion paths. It will seem play without rendering, but you still NEED to render it. At times, it seems like FCP will not let you render. It “tells” you that it doesn’t need to render. Oh, but it sure does. Go under your Sequence pulldown menu and make sure that, under the three render pulldown choices, that ALL of the colors are checked, just to be safe. Change your RT settings on the upper left of the timeline to “safe”. (I’m in FCP 4.5 right now). Now, highlight every clip (CMD-“A”) and go back up to the Sequence pulldown and select Render All>Video. (hope I’m right…I’m going from memory on this one)
Anyhow, that should “force” CP to render your timeline. Things should look good now. I do “pan ‘n scan” all the time, and FCP does do a good job with it. I’m assuming that your stills are at least 720×480 for DV? Bigger can be better. Too big can actually degrade the finished product since you start to get all kinds of interframe flicker.
I’m in the process of loading a new G5 with FCP5 right now, but haven’t gotten to the point of being able to do an actual project yet. I’m told that FCP5 should handle this kind of sub-pixel rendering even better than FCP4.5. At least, that’s what they say…
Your finished video should look very good. Don’t get too discouraged at FCP yet. We also have two Avid Symphonys that do a lousy job at pan ‘n scan without additional plugins. Your system should look good. Keep at it. The quality you seek is in there.
