This has turned into more of a puzzle than I’d thought. Doing the wrong thing works, and vice versa. Surely I must be doing something very basically wrong here.
1. In PS CS, I created 720×540 graphic. White (235/230/230) text over black background. Imported to FCP 720×486 timeline, the red line immediately appeared. I dissolved from graphic to live action, and rendered. Result: no jumps.
2. In PS CS, I non-proportionally changed the pixel dimensions of that same graphic to 720×486. In FCP, no rendering line. But two problems: (a) long vertical smear (faint but definite) at the right side of the last letter and (b) from the very first frame of the dissolve out to live action, the text jumps slightly larger, particularly in the vertical dimension. Putting a darker color on the font makes the smear even fainter but the dissolve still makes the text jump.
re: my earlier centering question: I was thinking that may be due to how I made the graphic inside PS, but it’s still inconsistent. For Graphic #1 (720×540) above: When I double-click the graphic to pop up its own timeline, and then double-click each layer, the black background layer is centered at 0, 0, while the text layer is centered at 4.5, -16. For Graphic #2 (720×486): 4.5, -14.5. That half-pixel makes the dissolve-jump especially troublesome, as it creates a doubling-up of the lower part of the font. When I change that to 4.5, -14, the moire effect disappears but the dissolve jump remains.
Thanks for wading through this tedious and annoying problem. Any insights would be most welcome. Or should I just wait for FCP Studio 2?
