During editing, Photo to Movie does not usually need to know the final size of your movie. It will rescale any photos to the final size when you make your movie (see Making your movie).
It is useful, though, to get a warning if your key frames become so small that the final output will become pixelized. If the size of a key frame falls below the minimum size required for specified movie size, the size of the key frame displayed in the inspector will turn red to warn you.
To specify the movie size
-
On Mac OS, choose
→ or click on the button in the tool bar. -
On Windows, choose
→ or click on the button in the tool bar. -
Enter the intended movie size.
If you are editing for standard DVD, the movie size should be 640x480.
If you are editing for High Definition, the movie size should be either 1280x720 (720p) or 1920x1080 (1080i or 1080p).
