Apple Final Cut Pro 7 - Manual (Page 1506)

Updating Projects from Final Cut Pro 5 or Earlier
Here are some things to keep in mind when updating projects created with Final Cut Pro 5
or earlier versions.
Nonmatching Sequence Clip Aspect Ratios
When you open projects created in Final Cut Pro 5 or earlier, Final Cut Pro deletes existing
render files for a sequence when the following are true:
• Your project contains a sequence whose clips have a different aspect ratio than the
sequence aspect ratio.
• The sequence clips with nonmatching aspect ratios have a filter applied that affects
the clip aspect ratio.
You can choose to delete the render files and continue to update your project or cancel
the project update, preserving your existing render files. Deleting render files cannot be
undone.
Shift Fields Filter
Projects created in versions earlier than Final Cut Pro 6 must be updated when they
contain incorrect or missing applications of the Shift Fields filter. For example, if you have
a Final Cut Pro 5 project where you edited a DV PAL clip into a standard definition (SD)
PAL sequence, Final Cut Pro 5 did not use the Shift Fields filter for combining DV and SD,
so Final Cut Pro 7 must update your project to add Shift Fields filters to clips when
necessary.
Note: In cases where you removed a Shift Fields filter from an earlier Final Cut Pro project,
Final Cut Pro 7 adds a new Shift Fields filter to any clip that needs one for proper playback.
Updating Projects from Final Cut Pro HD (version 4.5) or Earlier
Here are some things to keep in mind when updating projects created with Final Cut Pro
HD (version 4.5) or earlier versions.
Scaling Quality
Projects created in Final Cut Pro HD (version 4.5) and earlier used the Fastest option. If
you want higher quality motion transformations, you can choose Normal or Best. You
can change this setting later in the Video Processing tab of each sequence in your project.
For more information, see
“Rendering and Video Processing Settings.”
Removing Existing Render Files
You have the option to delete render files when your motion transformations are updated.
If you change the quality, it is a good idea to remove the existing render files to prevent
mismatched scaling qualities in your sequences. Deleting the render files cannot be
undone.
