Tracking Duplicate Uses of Source Material

Cinema Tools makes it possible to track multiple uses of the same source material in your edited sequence. There are two basic reasons to do this:

In determining whether or not any frames have been used more than once, Cinema Tools assumes that, because of typical A and B roll film splicing (also called checkerboarding), at least one-half of a frame will be lost at both the In point and the Out point of each cut of film. In Cinema Tools, these frames are called cut handles. Some negative cutters may want to use more than a half-frame on each side of a cut. In the Export Film Lists dialog, you can specify up to five and one-half frames of cut handles. If you inadvertently include, in a sequence, frames that are needed as cut handles, Cinema Tools reports them as duplicate usages in the duplicate list and the double usage warnings.

It’s important to check for duplicate usages before you lock the picture and prepare to have the original camera negative cut. See Duplicate List and Double Usage Warnings to find out how to export a duplicate list and include duplicate usage information in a film list.

If you are editing your project as multiple sequences (for example, one sequence for each reel), it’s best to place all the sequences together before exporting a duplicate list. This way Cinema Tools can find duplicate usages across the entire feature. An easy approach is to place all the sequences into a nested sequence before generating a duplicate list.

However, when you intend to export a film list, do not nest part of one sequence into another sequence. Only whole-sequence nesting is supported when you export a Cinema Tools list. See the Final Cut Pro documentation for information about creating a nested sequence.
