What Is a Generator Clip?

Generators behave the same as other clips, but their content is actually generated internally in Final Cut Pro. Generators never refer to media files on the scratch disk, so they can never be offline as can clips that refer to media files. Because generators are generated by Final Cut Pro, their aspect ratio, dimensions, resolution, and codec are determined by the sequence they are edited into (unlike video and audio clips, in which these characteristics are based on the media files they refer to).
