fixups

Fixups are post hoc adjustments or additions made to a project to correct errors, refine details, or improve quality. The term is used across several domains, and its exact meaning depends on the context, but the common thread is a targeted correction applied after an initial pass or version.

In filmmaking and video production, a fixup (often called a pickup) is a small additional shot or scene shot after principal photography to fix problems such as continuity errors, performance issues, or missing elements. Fixups can be scheduled during shooting or added during editing, and they are integrated into the final cut to improve coherence and accuracy.

In computing, fixups refer to relocation adjustments applied to code or data so that a program can run correctly when loaded into memory at a dynamic address. They are managed by linkers and loaders and involve replacing placeholder addresses with actual runtime addresses. Fixups are organized in relocation tables or similar structures and are essential for both position-dependent and position-independent code. Depending on the executable format, fixups may cover base relocations, import address table adjustments, or other address corrections performed during linking or loading. Modern operating systems often perform these tasks automatically, but the underlying concept remains central to how software is mapped into memory.

The term can also appear in other fields to denote post-release corrections or refinements, such as repairs to data or maps after fieldwork or patches issued to fix known issues in software or media. Across domains, fixups share the core idea of targeted corrections added after an initial version.
