Post-production is the phase of content creation that follows the completion of principal photography or primary generation, encompassing all the work required to transform raw footage and assets into a finished, deliverable product. It is the third major phase of production after pre-production (planning) and production (filming or generation), and typically involves editing, color grading, visual effects, sound design, music, and final output preparation.

In traditional film and television, post-production is often the longest and most complex phase of a production, with large-scale projects requiring months or years of work across specialist departments. The editing team assembles footage into a coherent narrative structure, visual effects artists integrate CG elements with live-action material, colorists grade the footage to the intended look, sound designers build the audio landscape, composers write and record music, and the final mix integrates all audio elements before the project is mastered and prepared for delivery in the required formats. Each of these disciplines requires specialized expertise, and the coordination of work across departments is itself a significant organizational challenge on larger productions.

In AI video generation workflows, post-production encompasses everything that happens after clips are generated - selecting the best outputs, assembling them in Compose on Morphic, applying color grades for consistency, integrating voice-over or music, adding motion graphics or titles, and exporting in the required format. Even when AI generation handles the visual production stage, post-production discipline - systematic review, intentional assembly, and quality refinement - determines the difference between a collection of generated clips and a finished, polished piece of content.
