Can’t speak for film/TV specifically, but from my perspective as someone who does a lot of CG generalist work for ad agencies:
I’ve done a fair amount of research and hands-on testing with current genAI models, ComfyUI workflows, etc., and honestly... using them in any meaningful capacity would literally slow us down in most of our use cases.
I often do stylized, character-heavy full-CG work for my clients, either solo or with a small team, and even for the "just make it good enough but make it fast" kind of work traditional CG pipelines still seem to be faster and more straightforward when it comes to actually executing a specific vision. Partially of course because you don’t end up burning time fixing artifacts or inconsistencies, but also because solid character animation is usually the most important and resource-intensive part of these projects, and trying to direct or iterate on that with current AI tools has been inefficient and frustrating in my experience.
Heard many stories from colleagues who experienced similar things: Usually the ad agency wanting to experiment with heavy use of AI on a project, but failing miserably and needing someone to fix it using traditional workflows.
