The local-first angle is the part worth underlining for anyone comparing this against hosted generators, and not only for the privacy reason. Running locally means you own the iteration loop. Most of the work in generated video is not the render, it is the twenty re-renders where you change one clause of the brief and watch what moves. On metered hosted services people stop iterating early and ship the third take instead of the tenth. Locally the only cost is time, which changes how you write briefs: you start testing one variable at a time instead of rewriting everything at once. Two things that seem to hold whichever route you take. Coherence degrades with clip duration in a fairly fixed order, hands first, then any text on signage or packaging, then background crowds, so three four-to-six second segments cut together beat one fifteen-second render. And describing direction beats describing speed: "walks left to right, out of frame" is far more reliable than "walks slowly", because slow is relative and direction is not. The one thing a local pipeline cannot give you is a read on how different model families interpret the same brief, since you are bound by what fits on your GPU. When I need that I run the identical brief through several hosted models and compare them side by side at https://soralum.com/video-ai/text-to-video , then bring the winning brief back to a local setup like this one for the actual iteration. Comparison hosted, iteration local, has been a reasonable split.
