AI video that renders faster than real time

The real generation speed, what it costs, and a fact-check of the benchmark.

The short version

Use fal's H3 Max tool). fal currently advertises five free five-second 768p generations per day without signup, with native audio. Signing in adds five more daily generations at up to 15 seconds.

Start with a five-second 768p clip and `balanced` prompt expansion. That is the model's best low-latency test. The `quality` expansion mode can spend up to roughly 30 seconds rewriting the prompt before generation, which defeats the point when testing a live pipeline.
