In video generation APIs, the definition of "second" differs: some vendors bill by the duration of the generated video (result-oriented), while others bill by processing time or GPU occupancy time (resource-oriented), and the two may differ severalfold.

UnverifiedWhen budgeting for video generation, one should not multiply vendor A's "price per second" by vendor B's video duration, but should measure the total cost per video under the same resolution, frame rate, duration and feature set.75% similarUnverifiedReal-time video understanding models need to manage KV cache over long video streams; as video continues to play, the KV cache grows linearly, causing rising VRAM usage and increasing attention computation complexity71% similarUnverified"Faster than real time" means the time the model takes to generate 1 second of video is less than 1 second.71% similarUnverifiedReal-time video generation requires GPU-level computing power, and computational costs may limit large-scale commercial use, especially for mobile or console platform games.70% similar
