Macro-from-Micro Planning (MMPL): a novel long-video generation paradigm that mitigates temporal drift and color shift, while enabling multi-GPU parallelization to generate longer videos.

Macro-from-Micro Planning Framework

Macro-from-Micro Planning

Overall framework of Macro-from-Micro Planning. Our method operates on two planning levels: (1) Micro Plans, which predict a sequence of future frames within each segment to mitigate local error accumulation, and (2) a Macro Plan, formed as an Autoregressive Chain of Micro Plans, where the planning frames of the first segment autoregressively generate the planning frames of subsequent segments, ensuring long-horizon temporal consistency.

Adaptive Workload Scheduling for Long Videos

Pipelined Parallel Generation for Long Videos

Adaptive Multi-GPU Workload Scheduling for Balanced Execution and Fast Autoregressive Video Generation.

Long-Time Video Generation

Our model generates high-quality 480P videos and supports streaming generation for extended durations. Below, we present 20-second videos (top), extended 30-second videos (middle), and 1-minute videos (bottom), all produced by our model without noticeable drift or color shift across time.

Longer and Better

Our method delivers substantially superior performance on 30-second long video generation, surpassing MAGI, SkyReels, CausVid, and Self-Forcing in both visual quality and temporal consistency. It robustly mitigates frame drift and flickering, while effectively addressing over-saturation and color imbalance, resulting in more stable and photorealistic outputs.

Limitation: Extrapolation Quality

Although MMPL mitigates error accumulation in long video generation, the substantial temporal span of long videos means that a single text prompt often aligns only with the early content and fails to capture the full video semantics. As generation progresses, the limitations of a static prompt lead to repetitive or even collapsed content in later segments. The examples below illustrate content repetition and quality degradation caused by using a single static prompt.
