Minimax H3 advanced workflow for creating long videos with motion context (Nikodemon80's H3 Motion context custom node) using another generated video or starting from scratch. No need to save and load latents at each stage. Generation can be resumed from any stage if any changes are needed using ComfyUI's internal mechanism.

Basic functionality:

1. Choose between Sampling or "Start with video" depending on if you want to start from scratch or from a generated video.

2. If Sampling from scratch enter width/height in nearby blue widgets and images in first/last frame. In "start with video" mode, they are bypassed and taken from video size.

3. Enable stage groups for number of generations.

4. 4 step turbo LoRA is applied in models subgraph.

5. Separate LoRAs can be applied to each stage using the power lora loader node in each stage.

6. Generation can be resumed from any stage if you want to change something.

7. Generation can be extended to your device's capabilities by replicating "Stage 4" group any number of times and connecting in similar fashion.
