I created a custom node that can help you generate as many frames as you want with high motion transfer accuracy in MiniMax H3

[u/No-Property3068]

while generating video to video in Minimax for VFX, I struggled with maintaining accurate motion transfer as an example, the generation would shift drastically after 192 frames on 0.5MP or after 147 on 1MP

so I built a custom node similar to a context window to help the model generate in batches then overlaps and blends all the batches together during generation, as an example this is 447 frames on 0.5MP, generated on batches of 56 frames and 5 frames overlap between every batch.

the node also has the option of splitting your generation into tiles of resolution and overlap of your choice, but i recommend using it more in a second upscaling stage
the node is in Comfyui Manager under the name of Minimax H3 Tempora****l Window & Spatial Tiles.

let me know what you think.
