What's new ?

V1.0
This workflow allow to easily generate video using Minimax H3 and upscale them in high resolutions using chunking and frame interpolation for better quality.
Node colors have meaning:
Red: one time models configuration
Yellow: my personal config, feel free to adjust it if does not suit you
Green: node you will often edit to adjust video generation
Black: Informations to understand how some nodes works
Getting start
Fill the "Prompt, Loras and References" group with your prompt and ressources
Adjust "Video duration", "Video settings (1st pass)" nodes in "First pass: Generate video" group
Adjust "Upscale Resolution Selector" node in "Second pass: Upscale" group
Then Run !
Custom changes
Use the "Bypass groups" node to bypass groups you don't need
By default, the non upscaled video is not saved. You can save it by choosing the "Save" button ("Preview" is selected)
By default, the workflow use "Temporal chunk" and "RIFE" to save VRAM and up the framerate to 60 FPS on the final video
For low VRAM, you can use the "Spatial Chunk (Save even more VRAM)" node to split even more the chunking
After each generation, the VRAM is free with the nodes "Free VRAM" for each pass. Feel free to bypass them if don't need them.
