UpscalingUploaded a fix and reworked a few things to explain better how to start.This can help remove contrast drift from extending videos somewhat.First dive into subgraphs...This was made to upscale minimax videos in batches to allow smaller longer videos be upscaled to higher res.Can make a video or load a video you already have.Not sure if i made it clear, all the normal refs that are used for the base video generation, are also used for the upscaling of your loaded video too.Included a version with face fixing at the end.<hr />V3Advanced minimax- generate videos from ref images.- advanced extend videos- use custom audioincludes a beta flow for face fixing that allows batching.<hr />Minimax face fixing (inpaint)This is my old vace workflow edited to use minimax instead.Old vace flow - <a target="_blank" rel="ugc" href="https://civarchive.com/models/2570937/wan-vace-21-flow-archive?modelVersionId=2894367">https://civarchive.com/models/2570937/wan-vace-21-flow-archive?modelVersionId=2894367</a>- Cuts out faces to inpaint.- Can keep/change/create audioEnjoy :)<hr />V2Simple minimax- generate videos from ref images.- Simple Extend videos- Beta memories for extending- use custom audioI dont think i explain everything well enough, if any questions ask in comments i will add any answers to the next flow.<hr />Best ref2va distilled lora<a target="_blank" rel="ugc" href="https://huggingface.co/Kijai/MiniMax-H3-experimental/tree/main">https://huggingface.co/Kijai/MiniMax-H3-experimental/tree/main</a><a target="_blank" rel="ugc" href="https://huggingface.co/Kijai/MiniMax-H3-experimental/blob/main/loras/MiniMax-H3-Ref2VA-Acc-8Step_pruned_comfy.safetensors">MiniMax-H3-Ref2VA-Acc-8Step_pruned_comfy.safetensors</a>Strength 0.4-1.0I debated releasing this as its not much more than the basic comfy workflowWhy use minimax- Great prompt listening- Combine multiple subjects easily.- Quality lip sync and voice clone- 5-15 second video clips 300 frames at 1MP.- You want to create a story.This uses A LOT of resources, crashed a few times, soft locked too when i went too big, but 1MP is not a tiny video when i ran about the same for LTX and much smaller for vace. Its slow, but its doing more than most.I think it can extend like vace could, and without a contrast shift. Its down to learning the prompting to extend from the last 8 frames of a video.Minimax is a beast for storytellers.(fyi my gpu is stuck on PCI3 atm due to my cpu)From clean load of comfy loading models and render of 1MP 311 frames at 8 steps took with my setup 23 min 21 seconds 158s/iOutput is 1376x768 at 12.75 seconds

Minimax.. simple

This is my old vace workflow edited to use minimax instead.- Cuts out faces to inpaint.- Can keep/change/create audioEnjoy :)
