V6 Update - New Lora LoaderAdded a new Lora Loader that works much better for our usecase. Check the list below for the GitHub link!Base InformationNow actually the fastest HQ audio + video generation workflow. See for yourself in the examples. I have intentionally created shots that show distant faces, because that is still a Minimax issue and no workflow issue currently. I can currently create these 8s, 1 megapixel videos in 3.5 minutes which is INSANE if you ask me, while keeping good audio!Keeping the First Pass resolution between 0.2 and 0.4 MP is completely fine for high quality output.I'm still experimenting with different scenarios, tweaking for the ultimate best balance of quality vs speed. There might be more updates very soon.WHY 2 MODELS AND REFINEMENT AT ALL??Yes, valid question. My answer: creating high resolution videos with the Fast H3 model takes much longer than this workflow, and the quality of the short Taomate turbo workflow is outright bad with low steps. The Solution: We use the power of the audio quality and base movement of the Fast H3 model while then using the ultra-rapid speed of the Taomate 3 step turbo lora to refine and enhance the video to High Quality!PLEASE let me know how this works for you!This is my very first attempt at making a FAST workflow that runs on my 16gb + 32gb System RAM Setup and I'm looking forward to see if you guys have the same results like me.This workflow uses 2 passes with 2 different models - the Fast H3 model + another normal T2V/I2V model. The first generates a smaller resolution video + the final audio, using the Fast H3 base model. The second pass refines the video into a higher resolution using the Taomate 3-Step Lora. Also Attention nodes are in use as well as Previews for the first and second pass seperately, so you can already decide if you want to keep generating the higher resolution video or not. This combination ensures good movement aswell as the good audio from the first pass while enabling high resolution generations in only 3 refinement steps at 0.35 denoise. Please try it out and let me know what you think!INSTRUCTIONS:<ul><li>Use the green nodes to configure your resolution, aspect ratio &amp; duration</li><li>Keep the aspect ratio the same for the first pass and second pass resolution selector</li><li>Add your desired LoRAs in the purple node</li><li>Enable or Bypass your desired 1st Frame or Last Frame input Image Groups on the left side of the workflow</li><li>Adjust to your desired VAE's, text encoders that you might already have (I'm using a new KJ video vae that is smaller)</li><li>Don't forget to adjust the filename and path in the Save Video node to your prefered syntax and location (the one in the workflow creates this type of filename syntax with MP, date and time of generation: 1MP_Video_210926-150209_24fps_00001_.mp4)</li></ul>MODELS<ul><li>Fast H3 Model: <a target="_blank" rel="ugc" href="https://huggingface.co/FastVideo/FastVideo-FastH3-Comfy/blob/main/diffusion_models/fastvideo_fasth3_8step_v2_pruned_int8_convrot.safetensors">https://huggingface.co/FastVideo/FastVideo-FastH3-Comfy/blob/main/diffusion_models/fastvideo_fasth3_8step_v2_pruned_int8_convrot.safetensors</a></li><li>Base FLF2VA / T2V model: <a target="_blank" rel="ugc" href="https://huggingface.co/Comfy-Org/MiniMax-H3/blob/main/diffusion_models/minimax_h3_fl2va_pruned_int8_convrot.safetensors">https://huggingface.co/Comfy-Org/MiniMax-H3/blob/main/diffusion_models/minimax_h3_fl2va_pruned_int8_convrot.safetensors</a></li><li>Text Encoder: <a target="_blank" rel="ugc" href="https://huggingface.co/Comfy-Org/MiniMax-H3/blob/main/text_encoders/qwen3vl_32b_minimax_h3_int8_convrot.safetensors">https://huggingface.co/Comfy-Org/MiniMax-H3/blob/main/text_encoders/qwen3vl_32b_minimax_h3_int8_convrot.safetensors</a></li><li>Video VAE: <a target="_blank" rel="ugc" href="https://huggingface.co/Comfy-Org/MiniMax-H3/blob/main/vae/minimax_h3_video_vae_int8_convrot.safetensors">https://huggingface.co/Comfy-Org/MiniMax-H3/blob/main/vae/minimax_h3_video_vae_int8_convrot.safetensors</a></li><li>Audio VAE: <a target="_blank" rel="ugc" href="https://huggingface.co/Comfy-Org/MiniMax-H3/blob/main/vae/minimax_h3_audio_vae_fp32.safetensors">https://huggingface.co/Comfy-Org/MiniMax-H3/blob/main/vae/minimax_h3_audio_vae_fp32.safetensors</a></li><li>Taomate 3 Step Turbo Lora: <a target="_blank" rel="ugc" href="https://huggingface.co/drbaph/MiniMax-H3-Turbo-Lora-ComfyUI/blob/main/experimental/minimax_h3_taomate_fl2va_3step_ema_comfyui.safetensors">https://huggingface.co/drbaph/MiniMax-H3-Turbo-Lora-ComfyUI/blob/main/experimental/minimax_h3_taomate_fl2va_3step_ema_comfyui.safetensors</a></li><li>H3 Latent Upscaler: <a target="_blank" rel="ugc" href="https://github.com/LBH-123-AI/Comfyui_Minimax_h3_latent_Upscaler">https://github.com/LBH-123-AI/Comfyui_Minimax_h3_latent_Upscaler</a></li></ul>Custom Nodes Links<ul><li><a target="_blank" rel="ugc" href="https://github.com/siraxe/ComfyUI-SA-Nodes-QQ.git">https://github.com/siraxe/ComfyUI-SA-Nodes-QQ.git</a></li><li><a target="_blank" rel="ugc" href="https://github.com/rgthree/rgthree-comfy">https://github.com/rgthree/rgthree-comfy</a></li><li><a target="_blank" rel="ugc" href="https://github.com/kijai/ComfyUI-KJNodes">https://github.com/kijai/ComfyUI-KJNodes</a></li><li><a target="_blank" rel="ugc" href="https://github.com/xmarre/Comfyui_Minimax_h3_latent_Upscaler-Plus">https://github.com/xmarre/Comfyui_Minimax_h3_latent_Upscaler-Plus</a></li></ul>GENERATION SPEED:On 5070Ti with 32gb System RAM:<ul><li>8 seconds - 1 MP resolution: ~3:30 minutes</li><li>8 seconds - 0.5 MP resolution: ~1:45 minutes</li><li>10 seconds - 1 MP resolution: ~4:30 minutes</li><li>10 seconds - 0.7 MP resolution: ~3:10 minutes</li></ul>OLD UPDATE INFOV5 Update - I2V AdditionPer request, this workflow has been enhanced for I2V usage with a new group selector that enables you to inject a first and/or last frame.V4 UpdateRemoved old deprecated Sol-Attn nodes from Kijai and replaced them with Comfy Kitchen Attention. Also, small adjustments to improve quality further. Model links now all included in this description down below.

Minimax H3 - I2V/T2V - Fast H3 8-Step + Taomate 3-Step, 2-Pass WF - The FASTEST workflow for HIGH RESOLUTION SFW/NSFW videos

Removed SolAttn node as it was deprecated and is now replaced by comfy kitchen attention. Also made some small adjustments to make sure the audio quality stays good.
