Minimax H3 INT8/INT4 Convrot Sampler settings I currently use are: er_sde/res_multistep simple Just uploaded both FL2VA &amp; REF2VA w4a8_mixed models quantized by Kijai. (Makes my mixed int4 models obsolete) True int4 model size with int8 activations, near int8 quality, same speed as int8. For RAM/VRAM-constrained systems. Update your ComfyUI to the latest version for support of the new w4a8 (Should be included in Stable ComfyUI v0.31.0 <a target="_blank" rel="ugc" href="https://github.com/Comfy-Org/ComfyUI/pull/15308">https://github.com/Comfy-Org/ComfyUI/pull/15308</a> FL2VA - first last (frame) to video / audio REF2VA - ref_images / ref_videos / ref_video_audios / ref_audios: up to 9 reference images, 3 reference videos (each may carry its own paired soundtrack), and 3 standalone reference audio clips Both models can generate t2v (Text to video), i2v (Image to video), v2v (Video to Video), a2v (Audio to video), and multiple references (image/video/audio). But were further fine-tuned/trained for higher-quality outputs for the intended use.
