A simple workflow to upscale latent Minimax H3 video to 2k using Nvidia-Open-H3-Regenerate-2K<ul><li>LoRAs can be downloaded here: <a target="_blank" rel="ugc" href="https://huggingface.co/Rkss/Open-H3-Regenerate-2K-lora/tree/main">https://huggingface.co/Rkss/Open-H3-Regenerate-2K-lora/tree/main</a></li></ul>They don't make much difference; use what you like.<ul><li><a target="_blank" rel="ugc" href="https://nvlabs.github.io/Sana/Open-H3-Regenerate-2K/">https://nvlabs.github.io/Sana/Open-H3-Regenerate-2K/</a> Sigma steps provided by NVIDIA. They start at 0.909, which adds a lot of detail, but will also change the scene. You can experiment with a low first sigma, like 0.7 or lower.</li><li>Stacking another turbo LoRA like Taomate 3 steps @0.5-0.7 strength also helps a bit. </li><li>In this workflow, I encode the source video to demonstrate; it is not required. You can generate a video at low resolutions, then chain &amp; upscale the latent directly </li></ul>
