A user shared their experience upscaling Minimax H3 generated videos using the Latent Upscaler node in ComfyUI.
- Results: Successfully upscaled a 0.5MP generated clip to 1080p with noticeable quality improvement.
- Performance: Processing a 15-second clip took approximately 20 minutes on an RTX 5080 (16GB VRAM, 64GB RAM).
- Comparison: Previously tried UltimateSDUpscale, which took about 30 minutes on the same system, making Latent Upscaler the faster option.
The author is asking the community if there are even faster methods for upscaling Minimax videos.
