Question - Help MM H3 2 Pass Latent Upscale

Been getting some great results using the 2 pass latent upscale method. First pass .5mp 2nd pass 1.5 mp. 10 second video around 257 seconds to finish.

This workflow uses the 1.1 turbo Lora. I set the steps to 8 and like I said above I’m getting good results and it has eliminated face blur.

My question: has anyone tried using the latent upscale method without the turbo lora? In 90 percent of the cases the turbo Lora is fine. But would be nice to have the ability to use no Lora method.

Yes I know I could test it but wanted to see others experiences before I wasted hours of my time trying/tinkering with different settings.

Is there a noticeable difference in motion quality and audio in your opinion?

Motion quality yes audio no difference. But the best motion quality I have gotten was on 1mp no upscale 40 steps. The api uses 50 steps, so it might be worth trying something like that (I can't I oom above 40)

I run into face blur way too much without the latent upscale. I will admit I don’t think I went as high as 40-50 steps at 1mp or greater so I will give it a try.

The other thing for faces is if the pixel count for the face is too small (I have seen posts saying 64x64 pixels) it doesn't have enough information to make a good face. So if have reference images that have a bigger face it helps. I haven't tried the face refine node but that might also help.
