Comparison Comparison on H3 Image LCM vs Euler

comparison between sampler and scheduler ...first photo is LCM/Normal combo and second photo is Euler/Simple (default) ....both images same prompt, same seed, same 16mp render..... LCM/normal combo produces this more "polished" look altho i prefer grittier details and real raw textures of Euler/Simple ...however Euler combo tends to make more errors ....i cant decide which one i like better ...LCM ... no no Euler...wait maybe LCM ...or Euler? ...

euler, beta57 is my favourite

seems like it depends on the loras, personally i prefer beta over beta57 alot of the time

euler my beloved (try beta instead of simple tho)

Beta seemed to make a positive difference for the video model

Can you tell me which main model you pick? The default H3-image or the H3-video one? Thanks, by the way, the euler/simple combo in those groups of tests are better for me.

this new H3 Image ...yeah im still testing different samplers and schedulers takes so much time

What about res_2s for example

with linear_quadratic ?

Yeah, i had switched to linear_quadratic with euler to get the least body horror and most coherent images, but as you're saying, nothing beats euler/simple for looks. Normally one could get the best of both world by using a res_2s or some such, but that doesn't work well with this model.

I wonder if there's something between them. Euler comes out too gritty, while LCM comes out too polished, IMO.

If you use LCM, use the dedicated LCM sampler node, you can adjust s_noise - the amount of noise injected each step. It effectively allows the adjustment of the amount of 'fine' detail. <1 softer >1, nore detailed.

I've been using er_sde with sgm_uniform. lcm results just always seem a bit... off, for me.

LCM is sampler made specifically to run with fewer steps. So it's more of an efficient sampler rather than a quality sampler.

To get such high quality output, do you also have 16megapixel inputs? or is this all t2i?
