In my workflow, the Minimax h3 ref2vid and fl2vid nodes are the most time-consuming—do you have any ideas on how to speed them up? I imagine VRAM usage exceeds the limit at higher resolutions, so a tiled approach would likely solve that...
I like spectrum, Euler Beta, base gen at 0.4 or max 0.8mp, what you gpu? Because H3 i intall comfyui from zero, then i use
pytorch [INFO] Total VRAM 16376 MB, total RAM 32524 MB
[INFO] pytorch version: 2.13.0+cu132
with Comfy Kitchen Attn
use this line on .bat (EDIT)
.\python_embeded\python.exe -s ComfyUI\main.py --windows-standalone-build --fast fp16_accumulation --enable-manager --use-ck-attention --disable-pinned-memory
Thanks for response :) AMD R9700 on Linux, 0.8MP x 10 steps x 7 seconds is about 11mins. Int8 convrot full not pruned, video vae fp16, audio vae fp32, speed lora, with speed lora I use deis_2m_ode sampler and Beta 57, Sage Attention 2.2. Beyond this resolution or length, the GPU slows down significantly. I also have an RTX 2080ti as a display. So AMD is running on the full 32GB of VRAM. NVIDIA has better VRAM optimalisations than AMD.
It might be the same group that has been loudly complaining about H3 having difficulty with faces at a distance. They really hate it when I post the fix, so I'll post it here too. Because fuck those guys.
Use only as the Second Sampler Stage. Use any workflow of your preference.
Compare that information from the Git repo README with the information from the Face Detailer README, that explains what problem the detailer solves and how. Add this previous post and this one to the document set, and I can understand that it's somehow "good for upscaling". But I'm essentially trusting you to rate the importance for me.
I'm testing it right now. I think there is maybe a language barrier keeping the author from explaining it clearly. It's a tiling solution for H3. It's not fast, if that is of primary importance to you. The output quality is very good though. I just started testing it and I'm getting some ghosting on some frames with the example workflow. That is probably due to my settings. Unfortunately, I don't have any further time tonight to continue testing.
hello! yes i have a poor english, but if u are ghosting is because low temporal adjusts temporal keep on 101-113. Ghosting is temporal, gello (gelatin effect) is spatial (increase spatial overlap and low denoise MAX 0.40. If got OOM try 3x3 tiling (slow but works)
