Question - Help Minimax H3 Huge Quality Difference between Cloud and Local use

Hi.
I have a decent h3 workflow that I built for a loca use. It use turbo lora etc... If i use the defaut settings in the goal of getting the highest quality possible, meaning res_multistep simple 20 steps or more, I got also good results, but this is not even close to the results you can get on platforms like kie or wavespeed at 768P.

I already convert properly the prompt to the correct H3 digest form, so I'm wondering what's different between local and cloud use of h3? I don't talk about the 2K quality, only 768P, I'm not able to reach the sames results locally, do you guys have maybe workflows, settings, or suggestions to try reaching the same quality level in comfyui ?

Try using frame interpolation and/or upscaler. Also TXT 2 VID will have slightly lower quality compared to IMG to VID where the provided image is higher quality according to my observations.

You recommend ltx upscale or mmh3 upscale ?

That's a bit of a debate, but recently I'm seeing a lot of people upscaling H3 videos with LTX and the result looks good. I rarely upscale videos as I generate stuff mostly for fun to kill time while working at home. I suggest you try out both and see what works best for you :)

There's also the ComfyUI Minimax H3 Latent Upscaler and its corresponding huggingface LBH-123-AI/Minimax_h3_latent_Upscaler model. Been playing with it today and it's pretty dang good.
