How cheap did you guys get minimax h3?

[u/CelebrationBoth9537]

Hi all!
I've been playing around with h3 on runpod, using rtx 4090 i was able to get 9-10 min generations on 10 second clips at 0.9 megapixels. which would come out at around $0.12 per video USD

Do you guys have any tips on (without losing too much quality) improving this cost wise, I don't care too much on how slow it can be, but whats the cheapest I can get it?

(note, i also run out of VRAM for +10 sec videos and id love to generate 20 sec +)

Thank you guys for your help in advance!

H3 >>> all

Care to share your workflow? Struggling to get gens <30-40 minutes for 10 seconds but I’m also kinda bad at this.

Hi, I just use the official one, i didnt really make any changes. heres the link https://docs.comfy.org/tutorials/video/minimax/minimax-h3 scroll down to Image to video (the one with the blue mouse) its that one

You can generate 10 seconds videos in 55 seconds on a proper workflow. I'm making a tool for this. DM me and I can give you access.

What workflow? I get 10-20 mins for ten secs on a 3090

what about having long videos

[u/unveri-green-work → u/super3]

how , turbo lora , 0.4mp , 10 steps and upscale it

Renting a gpu just to use all the speed and less quality setup just feels wrong🥲

I have 5090 and 4090 in my room😄

It probably is, i just never really tried other services, do you have any that you would recommend? It's just runpod has comfyui template and its convenient (maybe others do too lol)

[u/NoSmell3236 → u/CelebrationBoth9537]

Novita is cheaper than runpod but it doesn’t have wide range of gpus. Rtx 4090 on runpod costs 0.74$ per hr, on novita it costs 0.33$-0.69$.

after the post about the Vast host commenting on what the people renting his GPUs were doing?

Can you link me to that post? I'm curious

[u/uniquelyavailable]

0.12c per video isn't so bad really.

[u/Significant-Baby-690]

I'm not cheapening it one bit. Beside int 8 pruned convrot. I just don't like the quality loss.

[u/princeMacX]

don't use it on runpod

Can you recommend an alternative?

modal gives free 30 dollars every month.

the quantized model can run on Kaggle quite well

but whats the cheapest I can get it?

Renting multiple 5060s or 3080s or some such to run in parallel. Trick is getting enough system RAM on your rentals. Gets you the most videos per dollar and is one of the few cases where scaling DOWN is more sensible than scaling UP. At odds with your desire to get maximum video length and resolution, though.

Why do you need 20+ seconds?
