Another issue here with my 5090. At the end of the generation, it says ffmpeg cannot be found but I have it installed and on path. Is this a common issue?

Furkan Gözükara SECourses•3/15/25, 11:55 PM

it is its logic

Furkan Gözükara SECourses•3/15/25, 11:55 PM

based on previous weights it skips next

I'm checking wan 2.1 in replicate and the default is 30 steps with a maximum of 40. Maybe the default 50 steps we have here is too many.

Furkan Gözükara SECourses•3/16/25, 12:26 AM

surely you can reduce

Furkan Gözükara SECourses•3/16/25, 12:26 AM

replicate is always about making more money = lower quality

JaviEM•3/16/25, 12:28 AM

I have tried 15 steps and the quality is decent. 30 should be enough to get good quality

GasbyOP•3/16/25, 12:41 AM

New WAN app works flawlessly doc. Thanks

asap17z•3/16/25, 1:23 AM

What’s teacache and why is it only giving me errors on mass compute and runpod but not on my system( I used conda and pip for my system)

asap17z•3/16/25, 1:34 AM

Comfyui vs gradio. I prefer Comfyui for everything else, but ever since I started using your wan2.1 example I could control how it use my gpu, thereby making it possible to use my system for other things outside of wan, with Comfyui it almost impossible to do so, even on a 4090. Although there are bugs on the runpod and mass compute example you provided. I would appreciate it you can find a solution for them

J2_Nedo•3/16/25, 9:21 AM

i tested 20,30,40, and 50 steps with the same seed, 50 gives the best quality, at least thats what i found out, but for quick testing i use lower steps

GGasby New WAN app works flawlessly doc. Thanks

which zip file you used on massed compute and runpod?

Furkan Gözükara SECourses•3/16/25, 11:31 AM

also guys i am about to fix an error with image to video models

Furkan Gözükara SECourses•3/16/25, 11:31 AM

we were supposed to load models_clip_open-clip-xlm-roberta-large-vit-huge-14.pth as FP32

asap17z•3/16/25, 11:31 AM

wan21_v31

Furkan Gözükara SECourses•3/16/25, 11:31 AM

we were loading as BF16

Furkan Gözükara SECourses•3/16/25, 11:31 AM

i am testing

Aasap17z wan21_v31

Furkan Gözükara SECourses•3/16/25, 11:31 AM

v35 should work

Furkan Gözükara SECourses•3/16/25, 11:31 AM

Furkan Gözükara SECourses•3/16/25, 11:31 AM

which I will publish

asap17z•3/16/25, 11:32 AM

Furkan Gözükara SECourses•3/16/25, 11:34 AM

Furkan Gözükara SECourses•3/16/25, 11:35 AM

it will also fix fp8 loading for image to video

Furkan Gözükara SECourses•3/16/25, 11:38 AM

wow FP8 really reducing VRAM

asap17z•3/16/25, 11:40 AM

okay sir

Furkan Gözükara SECourses•3/16/25, 11:43 AM

I should re-set params BF16 vs FP8

FP8 really reduces VRAM a lot

asap17z•3/16/25, 11:46 AM

okay, I just downloaded it.

asap17z•3/16/25, 11:50 AM

I'm going to test this Gradio version along side with my Comfyui workflow on Runpod and mass compute. but I prefer using your version on my system because it's better optimize for consumer pc
