Hello , i have an issue with img2vid. i got below error when i try to create a video from an image. Zluda is active. There is no problem with image creating. How can i solve this ?

Console log :
!!! Exception during processing!!! CUDA out of memory. Tried to allocate 22.15 GiB. GPU

Buying a bigger GPU or looking into ways to make the VRAM requirements smaller. See if you can do fp8 unet

[hwxxzz]

i have 6800xt. i will check fp8 or i will buy new nvidia gpu :s

Since this is about amount of VRAM on your graphics card, 7900 xtx would probably be a better choice because it is way cheaper than RTX 4090 while having the same amount of VRAM. Tho not 100% sure how it compares to 3090 which iirc is the same too
