I usually upscale 360x240 15 fps 3-minute videos (2700 frames) by 3x, or sometimes 4x. I have 16 GB of VRAM and 96 GB of DDR5.

3x - batch_size=77
4x - batch_size=49

I use this.

1080/240 = 4.5x upscale. And you want a batch_size of 125.

I don't think regular GPUs can handle the settings you mentioned. You need a server GPU with at least 80 GB of VRAM.

thanks for the info,pro 6000 is the proper GPU then

I don't think it will work. But you can try, of course. To minimize OOM errors, only the startup settings and node settings need to be correct; I've done months of testing on this, and honestly, I haven't seen any benefit from anything else.
