6 months ago Some models of ESRGAN only supports 4x upscaling, so it's not a bug, just part of the process, choose another model like AnimeVideoV3 or Universal-fast-W2xEX if you want native 2x upscaling
Software Version Latest Stable (v3.113.01)
Describe the bug Whenever i try to upscale a 4K video to 8K using RealESRGAN-NCNN-Vulkan, the upscaled images(ScaledFrames) are upscaled to 16K(15360x8640) instead of 8K(7680x4320) which leads to an absolutely horrendous time to get it done. This only happens when using RealESRGAN-NCNN-Vulkan, as i have tried using Real-CUGAN-NCNN-Vulkan and it works as it should(also tried waifu2x-ncnn-vulkan, also works well), but i very much prefer the quality of RealESRGAN.(I have also tried on older versions to see if it was only a current bug or if it also happens on older versions, and yes, same thing)
How to Reproduce the bug Trying to Upscale a 4K Video to 8K(so setting it to x2 on Video) using RealESRGAN-NCNN-Vulkan
Expected behavior Upscaling x2 from 4K to 8K should yield ScaledFrames of 8K, not 16k.
