vspreview: Debanding Problems

jay123210599 · 16th March 2025, 05:06

I tried to deband a video in vspreview, but I got this error and the deband video was just a black screen. How do I fix that?

Looks like a Vulkan issue and not enough memory. You could also try neo_f3kdb, which is a good debander for anime.

I have a Geforce RTX 3090. How does that not have enough memory?

Fair enough. It says it could not allocate 8 MB, so there is some memory-allocation issue.

To be honest, I don't know.

jay123210599 · 18th March 2025, 18:39

I just figured it out, I needed to replace my old libvs_placebo.dll file with an newer version of it.
