I get the above error when I generate video in 4k, I tried both using default upsampling of 0.5 in first stage and then setting the resolution to 3840x2160 and keeping resolution original at 1920x1088 but setting the upsampling to 1 so we end up around 4k in the end as well. Rendering with default settings works fine.
