Remaster is the preset that treats video as a sequence, not a stack of stills. The engine job is temporal upscale to 4K: one pass that carries detail from frame to frame so fine texture holds steady instead of shimmering. That family is RealBasicVSR-style video super-resolution. Natural is the default detail mode; Crisp is the same job, sharper.

It needs an NVIDIA GPU, the optional GPU add-on pack when you request it, VSR weights, and about 12 GB of VRAM. The UI warns below that. Cards that cannot hold the recurrent graph still run Export Ready.

CUDA is how Remaster runs, which is why the preset is NVIDIA-only. Without NVIDIA, Remaster is simply unavailable; denoise and per-frame upscale can still take ncnn or CPU paths.

What this post can defend is the recipe, the hardware gate, and the fact that the clip never goes to a datacenter to finish the pass. Side-by-side scores need a corpus and a protocol; that is a post of its own. Read Remaster for the operator checklist.
