How does a local generative video upscaler (Wan 2.2 tiled) compare with Topaz and FlashVSR, and what settings matter?

Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. Mickmumpitz (2025-11-25): Wan 2.2 low-noise model in 81-frame batches with overlap blending and tiling; FP8 for 24 GB+ GPUs, otherwise GGUF sized to VRAM (Q5 for 12 GB; he uses Q8); LightX2V low-noise LoRA for fewer steps; optional realism LoRA; an ESRGAN-style pre-upscaler; auto-captioned prompt. Settings: target 2K as a good default; a quality pass adds ~30% quality for ~2x time (skip at 4K); "creativity" (denoise) low for fidelity, higher for degraded footage (risk visible tiles/subject change); save frames as fallback because stitching very long 4K outputs can crash ComfyUI. ~10 minutes for 81 frames; RunPod RTX 5090 ~$0.89/h. His comparisons: his 2K beat Topaz 4K on very poor footage; FlashVSR (via Pinokio) is more faithful and sharper on decent 720p input but struggles with very low quality. Use generative upscaling for AI-generated or badly degraded footage, faithful upscalers when accuracy matters. Curator qualifications: Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. Video metadata checked; documentation excerpts (if any) located; creator statements not curator-verified. Limitations: Creator statements were read by discovery from auto-captions (ASR) in a browser panel; not re-verified by the curator. Comparisons by eye on his chosen clips; no metric; Topaz model/version unstated. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
