# Video Upscaling & Restoration ## Overview "Upscaling video" in ComfyUI splits into three jobs, and the quality win comes from doing them in the right order: 1. **Spatial restore + upscale** — a *temporal-aware* model that increases resolution **and** cleans compression blocks, blur, and AI-gen mush while keeping frames consistent over time. This is the part a plain image upscaler (ESRGAN, UltimateSDUpscale per-frame) does badly — per-frame upscalers **flicker** because each frame is sharpened independently. Use a video model. 2. **Frame interpolation (VFI)** — synthesize in-between frames to raise fps (e.g. 24→48/60) for smooth motion. Do this **after** the spatial pass. 3. **Encode** — mux frames (+ original audio) back to an MP4. The two leading temporal restorers in 2026 are **SeedVR2** (diffusion-transformer restorer, the proven workhorse) and **FlashVSR** (newer one-step streaming VSR, faster). Frame interpolation is **RIFE** (or FILM) via **ComfyUI-Frame-Interpolation**. > ⚠️ Verification note: every node/pack/model name below was confirmed against the > GitHub repos and the ComfyUI registry / Manager as of June 2026.
