# 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 (plus 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.
