What it does
Upscale and restore video in ComfyUI. Both the quick local path (per-frame ESRGAN like 4x_foolhardy_Remacri via ImageUpscaleWithModel + 4x→2x supersample, with its temporal-flicker tradeoff) and temporal-aware super-resolution (SeedVR2, the newer FlashVSR) with the downscale-first restore pipeline; RIFE/FILM frame interpolation via the BUILT-IN ComfyUI 0.26 FrameInterpolate (rife_v4.26 in models/frame_interpolation/) or the ComfyUI-Frame-Interpolation pack; 2x/4x scaling, VRAM tiers, VHS encode. Captures the classic downscale→SeedVR2→RIFE recipe and the current 2026 recommendation.
Video Upscaling & Restoration
Overview
"Upscaling video" in ComfyUI splits into three jobs, and the quality win comes from doing them in the right order:
- 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.
- Frame interpolation (VFI). Synthesize in-between frames to raise fps (e.g. 24→48/60) for smooth motion. Do this after the spatial pass.
- 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. Where a name is approximate or version-dependent it is flagged. Do not substitute a node you can't confirm is installed. Check with
install_custom_node(action: "list") /create_workflow (action:"node_info").
⭐ Recommended current pipeline (2026)
Downscale → SeedVR2 (temporal restore+upscale) → RIFE (interpolate) → VHS encode. This modernizes the user's classic recipe (below) with the current SeedVR2 node pack and is the path to ship by default. FlashVSR is the faster alternative for the restore stage (see "FlashVSR" section). Swap it in when speed matters more than absolute fidelity.
