This workflow demonstrates how to upscale and restore images using SeedVR2 3B Int8, a one‑step diffusion-based video restoration model adapted here for still images and frame-by-frame processing. The core of the graph is a SeedVR2 inference node (id: 1970dcb4-982a-4c01-a373-4d239a3041e4) configured for the 3B Int8 weights and paired with the provided VAE (seedvr2_ema_vae_fp16.safetensors). You load your source with LoadImage, route it through the SeedVR2 node for enhancement/upscaling, compare results with ImageCompare, and finalize with SaveImage. A MarkdownNote in the graph provides inline guidance and links.
Technically, SeedVR2 performs a single forward pass to restore detail, reduce compression artifacts, and upscale, avoiding iterative denoising. The Int8 quantized 3B variant reduces VRAM usage and speeds up inference with a small quality trade-off versus full precision. While SeedVR2 is trained for video restoration and improved temporal consistency across sequences, it also produces strong results on individual images. If you process frame sequences consistently (e.g., exported video frames), the model’s training tends to yield visually stable outputs from frame to frame even when used one-at-a-time in ComfyUI.

كل سير عمل في Comfy هو رسم بياني بصيغة JSON. الحمولة أدناه هي هذا سير العمل بالضبط كما يشغله ComfyUI — يمكنك جلبه من الرابط، حفظه في نظام التحكم بالإصدارات، أو تحميله في ComfyUI وتشغيله عقدة تلو الأخرى.
شغّله من TypeScript أو Python باستخدام Comfy SDK. نفس الكود يعمل على Comfy Cloud أو ComfyUI الذي تستضيفه بنفسك — فقط عنوان URL الأساسي يتغير.
