ComfyUI Extension: Smart Resolution Toolkit
Resolution picker and latent generator for ComfyUI. Select presets like HD, FullHD, 2K, 4K, 8K with aspect ratios (1:1, 9:16, 4:5, 21:9 etc.) via dropdowns. Automatically snaps width/height to latent-safe multiples of 64. Ideal for EmptyLatentImage, AnimateDiff, ControlNet, video formats, and KSampler workflows. Outputs clean INT values or ready-to-use LATENT tensor.
