238 "# About SeedVR2 Video Upscale\n\n## How Resolution Works\n\nThe **Resolution** setting in the `SeedVR2_VideoUpscaler` node is based on the **height** of your output video. Think of it the same way you'd refer to standard video resolutions:\n\n| Resolution Setting | Output Example (16:9) |\n|----|-----|\n| 1080 | 1920×1080 (1080p) |\n| 1440 | 2560×1440 (1440p) |\n| 2160 | 3840×2160 (4K) |\n\nSo if your source is 1280×720 and you set Resolution to `1080`, the output will be **1920×1080**.\n\n## Preparing Your Input\n\nUse the **Image Scale** node before the upscaler to downscale your input to the correct starting size. The upscaler node will **center-crop** the input to ensure the final output lands on the correct aspect ratio, so getting your input dimensions right beforehand avoids unexpected cropping.\n\n## Performance Note\n\nHigher target resolutions require significantly more processing time. If you're experimenting or iterating, start at a lower resolution to dial in your settings before committing to a full 2160p render."
