# SeedVR2Preprocess - ComfyUI Built-in Node Documentation

> This node prepares a resized image or video for the SeedVR2 model by padding it to the shape the model expects.

This node prepares a resized image or video for the SeedVR2 model by padding it to the shape the model expects. It drops the alpha channel during processing; the companion Post-Process SeedVR2 Output node restores it later from the original resized image. Pixel values are clamped to the 0-1 range, the height and width are padded to multiples of 16, and the frame count is padded by repeating the last frame when needed.

## Inputs

| Parameter        | Description                   | Data Type | Required | Range |
| ---------------- | ----------------------------- | --------- | -------- | ----- |
| `resized_images` | The resized image to process. | IMAGE     | Yes      | -     |

Note: The input can be a single frame, a sequence of frames, or a batch of videos. If it has more than 3 channels, the alpha channel is dropped and only RGB is kept. The shorter edge of the input must be at least 2 pixels. Spatial padding is filled with black (value 0), and valid frame counts follow a 4n+1 pattern (1, 5, 9, 13, ...).

## Outputs

| Output Name | Description                        | Data Type |
| ----------- | ---------------------------------- | --------- |
| `images`    | The padded image for VAE encoding. | IMAGE     |
