# FrameInterpolate - ComfyUI Built-in Node Documentation

> Complete documentation for the FrameInterpolate node in ComfyUI. Learn its inputs, outputs, parameters and usage.

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/FrameInterpolate/en.md)

## Overview

The Frame Interpolate node creates new frames between existing ones in a sequence of images, effectively increasing the frame rate. It uses an AI model to predict what the intermediate frames should look like, which can be used to create smooth slow-motion effects or to increase the smoothness of a video.

## Inputs

| Parameter      | Data Type | Required | Range   | Description                                                                                                                |
| -------------- | --------- | -------- | ------- | -------------------------------------------------------------------------------------------------------------------------- |
| `interp_model` | MODEL     | Yes      | -       | The frame interpolation model to use for generating intermediate frames                                                    |
| `images`       | IMAGE     | Yes      | -       | A batch of consecutive images (frames) to interpolate between. Requires at least 2 images.                                 |
| `multiplier`   | INT       | Yes      | 2 to 16 | The number of times to multiply the frame count. For example, a multiplier of 2 doubles the number of frames. (default: 2) |

## Outputs

| Output Name | Data Type | Description                                                                                                                                                                                                      |
| ----------- | --------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `IMAGE`     | IMAGE     | A new batch of images with the interpolated frames inserted between the original frames, resulting in a smoother sequence. The total number of output frames is `(number of input frames - 1) * multiplier + 1`. |
