## Installation

```bash

## Usage

```python

from gradio_videoslider import VideoSlider

# --- 1. DEFINE THE PATHS TO YOUR LOCAL VIDEOS ---
#
# IMPORTANT: Replace the values below with the paths to YOUR video files.
#
# Option A: Relative Path (if the video is in the same folder as this app.py)
# video_path_1 = "video_before.mp4"
# video_path_2 = "video_after.mp4"
#
# Option B: Absolute Path (the full path to the file on your computer)
# Example for Windows:
# video_path_1 = "C:\\Users\\YourName\\Videos\\my_video_1.mp4"
#
# Example for Linux/macOS:
# video_path_1 = "/home/yourname/videos/my_video_1.mp4"

# Set your file paths here:
video_path_1 = "examples/SampleVideo 720x480.mp4"

### User function

The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).

- When used as an Input, the component only impacts the input signature of the user function.
- When used as an output, the component only impacts the return signature of the user function.

The code snippet below is accurate in cases where the component is used as both an input and an output.



 ```python
def predict(
    value: typing.Optional[
    typing.Tuple[
        str | pathlib.Path | None, str | pathlib.Path | None
    ]

    typing.Tuple[
