This Python script allows you to split a video into several smaller parts and then join those parts back together. It uses the moviepy library to handle the video operations and tkinter for the user interface.

The main motivation for creating this script was to facilitate the use of Topaz Video AI. Topaz Video AI is a powerful tool for enhancing video quality, but it doesn't allow pausing and resuming a task. By splitting the video into smaller parts, each part can be enhanced separately. After all parts are enhanced, they can be joined back together.

The script uses the following Python libraries:

• os
• tkinter
• moviepy

You only need to install moviepy:

• pip install moviepy

Note: os and tkinter are part of the Python Standard Library and should be available by default.

1. Run the script using Python 3.

• python split_join.py

2. The script will ask you whether you want to split or join videos. Enter '1' to split a video, or '2' to join videos.

3. If you choose to split a video:

   • The script will ask you how many parts you want to split the video into.
   • A file dialog will open for you to select the video to split.
   • A directory dialog will open for you to select where to save the split videos.
   • The script will then split the video into the specified number of parts.

4. If you choose to join videos:

   • The script will ask you to select at least two videos to join together.
   • After selecting the first two videos, the script will ask you whether you want to add another video. You can keep adding videos as long as you answer 'y'.
   • Once you answer 'n', a file dialog will open for you to select where to save the final joined video.
   • The script will then join all selected videos into a single video.

Enjoy your video processing!
