PlayGrid is a Python-based web application that offers various functionalities related to video and audio processing. It leverages popular libraries such as Flask, MoviePy, AssemblyAI, IMDbPY, Selenium, and more. Below, you will find an overview of the main features and how to run the application.

1. Video and Audio Extraction: The application allows users to upload video files (.mp4, .mov, .mkv) and extract the audio, which is then saved in .wav format. The extracted audio is used for further processing.

2. Automatic Subtitle Generation: PlayGrid utilizes the AssemblyAI library to automatically generate subtitles from the extracted audio. The subtitles are saved in .txt format for each uploaded video.

3. Text-based Plagiarism Detection: Users can upload text files, and the application performs text-based plagiarism detection by calculating the similarity score between the uploaded text and the generated subtitles for each video.

4. IMDb Movie Search: The app integrates IMDbPY to search for movies on IMDb based on user input. It opens the movie's page in a web browser.

5. Video Similarity Detection: PlayGrid allows users to upload multiple videos (.mp4, .mov, .mkv) and calculates the similarity score between the extracted features of each pair of videos. The similarity scores are displayed as a percentage on the user interface.

6. Web Scraping for Subtitles: The application uses Selenium to scrape subtitles for movies from the Subscene website. Users can input the movie name, and the application will attempt to fetch the English subtitles for that movie.
