ISI Summer Internship with VIMAL

This application allows users to upload a video file to the Angular UI with preview and playback and allows for conversion of the video to grayscale on the click of a button.
On button click, the video file is sent to a flask backend in a POST request where it is processed frame by frame and converted into grayscale and saved.
From there the processed file is sent back to the angular frontend where it can be played by the user.
