Because hardsubs are images, you cannot simply right-click and save them. The process requires:
B — Frame replacement using clean plates It is a wrapper that combines the power
We will be using a Python library called videocr . It is a wrapper that combines the power of (for image processing) and Tesseract-OCR (the industry standard open-source OCR engine).
This review focuses on the latter. Because the text is part of the image, you cannot simply "demux" or extract it. You must essentially "watch" the video, identify pixels that look like text, and run OCR (Optical Character Recognition) to convert those pixels back into editable text.
