How to Extract Hardcoded Subtitles from Video Files

Tutorial - How to Extract Hardcoded Subtitles from Video Files. Finally, here is a simple way to extract hardcoded subtitles from video files for free. It will help to have basic knowledge about ffmpeg. You will need to be patient if your video file has a lot of hardcoded subtitles. You can try this tutorial on a short video clip that has hardcoded subtitles to see how it works. A lot of movie trailers have hardcoded subtitles. Part 1 - Here is is the ffmpeg script to crop the video.mp4 file used in this tutorial. Please adjust parameters according to your video file and note the file extension ffmpeg -i video.mp4 -filter:v "crop=1850:250:0:830" -c:a copy video-cropped.mp4 Part 2 - This is the ffmpeg script to embed timestamps in video-cropped.mp4 ffmpeg -i video-cropped.mp4 -vf "drawtext='timestamp: %{pts \: hms}': x=0: y=40: fontsize=36:fontcolor=black: box=1: boxcolor=white" -c:a copy video-cropped-timestamps.mp4 Editted on 6th, May, 2022: As most hardcoded subtitles are in white, it makes sense for the timestamps to have the same color. I got better results with white fonts and no box during the OCR process. The script for this is as shown below: ffmpeg -i video-cropped.mp4 -vf "drawtext='timestamp: %{pts \: hms}': x=20: y=40: fontsize=40:fontcolor=white" -c:a copy video-cropped-timestamps.mp4 Part 3 - This is the ffmpeg script to create image files from video file video-cropped-timestamps.mp4 ffmpeg -i video-cropped-timestamps.mp4 -start_number 1 -vf fps=1/2 video-%04d.jpg Tip: I find using Adobe Bridge (Free but you need Adobe ID) very helpful to mark images that you want to keep that have the first subtitles. Just label them with red mark by hitting "6" and then sort by label. Then copy all the images and paste them into subfolder "Images No Duplicates".
