I can only see these in handbrake, no other tool sees them They are EIA-608 captions and they're part of the video stream. https://en.wikipedia.org/wiki/EIA-608 Apparently the only way to remove them is to re-encode the video and strip them out. https://stackoverflow.com/a/51439554 Can you follow these instructions on you TV and make sure Closed Captions are off or disabled in the TV settings Closed captions and other accessibility settings for your Samsung TV
