One set may be burned into the video while another is being added by the player or an operating-system caption tool. Identify each source before disabling anything. A viewer may still need the separate accessible track even when a partial translation is already embedded in the picture.
Turn off one layer temporarily
Disable the player’s selectable subtitle track and replay the same moment. If text remains, it may belong to the video image. If another movable caption window remains, inspect system live-caption settings. Restore any needed accessibility feature after the test rather than assuming all visible text serves the same purpose.
Check what the embedded text covers
Burned-in text may translate only selected foreign dialogue or signs, while the separate caption track includes all speech and sound cues. Removing the full track can therefore make the programme harder to follow. If the player allows positioning, moving one layer may be better than losing essential information.
Avoid destructive cropping
Zooming to hide embedded captions can remove picture content and cannot recover the image underneath the text. Seek an authorised clean version or a more suitable presentation if offered. Report the title, language and time when the supplied layers are unreadable together so the provider can understand the exact viewing problem.
