Remove Bilingual Subtitles from a Video
Bilingual subtitles commonly use two stacked lines, different scripts, colored speaker labels, or separate positions above and below the safe area. Their combined footprint can be much taller than a single caption band.
For localization, preserve the transcript and meaning before visual cleanup. Removing accessibility or translation text without a replacement can make the video unusable for its audience.
Confirm that both lines are actually burned in
Try the player’s subtitle menu and inspect available tracks. If the text can be switched off, use the container or project workflow; it is lossless and preserves every picture pixel.
If both lines remain visible with subtitles disabled, they are part of the image. Note speaker names, outlines, shadows, and any top-positioned translations that require separate regions.
Avoid one oversized permanent band
Map the maximum footprint for each layout, then split ranges when the number of lines or vertical position changes. A huge mask active throughout the clip can erase faces, products, and lower-frame detail unnecessarily.
Test shots with hands, mouths, patterned clothing, camera movement, and scene cuts. These are the frames most likely to reveal a synthetic strip.
Prepare the replacement localization
Save the original language text, timing, speaker labels, and accessibility cues before removal. Build the new subtitle track from verified transcription or translation rather than trying to read generated pixels.
Review the clean master before adding new captions. Fix visible seams first; otherwise the replacement subtitles may hide defects that return in a later language or layout.
Recommended workflow
- Check whether each language is a selectable subtitle track.
- Preserve transcripts, timing, and accessibility information.
- Map every two-line and single-line layout by time.
- Process the smallest authorized burned-in regions and preview hard shots.
- QA the clean master before adding verified replacement subtitles.
Document the finished edit
Keep the untouched source, the mask or decision notes, and the approved export together. Record why the edit was authorized, which time ranges changed, and which source-first options were checked. For this page, the intended task is: Transactional: remove two stacked burned-in subtitle languages before authorized relocalization.
Before delivery, verify duration, aspect ratio, audio sync, and every repaired boundary in the actual viewing environment. Note that Wipe AI accepts MP4, MOV, WebM, AVI, and MKV, then exports H.264 MP4 up to 1080p. It processes one video at a time, results depend on motion and background complexity, and the output may be re-encoded.
Frequently asked questions
Can soft bilingual subtitles be removed without AI?
Yes. If they are selectable tracks, disable or remove those tracks instead of changing the picture.
Should both burned-in lines use one mask?
Only when their combined footprint is stable. Split ranges or regions when layouts change.
Can the original letters be recovered as text?
Not by inpainting. Preserve or transcribe the source before visual removal.
What file comes back?
Wipe AI outputs H.264 MP4 up to 1080p.
