Subtitle Removal
Removes hardcoded/burned-in subtitles from videos using OCR detection and AI inpainting.
When to Use
Use this skill when:
- Removing hardcoded subtitles from videos
- Cleaning up videos with burned-in text
- Preparing videos for re-subtitling
- Removing unwanted text overlays
- Cleaning videos for repurposing
How It Works
- OCR Detection: AI detects subtitle regions using optical character recognition
- Region Masking: Identifies areas containing text
- AI Inpainting: Fills removed areas with reconstructed background content
- Output Generation: Produces clean video without subtitles
Workflow
Step 1: Get Source Video
Obtain the video URL with hardcoded subtitles.
Step 2: Submit Removal Task
Call submitAideoTask with:
- prompt: Request subtitle removal
- multiInputs: Array containing source video URL
Step 3: Poll for Results
- First check: Wait 210 seconds after submission
- Subsequent checks: Wait 30 seconds between polls
- Call
getAideoTaskStatus to check progress
Step 4: Timeout Handling
Maximum wait time: 20 minutes
If task exceeds 20 minutes, report as timeout failure.
Step 5: Return Results
On completion, return the clean video URL.
Examples
Example 1: Remove Subtitles
User request: "Remove the subtitles from this video"
submitAideoTask:
prompt: "Remove all hardcoded subtitles from this video"
multiInputs: ["video_with_subtitles.mp4"]
Example 2: Clean Video for Re-subtitling
User request: "I want to add my own subtitles, please remove the existing ones"
submitAideoTask:
prompt: "Erase all burned-in subtitles from this video to prepare for new subtitles"
multiInputs: ["original_video.mp4"]
Example 3: Remove Text Overlays
User request: "Clean up this video by removing the text at the bottom"
submitAideoTask:
prompt: "Remove the hardcoded text overlay at the bottom of this video"
multiInputs: ["video_with_text.mp4"]
Important Notes
- Uses OCR to detect subtitle regions automatically
- AI inpainting fills removed areas naturally
- Works best with subtitles on solid or simple backgrounds
- Complex backgrounds may have some artifacts
- Maximum wait time is 20 minutes
- Processing time: ~10 minutes per 1-minute video
