Video Watermark Remover

Remove watermark/logo/text overlays from videos using ffmpeg's delogo filter.

Core Logic

Step 1: Extract sample frames Extract frames at 1-second intervals to locate watermark positions:

for t in 1 2 3 4 5; do
  ffmpeg -y -ss 00:00:0$t -i "$INPUT" -frames:v 1 "/tmp/wm_frame_$t.jpg" 2>/dev/null
done

Step 2: Analyze with vision model Use the image tool to analyze the sample frames. Ask for:

  • Exact watermark positions (which corner/edge)
  • Pixel bounding box: x, y, width, height for a WxH resolution video
  • Whether watermarks are in the same position across all frames (fixed) or move (dynamic)
