Video Delogo Tool

Overview

• Drop a video, then draw a rectangle over the target/logo area to generate an ffmpeg delogo filter.
• delogo works by blending/repairing pixels inside the rectangle using the surrounding area, which can “paint over” a static logo (results vary by content, motion, and background).
• Optional: set Start/Stop from the current playback time to process only a middle section via ffmpeg segmentation + concat.
• Click the generated command to copy it, then paste and run it in a terminal (Command Prompt, PowerShell, or macOS/Linux shell) on a machine with ffmpeg installed.

FAQ

• Why does Draw Mode hide controls? To prevent the paused control bar from blocking visibility near the bottom of the video.
• Why does segment mode use -c copy? Splitting and concatenating are faster when streams are copied (no re-encode) for those steps.
• Why does the delogo step re-encode? The delogo filter modifies pixels, so the video must be re-encoded (audio is still stream-copied here).
• Why don’t my segment start/end times match exactly? When using stream copy (-c copy), ffmpeg often can only cut cleanly on keyframes (full “reference” frames). If your chosen time falls between keyframes, the actual cut may snap to the nearest keyframe, so boundaries can be slightly early/late.
• What does “Cleanup intermediate files” do? It appends a best-effort delete step for SEGMENT*.mp4, SEGMENT*_logo_removed.mp4, and CONCAT_SEGMENTS.txt.

Example (segment in the middle of a clip)

• Input file: MyVideo.mp4
• Start: 0:01:30 (1:30)
• Stop: 0:02:30 (2:30)
• Drawn logo box (example): delogo=740:962:416:44

This produces three segments:

• SEGMENT00.mp4 = before start
• SEGMENT01.mp4 = the middle range (start → stop) to be logo-removed
• SEGMENT02.mp4 = after stop

Generated command shape:

ffmpeg -i "MyVideo.mp4" -map 0 -c copy -f segment -segment_times 0:01:30,0:02:30 SEGMENT%02d.mp4 \
&& ffmpeg -i "SEGMENT01.mp4" -map 0 -c copy -c:v libx264 -crf 20 -vf delogo=740:962:416:44 "SEGMENT01_logo_removed.mp4" \
&& echo "file 'SEGMENT00.mp4'" > CONCAT_SEGMENTS.txt \
&& echo "file 'SEGMENT01_logo_removed.mp4'" >> CONCAT_SEGMENTS.txt \
&& echo "file 'SEGMENT02.mp4'" >> CONCAT_SEGMENTS.txt \
&& ffmpeg -f concat -i CONCAT_SEGMENTS.txt -c copy -map 0 "MyVideo_logo_removed.mp4"

What the flags mean (quick)

• -i ...: input file.
• -map 0: include all streams from input (video, audio, subtitles, etc.).
• -c copy: stream copy (no re-encode) for fast split/concat; still overridden for video re-encode in the delogo step.
• -f segment -segment_times A,B: split into numbered outputs at the given timestamps.
• -c:v libx264 -crf 20: encode video with H.264 at a constant quality target (lower CRF = higher quality).
• -vf delogo=X:Y:W:H: apply the logo removal filter using the drawn rectangle.
• -f concat -i CONCAT_SEGMENTS.txt: concatenate the listed files back together.
