It is as simple as:<br /><code><br /> ffmpeg -i in.mp4 -strict -2 -vf "delogo=x=XX:y=YY:w=WW:h=HH:band=9" out.mp4<br /></code><br /> Replace the XX, YY, etc with the location of the logo in pixels, same for WW and HH for the dimensions.<br /> You can make a screenshot of the video and get the parameters from Gimp beforehand. You can expect perfect result when the logo is above sky or other quite homogeneous part of the video, otherwise of course it's noticeable.<br /> Play with the band parameter (specifies the thickness of the fuzzy edge of the rectangle) for the best outcome.</p> </div> <div class="node__links"> <ul class="links inline"><li class="node-readmore"><a href="http://aron.novaak.net/node/427" rel="tag" title="Remove logo or watermark from a video" hreflang="hu">Tovább <span class="visually-hidden">(Remove logo or watermark from a video)</span></a></li><li class="comment-forbidden">A hozzászóláshoz <a href="http://aron.novaak.net/user/register?destination=/comment/reply/node/427/comment_node_blog%23comment-form">regisztráció</a> és <a href="http://aron.novaak.net/user/login?destination=/comment/reply/node/427/comment_node_blog%23comment-form">bejelentkezés</a> szükséges</li></ul></div> </div> </article>Mon, 06 Apr 2015 02:29:31 +0000Novák Áron427 at http://aron.novaak.net
