    Remove Logo / Watermark

    Hello everybody,

    Is there a way to remove logo / watermark from a video using FFMPEG solution or any other program in a command line.

    Thank you in advance

    There are videofilters in ffmpeg & mplayer (delogo)

    grossly simplied cmd line:
    ffmpeg -i inputfile -vf "delogo" out.mpg

    Can set the active "delogo" region of the video frame.
    http://ffmpeg.org/ffmpeg.html#delogo

    Might have to build your ffmpeg or use Jon Severrisson ppa to get video-filters.
    Think the mplayer delogo feature has been around for sometime..

    Does the logo/watermark indicate copyright information, etc?

    @BicyclerBoy: Oh, thanks

    Code:
    ffmpeg -i 4wX5bMF_a_s.mp4 -vf "delogo=x=10:y=100" out.mp4
    
    [delogo @ 0x806ae20] Option w was not set.
    Error initializing filter 'delogo' with args 'x=10:y=100'
    Error opening filters!
    @QIII: it is a website written there

    Post the ffmpeg version..

    Like I said before ? you need a recent ffmpeg build..
    ffmpeg has been replaced (in Ubuntu) by libav project "avconv"

    Your cmd is complaining that w is not set..so set w...

    I'm using this
    ffmpeg version 0.10.4-6:0.10.4-0ubuntu0jon2
    & this cmd is valid syntax:
    ffmpeg -f v4l2 -i /dev/video0 -vf "delogo=x=0:y=0:w=100:h=77:band=10" out.mpg

    My cmd line was just syntactically correct not a useful cmd for you..

    My cmd captures my netbook webcam & delogos it..just rework your command..

    Re: Remove Logo / Watermark

    something like:

    Code:
    $ ffmpeg -i trimmed.mp4 -strict experimental -vf "delogo=x=20:y=350:w=100:h=100:band=100:show=1" outTrimmed.mp4
    Can we make any background color?

    Re: Remove Logo / Watermark

    The :show=1 colour could be fixed..maybe the band value can change it..
    The green colour block is to help you set the x:y:w:h values..

    :show=0 (the default value) replaces logo with pixels interpolated from surroundings..
    :band might work better with values like 2 to 20 & not =100..
