The marq subfilter can be used to display text on a video.


  • marq-marquee <string> : Marquee text to display. Since VLC version 0.9.0 you can use format strings to display meta data and time information default value: VLC
  • marq-x <integer> : X offset from upper left corner. (0.8.6d and prior: This is only if both marq-x and marq-y are positive) default value: 0 (0.8.6d and prior: -1)
  • marq-y <integer> : Y offset from upper left corner. (0.8.6d and prior: This is only if both marq-x and marq-y are positive) default value: 0
  • marq-position <integer> : Marquee position: 0=center, 1=left, 2=right, 4=top, 8=bottom, you can also use combinations of these values, eg 6 = top-right. (0.8.6d and prior: This is only used if marq-x or marq-y are negative) default value: 5
  • marq-opacity <integer> : Marquee opacity. 0 is transparent, 255 is fully opaque. default value: 255
  • marq-color <integer> : Marquee color. Use the decimal value of the HTML color code. default value: 16777215 (0xFFFFFF, white)
  • marq-size <integer> : Font size in pixels. -1 uses the default font size default value: -1
  • marq-timeout <integer> : Number of millitseconds the marquee must remain displayed. 0 means forever. default value: 0
  • marq-refresh <integer> : Number of milliseconds between string updates. This is mainly useful when using meta data or time format string sequences. default value: 1000

Avalabile Format Variables

  • Time related:
    • %Y = year
    • %m = month
    • %d = day
    • %H = hour
    • %M = minute
    • %S = second
  • Meta data related:
    • $a = artist
    • $b = album
    • $c = copyright
    • $d = description
    • $e = encoded by
    • $g = genre
    • $l = language
    • $n = track num
    • $p = now playing
    • $r = rating
    • $s = subtitles language
    • $t = title
    • $u = url
    • $A = date
    • $B = audio bitrate (in kb/s)
    • $C = chapter
    • $D = duration
    • $F = full name with path
    • $I = title
    • $L = time left
    • $N = name
    • $O = audio language
    • $P = position (in %)
    • $R = rate
    • $S = audio sample rate (in kHz)
    • $T = time
    • $U = publisher
    • $V = volume
    • $_ = new line


Example command line use (VLC 2.0.0 and newer):

% vlc --sub-source="marq{marquee=test,color=16776960} somevideo.avi
This example displays yellow test text in the top left corner of video

Example command line use (VLC 0.9.0 - 1.1.13):

% vlc --sub-filter "marq{marquee=\$t (\$P%%),color=16776960}:marq{marquee=%H:%M:%S,position=6}" somevideo.avi
% vlc --sub-filter 'marq{marquee=$t ($P%%),color=16776960}:marq{marquee=%H:%M:%S,position=6}' somevideo.avi
This command line will show the stream's title ($t) and current position ($P) in the upper left corner and the current time in the upper right corner. Note that we have to escape $ characters when running this from command line in UNIX shells (this is why we use \$ instead of $). The second line uses single quotes to delimit the string so we don't need to escape the $ character.
On windows the command line would be:
C:\Program Files\VideoLAN\VLC\>vlc.exe --sub-filter=marq{marquee=$t ($P%%),color=16776960}:marq{marquee=%H:%m%s,position=6} somevideo.avi

Example command line (All versions including VLC 0.8.6d and prior):

% vlc --sub-filter=marq --marq-marquee="Obvious Watermark" --marq-position=0 --marq-size=50 --marq-opacity=25 --marq-color=32768 somevideo.avi
This command will show centered transparent green text. Text sized too large to fit the video window will not appear, and may crash VLC.
