Qt / Qt4 is the default, plain, graphical, interface to VLC, made using the Qt library (linux users may need to have this installed). It is used as the default interface on the Windows and Linux versions of VLC media player from version 0.9.0 and up.

Unless you change the preferences, VLC media player > 0.9.0 will start up in the Qt4 interface, but you can force this by running

vlc -I qt



If Qt4 is not avaliable, it will probably revert to using the rc (console) interface, even if you force it. The most likely reason for this is if Qt4 hasn't been installed, or if it wasn't linked in (using the ./configure). See compiling VLC [1] for information on compiling.

Main interface Description

Menu Bar

Status Bar

The Status Bar has three distinctive portions displaying information.

  • Name label
  • Speed label
  • Time label

Here are the actions you can do on the status bar:

Select Left Click Right Click Middle Click Double Click
Name label Prepare for copy Give focus for arrows selection Copy menu - Word selection
Speed label - - Show fine rate speed adjusting - reset to normal 1.00x speed
Time label - Switch remaining/elasped time Switch remaining/elasped time Switch remaining/elasped time Open the "Go To Time" dialog

Time label

The timeLabel shows mm:ss/nn:tt in the statusBar.

If the time is longer that one hour, it shows hh:mm:ss/ii:nn:tt.

If you click on it, it shows remaining time instead of elapsed time. If you double click on it, it opens the open the GOTOTime dialog in order to skip easily.

If vlc doesn't know the total time, like in avi/http, it shows the elapsed time only, and --:-- instead of total time.

System Tray Icon


Main Slider

The main slider does control the timeline.

When you click somewhere on the timeline, it skips the movie to that place. When you drag the slider of the timeline, it follows the position on the movie.

When you hover it with your mouse, it shows you where it would go if you click.

Sound Slider

The sound slider does control the volume.

When you click somewhere on the soundSlider, it changes the volume. When you click and drag on the soundSlider, it changes the volume too. If you release the click really outside of the volume slider, it will reset to your old value

When you hover it with your mouse, it shows you the volume it would be if you click it.

Sound range

The sound goes from 0% to 200% and can go up to 400%

100% means normal output of the file without amplification. Above 100% means that it may use software amplification, and it could distort sound (it usually doesn't, but it could).
