<title>File properties</title>

<para>Starting from &kplayer; 0.5 each file and <acronym>URL</acronym> has its
own set of properties. They include information that &kplayer; found out about
the file, like time length, video size, frame rate, bitrates, and so on, as well
as various options you can set, like name, video aspect, subtitles, and many
more.</para>

<para>Most properties can be set through the <link linkend="properties">File
Properties dialog</link>. The <guilabel>Properties</guilabel> dialog for the
currently loaded file or <acronym>URL</acronym> can be opened from the
<link linkend="menu-file"><guimenu>File</guimenu></link> menu, or using the
<guibutton>Properties</guibutton> button on the
<link linkend="toolbar-main">main toolbar</link>, or from the <link
linkend="popup-main">right click popup menu</link>. You can also open the
<guilabel>Properties</guilabel> dialog for an entry in the
<link linkend="parts-library"><interface>multimedia library</interface></link>
by <mousebutton>right</mousebutton> clicking it and selecting
<guimenuitem>Properties...</guimenuitem>, or by using the
<guimenuitem>Properties...</guimenuitem> command on the
<link linkend="menu-library"><guimenu>Library</guimenu> menu</link>.</para>

<para>An easier way to set file properties is by holding the &Shift; key
when changing a setting. For example, if you hold &Shift; and select
<guimenuitem>Soft Frame Dropping</guimenuitem> from the
<guimenu>Player</guimenu> menu, &kplayer; will remember that setting for
the current <acronym>URL</acronym>, and use it the next time you play it.
After it is done playing the current <acronym>URL</acronym>, it will revert
the <guilabel>Frame drop</guilabel> setting to the default, the one that
was in effect before you changed it with &Shift;. On the other hand, if you
change the <guilabel>Frame drop</guilabel> setting without holding &Shift;,
the new setting will become the default, and will be used for all
<acronym>URL</acronym>s that do not have it set explicitly.</para>

<para>Volume, contrast, brightness, hue and saturation are handled in a
special way when it comes to file properties. Instead of remembering the
exact setting when you hold &Shift;, &kplayer; will remember the setting
relatively to the default.</para>

<para>For example, if you have a file that was recorded louder than your
other files, when playing that file you can hold &Shift; and adjust the
volume level to be the same as for other files. &kplayer; will remember
this as something like <quote>lower the volume by 10 units when playing
this file</quote>. If later you for example have a party and need to play
your files louder than usual, you turn the volume up (without holding &Shift;),
so all files play louder, then when the turn of that one file comes, &kplayer;
will lower the volume by 10 units while playing it, so it again has the same
volume level as the other files, and then turn the volume 10 units up when
it moves to the next file.</para>

<para>Another example, you find a video that is dark and so needs to be
played with higher brightness than other videos. So you hold the &Shift;
key and drag the brightness slider up. &kplayer; remembers the higher
brightness for this file, and then goes back to playing at normal brightness
when you play another file. Suppose you did that at night, and next time you
play the videos during daylight, so you want to play all of them at higher
brightness. Then you drag the brightness slider up, this time without holding
&Shift;, so the setting is made the default and applied to all videos that do
not have a brightness property set. When the turn of the dark video comes,
&kplayer; sees that it needs to be played at an even higher brightness and
turns it further up, but only for the duration of that one video, and then
restores it back to the default you set.</para>

<para>Choosing the <guimenuitem>Full Screen</guimenuitem> command or clicking
the <guibutton>Maximize</guibutton> or <guibutton>Restore</guibutton> button
in the <link linkend="parts-title-bar">title bar</link> while holding &Shift;
will set the <guilabel>Full screen</guilabel> property. Choosing an aspect
command with &Shift; will set the <guilabel>Display size</guilabel> property
to <guilabel>set aspect</guilabel> and the aspect you choose, and also will
set the <guilabel>Maintain aspect</guilabel> property. A zooming command on
the <guimenu>View</guimenu> menu when chosen with &Shift; will set the
<guilabel>Display size</guilabel> property to <guilabel>set size</guilabel>
and the fixed size, and so will resizing the window if you press &Shift;
before you begin resizing the window.</para>

<para>This special function of the &Shift; key can be turned off on the
<link linkend="settings-controls">Controls page</link> in <guilabel>&kplayer;
Settings</guilabel>.</para>

<para>There are two special cases when you can also hold &Shift; to modify
&kplayer; behavior. First, you can hold &Shift; when telling it to play a file
or <acronym>URL</acronym> or dropping files onto &kplayer; window. &kplayer;
will then load the first file or <acronym>URL</acronym> but will not start
playing it. You can then open its <guilabel>File Properties</guilabel> and make
your choices before starting to play it.</para>

<para>Second, if you hold &Shift; when choosing the
<guimenuitem>Play</guimenuitem> command from the <guimenu>Player</guimenu>
menu or clicking the <guibutton>Play</guibutton> button, &kplayer; will
first stop the helper process that it runs once for each file to try and
figure out the time length of the file. This is needed rarely if ever, only
when the helper process causes any problems.</para>

<para>&kplayer; will remember properties for every file or
<acronym>URL</acronym> that it opens, even those that are removed from the
playlist, until the total number reaches the limit set on the
<link linkend="settings-general"><guilabel>General</guilabel> page</link> in
<guilabel>&kplayer; Settings</guilabel> under <guilabel>Meta information cache
size limit</guilabel>, by default 10000. After that it will start discarding the
oldest entries. Playing an entry makes it the most recent entry in the cache. If
you have very many files, you can set the cache size limit higher, but as some
point it may start affecting &kplayer; performance.</para>

<para>Following are the available file properties, listed by pages in the
