<h3><a name="Media_Tracks"> </a><a name="_Media_Tracks_"> </a> <a class="twikiLink" href="MediaTrack">Media Tracks</a> </h3>
Internally all media is organized into tracks. Each track extends across time from left to right displaying your media from begining to end.
<p />
There are two kinds of tracks :
<p />
<h4><a name="Video_Tracks"> </a> Video Tracks </h4>
<img src="../../../pub/Cinelerra/CinelerraImages/track_video.png" /><br>
Video tracks represent the timeline of your videos, just as if you layed real photo film on horizontally on a table.
The individual images you see on the track are a sample of what is located at that particular time on the timeline.
<p />
<h4><a name="Audio_Tracks"> </a> Audio Tracks </h4>
<img src="../../../pub/Cinelerra/CinelerraImages/track_audio.png" /><br>
Audio track represent your sound media as an audio waveform, following the film analogy it would be as if you "viewed"  magnetic tape horizontally on your table. 
<p />
<ul>
<li> You can adjust the horizontal and vertical magnification of the tracks, using the <a class="twikiLink" href="ZoomPanelBar">ZoomPanelBar</a>.
</li>
<li> You can adjust the magnification of the audio "waveform" display using the <a class="twikiLink" href="ZoomPanelBar">ZoomPanelBar</a>.
</li>
<li> The controls to the left of the tracks are called the <a class="twikiLink" href="PatchBay">PatchBay</a>, they are used to control the behavior of the tracks.
</li>
</ul>
<p />
<h3><a name="Working_with_Tracks"> </a> Working with Tracks </h3>
<h4><a name="Track_Navigation"> </a> Track Navigation </h4>
Track Navigation involves both getting to a specific track (audio or video) and getting to a certain time in the track. 
<p />
The program window contains many features for navigation and displays the timeline as it is structured in memory
<p />
<ul>
<li> The horizontal scroll bar allows you to scan from across time. 
</li>
<li> The vertical scroll bar allows you to scan across tracks. 
</li>
</ul>
<p />
In addition to the graphical tools, you'll probably more often use the keyboard to navigate. 
<p />
<ul>
<li> Use <strong>PAGE UP</strong> and <strong>PAGE DOWN</strong> to scroll up and down the tracks.
</li>
<li> Use the <strong>LEFT</strong> and <strong>RIGHT</strong> arrows to move across time in small increments. 
</li>
</ul>
<p />
<img src="../../../pub/TWiki/TWikiDocGraphics/tip.gif" border="0" alt="IDEA!" width="16" height="16" />You'll often need to scroll beyond the end of the timeline but scrollbars won't let you do it. Instead use the RIGHT arrow to scroll past the end of timeline.
<p />
<ul>
<li> Use the <strong>HOME</strong> and <strong>END</strong> keys to instantly go to the beginning or end of the timeline.
</li>
</ul>
<p />
<ul>
<li> In <img src="../../../pub/Cinelerra/CinelerraImages/button_bar.png" alt="button_bar.png" /> I-beam mode, hold down <strong>shift</strong> while pressing <strong>HOME</strong> or <strong>END</strong> to select the region of the timeline between the <a class="twikiLink" href="InsertionPoint">InsertionPoint</a> and the key pressed.
</li>
</ul>
<p />
<h4><a name="The_Track_Popup_Menu"> </a> The Track Popup Menu </h4>
Each Track has a popup menu. To activate the Track Popup Menu, <strong>RIGHT</strong> click on the track ( <em>The popup menu affects the track whether it's <a class="twikiLink" href="PatchBay">armed</a> on the <a class="twikiLink" href="PatchBay">PatchBay</a> or not._</em> )
<p />
The Track Menu contains a number of options for dealing with multiple tracks simultaneously.
<ul>
<li> Attach Effect
</li>
<li> Move up moves the selected track up in the stack.
</li>
<li> Move down moves the selected track down in the stack. 
</li>
<li> Delete track removes the track from the program
</li>
<li> Add Track  adds a track of the same media type (audio/video) as the one selected.
</li>
<li> Resize Track <a class="twikiLink" href="ResizeTrack">resizes the track</a>
</li>
<li> Match Output Size <a class="twikiLink" href="ResizeTrack">resizes the track</a> to match the current output size
</li>
</ul>
<p />
<a name="CreatingTracks"></a>
<h4><a name="Creating_New_Tracks"> </a> Creating New Tracks </h4>
When you create a new project, it contains a certain mumber of <a class="twikiLink" href="NewProject">default tracks</a>. You can still add tracks from a number of menus.
<p />
The <a class="twikiLink" href="AudioMenu">Audio</a> and <a class="twikiLink" href="VideoMenu">Video</a> menus each contain an option to add a track of their specific type. 
<ul>
<li> Audio tracks are put on the <code><b>bottom</b></code> of the timeline and the output channel of the audio track is incremented by one. 
</li>
<li> Video tracks are put on the <code><b>top</b></code> of the timeline. 
</li>
<li> New video tracks are overlayed on <code><b>top</b></code> of old tracks. 
</li>
</ul>
<p />
This way, video has a natural compositing order. 
<a name="ConcatenatingTracks"></a>
<h4><a name="Concatenating_to_a_Track"> </a> Concatenating to a Track </h4>
Concatenate tracks takes every <a class="twikiLink" href="PatchBay">playable</a> track and concatenates it to the end of the first <a class="twikiLink" href="PatchBay">armed</a> tracks.
<ul>
<li> If there are two <strong>armed</strong> tracks followed by two <strong>playable</strong> tracks, the concatenate operation puts the two playable tracks after the two <a class="twikiLink" href="PatchBay">armed</a> tracks. 
</li>
<li> If there are three playable tracks instead, two tracks are put after the <a class="twikiLink" href="PatchBay">armed</a> tracks and a third track is put on the end of the first armed track.
</li>
<li> The destination track wraps around until all the playable tracks are concatenated.
</li>
</ul>
<a name="DeletingTracks"></a>
<h4><a name="Deleting_Tracks"> </a> Deleting Tracks </h4>
Delete tracks deletes the armed tracks.
Delete last track deletes the last track, whether it's <a class="twikiLink" href="PatchBay">armed</a> or not. Holding down the d key quickly deletes all the tracks.
<p />
<p />
<h4><a name="Other_Notes"> </a><a name="_Other_Notes"> </a> <img src="../../../pub/TWiki/TWikiDocGraphics/warning.gif" border="0" alt="ALERT!" width="16" height="16" /> Other Notes </h4>
Operations in the Tracks menu affect only tracks which are <strong>armed</strong> on the <a class="twikiLink" href="PatchBay">PatchBay</a>.
<ul>
<li> <img src="http://www.ftconsult.com/twiki/pub/Cinelerra/TrackControl/program_track_toggles_arm.png" alt="program_track_toggles_arm.png" /> <strong><em>PatchBay with armed track</em></strong>
</li>
</ul>
