- \item[Play Track] determines whether the track is rendered or not. If it is off, the track is not rendered. For example if you turn it off in all the video tracks, the rendered media file will have only audio tracks. If the track is chained to any other tracks by a shared track effect, the other tracks perform all the effects in this shared track, regardless of play status of the shared track that in this particular case affects the media output but not fade and effects.
- \item[Arm Track] determines whether the track is armed or not. Only the armed tracks are affected by editing operations. Make sure you have enough armed destination tracks when you paste or splice material or some tracks in the material will get left out. In addition to restricting editing operations, the armed tracks in combination with the active region determine where material is inserted when loading files. If the files are loaded with one of the insertion strategies which do not delete the existing project, the armed tracks will be used as destination tracks.
- \item[Gang Fader] cause the fader to track the movement of whatever other fader you are adjusting by dragging either the fader or the curve on the track. It doesn't affect the editing made with menu controls. A fader is only ganged if the arm track is also on. This is often used to adjust audio levels on all the tracks simultaneously. Gang also causes Nudge parameters to synchronize across all the ganged tracks.
- \item[Draw Media] determines if picons or waveforms are drawn on the asset in the track. You may want to disable this if you know that the media/format takes a long time to draw on the timeline. By default it is set to on in order to see picons on the timeline.
- \item[Don’t send to output] , more commonly called \textit{mute}, causes the output to be thrown away once the track is completely rendered. This happens whether or not \textit{Play track} is on. For example if you mute all the video tracks, the rendered media file will have a blank video track. Mute track is represented on the timeline with a line that has the default color of pink/orange. Use the pulldown View $\rightarrow$ Mute to have the line displayed. It is a keyframable attribute, but Mute track keyframing is a toggle and it has only the two values of on or off. If a track is part of a shared track effect, the output of the track with the shared track effect is overlaid on the final output even though it is routed back to another track (the shared track). Mute track is used to keep the track with the shared track effect from overlapping the output of the source track (the shared track) where the shared track effect is not present.
- \item[Fader slider] fade values are represented on the timeline with a pink curve that is keyframable. All tracks have a fader, but the units of each fader depend on whether it is audio or video. Audio fade values are in dB. They represent relative levels, where 0 is the unaltered original sound level, -40 is silence, -80 the minimum value set by default. You can move fader and keyframes down to -80 but the parameter's curve won't go below -40. For your convenience you can set a different fade range with the curve zoom. Audio fader’s main purpose is to \textit{fade out} sound or to lower the sound level smoothly to silence, or \textit{fade in} to make sounds appear gradually instead of suddenly. Video fade values are the percentage of opacity of the image in normal overlay mode, the percentage of the layer that is mixed into the render pipeline in the other overlay modes.
- Click and drag the fader to fade the track in and out. If it is ganged to other tracks of the same media type, with the arm option enabled, the other faders should follow. Hold down the Shift key and drag a fader to center it on the original source value (0 for audio, 100 for video).
- \item[mixer] in the expanded patchbay for that track designate the multi-camera mixer mode.
- \item[Overlay mode] in the expanded patchbay is used for porter-duff operations and is full explained in Overlay Modes \ref{cha:???}.
- \item[Nudge] is in the expanded patchbay. The nudge value is the amount the track is shifted left or right during playback. The track is not displayed shifted on the timeline, but it is shifted when it is played back. This is useful for synchronizing audio with video, creating fake stereo, or compensating for an effect which shifts time, all without altering any edits (figure~\ref{fig:overlay}).

- Enter the amount of time to shift to instantly shift the track. Negative numbers make the track play later. Positive numbers make the track play sooner. The nudge units are either seconds or the native units for the track (frames or samples). Select the units by right clicking on the nudge textbox and using the context sensitive menu. Nudge settings are ganged with the Gang faders toggle and the Arm track toggle. Use the mouse wheel over the nudge textbox to increment and decrement the value.
- \item[Pan] is available in the expanded patchbay for audio tracks via a panning box. Position the pointer in the panning box and click/drag to reposition the audio output among the speaker arrangement. The loudness of each speaker is printed on the relative icon during the dragging operation. The panning box uses a special algorithm to try to allow audio to be focused through one speaker or branched between the nearest speakers when more than 2 speakers are used.
