Sequencer Panel

The Sequencer panel enables you to add new sequences into your project. It is possible to sequence most parameters in Nuke Stage.

Tip:  You can middle-mouse drag parameters into the sequencer to check whether they can be sequenced. If they cannot be sequenced, a red overlay with the message Not Animatable will appear. If they can be sequenced, a green overlay will appear with the message Add Track.

The most common use of this feature is to sequence parameters from nodes within any node graph. When a node graph is created, a sequence mirroring the graph is automatically generated.

In these automatically created sequences, every node from the node graph is represented by a parent track. The parameters of each node also have their own tracks. The tracks are visible in the node tree-view on the left of the sequencer. You can choose to hide/ re-open this display by clicking the Show tree view icon ().

The Sequencer can also be used to sequence images, using clips. This enables you to edit and structure content from a Read node. Image clips can be re-timed, repeated, trimmed or re-targeted. Read more about clips at Using Clips.

You can access the sequencer tracks for each node’s parameters from the Sequence workspace tab through the Properties panel.

Sequencer Controls

There are controls in the Sequencer frame that enable you to edit and manage your nodes in the sequencer graph. The below table outlines:

• Sequencer tools, Content tools, State editor and Playback controls. - found on the left side of the sequencer frame.

• Timeline controls - found in the sequencer timeline.

• Property tracks - found when interacting with the tree-view list of tracks.

• Right-click context menu - found by right-clicking in the Sequencer frame. Include many shortcut settings.

• Keyboard shortcuts:

• Ctrl+scroll to zoom in/out. Also works on the timeline. Alternatively use Alt+middle-mouse button drag.

• Middle-mouse drag on the background to pan in frametime, or use horizontal mouse wheel if you have one.

• Left/right arrows to step frametime left and right.

• Alt+left/right to jump to the prev/next cue/keyframe if one is selected.

• F to fit the view to whatever is selected, or to the frame range if there is no selection.

• Ctrl+A to select everything.

• Ctrl+Shift+A to select everything that is visible at the current zoom level.

• L/M/S to toggle lock/mute/solo for the track under the mouse.

• V to cycle curve mode for the track under the mouse.

  Control (UI)	Function
  Sequencer Tools
  Tool selection	Cycle between Multi-tool, Select, Move and Trim. • Multitool - Combines selection, moving and clip trimming. Click on clips, cues, keyframes or track bodies to select them, or click and drag in empty space to marquee select. Click and drag on an object to reposition it in frametime. Click and drag on the start or end of a clip to trim it. • Select - Click on clips, cues, keyframes or track bodies to select them, or click and drag to marquee select. • Move - Click and drag on clips, cues, keyframes or track bodies to reposition them in frametime, or adjust keyframe values. Either frametime or value will be modified, depending on initial direction of the drag: hold Ctrl to allow editing both at once. • Trim - Click and drag on the start or end of a clip to adjust the portion of its overall frame range that will be played. A clip cannot be extended past its maximum frame range, and cannot overlap adjacent clips. The keyboard shortcut for this tool is Q.
  Razor	Click on a clip to split it into two independent clips. Hold Alt to split all clips at the location of the current frametime. Click between: • Razor - Razor the clip you click on. • Razor all - Razor all clips that cover the frametime you click at. If Alt is held in this mode, it will change back to Razor mode. • Razor join - Connect adjacent split clips. Won't work if there is a gap between the clips, or if the clips have different patterns. The keyboard shortcut for this tool is W. Tip:  Click Esc before releasing the mouse to cancel a split/ erase.
  Slip	Click and drag on a clip to shift the contents of a clip forwards or backwards in time, while keeping the clip at the same position in the sequence. The keyboard shortcut for this tool is E.
  Retime	Click and drag on the start or end of a clip to adjust its playback speed. The number of frames used from the sequence will remain constant, but the frametime the clip covers will change. Note:  A clip must be at least one frame long, and cannot overlap adjacent clips. The keyboard shortcut for this tool is R.
  Content Tools
  Add Group track	Select the tracks you want to include with Ctrl+Left-click, or click and drag on the sequence background over the tracks. Press Add Group track to create a new Group track with the selected tracks. Alternatively, select the tracks you want to group and press G.
  Add a property track	Adds an empty new Property track to the tree-view list when clicked. Can also be done with the keyboard shortcut Shift+N. Tip:  A quick alternative is to middle-mouse drag the property you want to animate directly from the Properties panel into the tree-view list.
  Add a label cue	Adds a new Cue at the location of the current frame when clicked. Alternatively, click and hold the location on the desired frametime of the cue sheet (at the top of the sequencer), and press K.
  State Editor
  Snapping	If enabled, keyframes and cues will be snapped to the nearest frame boundary.
  Show empty tracks	If disabled, empty tracks will be hidden in the Sequencer. A keyframed track is considered empty if it contains no keyframes, while a group track is considered empty if it has no child tracks.
  Playback Controls
  Looping enabled	Whether sequences should loop back to the start when finished.
  Auto-follow frametime	If enabled, the timeline will automatically scroll to keep the playback frametime in view.
  Playback speed	The ratio at which playback frametime advances compared to reference frametime.
  Timeline Controls
  Start Frame	Defines the green start frame of the Sequencer. Can be edited by right-clicking the Sequencer where you want the frame, and clicking Timeline > Set range start. Timeline > goto range start to navigate to the start frame.
  End Frame	Defines the red end frame of the Sequencer. Can be edited by right-clicking the Sequencer where you want the frame, and clicking Timeline > Set range end. Timeline > goto range end to navigate to the end frame.
  Current Frame	Defines the orange current frame of the Sequencer. Can be edited by right-clicking the Sequencer where you want the frame, and clicking Timeline > Set current frame. Alternatively, click the current frame and drag it to the desired location on the Timeline. Timeline > goto range end to navigate to the end frame.
  Property Tracks
  Add Keyframe	Click the Keyframe icon () next to the property to add a keyframe at the current frametime. Read Keyframing for the full process.
  Change curve mode	Click to choose from the Curve editor dropdown. Can also be changed in the Properties panel - see Curve editor.
  Mute current track	If enabled, track will not be evaluated. Click the icon () or change in the Properties panel. Note:  Muting a Group will mute all child tracks.
  Solo current track	If enabled on any track, only the soloed tracks will be evaluated. Click the icon () to enable, or change in the Properties panel. Note:  Soloing a Group will also solo all child tracks. Child tracks can be individually soloed when specifically selected.
  Lock track	If enabled, the selected track will be treated as read-only by the sequencer. Click the icon () to enable or change in the Properties panel. Note:  Locking a group will lock all child tracks.
  Group tracks	Ctrl+Left-click to select tracks you want to group. Right-click and select Group tracks. A new track appears in the tree view that contains a copy of the selected tracks.
  Color	Change the color of the track in the timeline view. You can do this by using the Color settings in the track’s Properties panel.
  Right-click context menu
  Add track	Shortcut to create either Property track or Group track.
  Columns	Choose to display the Tool bar of icons in the list of tracks. You can also access this view by clicking the columns icon () at the top-right of the sequencer frame.
  Tools	Choose to enable/ disable the following Tools: • Snapping enabled - when enabled, keyframes can only align with whole frametimes. • Show tree view – show or hide the left-hand track tree view. • Show empty tracks - if disabled, keyframed tracks that contain no keyframes will be hidden, as will groups containing no tracks that would otherwise be shown.
