Secrets of Timeline(s) in Captivate – Intro
Happy New Year 2017 to all Captivate users!
Quite a while ago I wrote an article about Timeline secrets in Captivate 5: Tiny Timeline Tidbits
Since the change in the UI with Captivate 8 , the newbie User Interface minimizes the Timeline panel by default which is really a pity (personal opinion). Some of the questions I read, at least partially due to that decision to hide the Timeline:
- ‘I want to get rid of the timeline, don’t need it at all‘
(user thinking that Captivate is just a Powerpoint clone).
- ‘Why is the timeline not showing the whole project, so user unfriendly’
(user supposing Captivate is a mini video application)
- ‘Why do I see all the objects on the slide, even when the playhead is in a part where some objects shouldn’t be visible, not intuitive’
(user with an Animation background)
For those reasons I suspect it is Time to update that old article, to explain the ins and outs of the Timeline panel including features like CPVC-projects and slides, Effect Timelines, Drag&Drop, which were added in more recent versions.
Timeline panel, in collaboration with the Timing Properties panel is at the core of the Captivate application(s). Personally I’m persuaded that it should be a top priority in the skills-set of any Captivate developer, whatever its level.
Since I cannot offer you a ‘digestive’ (limoncello, grappa, schnapps, single malt…) I will split up this (broad) subject in several articles. You are reading the introduction. Following posts will treat the topics: ‘Timeline in a cpvc-project’, ‘Timelines in a cptx-project (master slides and normal slides)’, ‘Color coding and Shortcut keys for Timelines’, ‘Why/how to pause a timeline?’.
Why do you need a Timeline?
Many users talk about the output of a Captivate project as ‘a movie’. Although this is only completely true for a file published to a video format (MP4), this indicates well that Captivate is related to video applications like Premiere Pro and After Effects.
No one will have doubts about the importance of ‘time’ for video. A movie has a playhead, which moves at a certain speed. That speed is usually indicated by the term ‘frames per second’, or FPS.
Frames remind me always of the traditional way of producing cartoon movies: each frame, drawn by a graphic artist, was slightly different from the previous and the next frame. By playing those frames at a certain speed, movement could be simulated: the slowness of our eye/brain made it possible to see fluid movements from those frames.
If you prefer watching an interactive Captivate (slide) tutorial instead of reading static text click on this link. This portal only allows passive media until now (image, audio, video).
The detailed screenshots below are taken from these two timelines, the upper timeline is from a cptx-project (slide-based) and the lower timeline is from a cpvc project.
Some items are available in all Timeline panels, for both cptx- and cpvc- projects:
- Contrary to some video or animation applications, the Timeline ruler in Captivate is always in Time units (seconds), cannot be changed to frames (look at the horizontal ruler in the top of the Timeline panel). The smallest increment in the timeline is 0,1 seconds. With a default rate of 30FPS (which can be changed) 0,1seconds = 3 frames.
- The Playhead is represented by a red rectangle. When you use the play button in the control panel (see 4), you’ll see its movements. You can also drag the Playhead to a certain position on the timeline. There is a slight difference in size for the playhead in the cptx project (upper screenshot) and the cpvc project (rectangle is smaller).
- In the first column of the panel, on top you’ll see the Eye button, and each track (horizontal line in the panel) in the Timeline has a dot (blue stroke, orange fill) under this button. Look at the detailed screenshots. When clicking the Eye button on top, all objects in all tracks will be hidden on the stage. This is only meant for editing reasons, will not affect the published file. To hide objects in the published file you need to use a similar eye button situated in the Properties panel of that object. Then meaning of that Properties Eye button is ‘Hidden in Output’. When clicking on a dot under the Eye button, the objects on that track will be hidden. In the example on the screenshot, the second track from the top has been hidden in both the cpvc and the cptx project, a red cross sign indicates the hidden tracks:
- Next to the Eye button is a Lock button, with similar dots for each track. When you click the button at the top, all objects on all tracks will be fully locked. Fully locked means not available for selection, nor for editing any property.
However, if you click a dot next to a track, there are two states. The first state is activated after the first click: it will lock only size and position, but you can still select and change the other object properties. In the screenshot for the cpvc project, the Objects track just above the Video/Audio track is in that state. Look at the arrow indicators around the Lock symbol. Same for the uppermost track in the cptx-project (Highlight box). Clicking a dot twice results in fully locking, no selection is possible, no editing of any property. This is the case for the top track in the cpvc-project, and for the Zoom object in the cptx-project. Watch the look of the lock icon.
- The Control panel at the bottom of the first column (see screenshot below) has the classical (video) buttons, from left to right: ‘Move Playhead to start‘, ‘Stop‘, ‘Play‘, ‘Move Playhead to the end‘. Play and Stop can also be activated with the space bar if the timeline panel is active.
Warning: Play Slide under the button Preview has the same function as Play in this control panel. Although it is under the Preview button it is NOT a preview at all! It is just meant to be used for editing, will not show how the slide will look after publishing. This is a common misunderstanding.The last button on the control panel: ‘Audio‘ is a toggle, will mute/unmute Audio when watching using the Play button. Like the Eye button, this will not affect audio when publishing. The state of this button will apply to all open projects. You see the muted state of that button in the screenshot for the cptx-project.
- In the second column at the same vertical position as the control panel described under 6 and the horizontal scrollbar, you’ll find 4 tiny icons in all normal slides (they have no sense for the Master slide which has no real duration)
- Hourglass icon: indicates the location of the playhead from the start of the track; its tooltip is ‘Elapsed Time‘; this indicator is always available, even when no track nor object is selected.
- Vertical line + right arrow (Selected Start Time) will only have a value when a video clip or a static object is selected; it will indicate the start time of the selected video/object
- Vertical line + right arrow + vertical line (Selected duration) will show the duration of the selected clip/object, is only available when a video/object is selected on a track
- Chrono icon: Total duration of the slide
The Zoom slider to the right of this total duration, allows the timeline to zoom in/out.
