Happy New Year 2017 to all Captivate users!
Quite a few years 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 a pity IMO. 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 with its latest additions like CPVC-projects and slides, Effect Timelines, Drag&Drop.
Timeline panel, in collaboration with the Timing Properties panel is at the core of the Captivate applications. Personally I'm persuaded that it should be a top priority in the skillset 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 topics like '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 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.
You can either read the following text, or watch this interactive Captivate slide:
- 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. The size of the rectangle is bit different between a cptx and a cpvc project as you can see in the screenshot.
- In the first column of the panel, on top you find the Eye button, and each track (horizontal line in the panel) in the Timeline has a (blue, filled with orange) dot under this button. See the screenshots:
- Next to the Eye button is a Lock button, also with dots next to each track. When you click the button itself all objects on all tracks will be locked: not available for selection nor for editing properties. However, if you click a dot next to a track, there are two states. On the first click only size and position will be locked. In that state you can still select /style the objects. The blue Lock icon is surrounded by 4 arrows, as you can see in the screenshot: for the cpvc it is the track immediately above the Video/Audio track, for the cptx project the uppermost timeline. Clicking twice on a dot results in full lock: no selecting/editing is possible. This is the case for the uppermost Objects track in the cpvc-screenshot and for the image I_topics in the cptx project. Watch the different look of the lock icons.
- The Control panel at the bottom of the first column (see screenshot above) has the classical (video) buttons: '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.
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.
- 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. In the screenshot the Smartshape on top is selected.
- 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.
