Pausing Captivate's Timeline


This is the fourth post in a sequence of 5. The first post introduced features of all timelines, the second is focused on the specific aspects of the Video Demo Timeline, the third on the aspects of the normal/responsive projects (cptx) both for master slides and normal slides. To understand this article - perhaps the most important - I recommend to  read at least the first and the third article as a preparation. 

This topic is more suited for a live event: a real or a virtual training session. I expect a lot of questions, and those are easier to answer in a live event. I have presented several webinars for Adobe in the past (most about advanced and shared actions), but that practice seems to be discontinued since a while. If you want to participate in a meeting (Connect room), I'm prepared to organize it. Send me a note: either by mail (, in the comments on this post, or use Twitter (my handle is @Lilybiri). In case of sufficient requests, I'll propose a date/hour (probably am PT, for users in USA) and will need an e-mail address for the invitations. As a bonus, will offer you some files.

Pause and Pausing points

Pausing the timeline means stopping the Playhead. However that can be done in in two ways, and they do not affect the items in the same way. Let me first explain what I mean by 'Pause' as opposed to 'Pausing Point'. You'll see that I compare them with two traffic signs: Pause with the red light, Pausing point with the Stop sign. But also in traffic, some 'items' do not respect those signs, legally or illegally. 


This strict way of pausing can be achieved by one of these methods:

  1. With the pause button on one of the default playbars.

  2. By choosing the command 'Pause' to be triggered On Enter for a slide (doing it On Exit is not a good idea, because it will happen after the last frame, see previous post about events).  It can also be a (last) command in an advanced/shared action.

  3. By using the Success event an interactive object (like a shape button) with the command 'Pause' either as a simple command or within an advanced/shared actions. Usually it will be the last command. 

  4.  Alternative for 'Pause' command is to assign 1 to the system variable cpCmndPause (its default value is 0). This system variable controls the pause.

If you use a playbar, you'll see that the progress bar is stuck when Pause is encountered. To understand even better, I recommend to insert the system variable cpInfoCurrentFrame in a text container, displayed for the whole project (on top). 


You can use the Play button on the playbar, or need the command Continue, which is available as simple action and in the dropdown list in advanced actions.

Pausing point

Pausing points exist on some special slides, or you can add them by inserting an interactive object for which Pause the slide is activated in the Timing Properties panel. In many cases the pausing point will be visible on the Timeline (see previous articles), but not always. Contrary to the absolute pause, here the timeline is 'waiting' for an action by the user. For that reason the STOP sign is a better metaphor than the red light. Here is an overview of the pausing points, which will be visible on the Timeline:
  1. Quiz or question slides: the pausing point is visible on the slide timeline, but not in the Timing Properties panel. Only way to move is by dragging. Default timing is at 1,5secs, and pause cannot be unchecked. Pausing point is linked with the two-step process triggered by the Submit button. However when selecting the Submit button, you'll not see the pause in the Timing Properties panel (as is the case for the D&D Submit button). Waiting is here for the user to click the Submit button, then to press Y or click on the slide
  2. Score slide: same situation as for the quiz slides: visible in the slide timeline, not in the Timing Properties. Default timing is at 1,5secs. Pausing point is linked with the Continue button, but will not show in the Timing Properties panel of that button. Waiting here is for the user to click the Continue button.

  3. Drag&Drop slide: is pausing at 1,5secs but the point is not visible on the timeline. You will not see it in the Timing Properties for the slide, but in the Actions tab of the D&D panel. It is linked with the Submit button, when selecting that button the Timing properties panel will show the timing of the pausing point. Waiting for the user to click the Submit button, or in case of Auto Submit waiting for a correct answer.

  4. Interactive objects (click box, button, shape button, Text Entry Box) can have a pausing point, to be defined in the Timing Properties panel. That pausing point will be visible in the Timeline, and the part before the point is indicated as 'Active', part after the pausing point as 'Inactive'. Since a click box is invisible to the user, it has not inactive part, its pausing point will always be at the end of its timeline. Waiting is for the user to click either on or outside of the interactive object (click box, shape or normal button) or to confirm the Entry in a TEB. You can edit the pausing point by dragging in the Timeline or in a precise way by editing the Timing Properties panel. It is also possible to uncheck the Pause (see screenshot 3 in the Gallery).

  5. Shape button on a master slide can have a pausing point. Since objects on a master slide have no duration, no Timing Properties panel, you have to indicate that you want it to pause, in the Actions tab of the Properties panel (see screenshot 4 in the Gallery). You can uncheck the pause there as well. The pausing point will be at the end of each slide, based on that master slide. It will not be visible in the timeline
  6. Interactive widgets or learning interactions have a pausing point at 1 sec. It will not show up in the Timeline, you can find it in the Timing Properties.  Pause can be unchecked, but you'll not want to do that for this type of interactions.That is the place to edit or uncheck the Pause (see screenshot 5 in the Gallery). Static widgets/interactions do not have a pausing point. More info about difference  between interactive and static in: Widgets and Interactions

Bonus: You can download a (watermarked) pdf with this overview from PausingPoints.


It depends on the kind of pausing point:

  1. For Question slides: the playhead is released after the second step of the Submit process and the actions defined in Question properties will be done.

  2. For Score slide: similar, but after clicking the Continue button.

  3. For Drag&Drop: exactly the same as for the Question slides, after clicking the Submit button.

  4. For interactive objects on master or normal slides: if an advanced action is executed (Success/failure) the playhead is not released automatically. If you want this to happen you have to include a Continue or a navigation command like Jump to as last command in the action. If you use a simple action, the playhead will be released by default, but in CP9 it is possible to uncheck that default setting 'Continue playing the Project' (not done in this screenshot).

What is Paused?

Not everything is paused by the absolute Pause command, nor the Pausing points. Watch the interactive movie to understand better. Some items are never paused, some are paused by both Pausing points and the Pause command, some are only paused by the Pause command, not by the pausing points although there may be a workaround. 

The position of the playhead when pausing is important: objects for which the object timeline starts later than the pause will not appear until the playhead is released.

Same is the case for Effects which have a duration, a timeline: if the pause occurs while the effect is not finished, it will stall in the last position and continue only when the playhead is released.

Animations however are never paused, not even when you use the Pause command triggered by the On Enter event of a slide. They will always play.

Video clips inserted as Event video are totally independent: if they are playing when pausing, they'll continue to play. If a pause is occurring and the video is not yet started, the user will be able to use the Play button of the video control panel to watch the video. Video clips inserted as Multisynchronized video however will be paused by the Pause command and by a pausing point.

The situation is a lot more complicated for audio:

  • Background audio is totally insensitive to Pauses or Pausing points: it will continue to play.

  • Slide Audio: will automatically be paused by the Pause command, but not by a pausing point. It is possible to pause slide audio at a pausing point, to resume when the playhead is released if you check 'Stop Slide Audio' on the Options tab in the Properties panel of the interactive object.
  • For the default pausing points on quiz slides, score slide, D&D slides you cannot pause the slide audio however. This seems confusing, and can lead to a problem. Slide audio clips automatically will increase the duration of the slide. You learned that the default pausing point of this type of slides is always set to 1,5seconds. If the playhead is released with the command 'Continue', it will have to visit all the remaining frames on the slide, those frames in the 'big' inactive part of the slide. To avoid that, I recommend that you change the default pausing time and make it just a little bit smaller than the slide duration. This is not necessary if the actions when releasing the playhead from its pausing point are a navigation to another slide, because the inactive part of the slide will just be skipped.

  • Object audio: will be paused by the strict command Pause, but not by a pausing point! There is no workaround for this behavior for a Pausing point.

  • Audio started with 'Play Audio' cannot be stopped not by Pause nor by a pausing point, the only way to stop it is by launching the command 'Stop Triggered Audio'. 

Why pausing?

This blog post has become very long, for which I apologize. For that reason I will write out some use cases, to illustrate the just described theory in later posts. You're welcome to post some ideas as well. Here are some appetizers:

  • Instead of creating very long slides to fit the narrations, use the Play Audio command and have a pausing point on the slide. That can be a Next button, which offers total control to the user.

  • Question slides with narration as slide audio: you need to move the pausing point.

  • Create custom navigation: use shape buttons on the main master slide, only one of them needs a pausing point to give each user all the time needed to watch the slides.

  • Create a slide with light boxes.

  • Have multiple TEB's on one slide with a unique Submit button.

  • Create a dashboard with buttons to display multiple vodcasts, images, podcasts.

Knowledge Check Slides - tips


Knowledge Check Slides have been introduced as one of the new quizzing features with version 9. The Help documentation is 'spartan' as usual. You can read this as Features (quote from the Help):

  • Knowledge check slide imbibes similar features of question slide without any results, reporting structure and interaction ids. 
  • Knowledge check slides do not participate in reviews. 
  • Random questions are not applicable to this knowledge check slide. 
  • Master slide and controls usage is similar to question slide. 
  • Knowledge check slides can be used to impart the learning on specific topics. 

I explored those KC slides in preparation for a workshop about new Quizzing features, and want to give you some more tips. Since the KC slides are very similar to normal quiz slides, I'll start with 'Recognizing KC slides'. Then I'll show the differences in default setup, and in some other aspects not mentioned in the Help,  the relationship with the quizzing system variables and - what did you expect? - a tweaking tip.

Recognizing KC slides

This is possible in different locations:
  • in the Filmstrip, KC slides get a special indicator at the bottom right, which the Quiz slides do not have; in this screenshot slides 1&3 are KC slides and have that indicator:
  • in the Quiz Properties panel you see more differences with normal quiz slides, most are due to the fact that KC slides are not scored by default:
  • The mention (KC) next to the type of question
    The lack of the possibility to choose between Graded and Survey (because KC slides are not scored)
    No partial scoring for MCQ slides with multiple correct answers 
    No points
    No penalty

  • in the Advanced Interaction panel you don't see a specific indicator. The score of the KC slides is set to 0,  they are not set to be reported but... contrary to what the Help tells, the KC slides have an individual Interaction ID. This is probably not used. Look at this screenshot:

There is no way to convert a KC slide into a question slide, nor a question slide into a KC slide!

Default setup KC slide

The default settings for a KC slide are bit different from those for a question slide:

  1. For a KC slide only the Incomplete feedback message is activated, not the Correct message as for Quiz slides
  2. For both KC and Question slide only the Submit button is checked off. The Back, Skip and Clear buttons can be activated, but they are not by default.
  3. Attempts are set to Infinite, with the Retry Message enabled. For question slides by default Attempts is set to 1. Because the attempts are set to infinite, you don't have a Failure message enabled for KC slides. You can decrease the attempts and in that case you can provide up to 3 Failure message, same as for Question slides.

You read in the Help that KC slides will not be visited during Review, they are not in the Quiz scope, except of course if they are nested in between normal quiz slides. Contrary to Pretest slides, the KC slides will not prevent navigation by playbar or TOC.

It is not possible to use question pools (see Help), random questions but it is also not possible to use GIFT format to import KC slides. 

Some options in the Quiz Preferences do work for KC-slides: if you check the option to Hide Playbar in Quiz, this will be valid both for question slides and KC slides. Unchecking the option 'Allow Backwards Movement' will only prevent backwards movement on question slides, not on KC slides. However, KC slides do not get a Progress indicator! IIf you want a progress indicator (question X of Y) you can have a look at this older blog post..

When you leave a KC slide, it is reset immediately which is not the case for question slides which are frozen until a new attempt on Quiz level is started. In that way a KC slide behaves like a Drag&Drop slide that is not set to be reported, had no score. There is no possibility to freeze the answer on a KC slide, which may be a game stopper sometimes.

As the Help mentioned, design of the KC slides depends on the same master slides as the normal question slides, with the exception of the new Review buttons which will never appear on KC slides. For navigation on KC slides you can use the Back/Skip buttons or add custom shape buttons.

System variables 

Contrary to the Pretest slides, there are no specific system variables available for Knowledge Check slides. I have been looking for quizzing system variables that do get a value from a KC slide. Here is an overview of the variables that are not used by KC slides:

  • cpInQuizScope and cpInReviewMode, both Booleans will not be toggled from the default 'false' to 'true' when you enter a KC slide. If the KC slide is in between normal question slides, it can be 'true' but that is not due to the KC slides.
  • Variables linked with scoring are not used: cpInfoPercentage, cpQuizInfoLastSlidePointScored, cpQuizInfoNegativePointsOnCurrentQuestionSlide, cpQuizInfoPassFail, cpQuizInfoPointsPerQuestionSlide, cpQuizInfoPointsscored, cpQuizInfoPartialScoringOn, cpQuizInfoTotalProjectPoints, cpQuizInfoTotalQuizPoints 
  • cpQuizInfoAttempts: gives the attempts on Quiz level, as specified in 'Quiz Preferences, Pass or Fail'. Those attempts have no sense for KC slides, since the user can come back as many times as he wants to retake the KC question which is always reset when leaving the slide.
  • cpQuizInfoPassPercent and cpQuizInfoPassPoints: since KC slides have no score, those settings of the Quiz Preferences have no meaning for KC slides.
  • cpQuizInfoTotalQuestionsPerProject: contrary to the Pretest questions which are counted in this variable, as are the normal Question slides, the KC slides are not included in this variable. Same for the variables cpQuizInfoTotalCorrectAnswers, and cpQuizInfoTotalUnansweredQuestions

As you see not many variables are used by KC slides, but some are used! Moreover they can be very useful if you want to do more with KC slides:

  • cpQuizInfoAnswerChoice: one of my favorites as you could read in this old blog postIt can be used to tweak the work flow with KC slides as you'll read more later on. One exception: it is not populated when you use Advanced Answer option.
  • cpQuizInfoMaxAttemptsOnCurrentQuestion: can be useful as well, although having a similar system variable to cpQuizInfoAttempts for current attempt on question level would be even better. You need a user variable as a counter for attempts on question level. If you keep the default setting of Infinite attempts, this variable will have the value 32767 (no idea why?).
  • cpQuizInfoQuestionSlideTiming and cpQuizInfoQuestionSlideType are available for KC slides as well.

Tweaking tips

Here are some tips, which I tried out with success but will not explain in detail.

  1. If you do not want to keep the Attempts set at Infinite, but to a limited number it would be possible to count the number of correctly answered KC slides. Create a user variable v_counter with a default value of 0. Use the Success action of the KC slides to increment that counter. Later on you can show the obtained value for v_counter, and even use that value in a conditional action to offer feedback or navigate the user back to content slides.

  2. There is no Review possibility for KC slides as mentioned. If you offer limited attempts on question level, you could show a custom feedback message on the KC slide for the questions answered correctly, something like 'You have answered this question correctly'. When simulating a 'Review' situation, the user will be invited to answer only the KC questions that do not show that message. Be careful: all embedded question slide objects are always on top of the stack, you don't want the feedback to be hidden by those objects. That can be done by having a shape before the KC slide, timed for the rest of the project and always on top. This tweaking work flow was described in this article: Buttons on Question/Score slides?

  3. The use case described in this thread of the Captivate forums could be solved using the same system variable cpQuizInfoAnswerChoice in conditional actions, combined with a counter to track the number of attemptsl. You cannot leave a normal question slide to a content slide for remediation unless you follow the strict rules for remediation. If you want to limit the attempts to get a correct answer, remediation rules are broken. With a KC slide, the answers are reset every time, which allows a lot more freedom. However: if you need a real score for the slide, you'll have to use the workaround I described in this blog post: Report Custom Questions - part 2

    System variables in Captivate 8/9


    Captivate 9 users: there is no change about system variables in this version, you can download the same table.

    The post 'System variables in Captivate 6' has been very popular, probably because it offers more details than what can be found in the documentation of Captivate itself. Later on I mentioned some new variables in Captivate 7 in the post New Features in 7.0.1.
    Time to upgrade the table for Captivate 8, you can download (for free) the pdf from here. The document is encrypted to discourage abuse. You will be able to print it at low resolution (150dpi) and it can be read by a screen reader. 

    The table was first proposed at the Adobe Learning Summit presentation about Advanced and Shared Actions. 


    Captivate 8 only added two new variables:

    • cpInfoMobileOS in the category 'System Information': is read-only and detects which device is used, returns a number or a case-sensitive string

    • cpInfoGeoLocation in a new category 'Mobile': returns the geometric location when using a device on which such detection is enabled. This is the first variable that has not one but three components. Latitude, Longitude and Accuracy are numbers. There are several tutorials around, like this one.
