Intro

This short blog post is meant to answer another question on the Adobe forums. It is at the end of this thread:

https://community.adobe.com/t5/captivate-discussions/pausing-slide-audio/td-p/12312792

This was the goal:

1. Slide has narration as slide audio
2. There are multiple shapes used as buttons, which should trigger an audio clip using 'Play Audio' command; those shapes have no pausing point.
3. When a shape button is clicked the audio clip should play, but the slide audio should pause, and resume after the audio clip ends.
4. There is at least one more interactive object pausing the slide towards the end. Idea is that the learner can still listen to the audio clips after the slide audio has finished.

This learner tried to solve this with simple actions, using the feature 'Pause slide audio when clicked'. It cannot be solved that way however.

Example project

Watch this short project created to double-check my proposed workflow with a shared action for the shape buttons. After the Title slide you'll see a slide with a Next button to pause the slide, and a shared action triggered by each of the shape buttons. A copy of the Timeline panel can be found on the third slide. I used some slides from the Aspire Quick Start Project.

You can open a rescalable version using this link or watch the embedded version below:

Setup

You could see the slide audio (narration) in the Timeline panel. The audio clips for the shape buttons were imported to the Project library, and their exact duration was checked, because it will be needed in the shared action. Have a look at the shared action with its two parameters (name audio clip and duration clip):

It has two parameters:

The command Pause in the action will pause the slide audio automatically, contrary to a pausing point of an interactive object. You don't have to change any setting in the shape button Properties. The Continue command which will be done at the end of the audio clip will take care of resuming the slide audio.

Do not bother about having two clips playing at the same time. If the learner clicks another shape button before the first audio clip ends, that first clip is stopped automatically. No need to add a command like 'Stop triggered audio' which is only needed when you want to stop a playing clip without playing a new at the same time.

The user is concerned that applying the shared action will take more time than the approach he tried out with simple actions. However, since you don't have to change settings in the shape button Properties panel, the shared action approach needs even less clicks. Check it out. There is no danger of choking Captivate which could happen if you use duplicate advanced actions since you are using instances of one shared action (ecologically).

Problem

The previous solution works fine until the learner has reached the pausing point of the Next button. At that moment, the Continue command in the shared action will override the pausing and the playhead will continue until it reaches the end of the slide and moves to the next slide. It is necessary to cope with that different situation. The Delay command nor the Continue command take into account possible pausing points. 

There are two different situations, each needing a different workflow:

• Learner clicks a shape button before the narration has ended. In that case the slide audio needs to be paused, and to resume after the end of the triggered audio clip.
• Learner clicks a shape button after the narration has ended. You need to maintain the pause which occurs at the pausing point of the Next button.

This screenshot shows the Timeline panel, illustrating the two situations. Situation 1 in red, situation 2 in blue.

This needs apparently a conditional action for the shape buttons. You have to figure out which situation is valid. For that reason you need to know when the narration has ended. It is easy to see its duration in the timeline, in this case it was 28secs. To calculate the frame number at the end of the frame I used micro-navigation. If you are new to this type of navigation, please have a look at this blog post:

Intro to Micro-navigation

Solution

Variables

You need two user variables:

• v_start: will store the frame number of the first frame of the slide with the narration and shape buttons
• v_stop: will store the frame number at the end of the narration
  

Contrary to the timeline panel where seconds restart on each slide, the frame numbering continues throughout the project.

Shared Actions

EnterSlideAct

This shared action will be triggered with the Slide Enter event, and is meant to calculate the value of v_stop. Have a look:

The first frame number of the slide is stored in v_start. The duration of the narration is converted to frames, by multiplying with the system variable cpInfoFPS. The only parameter is that duration.

PlayAudio_Act

The former standard action has been transformed to a conditional action:

Same parameters as before. The condition checks if the learner clicked the shape button before or after the end of the narration. Only when the narration hadn't been finished it will need to resume. That has been done with the Delay command and Continue. That is not necessary after reaching the end of the narration, because the pausing point of the Next button needs to be kept pausing, and the narration doesn't need to resume.

This shared action is needed for each of the interactive objects used to play an audio clip.  In the project I used shape buttons. They are visible in the timeline screenshot as SB_Topic1…. SB_Topic4.

By using shared actions instead of duplicate advanced actions, you avoid choking the project if you need lot of those actions which was the case for the user asking the question. Moreover multiple instances of the same shared action also will result in a smaller file size. Of course they are also very easy to transfer to future projects.

Intro

Adding audio clip

• Import the audio clips to the project Library
  

  
• Drag the audio clip to the timeline of the slide (or to the stage, be careful not to drag to an object on the stage). Originally the slide timeline on most QSP slides is 3 seconds. If the audio clip is longer, a dialog box will appear. Choose the first option to extend the slide timeline.
  

  
• Audio timeline appears below the slide timeline. I will increase the slide timeline duration manually bit more, so that I’m able to move the audio clip to leave a small gap before and after the audio.
  

  
• You see in previous screenshot that all the object timelines have been extended automatically.  Reason is that most - but not all  - slides in the QSP are timed for the 'Rest of the Slide'. Check Timing Properties. Have also a look at Tip 1 below.
  
  
• Test the audio, not by using Play Slide but by using a real Preview. This means for a non-responsive project that you need to use F11, Preview HTML5 in Browser. For responsive projects any Preview is fine. The three following tips are meant to fix problems detected during previewing.

Tip 1: Fix when objects disappear

In this slide (12 from Aspire) some objects have a timeline keeping the original duration of 3secs. When playing that slide in Preview, those objects will disappear after 3 seconds.

How to fix?

Tip 2: Pause commands on slide events

Many slides in the Aspire project have the setup as shown in this screenshot.

This setup will prevent the audio clip on the slide from playing because the Pause command on the first frame will pause also slide a udio.

You have to take out that pause. You can safely replace it by ‘No action’ which is the default setting both for On Enter and On Exit slide events Result will be that the slide will not be paused, but the playhead will move seamlessly to the next slide when the audio has finished. That is IMO the most logical situation. If you want to mimick a presentation, where each slide is paused at the end and needs learner intervention, you can change the On Exit action to ‘Pause’ or add a button ‘Next’ to pause the slide. However do not forget that this may not be the best practice.

Tip 3: Pausing points

Contrary to the Pause command (see tip 2) a pausing point will not pause slide audio, although the playhead will be paused and so will all graphics assets/effects which are running or appear later.  By default, all pausing points will be set to occur at 1.5secs, either on the slide (for Quiz slides and Drag&Drop), or after the start of the interactive object timeline.

In most cases the increase of the slide duration due to inserting an audio clip will not cause problems, when the pausing point is due to an interactive object like a button. Reason is that the button will often trigger an action jumping to another slide, or revealing some content. The frames after the pausing point (inactive part) are not important in that case.

Possible issues can occur on quiz slides, if you insert an audio clip.  Here is an example (T/F slide 23 in Alliance):

You see the pausing point on the slide timeline at 1.5secs. Some smart shapes are not timed for the rest of the project (see Tip 1). However since the slide is paused at 1.5secs, before the end of those shape timelines, you’ll not be bothered by that while the audio continues playing (not paused). However, if while testing that slide, you have to wait a long time after the Submit process, and you see the shapes disappearing, that is due to the Actions setup in Quiz Properties. They were set in this slide as shown here:

Both actions are set to ‘Continue’, which means that the playhead is released. It will have to move through all frames after the pausing point (inactive part), and only moves to the next quiz slide after reaching the last frame. Not exactly what you want. Two possible fixes:

Fix 1: 

As is the case for other quiz slides in the QSP projects, replace the action ‘Continue’ by ‘Go to Next Slide’. You don’t have to bother about the wrongly timed smart shapes in that case.

Fix 2: 

Move the pausing point on the quiz slide with the mouse (not possible in Timing properties) to place it near the end of the slide. In that case you have to extend the smart shape timelines as explained in Tip 1. This workflow is recommended over the first fix,  if you expect slow connections with the LMS.

Similar problems can occur on Drag&Drop slides but will not expand on that. Know however that the pausing point is not visible on D&D slides in the Timeline panel as is the case for quiz slides.

Pausing Timeline and Audio

Why?

Static and Interactive

It seems logical that Learning Interactions are interactive, because they allow the learner to click and interact, and they are listed under the Interactions big button. Indeed, they all have some of interactions internally. However not all are also ‘Interactive object’ in Capativate’s timeline. A Captivate interactive object can be recognized this way:

• It has an Actions tab
• Under the Actions tab you find up to two events (Success, Last Attempt)
• A pausing point is automatically inserted at 1.5secs.

You know the common interactive objects: button, shape converted to button, Text Entry Box, click box. For those objects you’ll see the pausing point immediately on the slide timeline. Moreover the object timeline, when not selected will be green. Look at this screenshot, where I kept the original generic names to clarify the type of objects.

Learning Interactions are internally interactive but as objects in Captivate they also come in the two flavors: static and interactive. You can recognize them by the presence of the Actions tab, with the possibility of scoring and reporting. However the score in the game interactions are not linked with the game results (see article)

Interactive interactions can also be identified, based on the generic name in the Timeline panel. In this screenshot I have inserted two interactions: Tabs (static) and Jigsaw Puzzle (interactive). Look at the generic names:

Look carefully at this screenshot: you see that both interactions also have a colored timeline, but exactly the opposite of what you expect. Please, support me by logging this bug. You may also wonder about the presence of a pausing point? No pausing point for the interactions? The static interaction has indeed no pausing point, you need to add an interactive object like a button, to keep the slide paused. That is needed to allow time for the learner to explore the interaction. However the Interactive Interaction doesn have a pausing point which is not showing in the Timeline panel, you’ll find it in the Timing properties.

Audio Problem

The question was about avoiding having slide audio still playing when the user clicks one of the buttons in the Tabs interaction. That interaction allows  to add audio to a button, which is object audio.  Only object audio allows simultaneously playing of multiple audio clips, either from object audio or, in this case, slide audio. Pausing the slide audio, when a button is clicked in the Interaction would need access to the source code of the widget, which is not available. I can only propose two possible solution to avoid hearing two audio clips at the same time.  I will only explain the first solution in this article. The second solution, with a custom interaction will be explained in a later article.

Interaction available after Slide Audio

This is the easiest workflow. The learner would not be able to use the Interaction while the slide audio is playing. With a normal interactive object that would be easy: disable it for a certain time with and On Enter action for the slide and enable after a certain time corresponding with the audio length. However, even an Interactive Interaction cannot be disabled! You need a workaround.

Steps:

1. Create a static image of the interaction, either using Captivate or another screen capture app like Snagit. Quality should be good to excellent.
2. Resize that image to the exact size of the Interaction.
3. Insert the image on the Timeline and time it for the duration of the slide audio.
4. Move the learning interaction to appear just after the image.
5. For a static interaction (like Tabs, Accordion….) you need to insert a button or click box to pause the slide. That is not necessary for an interactive Interaction.

Have a look at this screenshot of the Timeline, which illustrates the described steps:

• Slide audio, about 3,5secs long
• Tabs Interaction, starts at 3,4 seconds, extends till end of the slide
• Image of the Tabs interaction, same location and size, starts from the first frame and ends at 3,8secs; overlap with the Interaction is meant to avoid seeing the transition
• Click box – duration of the slide –  to pause the slide at its end; it could be a Next button as well.

Custom Interaction

Using shared actions, multistate objects, it is perfectly possible to recreate this interaction on a slide. At that moment you have full control over all objects. To avoid multiple audio clips playing at once, the easiest way is to use only audio started with ‘Play Audio’ command.  If you start a second audio with that command, the first one will be stopped automatically. For this example:

1. Use Play Audio with the On Enter event to replace the slide audio.  That is possible if you don’t need Closed Captioning.
2. Use Play Audio in the actions triggered by the Tabs buttons. Clicking the button will automatically stop the previous audio, whether it is the audio started On Enter, or the Audio started with another Tabs button. Object audio would also be possible, if you use the command ‘Stop Triggered Audio’ to stop the first audio clip started On Enter.

Do you want to see the setup for such a custom interaction? Post a comment, please.

Intro

In a previous post I explained the possible workflows to force the learner to view a slide completely before the Next button appears, but only on first visit. This new use case is similar but for another goal. Most courses will have narration explaining how to use the functionality of the course: how to navigate, how to use the TOC, how to pop up extra information, how to use a dashboard/dynamic menu etc.  When the learner is free to come back to those slides, it can be annoying if she/he has to listen to the audio again. To avoid this I will explain two possible workflows:

1. Using the On Enter event to trigger an advanced action, which will use the Play Audio command based on checking which visit it is to the slide. It is an easy workflow, with one drawback: for the Play Audio command it is not possible to use the Closed Captioning feature packed with Captivate.
    
2. Since Closed Captioning is only possible with Slide audio, this alternative workflow will use micro-navigation to jump to a frame after the end of the audio timeline. If you didn't read my introduction to Micro-navigation, please use this link. 

Both workflows can be watched in this interactive movie. Be sure to check out later visits by using the Back button. As explained in the previous post, we'll need a tracking user variable. It starts with a default value of 0 and is incremented with each visit to the slide. 

Workflow 1: Play Audio

For each slide where you want to use this action, you'll need a tracking variable. For the slide in the movie where this action was used, the variable was labeled v_visit_PlayAudio. Look at the Preview of the action, which is triggered by the On Enter event of the slide:

It has two decisions:

• TrackVar is not conditional, will increment the tracking variable (which started at 0).
• CheckVisit checks the value of v_visit_playaudio. If the value is greater than 1, which means it is not the first visit, nothing will happen (Continue), if it is not greater than 1, which means the first visit, the audio clip will be played.

Workflow 2: Skip frames

Look at the timeline of the slide with the Touareg salt caravan (Ténéré desert):

The Next button appears at 16,5secs. If the visit is not the first, all frames in 16,5secs have to be skipped. We need a tracking variable, which will be labeled v_visit_SlideAudio. It is not possible to reuse the variable which tracked the visits to the previous slide where workflow 1 (Play Audio) was used. I suppose  free navigation is possible, hence tracking visits will need a variable for each slide where you want to use the workflow. However, the variable v_skip, which is used to store the number of frames to be skipped, can be reused for each slide where you want to use this second workflow. It doesn't matter if you want to skip part of the slide to avoid an audio clip to be played the second time, or to avoid that animatios are playing the second time. As you see in this screenshot, the advanced action looks very similar to the one in the first post 'Force first view'.

It is so similar that it was possible to create this action as a duplicate from the one in the post 'First View'. If you are not familiar with duplicating an action, have a look at  Advanced Actions Dialog Box. 

Afterthoughts

Such a situation with two (or maybe more) similar actions,  immediately triggers this question for me: can I make this easier, can I save time if using this action multiple times. Two possibilities:

1. Change the advanced action so that the same action can be applied to both situations? There are two differences in the situations: the literal which is the duration in seconds to be skipped (was 10sec in the first post, 16,5sec in this timeline) Second difference is the tracking variable. For the literal a solution could be found, but that is not the case for the tracking variables because they have to be unique for each slide. This approach is not possible for the present situation.
   
   
2. Convert the advanced action to a shared action, with as little parameters as possible. That would also make it much easier to transfer the action to future projects, and as you learned from my webinar (see summary in this interactive movie) due to the presence o the shared action in the Library, much easier to manage. How to do the conversion and use the shared action, will be the topic of my last post in this sequence.
