Audio Delay After Random Quiz Slide

Captivate PC Ver 7.0.0.118
I have text-to-speech audio narration on every slide which begins at .5 seconds. I have a random quiz question on slide X. On slide X+1, the audio narration takes a considerable amount of time to begin playing, upwards of 15 seconds when it should start at .5s.
I've tested many things. Ultimately removing the random quiz slide fixes the problem, but that is not an option. Moving the quiz slide backward or forward makes the problem consistent in which the audio is delayed on any slide which directly follows the quiz.
I've always set up my courses with intermittent quizzes for user engagement and have rarely encountered this issue to which I cannot find a cure. Any help would be awesome.
Thank you.
Jeff

Hi,
Based on our experiences, we have encountered similar behavior.
Because RDP was oroginally designed to flush the video frame buffer to the client about once every 100 milliseconds.  While this is fine for most Windows GDI applications, graphic intensive applications, 3D applications and applications requiring
audio / video synchronization don’t fare so well.  With respect to streaming media in particular, RDP is only meant to cache the bitmap files (compressed) not the audio which is uncompressed over the wire.
Quoted from this blog below:
Terminal Services and Graphically Intensive Applications
http://blogs.technet.com/b/askperf/archive/2009/04/17/terminal-services-and-graphically-intensive-applications.aspx
In addition, there are also a few suggestions within the blog which could improve RDP session performance such as update drivers, increase network bandwidth and frame rate on the client side.
Best Regards,
Amy

  • Random Quiz Slides not displaying in published files when on server

    version 4.0
    Output - swf\htm
    Hello
    Have been working on some elearning now locally for a while which combines straight slides then ends with random quiz slides.
    Have published locally to c:\ drive and tested the swf\htm files and they play and display fine . However have now published the files to our organisations elearning server so everyone can access and played them back. All works fine till you get to the first random question slide - its just a green blank screen ! The green is the same as the skin I have on the project as a whole.
    So basically the problem must be on the server. I have no idea what to try !!
    thanks in advance
    ps - just adding this bit, I meant to put it in quizzing forum but didn't . Can't see how to move it now
    Also just tried adding a normal quiz slide and that displays fine - its when I am using the random quiz slides from a pool. Thanks

    thanks for this - feel a bit thick now !
    I had no idea they created separate files. That serves me right for not working in separate folders when I am testing and working in the root of the directory (with about 50 other cp files in it !)as I missed it.
    Mystery solved - thanks again !

  • Audio delay after rendering

    Hello,
    I'm a YouTuber from Poland who puts on my channel movies (named commonly gameplays) from variety of games. I rendered about 250 gameplays using Premiere Pro CS5.5 and CS6. Except for the raw video from the game, I also render my gameplays adding the video from internet camera and sound of my voice from TeamSpeak (material from the game, camera and teamspeak are recorded separately).
    Recently I encountered a very wierd problem with my Adobe Premiere Pro CS6 - audio from the game is delayed after rendering movie. My voice is rendered as it should be with no delays.
    Everything was fine earlier, I had no problems! And I haven't changed (consciously) anything at all im my Premiere Pro CS6 settings nor in my hardware. What is more important, when I render only half of the sequence or some part, audio is okey and there are no delays - therefore this excludes a hypothesis about beeing something wrong with my recording settings. It seems that is happening only when I render video from the beginning...
    It may be important to say, that normally I record all videos with MSI Afterburner but recently I installed FRAPS on my computer. And than this problem came out. I have no idea how that may be related but it's just an observation. After instaling FRAPS I had another problem with memory paging file - games were closed when I recorded with MSI Afterburner due to insufficient virtual memory. Never had this problem either. I uninstalled FRAPS, reinstalled MSI, installed FRAPS again and now I don't have that problem. Another weird thing going on...
    Edit
    When I close Premiere Pro CS6 I receive a message that Adobe Media Core CS6 stopped working... may it be related?

    Tammy,
    If we've dropped a bit of time for this part of the edit, you now have time for more fun aspects of it.
    While I will casually monitor my Meters, I spend much more time with a good set of noise-canceling headphones, listening critically. The Meters are basically to point up potential issues. With Audio, if you have not invested in a really good set of headphones, do yourself a big favor, and sneak 'em into the budget.
    Glad that you got things toned down.
    Now, let's go on to Lesson 02 - The Audio Mixer. Unlike adding Keyframes to a Clip, when your cutting is done, you can apply Track Keyframes to attenuate (also Pan, etc.) you Audio Tracks to suit. One would just change the Send in that Track to Write, or Touch, and "ride the gain" with the slider, as is required. I probably do most of my Audio editing there, than addressing the individual Clips. First thing that I have done is cut back a bit on the frequency of the Track Keyframes in Edit>Preferences, as I find the default to add too many (and you can go in and adjust these by hand, if you need to "smooth" things out a bit.). One caution: do this when you are satisfied with the cuts, Clip placement, etc., as these Keyframes are applied to the Track. If you were to remove a Clip, and replace it, those Keyframes would apply to that new Clip, whether you want them to, or not. This trips some folk up, if they do the Audio Mixer thing too soon in the editing. Wait until you are "in love" with your Timeline otherwise. It's like scoring a Project. One does that as about the very last step, or much work will be repeated, and that is not fun.
    Good luck,

  • 1-2 Second Audio Delay after installing windows 7

    I installed windows 7 on monday but whenever i do anything that has audio it is always delayed by -2 seconds.
    For example when playing Dragon Age Origins an npc's mouth moves then a second latter the audio finally comes.
    When listening to music it isnot that noticable since it is just audio but when i pause or stop it the audio continues for -2 seconds.
    When watching videos on Hulu it is the same as games where the voice comes about -2 seconds after the person's mouth moves.
    I have everything up to date via the auto updater and checked on here to verify the correct drivers are installed and they are indeed the latest.
    Everything worked fine when i had vista but this issue may not be big to some but since i am a big very gamer this is a major problem and if not fixed soon i will remove the card and use the crappy onboard sound.
    Any help fixin this issue would be greatly apreciated.
    Edit: Forgot to mention that i use the creative sound blaster x-fi titanium card
    Edit: I managed to fix it by deleteing EVERYTHING Creative and using ONLY the newest driver from the site, however doing this pretty much makes my card nothing more than a fancy onboard sound card since it doesn't have any of it's features.
    The updater doesn't detect my card and when it does and i install anything from the list i get this audio delay issue.

  • Bluetooth Headphones Audio Delayed after Updating to Yosemite

    Ever since I upgraded to OS X Yosemite my Bluetooth headphones have started having pretty drastic delays on my iMac.  When I first start up the computer it seems normal, but after a half an hour or so, I have more than a 2 second delay.
    I googled it and found that lots of people have this problem, but I haven't found any fixes.  Is there anything I can do??

    I Just got an update on my bug report from Apple yesterday. They think they've fixed the bug in the next release 10.10.8.2.
    Hopefully this does the trick and it's just a matter of time Before we all get the update.
    I Havent been able to confirm the fix, but it's something!

  • Random Quiz Audio problem

    I'm having an issue with random quizzes in a module i'm developing.  If I place a random quiz slide in the middle of the project the next slide will not play the audio that is associated with it.  It goes through all the animation properly just does not play any audio.  I do not have this problem if I use a regular question slide.
    Any ideas what could be causing this.

    Hi,
    It is Version 7.0.0.118 and i'm running windows 8
    I have inserted the slide audio on both the slide and an object on the slide following my random question slides and neither will play, eventually when I get to the second or third slide following the quiz questions I do get audio back but it is off from the timing.
    Thanks,

  • CP7 - quiz slides continue to play after timeline

    I'm using quiz slides with audio in Captivate 7.
    The audio plays, I choose an answer and click Submit, then click Y to continue, and whether I'm right or wrong, the playbar is only 1/2 - 2/3 way through the slide.  So I have to wait while the slide plays out, long after the audio (and the slide) ends.
    The Results slide that follows is hidden, with the option turned off in Preferences, so the quiz slide is usually the last slide of the project.
    Does anyone know what's going on?
    Thanks for any help,
    Marion

    Default pausing point for question slides (and score slide) is half its timeline. With the default timeline duration of 3 secs this means that after the two-step process still 1.5secs has to go.
    Have a look at my explanations, and tweaking possibilities:
    http://blog.lilybiri.com/question-question-slides-in-captivate
    http://blog.lilybiri.com/question-question-slides-part-2
    You can move the pausing point more towards the end, but only with the mouse (there is no Timing accordion). Or you can change the Continue option to 'Go to Next Slide' both for Success/Failure.
    BTW this is nothing new, has always been the case. The posts were written for previous versions.
    I would recommend to add a last slide after the last question slide, it doesn't have to be the Score slide, certainly if you want to report to a LMS (allow little bit of time to CP)

  • Skip audio on quiz slide

    Hello Captivate Community,
    I'm a long time lurker / dabbler finally putting Captivate  to use in some "real" projects.
    I'm working with a quiz slide and I'm wondering if there is any way to control audio. I'd like the learner to be able to skip audio so I figured I could add a button to hide the audio object but I see that there is no way to add a button to a quiz slide.
    Any suggestions?
    Thanks,
    Rick

    Hello Lilybiri,
    Thanks for your response. I'm against using the mute button as this is a global setting and would force the learner to unmute for other slides. And I don't think your other suggestion will work for my course flow. My scenario will work like this: Learner arrives at quiz slide and audio plays narrating question and answers. If the learner answers incorrectly they are forwarded to a video remediation. After remediation the learner is returned to the quiz slide to try again. At this point audio plays again and I would like to give the learner an option to skip audio, but I see I am probably out of luck.

  • After burning a slide show, I get a skip in audio

    After burning a slide show, II get a skip in the audio about every 5 min. of run time.  I imported the pictures from i photo and the music from an itunes play list. When I play the entire thing in preview it runs fine with no problems, but after burning to a dvd, I get a skip every 5 min.  I burned to hp DVD-R (16x) and Memorex DVD-R (16x).  Still the skip.  I have burned to Best preformance, High Quality and Professional Quality.  I have even slowed the burn time to 4x.  Still the skip.  I noticed the bar at the bottom of the screen always reads 5 min. for the audio duration and when it goes back to 0 is when it skips.   The run time when I put the cursor on the audio well reads the correct 3min:35sec. 

    SlideShow function in iDVD - is limited to 99 photos per show.
    Creating the SlideShow in iMovie HD6 or FinalCut - doesn't limit this but offers 100% control over process (audio and transitions)
    Using iMovie'08 or 09 or 11 - will degrade picture quality as they only deliver every second line over to iDVD.
    I never use "Share to iDVD" in any iMovie version.
    • iMovie up to HD6 - Just close it and import movie project from within iDVD
    • iMovie'08 to 11 - "Share to Media Browser" and as Large (not HD) will give as good quality as they can do

  • Quiz slides inserted in project; subsequent slide has audio

    Hi,
    I inserted a couple of quiz slides, true/false and multiple choice, in between 2 regular slides that have audio. When I run my project, I see the quiz slide, but the audio plays as if the quiz slides are not there. In other words, the audio for the subsequent slide plays while the quiz slide is displayed. For example:
    Slide 1 has audio
    Slide 2 is quiz
    Slide 3 is quiz
    Slide 4 has audio
    When I play, my audio goes from slide 1 to slide 4, while displaying slide 2
    I know I must have some basic setting incorrect. My quiz slides are set to On Success - Continue. The surrounding slides are set to On Enter - Continue, On Exit - No Action.
    Help!

    In Captivate you can insert audio on objects, on a single slide, and across multiple slides.
    Is it possible that your audio has been inserted to span more than one slide instead of slide-by-slides?
    If for example you had originally added your audio to a number of timed slides, and then inserted more slides in between, you may have confused Captivate as to where the audio needed to play.
    I may be on the wrong track here but thought it worth suggesting.

  • How to add an audio click box on a quiz slide - adobe captivate 6?

    Hi,
    I'm trying to add an audio click box on a question slide. It works brilliantly on normal slides but theres no option to add a click box on quiz slides.
    I'm trying to add audio on click. So, when somebody clicks that area they will hear a sound. Is there a way to do this on a question slide?
    Thanks

    Replace those old click boxes by shapes configured as buttons. Have a look at this post:

  • Audio disappears after going backwards 10 slides

    I have 2 Captivate projects with 30 slides each and mp3 audio on all slides. The audio is imported To Slide. The slide does not advance after the audio finishes. The user needs to use a forward button in the navigation. Everything works fine moving forward. But if the user starts clicking backwards through the presentation the audio will stop playing after the 10th slide. And it doesn't matter where you start moving backwards. It could be slide 30, slide 23  etc. But after 10 slides the audio no longer plays. This problem seems to only happen with HTML5 output. Flash output doesn't seem to have the problem. Of course, our client wants to use HTML5.
    Any ideas?

    OK, I finally got around to testing my project and it does the same thing. This is a pretty serious issue if there is no work around. I'll log a bug.

  • Quiz slide not advance when using question pools and advance answer options?

    Hi,
    I am using CP 5.5. I created a small test where I have just 2 question in a question pool.  The questions are using the advanced answer options to show some specific feedback. When I insert the questions in to the project using a random question slide, after the user answers where you should be able to press Y or click to move on, I click, but nothing happens.  You can't get off the quiz slide.  The quiz slides work fine when they are inserted in the project as reqular quiz slides, but not when they are being pulled from a question pool.
    Is this a known bug? Is there a workaround? Anyone else run in to this?
    Thanks!
      Lori

    I was having the same problem on the last Random Question slide (total 10 RQ slides), and was able to fix it by following the next steps:
    Make sure Quiz: Pass or Fail actions are set to Continue for both Passing and Failing actions in the quiz preferences.
    Delete the RQ slide not advancing, then duplicate one of the RQ slides working, and assign your question pool to the new slide if different from the original duplicate. This step will make sure you are using a good working RQ slide.
    For some reason, my last RQ slide was corrupted and wasn't advancing to the Score slide at the end of the quiz.
    I can finally finish this project.
    Good luck.

  • Quiz Slides inserted into other slides??

    Is it possible to insert a quiz slide into another slide with content on it?  I have a short story in a series of about 11 slides, and would like the user to be able to answer some questions pertaining to the paruticular slides as they unfold.  Is it possible to manipulate a multiple choice question that is inserted in another slide, and/or can the question even be inserted into a story slide?  Thanks in advance!

    Hi Sabrina
    Accept my apologies for this late answer, last week has been very hectic. I will try to make it up, will send you a link to the example slide I did create if this is really what your wanted. You'll find a screenshot.
    I create a slide with a duration of 10secs. The drawing I created (SimpleDiagrams) is visible for the duration of the slide.
    To the slide an audio is attached (it is music here, but you will have a narration, that has a timeline of 7secs. After those 7secs, the question appears (see timeline screenshot). It has 4 Text captions:
    Question itself (How many men...), labeled it Quest1
    3. 4. The three possible answers, labeled Ans1_1, Ans1_2 and Ans1_3
    The answers are covered with 3 click boxes, CB1_1, CB1_2 and CB1_3. They do only have a Success Caption, deleted Failure as well as Hint Caption. The caption gives the feedback to the user (on the screenshot I show the feedback for the correct answer). All captions are in the same location, have same size. To each caption I attached the appropriate object audio. It will play when the caption appears.
    Finally I have a 'Next' button, that is initially set to invisible in the Properties, but will become visible when the correct answer has been chosen. You have to make sure that the pausing time of this button is after the pausing time of the click boxes. I labeled this button BtNext1
    I created 2 standard advanced actions, really simple ones:
    rewind to be attached to all click boxes that sit on top of incorrect answers; they will rewind the playhead so that it will not continue when the click box is clicked (which is the default behavior); since there is nothing specific to the slide object ID's, this can be reused on all question slides; action has one statement:
    Assign   rdcmndGotoFrameAndResume with rdinfoCurrentFrame
    success to be attached to the click box on top of the correct answer (here CB1_2); it doesn't have to rewind the playhead, but will show the button that pauses the slide again (a little bit later on the timeline because the pausing time is later than for the click boxes);  this action has a slide specific object ID (the label of the button), so you will have to duplicate it to have an instance for each slide, and change the button identification (label); to make editing easier I chose this typical label, you will only have to change the last character if you label your buttons with this logical names; this action has only one statement as well:
    Show  BtNext1

  • Advanced Action jumps Quiz slide pause point

    Hello,
    I have a project I have asked questions about in a previous discussion but as this is a new difficulty so I have started a new discussion. 
    The project in made up of only quiz slides and on each quiz slide there are:
    1 - 4 text boxes that are controlled by advanced actions with ss set as buttons....this part is working great.
    the quiz ...standard stuff
    and audio ...not working
    I created 2 groups and 1 ss set to function as a button.  Group 1 has an arrow and says "Play Audio" Group 2 has a square and says "Stop Audio".  On the first slide the action works great...just as I would like it to work.  After answering the question you then continue to the next slide and the audio works for three clicks...click to play, click to stop and then if you click again the slide jumps the pause point on the question slide and none of the buttons work on the slide at all.   It does not make a difference if you start the project form the beginning or from the middle, the problem is still the same.  The first slide works just as it should and the second slide jumps the pause point and you are shut down and can not continue. I am not able to click the submit, answer the question...nothing.  Any insight would be very much appreciated as once again, I am stuck.  I am not sure if the problem is caused by the fact that it is a quiz slide and there is something about the quiz slide itself that is causing the problem.  Or ... more likely, I am just missing something.
    Thank you.
    This is what the buttons look like.

    Advanced Actions and Groups, this was so helpful!

    You didn't watch the other video? It was about playing audio as well...Have also a long blog post about possible scenarios to play/pause audio. It is different, because it is about a real pause, not about replaying an audio clip as in your example:
    http://blog.lilybiri.com/toggle-shape-buttons
    Question slides are a different beast, you have always to be very careful there. I blogged about buttons on question slides:
    http://blog.lilybiri.com/want-a-button-on-question-slide-in-captivate
    The question slide objects have highest priority. I should explore this more in depth, but my intuition tells me that perhaps clicking on your shape button triggers the action that is performed as second step on the Question slide (press Y or click on the slide). Does it happen before  of after the user clicks the Submit button?
