Question

Captivate 2017 videos on slides randomly have the ends cut early (cut off).

Hey everyone,

I've seen it posted before for older versions but the issue still remains so I'm going to re-ask the question. Our team will create a Captivate file with a few slides that contain video clips. When published as HTML 5, these video slides work fine. When publishing as video the ends of the video clips within the slide will get cut off. The amount of time cut off seems to be random. I have tried the following:

  • extending the slide to be longer than the video
  • changing the frame rate of the video (30fps is recommended)
  • turning advance compression on and off
  • adding extra slide frames to the beginning
  • changing the key-frame distance in the source video
  • renaming the source video
  • recreating the slide from scratch.
  • inserting the video into a new project
  • Changing the project skin and the player skin.
  • It happens to event and multi-slide synced videos
  • It can happen in a template based file or completely blank file (at one point I thought it was the template that we use but the issue finally happened in a blank file. It seems to be randomly occurring issue so far).
  • We are using h.264 video at 30 fps as recommended.

It's really frustrating as we need to have a HTML5 and Video version of all of our material. Right now we have to video capture from the HTML5 version. A real pain.

I've spent a few hours turning things on and off, trying to reduce the number of variables and I'm pretty sure it's something deep in Captivate and not the video files or anything we've done to our Captivate file. And the fact that in a brand new, blank captivate file the multiple videos we've tried have a 90% chance of having the ends cut off tells me that there's something wrong in the code. Even the same video file can sometimes work and sometimes not.

Anyone have any ideas?

I discovered this thread today (17 JUL 2022) when doing a Google search on "Adobe Captivate Interactive Video Truncated." I'm using Captivate 2019 (not 2017) and the problem is still there.

 

For context, here's what I'm doing and what I'm observing:

 

1. I create a video as an MP4 file (using a different screen capture tool, not Captivate).

2. I upload that MP4 file to Vimeo (to serve as the video host/streaming service because our LMS server is not as efficient at streaming video).

3. In Captivate, on a blank slide, I click on "Interactive Video," and I insert the Vimeo URL for the video.

4. I do this for all of the slides in my Captivate project, too. (And to clarify, a single Captivate project for me may have anywhere from 10 to 27 slides, each one with an embedded Vimeo link. Our Captivate projects consist *only* of a series of Vimeo-hosted videos. There's nothing else in our Captivate projects. We use Captivate only for SCORM publishing to work with our LMS.)

5. To publish the Captivate project as a SCORM .zip file, I select "SCORM 1.2" in the "Quiz Prefernces" window. (And to clarify, our LMS supports only SCORM 1.2.)

6. I publish the Captivate project as a .zip file using the HTML5 output format.

7. I upload the SCORM .zip file to our LMS and make it available to our clients.

 

The problem is: some of our clients have reported that sometimes the end of a given video gets truncated. Sometimes a given video is truncated by a few seconds. Sometimes it's truncated by a minute or two. And sometimes, that same video isn't truncated at all.

 

It's an inconsistent problem. Only some clients see this problem occur. And those clients see this problem occur only some of the time...even when playing that same video multiple times. It's very frustrating.

 

The only hypothesis that we've come up with that makes sense is the following:

 

When you embed a video in a Captivate slide from an external source (e.g., YouTube, Vimeo), Captivate queries the video source at the moment you insert it in a slide to determine how long the video is. Captivate then sets the slide duration to match the length of that video. Then, at playback time, Captivate doesn't actually know when the linked video comes to its natural end, it simply advances to the next slide automatically when the slide duration timer expires. And this could produce two possible problems:

 

1. If (for some reason) the video playback takes longer than its advertised duration (because of lag in the YouTube or Vimeo server), the internal Captivate slide duration timer will expire and advance to the next slide before the video playback actually finishes...and thus the end of the video appears truncated.

 

Or,

 

2, If (for some reason) the video playback takes less time than its advertised duration, the video playback will (actually) finish before the internal Captivate slide duration timer expires, and the result is that the video loops back to the beginning and begins playing again. Then when the internal Captivate slide duration timer expires, it ends that (second) playback of the video and advances to the next slide/video.

 

And yes, our clients have actually observed both of these problems. And both are explained by the same underlying root cause: the only communication between a published Captivate project and an external video streaming service (YouTube, Vimeo) occurs at the moment when you advance to a particular slide in the project. At that moment, the Captivate project follows the link you embedded  in the slide to trigger playback of that video...and that's it. From that point forward, there's no further communication with that external video streaming service while the triggered video is playing back, so the published Captivate project has no way of knowing when the video reaches its end; it advances to the next slide when its internal slide duration timer expires.

 

I did the Google search today and found this thread because I'm looking for a way to stop Captivate from automatically advancing to the next slide when the slide duration timer expires. Instead, I want it to wait for the user to click somewhere (either on the slide or in the Table of Contents) before advancing. In theory, this should solve the truncation problem.

 

What troubles me is that you reported this issue in 2018 using the 2017 version of Captivate. It's now 2022 and the problem is still there even in the most recently updated version of Captivate 2019. Doesn't give me a lot of confidence in Adobe's product support and customer service.

You may ignore this. Answers in this forum are given by other users. Avoid posting the same question twice, please! I have answered exactly the same question an hour ago in another thread. FYI as moderator and active user of this forum I get notifications about all questions and comments in threads I follow. And since I answer a lot of questions, avoiding seeing same question twice or even multiple times spares me some time.

If you don't get an answer, that means the problem could be not appearing that way for other users? I rarely use video as output, I want realy eLearning which needs interactivity

However, I pop in because of this sentence:  ....in a template based file ....

Are you talking about a file created based on a cptil file? Because at this moment there is a serious bug with cptl-files, I would recommend never to use them.

For the sake of (hopefully) users that could help you: which version are you using and on which OS?

Thanks for popping in. We do a bit of interactivity as well but we produce a video version both for archival as well as a proofing workflow. It's also great if someone has issues accessing the LMS, they can go to our video site and watch it there. 

I actually got on a call with Captivate support and ran through some troubleshooting. The issue happens whether or not we use a template file. We create our own templates and I thought that could be the issue.... something in our template could be causing the issue. But that's not the case. The tech that consulted with me could reproduce the same issue in a blank captivate project. That rules out templates of any kind being the culprit. 

Here's an oddity though. If the video was placed on a slide with no slides before it, it worked fine and did not truncate the video. If there was a slide before it, the video output would be truncated. This is in a blank project... as vanilla as could be mind you. This happens both in the windows and mac version of Captivate 2017 too (it's the most recent build).

Captivate support has bumped up the issue and said they should have some more info within 48 hours (I've heard that before unfortunately). But I do expect some response. I'll keep the thread informed.

I really appreciate your input btw. Any help to narrow this down makes a difference!

It looks like a loading issue, from what you explain about slides. SImiar isse can happen with long audio files which hae to be loaded on enter of a slide. There a possible solution is to delay the audio file a little bit on the slide. Did you try that for the videos? You could add a static image to bridge the gap. Just an idea.
