Hello, I have currently upgraded from Captivate 8 to Captivate 2017. When I publish the project to a MP4 file, the some parts of the audio return an echo- sound track repeats itself. Has anyone come across this issue before? Please help

Hi

I came across this while searching for issues I am having with Audio (question posted a couple of days ago)

I have tried moving the audio to leave a gap either side on the slide which was suggested. This work around is ok for Audio added to slide but the issue I am having is Audio added to captions on Video demo's the last three words are not being heard.

I am new to this so any technical advise would be gratefully received

That is indeed a different situation. Is the caption timed to be a bit longer than the duration of the audio clip?

No I have checked and the caption stays on the
screen for a couple of the seconds after the audio attached to it has finished.

I am so confused as the same slides in a different
project work fine. for this project as said previously I renamed the first project ad removed any slides that the second group of users wouldn't need to see.

Do you think it is anything to do with the way I have
published this project.

What would be the correct way/settings for
publishing the project to our LMS.

I used HTML/SWF

I continued to have this issue after many varied attempts and research of the technical requirements vs. those of my machine. After finding that my machine met (or exceeded) all requirements I opened a chat with Technical Support.

According to the technical support agent, this is a known issue having to do with screen resolution and the scale of the project. It had nothing to do with the length of the audio clips per slide, what program I was recording audio with, etc.

If others are running in to this problem, changing the scale of my project to a standard vs. custom size solved both the runtime error I was receiving and the audio doubling. It's unfortunate that this known issue hasn't been communicated. It's also unfortunate the visual quality of my project had to be reduced to publish correctly.

Really?! I've never heard that one before. Thank you for sharing it!

What was the custom size you were using? Was it a really odd proportion?

I can't imagine why the dimensions of your project would cause this issue...

If this indeed is a known 'bug', Adobe should put up an tech article on it.

Most my projects are default sizes but I certainly do custom sizes too...I'd be annoyed and stumped if I came across this, just as you surely were.

Thank you for posting this update.

Yes, it is an odd custom size (2254 x 1328). I pressed the technical support agent on the "why" but he just kept saying that it is a known issue but didn't give any details. I'm just so relieved to have a work around. I was so frustrated for about 2 weeks so I just wanted to share in case this may solve the issue for others.

Thanks for all of the advice!

I seem to recall that by nudging the audio a few milliseconds out on the timeline on each slide this can help with this or related issues. It has something to do with creating a small break between each audio file that prevents audio problems from occurring.

This does work in some instances. I believe where i am still having the audio compression issues is when a button is clicked within the video demo prompting another screen to display. This pop screen seems to effect the continuous audio on the video causing that echo. I've tried saving the course as a video and straight to You Tube as well, the same audio distortion happens intermittently throughout. The only thing i can think to try next is to re-record the video in pieces segmenting where the next screen will display.

Indeed, that could be the reason, due to the loading of the audio. Smaller is better at least for audio in Captivate.

I've not encountered that before, but there are reports of such oddities when upgrading projects, especially when not just from the immediately previous version.

Couple options:

Publish to SWF just to see if the issue remains. Is this something that happens JUST with MP4 export, or happens with SWF export too?

If your project isn't huge, open a new project, ensure the screen dimensions and preferences are the same, and try copy/pasting all slides from the upgraded 2017 version into the new project. It may take some adjustment to make it perform exactly like the original, but in the meantime you can at least do a quick publish test to see if the audio issue remains a problem in the new version.

Otherwise, how bothersome would it be to remove the audio tracks from each slide and re-add/sync them from the audio files in the library? Hopefully your audio files are well-titled, noting which file goes with which slide... Maybe try a such a replacement on a couple slides that show this problem, republish, and see if remove/re-adding the audio layers helps resolve the problem.

Thanks Erik for your feedback. The solution worked for one project but not for another.

I am having the same problem when publishing to MP4, the audio echoes or sometimes just disappears. I have re-recorded, even created a new project and still some slides error.
