Audio Skipping When Publishing F4V (w/fixed frame rate)

Dec 21, 2010 3:35 AM

I have been looking for help in this situation for a while with no resolve. Would love to have an answer why this is happening just with this file.

 

I have a simple project that is 63 slides long(+4 minutes), each slide has short audio assigned to the slide. All previews have no problems displaying and properly playing the video and audio. I get a problem when I go to publish the video as F4V with fixed frame rates. There are several hiccups in the audio(skips) like it is a CD or DVD being played that has scratches in it.

 

I updated Adobe Captivate to 5.0.1.624 yesterday (no change).

Made sure I restarted my Windows7 computer - No other apps running, still get the same issue.

 

This is one of the larger files I have created. And before if I have had an audio skip before I would go back and re-publish it with out a problem. This is not working for this file. If I save to regular F4V the audio is fine (not the video), SWF is fine, EXE is fine etc...

 

PC Specs (resources):

Windows7 64-bit

AMD Phenom II X4 820 (4CPU's) 2.8GHz

8GB of Ram

 

 

Anyone else experiencing this type of issue?

    I am experiencing the exact same situation. I have a very small (and simple) captivate file that I was using to test publishing formats in Captivate 5. At first, it seemed like the F4V with fixed frame was the solution we were looking for and then we discovered the audio skipping.

     

    I thought the audio problem might have been caused by using the Adobe Media Encoder to convert the F4V to FLV but then I discovered that you can hear the audio skipping as Captivate publishes to F4V.

     

    Have you found a solution?

    I'm also experiencing this issue. I've tried multiple publishing settings. I also notice it skips

    in the same spots.

     

    Anyone found a resolution yet?

    Thanks, I'll give it a try.

     

    Does that mean you are recording with the "Automatic" recording type? If so, what mode/mode settings are you using? Have you tried changing these or using Full Motion and playing with the FMR settings?

    I tried moving the mouse on the timeline with a bit of success.

     

    One thing I noticed is the skip usually happens under the "s" of the "Mouse" label on the timeline, and positioning the "s" over silence is the best way to avoid the skip. It's tricky in parts where there isn't a nearby silence to move it over, and sometimes takes a few tries to get it positioned correctly.

    Hi There,

     

    Follow these steps after you have updated(Help -> Updates) your copy of Adobe Captivate 5 to our latest update:

    a. Close Captivate and Open Notepad.

    b. Type the following text in the file:

    StitchPublishAudio=0

    c. Save the file (with the name AudioOptions.ini) in the Adobe Captivate installation folder.

    For example, C: \Program Files\Adobe\Adobe Captivate 5

    d. Open your project in Captivate and re-publish it.

     

    In case, you still see the issue then follow these steps (you would still need to install the update and save the attached ‘AudioOptions.ini’ file in Captivate 5’s installation folder):

     

    1. Open the project.

    2. Select the first slide.

    3. Scroll to the last slide and "Shift+Select " the last slide. Make sure that all the slides in the project are selected.

    4. In the Slide PI change the "Slide Exit" action from "Go to Next Slide" to "No Action". DO NOT DO THIS STEP for slides that have “Slide Exit” action set to anything other than “Go to Next Slide”  For eg- If a slide has the “Slide Exit” action set to “Open a File”, then do not change the “Slide Exit” action.

    5. Publish the project.

     

    Do let us know whether your issue gets resolved.

    I have applied the 5.0.1 update, saved the AudioOptions.ini file containing "StitchPublishAudio=0" into the captivate installation folder and changed all the slide exit actions to "No Action". None of these resolved the issue of the sound skipping at the end of some slides with mouse movements.

     

    Positioning the mouse movement on the timeline so the "s" in "Mouse" is situated over a silence is the only way I've found to eliminate the skips so far.

     

    Thanks for the suggestions though.

    I'm having a similar issue although on the slide where I get the skipping, I have no mouse visible.

     

    I tried the steps suggested by Manish but the outcome is the same - I get a skip in the audio in the same exact spot.

    I'm having the exact same issue. I have tried all solutions provided in this thread but nothing helps. Any news on how to fix this major issue? I can see this has been going on for quite some time now with apparently no solution.

    I am still in the trial period and is seriously considering NOT to buy this product after all.

    Hi Joel,

     

    Could you please re-send your email. For some reason I am not able to find it on my end.

     

    In the mean while do try these steps and update us:

    Manish,

    I shared it on acrobat.com to your maanand@adobe.com email address. I'm not sure how to resend the email, but here is the document URL:

    https://acrobat.com/#d=EEYB9aJ6fEJzhNTOtbvwgw

     

    As for the steps that you suggested, I've already done all of that (had to do those steps to fix the other problem of the last syllable of the audio being cut off on every slide).

     

    Thanks,

    Joel

    Manish, you never got back with me on this issue. Have you made any progress on this problem with F4V fixed frame rate causing audio issues? Did you receive my project that I shared with you on acrobat.com?

    I'm having the same issue as well. I've spent almost 2 days trying to trouble shoot this issue. I patched my copy of Captivate and added the AudioOptions.ini file with no luck. I set each frame to do nothing on exit.

     

    I have a project that was made from importing a PowerPoint presentation. There are 16 base slides and I added in audio to each of the slides. The final product is a little over 9 minutes long. I get audio skipping at random intervals. For example, the narrator will say the word "change", but when exported to a fixed frame rate f4v file, it becomes ch-change. If I manage to get that problem fixed, the skipping returns somewhere else in the presentation.

     

    I've tried exporting to a variable frame rate f4v file so I can convert it, but the Adobe Media Encoder sees it as a 46 second video file. If I take any .f4v files that were directly published by Captivate and attempt to convert them in Handbrake, Handbrake sees the files at 3 hours long, then encodes them to a useless file that's less than 1MB in file size.
