Audio Video glitch
Jun 22, 2014
I'm experiencing a strange glitch in the audio of mp4 files that I have imported into Storyline.
At the beginning of each slide containing a video, a very short burp (that's really the best word I can come up with) of audio occurs.
It sounds a lot like the audio starts to play, and then stops...very quickly.
Like, a fraction of a second.
Then the video file plays correctly.
But it's on ALL my video slides, and I've never experienced anything like this.
It's NOT present at all in the source videos...only when they get into Storyline does this problem appear.
It happens ONLY when I preview or publish.
It does NOT happen when I play the video directly from the timeline, nor when I am within the Articulate Video Editor dialogue.
So far I've tried:
Re-encoding the file at a different audio bit rate (no luck)
Changing the transition (I initially was using a PUSH, but I've also tried a fade, and NO transition...same thing).
The only thing that I've managed, as a workaround, is to re-encode the video files to contain no audio, and then import the audio and video separately (I created the videos using Camtasia, where I combined screen-capture and VO).
I really don't want to re-encode and re-edit media for 68 slides.
