Audio Video glitch

Hi George,

A couple of things:

Where is your project file for Storyline located? Are you working with it locally?

• Work on your local drive (your C: drive). Working on a network drive or a USB drive can cause erratic behavior, including file corruption, loss of audio, and other unexpected behavior. 
• You should also make sure the directory path to your project files and your published output is less than 260 characters (for example C:\Articulate).
• Avoid using special characters, accents or symbols in your file names (this includes spaces and underscores).

Additional information regarding "Naming Files, Paths, and Namespaces" in Windows operating systems can be found in the following Microsoft article.

Also, please make sure you're importing the MP4 files from a local source, as well. 

Please make sure you're running the most recent version of Storyline. Articulate Storyline Update 5 includes bug fixes, performance improvements, and HTML5 output enhancements. Click here for details.

If you still see this issue, are you able to share one of the MP4 files here, so we can take a look?

Thanks!

Thanks.

I'm definitely working on a USB drive...though thru a hi-speed connection.

I'll see if switching to a local drive helps.

My workaround has proven to be not all that cumbersome...though I'd prefer a straight solution

I've often worked off USB, and never had this issue...so I guess there's a first time for everything.

Hi George,

Please keep us posted if working off a local drive on a brand new file continues to exhibit this behavior. Although you haven't run into a problem before with a USB drive, it's a known cause of erratic behavior and file corruption as Christine mentioned - so we'd obviously want to avoid that! You could also try importing your existing course into a new course as described here to resolve any odd behavior. 

I have a similar problem right now. I inserted several mp4 video with audio tracks in slides, and after publishing, each of these slides playback the audio (contained in the video) with a small "jump" at the beginning. I checked the source mp4 and the published mp4 (in "story_content" folder) and there is no problem with audio in them, however in playback the "jump" occurs at the beginning each time.

Hi Zio, how are you testing your published content - locally, on the web, or in an LMS? To properly test your published content, you'll want to upload it to the environment for which it was published. 

Do you also notice this behavior in Preview mode within the file?

Hi Alyssa, thanks for answering, I'm testing on a local webserver (XAMP) as I always do, this bug occures on every video that has audio starting from the beginning. I asked other developers and everyone confirmed to me it is a known bug of the video player of Storyline. The only workaround they found, is to insert audio (inside de mp4 video) after at least 1 second from the start. It seems that in the first moments of loading, the video player is calling some actionscript that causes the "jump" of the audio track...

Hi Zio,

Thanks for that detailed update. If there is anything we can do to further assist, please let me know!
