My inserted WMV video is ending prematurely

Jan 02, 2013

I have inserted a WMV file onto a slide.  When published and played the audio stops about 2 seconds before the normal end time of the video.

Original is 339 sec long.  Plays completely in the Windows Media Player.

Post-published MP4 file is also 339 seconds long.  Plays completely in the WM Player.

However, when the published content is run, the video only plays audio up to 337 sec mark. 

If I go into Video Editor in Storyline, and play the video, it too stops playing at the 337 sec mark.

Hi Greg!

Are you able to re-create this behavior with any mp4 file? What version of Storyline are you utilizing.

I tested the file that you shared, and see the behavior in Storyline 1 and upon upgrade to Storyline 2. I also see the behavior if I add the file directly to Storyline 2. 

However, I am unable to get this issue to occur with another file?

Unfortunately, there isn't anything different. They were cut from the same master, all sit in the same sub folder and are all imported the same exact way. It's interesting that others are having the identical issue. This appears to be happening once it gets into Storyline as the clips perform perfectly in otherwise. They are being brought into slide layers and not the base slide, but I don't think that is relevant. I am using a simple fade-in/fade-out animation. What do you suggest?

Hi Greg, 

We'll have to report this to our QA team to investigate further, as I can see the same behavior with your MP4 file but can't recreate it with my own files as Leslie previously mentioned. In the meantime, I'd look at editing the original video file to add some extra time at the end of silence so that even if the video is clipped it won't cut off any parts of the audio.

Just ran across this thread as I just experienced this same issue.  I imported 4 MP4 videos into 4 individual slides in Storyline and it either cut the video short or added an extra second or two.  I confirmed the MP4s were correct and the slide time shows correctly (same as the play time for the MP4s).  However, it cuts it off when previewing or playing the published version.  It's been trial and error manually changing the slide length to correctly fit the video length.  I created all the slides the same way and I experienced this issue with 3 of the 4 videos I imported (one was correct).

Hi Dave,

Thanks for sharing your experience here. This is something that we did send along to our QA team with the sample video files here, but it's not something that they've been able to track down the cause of yet as it seems to be specific to the video file. If you'd like to share a file with our team as well we're happy to include that in the report we've filed for continued testing - or if you're ok to continue with the workaround you mentioned, I will keep folks posted here if we hear anything additional from our QA team in regards to the behavior. Since you're responded to the thread you should be subscribed to receive the updates via email.

I'm having the same problem. It is getting reported to me some weeks after the module was posted to a server. I'm assuming the issue arose over time. Is there an answer to this problem? 

Here's the module:

The videos, which were encoded with an Adobe Premiere CC encoder, to mp4's, play to near the end and then just stop.

Also, the slide framing the video becomes detached from the player frame after viewing several videos and the submit button is missing from the test questions.

Hi Roger,

Thanks for reaching out. I'm sorry that you ran into the issue with your MP4s being clipped at the end. 

We have reported it to our team, and continue to keep an eye on it to evaluate how many customers are impacted and what impact it has on courses. The number of customers and depth of impact are two of the elements that help us prioritize bugs and fixes. 

This issue has been one we weren't able to replicate outside of the original projects, using our own MP4s. I'd want to take a look at your original .story file and know a bit more about which videos are causing the issues. Also I saw you shared the HTML5 link - can you tell me what browsers you're viewing it in?

Not sure if this would be a fix for all the issues listed on this thread but I did find a fix for one of my modules that I thought i would share.  I noticed I always had issues after editing the video.  Found out that even after you delete the video from the timeline and re-import the updated version, the timeline stays at the original video length.  Also, the re-imported video defaults to "show until end".  When I removed the "show until end" option,  I then saw correct length of the updated video (either shorter or longer than the original timeline depending on if we cut or added to the video).  I then manually lined up the end of timeline with the updated video length and it solved my issues as it related to cutting off or leaving dead space.
