Would this swf solution work for an MP4?

Hi everyone.  Two of my videos that I uploaded months ago are suddenly having loading problems.  I'm trying to find the source of the recent problems, but it's like searching for a needle in a haystack.  Here is a link to one of my videos:  http://www.ezlifts.com/training/video_495C879521778/player.html

What happens is it pauses frequently, especially toward the end of the 2nd slide.  I never had that problem in the beginning, and I haven't uploaded a new version of the video or anything recently to make this happen.  It just started happening.

Well, one of our tech guys stumbled upon this older forum post on Articulate.  It says it's a solution for swf files, but would it work for MP4s, too?  I use MP4s for my video files.  Here is the link to that forum post:  http://www.articulate.com/forums/articulate-presenter/9100-script-movie-causing-adobe-flash-player-10-run-slowly-2.html

Help would be greatly appreciated!!

Hi Tammy. I'm not really seeing the issue myself but you may want to compare your movie's audio/video bitrate to the settings that would be recommended here:

Also, If there isn't audio on the MP4 file of slide 2, have you considered redoing that in PowerPoint? It seems like that would be a pretty simple set of slides to string together and that might resolve the issue altogether. You may want to try simply emptying your browser cache and relaunching the presentation to see if that helps.

Thanks Justin.  There is audio on the second slide.  Only audio, no video.  And that took quite awhile to sync up, though I wouldn't be adverse to trying it again and then reuploading it to see if that's the problem.

And when you viewed the video, you didn't see any pausing between the slides?  No extremely slow play back?  It's like we have half and half for our customers.  Some can view it just fine and the other half can't.  We also have every range of internet and computer speeds on both sides.  I have a 9 mbps internet connection here at work, but it plays really slowly for me and pauses in between the 2nd and 3rd slides.  Oddly enough, the exact same thing happened when I viewed another user's presentation.  It paused toward the end of the 2nd slide before finally going forward.  What could cause this?  Internet company?  Certain firewalls?

Hey Tammy. I'm in a location right now where I can't really listen to audio. Sorry about that. Can you please let me know if you have audio that is recorded in PowerPoint or in Articulate and the SWF or if the audio is embedded in the MP4file? If the audio and the MP4are separate, this may be what's causing the issue. If you can either:

  • Redo the MP4 so that the audio is incorporated in the MP4 file.
  • Do the whole animation/audio sequence in PowerPoint natively. 
I'm guessing that either of those would fix the issue you are seeing.

That's okay, Justin.  There is not any audio in the video itself that is embedded into the slide, but there is audio in the presentation itself, if that makes sense.  Its audio that was recorded using GarageBand 8 and then put into my Flash file.  I put the audio track on the top layer of the Flash file.  So, when the video/Flash file itself is brought into Articulate, it's combined as one file.  That probably is really confusing, so please ask for clarification if you need it.

And I would do the whole audio in PP and sync it with my animation, but that would take forever...  It's a lot faster to do it in Flash.  But since the audio and animation are in the same MP4 file, shouldn't that be fine?

Also, that wouldn't really apply to the first three slides.  I just have an audio file in those and did the animation in PP.  Just for the first three slides.  However, it's still pausing at the end of slide 2.  And I don't understand why the same thing would happen with a different presentation I viewed from another user.
