Video Glitch on iPad
Apr 10, 2015
Hi All!
I have a short video inserted on every slide of a studio/presenter training. I used FLV as the video format because this reduces the size of the video. When the videos play on a computer, they work fine. When they are played on an iPad, there is a short glitch at the beginning of each video.
I have tried manually putting in a loading symbol in for one second and then have the video begin at the one second mark...thinking this would help buffering. I continue to get the glitch at the beginning of each video.
I have tried this in multiple environments with an iPad and an iPad2 with download speeds ranging from 9mbps to 18mbps and I continue to get the glitch.
Any advice? Should I increase the "fake buffer time" to 3 or 4 seconds? Some other approach?
Thanks in Advance,
Keith
p.s. I've talked to other developers who have experienced this issue, but I don't know anyone that has solved it yet.

Hi Keith,
I'm not sure what you mean by glitch? Just a delay in loading or something else? Presenter '13 does progressively stream videos as detailed here and if viewing on a mobile device it may be converted to a MP4.
Hi Ashley,
By glitch I mean that there is a small audio "blip" and the video starts one or two seconds in. (The first word or two is cut off.) This has been a consistent issue w/ videos in Presenter but because it is only on iPad's, this is the first client to be concerned enough to ask us to engage with Articulate for a fix.

Adding three seconds of "loading" before starting the video on each slide to allow for additional caching time appears to have remedied the glitch w/ most bandwidths. Not an ideal solution, but not too bad.
Hi Keith,
I'm glad adding a few seconds of loading time helps out with this situation. I'm looking to see if there is any additional documentation of this issue - but I'm not seeing it, so if you'd like us to take a look at your course set up we'd be happy to. You can package and share your Presenter files here.
Unfortunately the additional loading time does not remedy the situation in the Safari browser on iPad. I purchased a support incident but they returned the cost of the incident when they were unable to fix. If anyone has any creative solutions, I'm open to them!
Thanks Keith for sharing the update here. I see that my colleague shared this with our QA team so I'll include this thread as a part of that report filed as well so that we can share any additional information with you here.
