Question

Preloading videos

Hi!

I have a project that is only be viewed on desktop and the file is loaded onto the machine. There are about 100 slides separated into about 10 sections. On the first view, videos will glitch and stutter at the beginning. On second view, they are fine. I'm guessing this is a loading issue. A couple of questions. Can I assume that once the entire presentation has been viewed on a machine, it will work properly on subsequent views, unless perhaps cache is dumped? Can I tell Captivate to preload the videos to help prevent the stutter on first video? If I have a preload, should I also dump the videos after viewing? Does it seem logical to preload all videos pertaining to each section during the section intro slide (and possibly dump the previous section videos)? Section intros are single stagnant slides with nothing going on, so it seems like a good place to put a preloader.

Thanks for help!

    My suggestion is to upload the videos to a streaming service like Vimeo or even YouTube. You can keep videos on these sites as unlisted so the only way people will see them is through your course. Here is a video I did awhile back on uploading and embedding the video using Vimeo. It works really well and loads instantly.

    Thank you for the suggestion, Paul. Unfortunately, we won't be able to use a streaming service as these devices will be used out in the field where internet and cell service may not be available.

    After further investigation, it seems the stuttering problem lies within the videos themselves. We are re-outputting to a lower bitrate to see that that helps.
