Don’t let low bandwidth stop you from wearing that genious hat!!
You make a nice captivate movie with all jazz and background audio. And there pops up a hidden glitch – end users of your captivate movie are short on bandwidth. But you, Mr. genious knows it pretty well that you have pre-loaders in Captivate to your rescue. So you go ahead and set the pre-loader percentage to 10%. This would mean that the movie will start playing when 10% of the content has loaded, with the remaining content loading as the movie plays. Wow!! You punch the air and all that….
Next day you get your users complaining that your preloader ‘rocket science’ is not working at all. The movie content loads 100% before starting regardless of preloader setting. Amused?? What did you do wrong?? Confused??…well this post will help you.
your problem is…
Your movie has background audio across the movie. Ideally, as soon as the movie is loaded(after 10% preloading), the content should start playing. But to play the first slide, the associated audio is needed and since there is only one big audio file, Captivate attempts to load the entire audio file(irrespective of the slides) prior to play the content. And this eats up the bandwidth.
….and the solution is….
Inside Captivate, for each slide start the audio after 0.1 second. This prevents the audio to be stiched as one huge audio file in the final output. Consequently this would prevent the need to load the entire audio when you don’t intend to do so. And your content will start playing flawlessly with audio once 10% of the entire content is loaded (assuming that you set pre-loader=10%). Rest of the content loads in background.
So with this solution you could once again wear that genious hat. WOW!!
