Change video speed and have closed captions

[#1]

I have a simple javascript var myVideo = $('video');
myVideo[0].playbackRate = 0.5; connected to a button on a video in a multiple slide project with fluid boxed

s. The added javascript does indeed work and allow users to slow the video down. However, when a user clicks on show closed captions the closed captions are then off-sync with the video. How can I make it that the closed captions slow down/ speed back up depending on whether a user is playing the video at 0.5x or 1.0x?

OK I contacted Adobe and they said to see our Javascript specialist! Well, as the script is so simple, I tried to find the solution. I have this javascript working on slide video in a fluid box presentation. The simple solution was to make sure for the speed buttons that the "Continue playing the project" button was checked. The captions now sync correctly.

Makes sense. Thanks for sharing.
