Synching a closed-caption layer with audio on the base layer

Hi, all. 

I'm working on a module with closed caption the user accesses by clicking on a "CC" button, which activates the closed-caption layer. The problem is that the closed-caption layer starts when activated and is not synched up with the audio, which is on the base layer, so I can't get the three text blocks in synch with the audio. Is there a way around this? Thanks!

Hi Shel,

I've found that syncing with audio in Storyline can be difficult. I would add the closed caption to your video. Then place a version of the video with the CC in one layer, and another version without in another layer. Play the version with or without CC based on the selection of your CC button.

Hi Shel,

I finished a CC solution, today. I tried starting a new discussion (my first) with the project file as an attachment, but nothing has been posted. I made a demo for my ID team, but it shows just the outcome. It’s not a step-by-step tutorial. I’m hoping that, eventually, the .story file will be made available for download and dissection. I’d like some feedback. Here’s a link to the demo:

I would be remiss if I didn’t give a big shout out to Matthew Guyan. It's his article that's the basis for triggering the text.

But, I wanted to have a CC button in the player controls where the general population would expect it, and have it toggle at any point in the playback.
