I cannot get closed caption text to display when I publish to video.

I have recorded a project using software simulation mode in Captivate 2017 and added closed captions to the slides that contain text-to-audio narration (on slide level). I have selected and formatted the CC option in the project skin and also added an advanced action to the project: cpCmndCC :=1

When I preview the project the captions display as expected, also ok when I publish to HTML5 / SWF. But when I publish to mp4 (our desired format) no text appears in the closed caption footer. I do see the banner at the bottom where the text should be:

I noticed that the option to select Video CC in the slides note panel is greyed out. I'm not sure why, or how to activate this option:

Can anyone help figure out how to get the closed caption text to display when published to mp4?

You can add it yourself using a vtt file.

Closed captions are part of the skin. When you publish to MP4 the skin is not included. Some sites have their own way of including CC (YouTube). You can add CC to a video included in a cptx project, but you'll have to publish it to HTML (or SWF).

Thanks for the responses.

I also read in other discussions that CC was possible in videos using the advanced action cpCmndCC :=1

Has anyone had success with this?

Sorry, you must misunderstand! Yuo can add CC to a video, when it is published to HTML or SWF output. The system variable cpCmndCC is not an advanced action at all. there is a big difference between variables and actions. It can be used to toggle CC off and On. Have a look at my blog post:

1 action = 5 Toggle Buttons - Captivate blog

I used a shared action in that post to create a custom toggle button for different features. If you only want to turn CC on, it can be done by toggling that variable to 1. Its default value is 0, which means that CC is turned off. Exception: in CP2017 it is now possible to turn it on by default in the CC settings.
